5 Ways Solar Energy Positively Impacts The Environment

Solar energy is one of the most eco-friendly power sources out there. And because of the environmental benefits of solar energy, an increasing number of homeowners and business owners are having solar panels mounted on their properties.

As a green alternative, solar power doesn’t only help reduce power costs but also provides numerous benefits to the natural surroundings. Below you’ll find just a few of solar energy’s most notable impacts on the planet.

solar-energy-diy

 

1. Promotes Water Conservation

Water is an essential natural resource, and if people continue to use it unabatedly, it may run out sooner rather than later. Traditional power generation and transmission processes use significant amounts of water to cool generators and refine and transport fuel through pipes. The same is true whether the facility uses natural gas, nuclear power, or coal power to meet massive electricity demand.

Solar energy, however, doesn’t require water to produce electricity, so it doesn’t further strain water resources. Residential solar panels maintenance works only require periodic rinses and removal of debris and other types of obstruction. In addition, it doesn’t give off wastewater, so it doesn’t contribute to water pollution.

2. Reduces Greenhouse Gases And Carbon Emissions

Most of the energy we use on the planet is produced from burning fossil fuels, which release carbon dioxide. This chemical compound generates heat once released into the atmosphere, that’s why it’s called a greenhouse gas. It’s said that carbon dioxide stays in the atmosphere for more than a thousand years, worsening global warming and negatively impacting the weather systems.

With solar panels meeting residential and commercial electrical needs, fossil fuels don’t have to be burned to make appliances and other power-hungry devices work. Making your home more self-sufficient by mounting solar panels on your roof isn’t only a way to reduce your electricity expenses but a planet-saving measure as well since it relies on a stable and renewable energy source.

3. Avoids Strain On Earth’s Non-renewable Resources

The majority of the world’s current power sources, such as natural gas, oil, and coal, aren’t infinite like the rest of the Earth’s natural resources. As the population continues to grow, so are the demands for those assets. This imbalance continues to strain the Earth’s finite resources, such as fossil fuel. In the face of fast-depleting natural reserves, humans should tap other means of renewable energy sources and minimize their use of the current supply available.

Solar Energy Guide for Students

Switching to solar energy is one great way to preserve the planet’s power resources and lower the demand for them. The sun is nature’s main energy reservoir. It’s said to generate about 173,000 terawatts of solar energy per second. Comparatively, the world’s electricity consumption for 2018 was pegged at 23,398 terawatt-hours. Best of all, solar energy is accessible as long as the sun’s still shining.

4. Helps Slow Down Climate Change

When released into the atmosphere, dangerous emissions from burning fossil fuels damage the environment. What’s more, they can contribute to global warming and extremely erratic climate patterns.

Methane, carbon dioxide, sulfur dioxide, and nitrous oxide can amplify the greenhouse effect. Under normal circumstances, the greenhouse effect is a natural process of warming the earth, making it suitable for life. Unfortunately, processing fossil fuels to generate energy has led to abnormally warmer temperatures at unprecedented rates. As a result, the planet has experienced highly dramatic weather disturbances, including unpredictable atmospheric conditions, violent storms, extreme flooding, and severe drought.

Solar panels produce electricity without emitting dangerous chemicals or toxic gases. As more homes and buildings are switching to the use of solar panels, the current power generation practices are expected to become more environment-friendly. With solar energy, you don’t need to burn fuel and exacerbate the greenhouse effect.

5. Minimizes Air Pollution

Besides the environmentally harmful carbon dioxide, burning fossil fuels can generate other hazardous gases such as methane and sulfur dioxide. These toxic chemicals are released into the air and decrease air quality.

air-pollution-repurcussions

Such gases can endanger people’s health and well-being. Various health problems are linked to long-term exposure to air pollution. These include lung cancer, asthma attacks, allergies, lung diseases, chronic bronchitis, pneumonia, chronic obstructive pulmonary disease (COPD), and headaches, to name a few. Inversely, you won’t have any of those problems with solar energy since it doesn’t produce toxic emissions that harm people and the environment.

Wrap Up

Energy use is essential for human existence. But common power generation methods, for the most part, have proven to be detrimental to the planet and human beings. Access to sustainable and eco-friendly energy sources should be a priority for everyone, and you can do your part by harnessing solar energy for your own power requirements.

Benefits of Sourcing Energy Locally

Numerous businesses nowadays maintain a supply chain globally. However, it is important to note that sourcing locally has numerous benefits to the company you are sourcing from as well as to you as a customer. Especially when it comes to sourcing energy, it is extremely beneficial for an individual to source energy locally. 

There was a time when the consumers of energy had no choice but to use the power supplied to their homes by the government and the generalized power suppliers. The disadvantage many individuals faced due to this was the often shortage of energy and the fluctuating voltage that was a result of long power cables and ill-maintained power lines.

However, with the power supply being localized, it is now much more efficient to receive power from a company you can trust locally and can benefit from investing in the company as well. 

energy-company

When power is sourced from a local company, you are investing in a business that operates in your area. This means that you are helping improve the local economy and increasing its economic value as well. This also means that if there is more than one electrical company providing energy to your area, you will be promoting healthy competition between the energy companies and encouraging those companies to offer you competitive pricing.

We often fail to realize how much utilities can take away from our monthly income, and by being offered a good price for electricity which you consume in your household, you are, in turn, improving your monthly budget

Another great benefit of sourcing energy locally is the fact that they might offer you to buy bulk energy from them or allow you to sign a contract according to the requirements of your household. Private companies often have various packages that they offer their clients, and these packages can include various amounts of electricity units that are based upon the history of consumption of the clients. These packages are often offered at a lower price than general power usage, and therefore if an individual is buying a package, they can benefit from it greatly.

However, it is important to know and predict your consumption requirements accurately as any extra power that you use apart from the package can cost you extra, or any units that go unused in your package might not be redeemable in the next cycle. 

In conclusion, sourcing energy locally can be beneficial for not only yourself but the energy provider as well as the community you reside in. It is also a good idea to conduct adequate research before investing or drawing up contracts with any company as after a contract has been made; you will become bound to the contract. Knowing your requirements and knowing that you can trust the company you are buying from are two extremely important factors.

Solar panels are becoming more accessible, for homeowners and businesses

The Philippines has hot and humid weather, which means households always require air conditioning. Thanks to the introduction of solar air conditioning, many homeowners can reduce their utility bills.

Some of the factors that will drive growth in the solar energy sector are the growing population, as well as the Philippines’ rapid economic development. When the Philippines succeeds in replacing diesel generators in most islands with solar energy, there will be a significant reduction in power outages.

Solar energy and other renewable energy sources will guarantee grid stability throughout the Philippines. Here are the four main trends in solar energy in the Philippines.

1. Accessibility for Private Households

A couple of years back, utility-scale solar was difficult to achieve due to the market’s regulatory changes. The price competition was too high, and only the largest capitalized developers could compete.

However, this is set to change because the new generation of renewable energy can now be distributed to private households. This ensures that each household can install a solar-powered air conditioner to reduce utility costs.

It is a huge win for homeowners and business people because they can now have more control over their energy consumption. Photovoltaic panels can be installed on the roofs of homes, apartment buildings, as well as business establishments.

This means that business owners can generate as much energy as they desire and even sell residual to energy supplies near them.

2. Significant Growth of Solar PV

The production cost of solar energy is expected to fall significantly between 2020 and 2025. As a result, solar will take first place for the cheapest source of energy in the Philippines.

The growth of photovoltaic systems in the Philippines will provide an immediate and more permanent solution to the country’s energy needs. The market is already registering a significant fall in the costs of photovoltaic cells.

Many households are jumping on this bandwagon and taking advantage of the affordability of solar power equipment. As a household in the Philippines, you greatly benefit from purchasing a solar air conditioner.

Residents are also adopting small-scale solar photovoltaic systems because the declined cost of PV technology makes financial sense.

3. Increased Grid Parity

The Philippines has a huge population, and without alternative sources of energy, the grid easily gets unstable. However, due to the introduction of renewable sources of energy like solar and wind, we can see a future where grid parity is guaranteed.

Since more private households can now depend on solar energy for their electricity needs, grid parity has steadily increased. Most households today use solar air conditioner to maintain a comfortable indoor environment. This is a highly cost-effective solution because solar energy is steadily getting cheaper than traditional energy sources.

solar-AC

Not to mention that the overall cost of electricity from the gird is decreasing as well. This can be attributed to the contribution of solar PV. Technological advancements are ensuring manufacturers can produce solar panels with higher solar PV module efficiency.

This means that you can install a solar hybrid air conditioner at home without worrying about the running cost.

4. Storage

There are plans underway to develop solar-storage microgrids in the Philippines. When this plan succeeds, solar energy will play a huge role in improving environmental health, human health, as well as people’s quality of life.

This will be a huge step towards achieving Philippine’s national climate change, greenhouse gas emissions reduction and renewable energy goals. Solar energy production allows the Philippines to reduce its reliance on fuel. The transition to low-carbon energy sources like wind and solar opens up economic development opportunities from a climate perspective.

It is essential to pair solar systems with solar-storage because this boosts the positive impact solar energy has on the economy.

During spring and summer months, the Philippines experiences great solar generation. However, without a storage solution for solar energy, this energy cannot be saved for later. Storage prices are still very high, not only in Asia as a whole but the world over. There are already hybrid solar storage projects in place, but they’re nothing close to bulk solar storage.

One thing is certain though, the prices keep coming down, and more and more solar farms are springing up. Soon enough, the Philippines will be in a position to store solar energy and eliminate over-reliance on fuels.

Conclusion

Harnessing solar energy has ensured that many households in the Philippines can make it through hot and humid days. Solar air conditioners allow homeowners to achieve a comfortable indoor environment without digging too deep into their pockets. These latest trends show that things are only getting better. We can see a future where solar energy is the main source of electricity in the Philippines.

Things You Should Know About the Uses of Hydrogen

Hydrogen will be one of the critical assets in the energy stream in the coming decades for the sustainable development of society. The abundant availability of hydrogen and its application in electricity production using fuel cells without any harmful emissions makes it distinct. It can be produced from renewable and sustainable resources, thus promising an eco-friendly solution for the energy transition in the coming years.

Currently, hydrogen production using the electrolysis of water is most preferred. However, hydrogen production can vary in the range of sectors. Hydrogen can be used in electricity production, biomass, solar and wind power application.

applications of hydrogen gas

Despite its advantages, two significant issues hinder its commercialisation and generalisation as an efficient fuel, and energy transition toward zero-emission and fossil-free energy solutions. The first is hydrogen is an energy vector, which means hydrogen needs to be produced before its use and eventually lead to energy consumption in hydrogen synthesis. The second is the low volumetric energy density of hydrogen, which leads to hydrogen storage and transportation issues because of its lowest volumetric energy density (0.01079 MJ/L)

Researchers have suggested several solutions to attempt to increase this value:

  • compression in gas cylinders;
  • liquefaction in cryogenic tanks;
  • storage in metal-hydride alloys;
  • adsorption onto large specific surface area-materials
  • chemical storage in covalent and ionic compounds (viz. formic acid, borohydride, ammonia)

Applications of Hydrogen

The hydrogen applications are in the food industry to turn unsaturated fats and oils present in vegetable oils, butter into a saturated state. In the metal forming industry, atomic hydrogen welding is used as an environmentally sustainable welding process. In the manufacturing industry, hydrogen and nitrogen are used to create a boundary and prevent the oxidation of metals.

The recent advancements in hydrogen applications in the steel manufacturing industry are one of the most significant hydrogen applications for low or zero-emission iron ore conversion.

ecofriendly-manufacturing

The potential use of hydrogen can play a vital role in reducing greenhouse emissions and the global target of achieving a minimal no emission target by 2050. However, the automotive industry is still the largest consumer and most attractive sector in the current scenario. But with the future forecast of reducing hydrogen fuel cost can do wonders with the goal set during Paris Climate Summit.

Hydrogen use in stationary and automotive applications, such as fuel cell vehicles and hydrogen refuelling stations above all, has shown to be hindered by its volumetric energy density – the lowest among all the standard fuels nowadays used. Compression seems to be the most efficient solution to reach high storage levels, thus making hydrogen more common as a renewable and sustainable fuel.

uses of hydrogen

The availability of several hydrogen compression technologies makes the development of new innovative and environmentally-friendly solutions for the use of energy possible, leading to a transition towards a fossil fuel divestment and making a critical contribution to sustainable development

Biomass Gasification Process

Biomass gasification involves burning of biomass in a limited supply of air to give a combustible gas consisting of carbon monoxide, carbon dioxide, hydrogen, methane, water, nitrogen, along with contaminants like small char particles, ash and tars. The gas is cleaned to make it suitable for use in boilers, engines and turbines to produce heat and power (CHP).

Biomass gasification provides a means of deriving more diverse forms of energy from the thermochemical conversion of biomass than conventional combustion. The basic gasification process involves devolatization, combustion and reduction.

biomass-gasification

During devolatization, methane and other hydrocarbons are produced from the biomass by the action of heat which leaves a reactive char.

During combustion, the volatiles and char are partially burned in air or oxygen to generate heat and carbon dioxide. In the reduction phase, carbon dioxide absorbs heat and reacts with the remaining char to produce carbon monoxide (producer gas). The presence of water vapour in a gasifier results in the production of hydrogen as a secondary fuel component.

There are two main types of gasifier that can be used to carry out this conversion, fixed bed gasifiers and fluidized bed gasifiers. The conversion of biomass into a combustible gas involves a two-stage process. The first, which is called pyrolysis, takes place below 600°C, when volatile components contained within the biomass are released. These may include organic compounds, hydrogen, carbon monoxide, tars and water vapour.

Pyrolysis leaves a solid residue called char. In the second stage of the gasification process, this char is reacted with steam or burnt in a restricted quantity of air or oxygen to produce further combustible gas. Depending on the precise design of gasifier chosen, the product gas may have a heating value of 6 – 19 MJ/Nm3.

Layout of a Typical Biomass Gasification Plant

The products of gasification are a mixture of carbon monoxide, carbon dioxide, methane, hydrogen and various hydrocarbons, which can then be used directly in gas turbines, and boilers, or used as precursors for synthesising a wide range of other chemicals.

In addition there are a number of methods that can be used to produce higher quality product gases, including indirect heating, oxygen blowing, and pressurisation. After appropriate treatment, the resulting gases can be burned directly for cooking or heat supply, or used in secondary conversion devices, such as internal combustion engines or gas turbines, for producing electricity or shaft power (where it also has the potential for CHP applications).

Everything You Should Know About MSW-to-Energy

You know the saying: One person’s trash is another’s treasure. When it comes to recovering energy from municipal solid waste — commonly called garbage or trash— that treasure can be especially useful. Instead of taking up space in a landfill, we can process our trash to produce energy to power our homes, businesses and public buildings.

In 2015, the United States got about 14 billion kilowatt-hours of electricity from burning municipal solid waste, or MSW. Seventy-one waste-to-energy plants and four additional power plants burned around 29 million tons of MSW in the U.S. that year. However, just 13 percent of the country’s waste becomes energy. Around 35 percent is recycled or composted, and the rest ends up in landfills.

Recovering Energy Through Incineration

The predominant technology for MSW-to-energy plants is incineration, which involves burning the trash at high temperatures. Similarly to how some facilities use coal or natural gas as fuel sources, power plants can also burn MSW as fuel to heat water, which creates steam, turns a turbine and produces electricity.

Several methods and technologies can play a role in burning trash to create electricity. The most common type of incineration plant is what’s called a mass-burn facility. These units burn the trash in one large chamber. The facility might sort the MSW before sending it to the combustion chamber to remove non-combustible materials and recyclables.

These mass-burn incineration systems use excess air to facilitate mixing, and ensure air gets to all the waste. Many of these units also burn the fuel on a sloped, moving grate to mix the waste even further. These steps are vital because solid waste is inconsistent, and its content varies. Some facilities also shred the MSW before moving it to the combustion chamber.

Gasification Plants

Another method for converting trash into electricity is gasification. This type of waste-to-energy plant doesn’t burn MSW directly, but instead uses it as feedstock for reactions that produce a fuel gas known as synthesis gas, or syngas. This gas typically contains carbon monoxide, carbon dioxide, methane, hydrogen and water vapor.

Approaches to gasification vary, but typically include high temperatures, high-pressure environments, very little oxygen and shredding MSW before the process begins. Common MSW gasification methods include:

  • Pyrolysis, which involves little to no oxygen, partial pressure and temperatures between approximately 600 and 800 degrees Celsius.
  • Air-fed systems, which use air instead of pure oxygen and temperatures between 800 and 1,800 degrees Celsius.
  • Plasma or plasma arc gasification, which uses plasma torches to increase temperatures to 2,000 to 2,800 degrees Celsius.

Syngas can be burned to create electricity, but it can also be a component in the production of transportation fuels, fertilizers and chemicals. Proponents of gasification report that it is a more efficient waste-to-energy method than incineration, and can produce around 1,000 kilowatt-hours of electricity from one ton of MSW. Incineration, on average, produces 550 kilowatt-hours.

Challenges of MSW-to-Energy

Turning trash into energy seems like an ideal solution. We have a lot of trash to deal with, and we need to produce energy. MSW-to-energy plants solve both of those problems. However, a relatively small amount of waste becomes energy, especially in the U.S.

This lack may be due largely to the upfront costs of building a waste-to-energy plant. It is much cheaper in the short term to send trash straight to a landfill. Some people believe these energy production processes are just too complicated and expensive. Gasification, especially, has a reputation for being too complex.

Environmental concerns also play a role, since burning waste can release greenhouse gases. Although modern technologies can make burning waste a cleaner process, its proponents still complain it is too dirty.

Despite these challenges, as trash piles up and we continue to look for new sources of energy, waste-to-energy plants may begin to play a more integral role in our energy production and waste management processes. If we handle it responsibly and efficiently, it could become a very viable solution to several of the issues our society faces.
