Top Ways to Save Energy at School

The issue of saving energy amid the exponential advancement of the technology-dependent studying process is one of the critical challenges school systems face today. Modern students are avidly embracing energy-powered tools in class, from learning the techniques of successful coursework writing service on popular websites like EssayShark, to sharing their studying notes with peers via file storage services like Google Drive.

On that account, the matter of energy efficiency at schools has taken on unprecedented urgency, weighing heavily on school boards to be absorbed in how to minimize electricity consumption. This has led school authorities to employ a great variety of solutions aimed at mitigating the destructive impact of environmental pollution. Following the universal eco-inspired trend of reducing the use of electricity, we handpicked the most productive ways of saving energy for you to employ at your school!

Utilize LED Lighting

Replacing incandescent light bulbs with more innovative and energy-efficient alternatives like LED or CBL lamps is the perfect solution to start saving energy at your school. Powered by light emitting diodes, which is what this acronym stands for, LED lighting consume a lot less energy than traditional fluorescent lighting and have a much longer lifespan. This makes this type of lighting highly efficient for school. While incandescent light produces too much heat, LED light bulbs preserve it, preventing you from splurging money on cooling.

Another way to promote energy savings in schools is to use LED screens as they consume less energy and help in power consumption.

Give Preference to Natural Light

Not only will sunlight cut the electricity costs your school pays, but it will also create a favorable learning environment for students as opposed to light bulbs. Following several comprehensive studies, sunlight allows people to stay focused on their tasks longer and is thus one of the key factors in promoting a healthy studying process. In order to make the best of natural light, you can equip your classrooms appropriately, such as using suitable blinds or curtains.

Consider Advantageous Cooling Options

Air conditioning provides total salvation for people when it’s boiling hot outside. And its role gets especially critical when it comes to a score of students sharing a stuffy home room during scorching weather. But, no matter how beneficial the effect produced by an air conditioner might be, this system consumes way too much electricity. Adopting effective cooling solutions is the key to saving energy and keeping it cool in your educational institution.

Use Sensors to Regulate Lighting

For safety reasons, many schools keep the lights on in the premises for the entire day. This is by far the least reasonable option to adhere to if you want to minimize electricity consumption. As an efficient alternative of providing your students with constant lighting, you can contemplate using motion sensors.

These devices can make the lights go on only if there’s someone in the room and off once the room is empty. Motion sensors are designed to detect motion and can thus automatically trigger lighting if there’s a need, instead of keeping the lighting unrestrained for the whole day.

Keep the Doors Closed

As another effective trick for reducing thermal loss in your classroom, keeping the doors closed will also maintain the coolness of the room. Thus, this practice can save you some good cash you would be forced to spend on a high-end air conditioning system.

Modernize the Kitchen

The school kitchen is veritably the hub of its electric appliances. Here you have ovens, a microwave, fridges, freezers, and the works. All these devices use a great deal of electricity and, based on the funding schools get from the government, most of them are probably old, which doubles their energy inefficiency. For this reason, replacing your kitchen appliances with newer and more cost-effective models will resolve some of the school’s energy consumption issues.

Drawing the Line

By following today’s all-embracing path toward saving energy, school authorities demonstrate their regard for environmental problems as well as their money management acumen. The modern technology-driven world offers us a variety of options to create a more energy-effective environment, improving the quality of our lives. The essentials we have provided in this article will help make your school routine less costly and more up-to-date.

Biomethane Utilization Pathways

Biogas can be used in raw (without removal of CO2) or in upgraded form. The main function of upgrading biogas is the removal of CO2 (to increase the energy content) and H2S (to reduce risk of corrosion). After upgrading, biogas becomes biomethane and possesses identical gas quality properties as  natural gas, and can thus be used as natural gas replacement. The main pathways for biomethane utilization are as follows:

  • Production of heat and/or steam
  • Electricity production / combined heat and power production (CHP)
  • Natural gas replacement (gas grid injection)
  • Compressed natural gas (CNG) & diesel replacement – (bio-CNG for transport fuel usage)
  • Liquid natural gas (LNG) replacement – (bio-LNG for transport fuel usage)

Prior to practically all utilization options, the biogas has to be dried (usually through application of a cooling/condensation step). Furthermore, elements such as hydrogen sulphide and other harmful trace elements must be removed (usually trough application of an activated carbon filter) to prevent adverse effects on downstream processing equipment (such as compressors, piping, boilers and CHP systems).

biomethane-transport

Although biogas is perfectly suitable to be utilized in boilers (as an environmental friendlier source for heat and steam production), this option is rather obsolete due to the abundance of alternative sources from solid waste origin.

Most Palm Oil Mills are already self-reliant with respect to heat and steam production due to the combustion of their solid waste streams (such as EFB and PKS). Consequently, conversion to electricity (by means of a CHP unit) or utilization as natural gas, CNG or LNG replacement, would be a more sensible solution.

The biogas masterplan as drafted by the Asia Pacific Biogas Alliance foresees a distribution in which 30% of the biomethane is used for power generation, 40% for grid injection and 30% as compressed/liquefied fuel for transportation purpose (Asian Pacific Biogas Alliance, 2015).

For each project, the most optimal option has to be evaluated on a case to case basis. Main decision-making factors will be local energy prices and requirements, available infrastructure (for gas and electricity), incentives and funding.

For the locations where local demand is exceeded, and no electricity or gas infrastructure is available within a reasonable distance (<5-10 km, due to investment cost and power loss), production of CNG could offer a good solution.

Moreover, during the utilization of biogas within a CHP unit only 40-50% of the energetic content of the gas is converted into electricity. The rest of the energy is transformed into heat. For those locations where an abundance of heat is available, such as Palm Oil Mills, this effectively means that 50-60% of the energetic content of the biogas is not utilized. Converting the biogas into biomethane (of gas grid or CNG quality) through upgrading, would facilitate the transportation and commercialisation of over 95%  of the energetic content of the biogas.

Within the CNG utilization route, the raw biogas will be upgraded to a methane content of >96%, compressed to 250 bar and stored in racks with gas bottles. The buffered gas (bottles) will be suitable for transportation by truck or ship. For transportation over large distances (>200km), it will be advised to further reduce the gas volume by converting the gas to LNG (trough liquefaction).

Overall the effects and benefits from anaerobic digestion of POME and utilization of biomethane can be summarized as follows:

  • Reduction of emissions i.e. GHG methane and CO2
  • Reduced land use for POME treatment
  • Enhanced self-sufficiency trough availability of on-site diesel replacement (CNG)
  • Expansion of economic activities/generation of additional revenues
    • Sales of surplus electricity (local or to the grid)
    • Sales of biomethane (injection into the natural gas grid)
    • Replacement of on-site diesel usage by CNG
    • Sales of bottled CNG
  • Reducing global and local environmental impact (through fuel replacement)
  • Reducing dependence on fossil fuel, and enhances fuel diversity and security of energy supply
  • Enhancement of local infrastructure and employment
    • Through electrical and gas supply
    • Through Fuel (CNG) supply

Creating an Eco-Friendly Project Site

Creating a worksite for construction is already a tough task, you have to get all the workers, tools, set up transportation of resources and materials, source the whereabouts of where this will take place, and more. It can be daunting at times, as you have a lot to plan and think about, plus the costs can be outrageous.

What’s even harder is planning it to be an eco-friendly site, as more people are in a rage about making things environmentally friendly; from power to materials, to transportation, they’d want it all to be as safe and protective of the ecosystem as possible. Luckily for you, you don’t have to look every to figure out how to do so, because you can look here.

Creating an Eco-Friendly Project Site

Finding Sustainable Materials to Work With

When you think of construction and building, you’ll often think of a workplace, workers, cement mixer, pallets of materials, and much more. While this is true, to create a more eco-friendly site, you’d want to start by thinking about what kinds of materials you are using and should you be using.

There are many different materials that you can use in place of concrete or commonly found materials that are not good for the environment thanks to the gases or pollution that they cause. These materials can include bamboo, straw, recycled plastic, and much more.

Manage Powered Equipment More Effectively

Powered equipment can take a great toll on the environment since it uses mass quantities or electricity to remain powered. What’s worse, is most worksites will keep their lights, tools, and everything else on while they are no longer working, or while on break. While this may not seem so bad, this can affect the use of electricity horribly and do damage to the environment.

If you want to become more eco-friendly, ensure your workers are managing their electricity correctly, shutting their tools and lights off when not in use, and opting for more eco-friendly ways to work. This can be difficult to do, but will greatly decrease the effect and use of electricity and harm on the environment.

Try to Conserve as Much Water as Possible

Water is one of the most overused and overlooked resources when at a job site. Water can be used for basic toiletries, cleaning materials, and many other ways. One of the best ways to conserve and repurpose water would be through the use of collected rainwater.

While it may seem a bit off, you can build rainwater collection systems that allow you to repurpose, irrigate, and use water that would have just been discarded or thrown away. This gives you a source of water that is usable but most likely shouldn’t be consumed.

Recycling from Construction Materials and Demolition

Let’s face it, you are going to have a lot of construction trash, broken materials, or unused materials left over from the job site, and you are most likely going to hire some person to quickly pick it up and haul it away. While this is a cheap and easy thing to do, the better choice would be to recycle or repurpose these materials.

Recycling of Construction Materials

You could hire a recycling company that will take these materials away, harvest what’s usable, and then repurpose them for future use. Or if that’s not your fancy, you could donate them to another work site yourself, and they can take these busted materials off your hands and purpose them themselves. Lastly, you could just repurpose a need or use of the material and not let anything go to waste.

Maximize Use of Natural Light and Energy

A way to conserve and maybe even build energy rather than just use it would be to think of your natural sources of energy and light. During the day you won’t need much light as the sun will give you natural light at all times it is out. And a way to use this energy to your advantage and even build a reserve would be to invest in solar.

Solar energy allows you to use the power of the sun, and as technology advances more companies are looking into creating tools and other ways to use solar or more eco-friendly energy conserves. A reserve of energy would not just help the environment but also save you money.

Reduce Carbon Footprint on Transportation

Moving materials from one place to another can cause a huge increase in carbon production which would hurt the environment. To make the most out of becoming more eco-friendly, try to see if you can manage the use of transportations correctly, or switch to an eco-friendly fuel.

As time advances and many more eco-safe or eco-friendly companies start to come to fruition, more and more are looking into the use and design of more environmentally sound fuels for vehicles or tools. This could be solar power or bio-based fuels that can reduce this carbon footprint.

Planning for a Sustainable Work Site

There are a lot of things to keep in mind when planning or setting up your work site. More is added when you have to start considering all the different ways to make the job site more eco-friendly to appease a bigger crowd that is steadily growing in their desire for environmentally safe construction sites.

While it may be a lot to consider, or even think about while trying to make your project site more eco-friendly, there are many ways you can start doing this. These include finding sustainable building materials that would be more environmentally friendly, conserving the use of electricity, saving water, and even maximizing the use of natural energy sources, recycling what you can from leftover materials or demolitions, and even reducing your carbon footprint by investing in eco-friendly fuel and ways of transportation.

While it is a lot to think of, don’t be afraid to plan this journey out slowly, and take small steps to become more eco-friendly at the job site. Even the smallest steps make a great impact and will slowly add up.

More Reasons To Check Out Alternative Energy Sources

In recent years, the world has seen significant economic progress, which greatly relied on energy fueled by coal and petroleum among others. With the continuously growing demand for energy, it is a fact that these energy sources may be depleted in the near future. Apart from this, there are several other reasons why humankind already needs to find alternative energy sources.

Global Warming

It is a known fact that different manufacturing processes and human activities, such as using vehicles, cause pollution in the atmosphere by releasing carbon dioxide. Carbon dioxide traps heat in the earth, and this phenomenon is known as global warming. Global warming has several harmful impacts such as stronger and more frequent storms, as well as drought and heat waves. Renewable energy sources such as wind, solar, geothermal, hydroelectric, and biomass to name a few, all generate minimal global warming emissions.

Wind power, for instance, has the capability to supply energy with a significantly lower emission compared to burning coal for fuel. This is the reason why wind energy is more beneficial compared to carbon-intensive energy sources. Still, the emissions generated by wind power are even lower compared to other renewable energy sources such as solar, geothermal, and hydroelectric power sources. This makes a huge potential for wind power to sustain the world’s energy demands, while preserving the environment.

Public Health

It goes without saying that the pollution caused by burning coal and fuel not only has an environmental impact, but it also has a significant effect on public health. Various diseases and ailments can be attributed to pollution, which usually affects the respiratory tract. Contaminated water also causes various bacterial infections. Wind power, solar energy, and hydroelectric systems have the capability to generate electricity without emitting air pollutants.

Additionally, wind and solar energy sources do not need water to operate, thereby, eliminating the probability of polluting water resources. Clean air and water that is free from pollutants, will have a significant positive impact on public health.

Constant Energy Source

While coal and fossil fuels are on the threshold of depletion, renewable energy sources are inexhaustible. Wind can be a constant energy source and no matter how high the demand for energy will be, the wind will not be depleted. In the same manner, as long as the sun shines bright on earth, there will always be an abundant solar energy source.

Fast-moving water that can be translated into hydroelectric energy, the earth’s heat that can be converted into a geothermal power source, as well as abundant plant matter that can be used as biomass, can all be constantly replenished. These can never be fully exhausted no matter how great the energy demand will be. The utilization of a combination of each of these energy sources will prove to be even more beneficial. Additionally, with its continued use, there will no longer be a need for combustible energy sources.

Lower Energy Costs

The cost of electricity continues to be a burden on the earth’s greater population. The use of renewable energy sources to light up the earth is considerably cheaper and inexpensive compared to the cost of burning fossil fuels for electricity and other energy needs. Apart from a cheaper cost, renewable energy sources can help stabilize to cost of energy in the long run, with an unlimited supply being able to cater to greater demand.

While it cannot be denied that setting up clean energy technologies comes with a cost, it can be noted that the cost of its operation is significantly lower. Conversely, the cost of coal and fossil fuels for energy consumption fluctuates over a wide range and is greatly affected by the economic and political conditions of its country of origin.

Economic Benefits

Fossil fuel technologies, often, revolve around the capitalistic market. Hence, the use of combustible fuels is often linked to unfavorable labor conditions, and even child labor and slavery. On the other hand, the use of renewable energy sources provides decent jobs, contributing to several economic benefits and aids in decarbonizing the future.

For instance, workers are needed to install and maintain solar panels. In the same manner, wind farms employ technicians for maintenance. Thus, jobs are created directly in parallel with the unit of energy produced. This means that more jobs will be produced if more renewable energy sources are utilized.

Reliability

Clean energy sources, specifically wind and solar power, are less susceptible to large-scale failures. The reason behind this is that both wind and solar power both employ distributed and modular systems. This means that electricity will not be totally cut off in instances of extreme weather conditions because the energy sources powering up the electricity is spread out over a wider geographical area. In the same manner, there will still be a continuous supply of energy even if certain equipment in the entire system is damaged because clean fuel technologies are made up of modules such as a number of individual wind turbines or solar panels.

With all the reasons to check out alternative energy sources, it still holds true that there remain several barriers that hinder the full implementation of renewable energy technologies. Some of these challenges are capital costs because of reliability misconceptions, as well as a difficult market entry due to an unequal playing field.

Because renewable energy sources are cheap to operate, the bulk of the expenses in its implementation is building the technology. Thereby, the rate of return for capitalists and investors in the market entails a longer waiting period. Adding to this barrier is the hidden political agenda that most governments need to overcome.

Economic progress and advancement in technology are not at all bad. On the contrary, it has brought forth a lot of benefits such as cures for ailments and diseases, resources for deep-sea or space explorations, as well as meaningful collaboration and communication. However, this progress came with a price, and unfortunately, it’s the world’s energy resources that are on the brink of exhaustion. Hence, mitigation has been already necessary and finding alternative energy sources is just one of the probable solutions.

Solar-Powered Pumps are Game-Changing for Agriculture

The first thing that comes to mind when you hear solar power is a solar panel placed on a rooftop for creating electricity for commercial or residential use. However, solar power has another important function – to mine and deliver water to improve productivity. This is especially applicable in sunny nations like Australia and most countries in Africa since its main industry is agriculture. Still, their productivity is suffering since their fields don’t get sufficient irrigation. Though, using solar pumps, they can double or even triple their profits. These economic gains can improve the lives of many farming communities.

Importance of Water in Agriculture

Our lives depend on clean water. The developed countries can sometimes take water for granted, but the evolving economies understand the significance of this commodity. A solar pump is an ecological option to get water for the crops and deliver drinkable, clean water.

The founder and CEO of the British-American company Ignite Power, Yariv Cohen, confirmed that solar pumps brought more efficiency, leading to bigger disposable income and more employment. Farmers can now grow three seasons per year instead of one. So, disposable income increased by 20% to 30%.

60% of the Sub-Saharan Africa population is employed in agriculture. Therefore, agriculture is accountable for 60% of economic output. This is less productive than the other regions in the world since only a part of the farmland gets constant irrigation – just 6% across Africa. Most farmlands go without irrigation, so most farmers in Africa rely only on rain for the larger lands, while they take care of the smaller areas with manual effort.

What is Solar-Powered Pumping System

The solar-powered pumping systems include a solar panel array, which fuels an electric motor. The motor, in turn, fuels the surface pump. The water is pumped from the stream or ground into a storage tank, utilized to water crops. If the farmland is irrigated consistently with solar pumps, the farmers will double the production compared to farmlands irrigated by rainwater or with manual effort.

Life-changing mechanism

About 600 million who live in Africa don’t have consistent electricity access. This is damaging the economic health of the continent. Everyone knows the ideal solution is to expand the electrical grid, but financial and geographical considerations prevent that. Ignite Power provides off-grid solutions to African countries in rural places like Nigeria, Mozambique, Rwanda, and Sierra Leone.

Cohen explains how solar pumps allow the farmers to irrigate their lands by using the sun. They first connect the homes, and then they utilize the same solar panels to water the fields. Using solar power, the pump enables a big area to be regularly irrigated. This improves the yield affordably.

Ignite Power has 1.1 million customers in Africa. So, there is room for enormous growth for his company and other providers of solar power in the continent. Cohen aims to reach 500 million houses.

They work with the bank and try to find the ideal solutions. They want to provide the best solution for the country with the help of the government. They can connect any payment providers or manufacturers to their system. They can connect all the suppliers, so many people could join.

The case of the two Rwandan women Grace Uwas (23) and Tharcille Tuyisenge (20) is admirable. They started working with Cohen’s company and bought solar systems for homes in Rwamagana, so people there have sustainable and safe electricity. Until now, they have installed twenty-five solar systems and more are coming!

Bottom Line

Electricity is the quintessence for any country. The solar power is game changing for African evolving communities to get access. In this way, they won’t just keep their lights on, but their agricultural productivity will be improved.

4 Amazing Benefits of Using Natural Gas for Your Home

Homeowners have a variety of energy sources to choose from to power their homes. Each kind offers its own set of benefits and disadvantages. When you are wanting to be more eco-friendly with your energy consumption, there are many benefits of considering natural gas as your go-to energy source.

Uses Of Natural Gas

Natural gas is non-toxic, colorless, odorless and the lowest-carbon hydrocarbon. It can be used for heating and cooking purposes in both residential and commercial settings. It can also be used to fuel power stations to create electricity for use in businesses and homes.

Natural gas can also be found in many industrial processes to create goods and materials from clothing to glass. Plastics and paints are some important products that have natural gas as a crucial ingredient. The uses of natural gas are many and diverse.

Benefits of Natural Gas

Below are some of the top benefits of natural gas to understand.

1. Affordability

In most areas, natural gas is much more affordable than electricity for heating your house and your water. For the same heating tasks, natural gas can cost almost half as much as oil or coal when used as the energy source. Natural gas is a deregulated utility. This means that consumers have fewer restrictions and are able to have control over how much they pay for the gas. Affordable natural gas prices mean a lot of savings throughout the year for homeowners.

2. Eco-Friendly

Natural gas is not as eco-friendly as renewable energy sources like wind and solar. However, it is the cleanest form of fossil fuel available. When compared to coal, natural gas releases almost a third less carbon dioxide and half as less than oil when it is burned. Compared to other fuels, it also lets off little to no sulfur.

3. Dependability

Using natural gas as your energy source is more reliable and dependable for your energy needs. When a big storm hits your area and the power goes out, you will not be able to depend on any appliance that runs off of electricity. For some homeowners, this means no lights, air conditioning, heating or hot water until the power is restored. When you run your appliances using natural gas, you can still operate them when your power is out.

When you have water heaters and other important home appliances operating using natural gas, the gas is often fed to your home in underground pipelines. This allows your energy source to be safe and well-protected from extreme weather conditions such as heavy storms. If you lose electricity, you will not lose all of your comforts while waiting for the power company to fix the issues.

4. Domestic Energy Source

Much emphasis is put on finding energy sources locally instead of having to depend on foreign oils. In addition to being more abundant and economical, relying more on local energy sources is great for the economy and creates more jobs and revenue.

Learn More About Using Natural Gas In Your Area

If you are looking to turn your home into an eco-friendly environment, turning to natural gas can be a great place to start. Natural gas providers offer plans and pricing options that can be suitable for all homeowners and budgets. Allowing most or all of your appliances to receive energy derived from natural gas can bring you many rewards as a homeowner and someone who cares about their impact on the environment.

This alternative energy source over oil and coal will be good for the global community for generations to come. The use of natural gas is on the rise and will become more competitive as consumers and energy providers look to reduce the impact on air pollution and the environment.

Why Going Green Is The Best Thing To Do For Your Community

As we go about our daily lives, it’s always a good idea to think about how we can contribute to the community we belong to in tangible and appreciable ways. Improving our communities from the inside not only allows us to make things easier and more convenient for ourselves, but also for the people we meet and rely upon in our day-to-day. Besides this, it also helps us think of other people’s needs rather than just our own—an essential need if we’re to live happy and productive lives. One of the best ways of improving our communities is, of course, going green: the act of adopting an environmentally-friendly lifestyle. This means taking active steps to minimize our carbon footprint and reducing waste.

It doesn’t have to start out big—we can start with the smaller things, and work our way up from there. Instead of buying new printer ink cartridges, for example, we can try using compatible ink cartridges instead. These are ink cartridges that are made the same way as new printer ink cartridges, but cost way less to make than branded ones. Instead of throwing away our old or obsolete electronics and electrical goods, we can look into getting them repaired. Another example of that is to refurbish old drones instead of buying new.

By taking up these eco-friendly practices, our communities will become cleaner, more energy-efficient, and much healthier places to live in, alongside other very practical and tangible benefits that everyone will appreciate.

Not convinced? Well, hopefully listing out those benefits in full below will convince you. Read on as we go through all the biggest reasons why going green is the best thing you can do for your community.

A healthier community

Enacting green and eco-friendly practices in your community will have the immediate effect of making it healthier for the individuals who live in it, enabling them to live longer, happier, and more productive lives. This can be considered as the most important benefit, seeing as we can tie so many health conditions and diseases to having an environmentally-negligent lifestyle. By going green, you can avoid these potential risks from taking hold in your community.

For example, recycling and minimizing trash or garbage helps makes your immediate surroundings cleaner and more attractive to look at. This causes disease-carrying pests such as insects and rodents to be driven away from your community, which then results in less people catching those diseases.

Another example is having the vehicles in your community switch to more eco-friendly fuel types will result in cleaner and healthier air, as well as reduce the chances of children and the elderly from getting respiratory diseases. Many companies like popgear use recycled material in their clothing. These and a whole lot more are attainable by going green.

Savings on utility bills and other expenses

One of the main tenets of going green is to be conservative when it comes to the usage of utilities, such as electricity, gas, water, and so on. It goes without saying that using too much of these obviously strains the environment.

For example, the excessive and unnecessary use of electricity when it’s clearly not needed increases the power demand from power plants, which in turn increases the amount of fuel being used to supply that energy. This uses up our remaining fossil fuels at an alarming rate, while also depositing more pollutants into the atmosphere and environment. The same goes for gas and other utilities.

By being smarter and more conscious about using these precious resources in our homes, we can reduce the impact we have on the environment by quite a large degree. It will help ease the strain our environment is currently experiencing in providing us these resources and ensure that they don’t run out as quickly as they would have if we continued being unnecessarily wasteful with our usage.

Besides this, conserving energy and resources also helps us save on our utility bills. Obviously, the less power, water, and gas we use in our day-to-day, the less we’ll be charged when our monthly bills come in. Up to 20% of expanses per household, according to the US Environmental Protection Agency, are saved, especially if we adopt changes such as using solar panels rather than relying on our electrical grid. This is a huge chunk of money no matter how you slice it!

Durable and stronger homes and and structures

Let’s not mince words about it: eco-friendly and environmentally-conscious “green” products are more expensive than the brands that have an easier time fitting into our budget. However, we must consider that the former is also much more durable than the latter, which will inevitably result in a lot of savings in the long run.

This can be seen the most in building construction materials, especially those involved in the building and repair of homes. For example, recycled decking, which is made from recycled plastic and wooden fibers, have been tested to last five times longer than traditional decking.

Bamboo, a self-sustaining perennial grass that can grow up to three feet in 24 hours, is lighter than most building materials and yet has greater compressive strength than brick and concrete. The best part about it is that it grows faster than it can be harvested, meaning that there’s no danger of running out of it anytime soon, no matter how extensively it’s used.

By creating your community’s homes and structures using these eco-friendly materials, you can help save the environment while also ensuring that the homes and shelters will last for as long as they’re needed.

A self-sufficient community

It’s a fact of life that we have to rely on big companies to get us the modern conveniences and essentials we need to get through the day. However, by going green, we can help reduce our reliance on them and become more independent in our lives.

For example, taking the initiative to install solar panels in every home in your community will allow it to become less dependent on the power that companies provide you with electricity. With enough time, your community will be generating enough excess power that the same company will be paying you for that excess. There’s also the fact that if something goes wrong with the power plant, your community won’t be subjected to the same annoying and disruptive blackout that other surrounding neighborhoods will be, as you’ll have enough solar power to last you the entire time.

college-green

Let’s say you’re not quite at that level yet, in terms of going green. How about supporting your local markets rather than your nearby supermarket? By doing so, you ensure that the food-growing sector of your community continues to earn a living while also retaining the ability to keep growing natural and organic produce. Doing so also cuts down on harmful emissions, as you won’t have to travel by car just to get the fresh food you need. Your community retains its independence while helping the environment.

Conclusion

There are many ways to improve one’s community from the inside, with one of the major and more effective ones being able to adopt eco-friendly and environmentally-conscious practices. By doing so, not only does the community benefit hugely in the end in terms of health, sustainability, and independence from big companies, but the environment as well.

How to Contribute in Saving the Environment: 5 Effective Ways

The year 2020 was a great example of how worse things can get when we humans do not stop messing around with the planet. The Amazon fire, Australian bushfires, tsunamis, climate changes, the cyclones across the globe, and the list is never-ending. And trust me, they are just the start of our downfall if we do not stop.

Finally, when the pandemic forced all of us within locked doors, that’s when nature was finally healing itself. But now, when things are getting back to normal, things are only getting worse.

The lockdown definitely hit us with a realization that there isn’t much that you have to do in order to save nature. In fact, the earth heals itself, but only if we let it. Whether you are a student, a working professional, or a homemaker, all of us can contribute to the environment and try to make it a better place. And trust me, it is not much you will have to do.

Below, I’ve compiled 5 things that you can do to make a real and positive impact to save our planet.

How to Contribute in Saving Environment

1. No plastic bags

Right from childhood, we were taught not to use plastic bags but we, as world citizens have never really taken it seriously.

Definitely, plastic bags are easily available, cheap, and quite handy at times. But the thing is, all of this doesn’t cover up for the fact that they are the 3rd biggest ocean polluters and probably one of the hardest things in the world to dispose of.

In fact, there are water animals worldwide choking on plastic only to die. Besides, plastic has so many substitutes easily available. All you need to do is make an effort to not use plastic as much as possible.

2. Plant trees

Can you imagine how quickly the crux of global warming will resolve itself if even half of the world population plant a single tree? Something as basic as planting trees can save us from extreme weather patterns.

planting trees

Planting more trees and vegetation will go a long way in reducing heat in urban settings.

So, without giving a second thought, plant a tree today and you will be done a lot more than what has been asked of you.

3. Don’t waste energy

Most people think that because you have been paying for electricity, you can also waste it. But you fail to understand that there is a limited supply of energy and if you consume it mindlessly, it impacts nature.

Today, we are all surrounded by electronic devices at all times. This is the modern world’s need; you cannot help with that. But you can definitely make it a point to not waste electricity, and turn off the devices when not in use.

Not only will your monthly electricity bill reduce but you will also be contributing to the planet.

Energy-Saving Tips for Small Businesses

4. Conscious consumption of water

While you have your tap water constantly dripping, there are parts of the world where people die daily due to dehydration and malnutrition. When you dig deep into the numbers, you will be shocked to know how much water is wasted, every day.

This needs to change and like it’s said, change begins at home. So, don’t waste water. No more dripping taps and then gradually move to taking 5-minute showers, rather than showering for hours. In fact, something as basic as turning off the tap while brushing can do wonders.

5. Switch to solar energy

Although not everyone reading this will be able to switch to solar energy sources, but for those who can, this can be one of the best decisions you have ever made, both financially, as well as morally.

Solar panels, solar inverters for PV systems, might look like quite a big investment initially but in due time, you will realize how this clean source of energy helps you save a lot of money and even provides relief from long and frequent power cuts. These are the major reasons why you must encourage people to switch to solar energy.

It might not seem as important and urgent as it actually is but honestly, humans are themselves the biggest danger to fellow humans and to this beautiful planet. But if you want, you can alter that!

Energy Potential of Palm Kernel Shells

The Palm Oil industry in Southeast Asia and Africa generates large quantity of biomass wastes whose disposal is a challenging task. Palm kernel shells (or PKS) are the shell fractions left after the nut has been removed after crushing in the Palm Oil mill. Kernel shells are a fibrous material and can be easily handled in bulk directly from the product line to the end use. Large and small shell fractions are mixed with dust-like fractions and small fibres. Moisture content in kernel shells is low compared to other biomass residues with different sources suggesting values between 11% and 13%.

Palm kernel shells contain residues of Palm Oil, which accounts for its slightly higher heating value than average lignocellulosic biomass. Compared to other residues from the industry, it is a good quality biomass fuel with uniform size distribution, easy handling, easy crushing, and limited biological activity due to low moisture content. PKS can be readily co-fired with coal in grate fired -and fluidized bed boilers as well as cement kilns in order to diversify the fuel mix.

The primary use of palm kernel shells is as a boiler fuel supplementing the fibre which is used as primary fuel. In recent years kernel shells are sold as alternative fuel around the world. Besides selling shells in bulk, there are companies that produce fuel briquettes from shells which may include partial carbonisation of the material to improve the combustion characteristics.

As a raw material for fuel briquettes, palm shells are reported to have the same calorific characteristics as coconut shells. The relatively smaller size makes it easier to carbonise for mass production, and its resulting palm shell charcoal can be pressed into a heat efficient biomass briquette.

Palm kernel shells have been traditionally used as solid fuels for steam boilers in palm oil mills across Southeast Asia. The steam generated is used to run turbines for electricity production. These two solid fuels alone are able to generate more than enough energy to meet the energy demands of a palm oil mill. Most palm oil mills in the region are self-sufficient in terms of energy by making use of kernel shells and mesocarp fibers in cogeneration.

In recent years, the demand for palm kernel shells has increased considerably in Europe, Asia-Pacific, China etc resulting in price close to that of coal. Nowadays, cement industries and power producers are increasingly using palm kernel shells to replace coal. In grate-fired boiler systems, fluidized-bed boiler systems and cement kilns, palm kernel shells are an excellent fuel.

Cofiring of PKS yields added value for power plants and cement kilns, because the fuel significantly reduces carbon emissions – this added value can be expressed in the form of renewable energy certificates, carbon credits, etc. However, there is a great scope for introduction of high-efficiency cogeneration systems in the industry which will result in substantial supply of excess power to the public grid and supply of surplus PKS to other nations. Palm kernel shell is already extensively in demand domestically by local industries for meeting process heating requirements, thus creating supply shortages in the market.

Palm oil mills around the world may seize an opportunity to supply electricity for its surrounding plantation areas using palm kernel shells, empty fruit branches and palm oil mill effluent which have not been fully exploited yet. This new business will be beneficial for all parties, increase the profitability and sustainability for palm oil industry, reduce greenhouse gas emissions and increase the electrification ratio in surrounding plantation regions.

Salient Features of Sugar Industry in Mauritius

Sugar industry has always occupied a prominent position in the Mauritian economy since the introduction of sugarcane around three centuries ago. Mauritius has been a world pioneer in establishing sales of bagasse-based energy to the public grid, and is currently viewed as a model for other sugarcane producing countries, especially the developing ones.

Sugar factories in Mauritius produce about 600,000 tons of sugar from around 5.8 million tons of sugarcane which is cultivated on an agricultural area of about 72,000 hectares. Of the total sugarcane production, around 35 percent is contributed by nearly 30,000 small growers. There are more than 11 sugar factories presently operating in Mauritius having crushing capacities ranging from 75 to 310 tons cane per hour.

During the sugar extraction process, about 1.8 million tons of Bagasse is produced as a by-product, or about one third of the sugarcane weight. Traditionally, 50 percent of the dry matter is harvested as cane stalk to recover the sugar with the fibrous fraction, i.e. Bagasse being burned to power the process in cogeneration plant. Most factories in Mauritius have been upgraded and now export electricity to the grid during crop season, with some using coal to extend production during the intercrop season.

Surplus electricity is generated in almost all the sugar mills. The total installed capacity within the sugar industry is 243 MW out of which 140 MW is from firm power producers. Around 1.6 – 1.8 million tons of bagasse (wet basis) is generated on an annually renewable basis and an average of around 60 kWh per ton sugarcane is generated for the grid throughout the island.

The surplus exportable electricity in Mauritian power plants has been based on a fibre content ranging from 13- 16% of sugarcane, 48% moisture content in Bagasse, process steam consumption of 350–450 kg steam per ton sugarcane and a power consumption of 27-32 kWh per ton sugarcane.

In Mauritius, the sugarcane industry is gradually increasing its competitiveness in electricity generation. It has revamped its boiler houses by installing high pressure boilers and condensing extraction steam turbine. All the power plants are privately owned, and the programme has been a landmark to show how all the stakeholders (government, corporate and small planters) can co-operate. The approach is being recommended to other sugarcane producing countries worldwide to harness the untapped renewable energy potential of biomass wastes from the sugar industry.
