How the Biofuel Industry is Growing in the US

Biofuels were once forgotten in the United States, mainly when huge petroleum deposits kept fuel prices low.  With the increase in oil prices recently, the biofuel industry in the US is rising significantly.  Experts predict that this green energy efficient industry will continue to grow within the next 7 to 10 years.

The Source of Biofuels

Those who are concerned with the prospect of global warming love the potential use of biofuels. Produced either directly or indirectly from used cooking oil, animal waste and plant materials, biofuels are less costly than other types of fuel.  Already in the national and global market, the trend for this fuel is rising.

Online Reverse Auction Software

Due to the growth of the biofuel industry, online software for energy brokers and energy suppliers is an available market for entrepreneurs.  The software to efficiently sell energy services to purchasers is a must have for suppliers and brokers.  The reverse auction process effectively conducts online business for those in the biofuel industry.

Both regulated and deregulated gas and electricity markets are involved in the reverse auction process in which the buyer and seller roles are reversed.  The buyer is given the option of testing and evaluating multiple pricing parameters to find a good fit.  Commercial, industrial, and manufacturing facilities take advantage of this platform.

Reverse Auction Benefits

Reverse auctions in the biofuel industry have been said to cut costs tremendously.  Although the seller pays a fee to the service provider, the bidding process cuts costs all around for both buyer and seller.  A situation in which both sides win is seen as a huge benefit by all involved.

As a very lucrative market, the biofuel industry benefits from reverse auctions.  Market efficiency is increased, and the process of obtaining the goods and services is enhanced.  Proper software and other technical aspects of the process is essential thus the reason that the online reverse auction software market is critical.  Quality and professional relationships are enhanced rather than compromised as is often the case in other markets.

Biofuel Market Projections and Uses

According to market research, the biofuel industry is expected to reach approximately 218 billion dollars by 2022.  A 4.5% growth is expected by 2022 as well.  Investors see these projections as an open door of opportunity.  By the year 2025, the increase is predicted to be at approximately 240 billion dollars.

Biofuel is used for other purposes besides first-generation fuel.  It is used in vegetable oil and cosmetics, and it is used to treat Vitamin A deficiency and other health issues. Biofuel is predicted to aid the improvement of economic conditions due to its health benefits and appeal to green energy supporters.  These factors explain the reasons for the projected growth and profit for this industry.

With the continued growth of the biofuel industry, reverse auctions will be a much-needed process.  The efficient software to accompany reverse auctions will keep the market flowing which will further aid the growth of the industry for years to come.

Biogas Sector in India: Perspectives

Biogas is an often overlooked and neglected aspect of renewable energy in India. While solar, wind and hydropower dominate the discussion in the cuntry, they are not the only options available. Biogas is a lesser known but highly important option to foster sustainable development in agriculture-based economies, such as India.

What is Biogas

Briefly speaking, biogas is the production of gaseous fuel, usually methane, by fermentation of organic material. It is an anaerobic process or one that takes place in the absence of oxygen. Technically, the yeast that causes your bread to rise or the alcohol in beer to ferment is a form of biogas. We don’t use it in the same way that we would use other renewable sources, but the idea is similar. Biogas can be used for cooking, lighting, heating, power generation and much more. Infact, biogas is an excellent and effective to promote development of rural and marginalized communities in all developing countries.

This presents a problem, however. The organic matter is putting off a gas, and to use it, we have to turn it into a liquid. This requires work, machinery and manpower. Research is still being done to figure out the most efficient methods to make it work, but there is a great deal of progress that has been made, and the technology is no longer new.

Fossil Fuel Importation

India has a rapidly expanding economy and the population to fit. This has created problems with electricity supplies to expanding areas. Like most countries, India mainly uses fossil fuels. However, as oil prices fluctuate and the country’s demand for oil grows, the supply doesn’t always keep up with the demand. In the past, India has primarily imported oil from the Middle East, specifically Saudi Arabia and Iraq.

Without a steady and sustainable fossil fuels supply, India has looking more seriously into renewable sources they can produce within the country. Biogas is an excellent candidate to meet those requirements and has been used for this goal before.

Biogas in India

There are significant differences between biogas and fossil fuels, but for India, one of the biggest is that you can create biogas at home. It’s pretty tricky to find, dig up and transform crude oil into gas, but biogas doesn’t have the same barriers. In fact, many farmers who those who have gardens or greenhouses could benefit with proper water management and temperature control so that plants can be grown year round, It still takes some learning and investment, but for many people, especially those who live in rural places, it’s doable.

This would be the most beneficial to people in India because it would help ease the strain of delivering reliable energy sources based on fossil fuels, and would allow the country to become more energy independent. Plus, the rural areas are places where the raw materials for biogas will be more available, such animal manure, crop residues and poultry litter. But this isn’t the first time most people there are hearing about it.

Biogas in India has been around for a long time. In the 1970’s the country began a program called the National Biogas and Manure Management Program (NBMMP) to deal with the same problem — a gas shortage. The country did a great deal of research and implemented a wide variety of ideas to help their people become more self-sufficient, regardless of the availability of traditional gasoline and other fossil fuel based products.

The original program was pioneering for its time, but the Chinese quickly followed suit and have been able to top the market in biogas production in relatively little time. Comparatively, India’s production of biogas is quite small. It only produces about 2.07 billion m3/year of biogas, while it’s estimated that it could produce as much as 48 billion m3/year. This means that there are various issues with the current method’s India is using in its biogas production.

Biogas has the potential to rejuvenate India’s agricultural sector

The original planning in the NBMMP involved scientists who tried to create the most efficient biogas generators. This was good, but it slowed people’s abilities to adopt the techniques individually. China, on the other hand, explicitly worked to help their most rural areas create biogas. This allowed the country to spread the development of biogas to the most people with the lowest barriers to its proliferation.

If India can learn from the strategy that China has employed, they may be able to give their biogas production a significant boost which will also help in the rejuvenation of biomass sector in the country. Doing so will require the help and willingness of both the people and the government. Either way, this is an industry with a lot of room for growth.

Biomass Pelletization Process

Biomass pellets are a popular type of biomass fuel, generally made from wood wastes, agricultural biomass, commercial grasses and forestry residues. In addition to savings in transportation and storage, pelletization of biomass facilitates easy and cost effective handling. Dense cubes pellets have the flowability characteristics similar to those of cereal grains. The regular geometry and small size of biomass pellets allow automatic feeding with very fine calibration. High density of pellets also permits compact storage and rational transport over long distance. Pellets are extremely dense and can be produced with a low moisture content that allows them to be burned with very high combustion efficiency.

biomass-pellets

Biomass pelletization is a standard method for the production of high density, solid energy carriers from biomass. Pellets are manufactured in several types and grades as fuels for electric power plants, homes, and other applications. Pellet-making equipment is available at a variety of sizes and scales, which allows manufacture at domestic as well industrial-scale production. Pellets have a cylindrical shape and are about 6-25 mm in diameter and 3-50 mm in length. There are European standards for biomass pellets and raw material classification (EN 14961-1, EN 14961-2 and EN 14961-6) and international ISO standards under development (ISO/DIS 17225-1, ISO/DIS 17225-2 and ISO/DIS 17225-6).

Process Description

The biomass pelletization process consists of multiple steps including raw material pre-treatment, pelletization and post-treatment. The first step in the pelletization process is the preparation of feedstock which includes selecting a feedstock suitable for this process, its filtration, storage and protection. Raw materials used are sawdust, wood shavings, wood wastes, agricultural residues like straw, switchgrass etc. Filtration is done to remove unwanted materials like stone, metal, etc. The feedstock should be stored in such a manner that it is away from impurities and moisture. In cases where there are different types of feedstock, a blending process is used to achieve consistency.

The moisture content in biomass can be considerably high and are usually up to 50% – 60% which should be reduced to 10 to 15%. Rotary drum dryer is the most common equipment used for this purpose. Superheated steam dryers, flash dryers, spouted bed dryers and belt dryers can also be used. Drying increases the efficiency of biomass and it produces almost no smoke on combustion. It should be noted that the feedstock should not be over dried, as a small amount of moisture helps in binding the biomass particles. The drying process is the most energy intensive process and accounts for about 70% of the total energy used in the pelletization process.

Schematic of Pelletization of Woody Biomass

Before feeding biomass to pellet mills, the biomass should be reduced to small particles of the order of not more than 3mm.  If the pellet size is too large or too small, it affects the quality of pellet and in turn increases the energy consumption. Therefore the particles should have proper size and should be consistent. Size reduction is done by grinding using a hammer mill equipped with a screen of size 3.2 to 6.4 mm. If the feedstock is quite large, it goes through a chipper before grinding.

The next and the most important step is pelletization where biomass is compressed against a heated metal plate (known as die) using a roller. The die consists of holes of fixed diameter through which the biomass passes under high pressure. Due to the high pressure, frictional forces increase, leading to a considerable rise in temperature. High temperature causes the lignin and resins present in biomass to soften which acts as a binding agent between the biomass fibers. This way the biomass particles fuse to form pellets.

The rate of production and electrical energy used in the pelletization of biomass  are strongly correlated to the raw material type and processing conditions such as moisture content and feed size. The The average energy required to pelletize biomass is roughly between 16 kWh/t and 49kWh/t. During pelletization, a large fraction of the process energy is used to make the biomass flow into the inlets of the press channels.

Binders or lubricants may be added in some cases to produce higher quality pellets. Binders increase the pellet density and durability. Wood contains natural resins which act as a binder. Similarly, sawdust contains lignin which holds the pellet together. However, agricultural residues do not contain much resins or lignin, and so a stabilizing agent needs to be added in this case. Distillers dry grains or potato starch is some commonly used binders. The use of natural additives depends on biomass composition and the mass proportion between cellulose, hemicelluloses, lignin and inorganics.

Due to the friction generated in the die, excess heat is developed. Thus, the pellets are very soft and hot (about 70 to 90oC). It needs to be cooled and dried before its storage or packaging. The pellets may then be passed through a vibrating screen to remove fine materials. This ensures that the fuel source is clean and dust free.

The pellets are packed into bags using an overhead hopper and a conveyor belt. Pellets are stored in elevated storage bins or ground level silos. The packaging should be such that the pellets are protected from moisture and pollutants. Commercial pellet mills and other pelletizing equipment are widely available across the globe.

4 Tips For Keeping Your Home Energy Prices Low

Heating can be very expensive nowadays and keeping the heat contained within your home can be a challenge. You will see that energy prices manage to hike year after year and it is important to keep the heat contained in a home where there is particularly cold weather outside to assist with your overall energy costs.

energy-monitor-for-home

Ensure efficient heating system

Modern houses normally have a good heating system and there is a lot of regulation around this to ensure that when people are buying new homes, the efficiency has been taken into consideration from the manufacturers. There are websites like myjobquote.co.uk that you can use in order to arrange local boiler engineers to come out and review your current heating systems to ensure they are effective.  They would also offer services such as a boiler power flush if it is required – again supporting the effectiveness of your appliance.

If your boiler or radiators are not working greatly then a boiler service cost quote may be required in order to make sure they get repaired and are working as well as possible. If any of your heating equipment is faulty and not working correctly then you will overcompensate in terms of the heating you put on in the home which would then significantly increase your costs.

Take action on drafts

If there are any potential drafts and air seeping out of the home, then it will affect the warmth of your home and ultimately your energy bill.  Be sure to take action when you recognise any of these problems.

Some common draft points will be doors and windows and are usually pretty noticeable if there is a problem. Nowadays most homes have double glazed windows and secured doors where this shouldn’t be an issue. If your house has a chimney, then this is another potential area for cold air to get in. If not in use you may wish to consider sealing this off in totality.

Set timers for heating

Putting the heating on and off all the time could also be affecting your bills. Consider getting a timer where you can control the heating at intervals that suit you. Clearly, this wouldn’t be suitable all the time and if you are in the home and there is additional heat required then you can “boost” to allow more heat to come out for longer.

Setting the timers will assist with being disciplined on a routine and you can know pretty accurately what it is that you will be spending every month.

Energy monitors

Energy monitors are becoming really popular nowadays with the users able to then see immediately how much energy they are consuming.  Most energy providers now give this service where you can get one of these appliances installed (generally for free or a very little cost).

The government is also doing a lot more to try and encourage every household to have one of these to help with the energy cost hike challenges.

Sustainable Environment in Singapore: An Attraction for Businesses and Investors

In addition to a robust economy, Singapore’s sustainable environment is another leading factor that has attracted numerous investors. Most cities in the world have failed to address environmental issues brought about by urbanization. Towns or urban areas cover over 2% of the Earth’s surface; they are responsible for about 80% of the greenhouse gases emitted while using up almost 75%  of nature’s resources.

sustainable-Singapore

However, a host of countries in Southeast Asia are leading the way to change this contrary notion about cities and urban regions. Research conducted by several world-leading environmental bodies and institutions determined that Singapore is indeed one of the most environmentally sustainable nations.

Singapore’s first prime minister kickstarted the dream of making Singapore a green city. His main agenda was to make Singapore stand out from the rest of the Asian countries and also attract investors from all over the world. The first step undertaken to achieve this dream was the eradication of the houseboats and overcrowded slums along the banks of Singapore River.

Incorporation services Singapore are offering entrepreneurs moving to Singapore a platform to incorporate their businesses in Singapore. This allows them to run their firms within the stipulated terms while also receive the government’s backing.

On the world’s Environmental Performance Ranking, Yale University and the U.N place Singapore at seventeenth globally and first position in Asia. Contrary to popular belief, Singapore’s efforts and strict green technology guidelines, which were set and backed up by the government, helped in making it an eco-friendly city.  

So how exactly does Singapore afford to provide suitable surroundings perfect for its citizens and also attract investors and entrepreneurs from overseas?

Government Support

As discussed before, adoption of green technology is one of the leading things that has made Singapore an eco-friendly city. Singapore has been able to morph into a modernized city-state without having a negative impact on nature.

The Singapore government’s Cleantech division, which is a subsidiary of the board tasked with economic growth, has offered continued support to companies in the clean technology business. This has led to the business sector growing tremendously in areas such as renewable energy, water conservation, green buildings, etc.

Growing ICT Center

Companies such as Hewlett Packard (HP) and International Business Machines Corporation have partnered with the Ministry of Environment and Water Resources. The main idea behind these partnerships is to ensure that Singapore’s ICT industry thrives. HP, for example, has been tasked with designing and manufacturing energy efficient systems that will cut power costs while still providing a working platform for businesses.

There is no shortage of green spaces in Singapore

Low Energy Costs and Environmental Remedies

Accommodating over 7000 companies from different nations across the globe is no mean feat. As such, Singapore’s government and other agencies know that a green environment is not the only requirement to attract more investors.

Through an alliance known as the Singapore Sustainability Alliance, an umbrella consisting of government groups, non-governmental organizations, and teaching institutions, Singapore has been able to come up with policies that create a sustainable environment. Other than this, the alliance has overseen the adoption of systems that include proper water use, renewable energy, energy efficiency, waste management, etc. which have significantly improved business growth.  

Insights into 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.

MSW-to-Energy

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 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 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.

Typical layout of MSW-to-Energy Plant

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.

Home Renovation Can Improve Energy Efficiency

There is almost nothing more satisfying than a clean, fresh, and sustainable home. You may think that renovating your home is a hassle, not to mention expensive, but there are plenty of small changes that can make a home really feel like it’s yours. Something as simple as a new garage door, or a small solar panel can bring personality and life to your home while saving energy and giving you a boost of pride for your house.

Doors and Windows

When thinking about renovating your house, you probably think, new basement, new roofing, and much more expensive and time consuming projects. But do not write off home improvement just yet! There are plenty of small changes that can make a huge difference to the style of your home and even boost its overall value.

Keeping your home well insulated is a wonderful option.

Doors and windows play a huge part in energy efficiency as air enters and escapes your home. This makes these options a great place to start as they add a personal flair to your home’s look as well as being environmentally friendly. Below is a short list of these renovations you may not have thought about.

Garage Doors

When thinking about the outdoor curb appeal of your home, an often overlooked detail is the garage. This may seem silly but just think about how much visual space your garage door or doors take up.

A new or refurbished garage door can not only up the style and personality of your home, but can make your home more energy efficient and secure. And with companies like CSSGarageDoors there are so many styles to choose from.

Front Door

A unique front door also helps your house stand out and adds your own personal touch to your home. Keep in mind the style of your garage doors and make sure your other doors do not clash. Replacing old front doors can also save you money and energy, as air often escapes from unseen cracks in old doors and windows.

There are hundreds of style choices to choose from, and many energy efficient sustainable options too. Not only will this give your home an instant personality boost, it will raise the value of your home significantly.

Windows

While this one may be a little more on the pricey side of renovations, it is yet another example of boosting your homes personality, value, and efficiency. Not only can you choose from styles of windows, you can choose how you want the glass and frames to make them custom just for you and your home.

New windows will save you money on heating and air and some even keep out the noises of busy streets or noisy neighbors. Depending on the climate and place you live, these replacements could be a life saver. Lowes has an excellent selection of beautiful window and door replacements.

Energy Efficiency and Sustainability

While improving the overall look of your home can give you a sense of personal pride in your home, less visible but sustainable options can give you comfort and help the planet. If you want to live more sustainably but do not have the funds to build a whole new eco-friendly home, there are small changes that can boost your home’s energy efficiency and sustainability. Below is a short list of options to improve your home from the inside out.

Tankless Water Heaters

Water heaters are probably something you do not often think about. However, that tank that sits in your garage or basement is constantly using energy. Even when you are not using your hot water, the tank is busy working away using energy and costing you money. Switching to a tankless or on-demand water heater means that it will only be using energy when you need it.

Solar Panels

Solar panels are becoming better and better, and adding one to your homes exterior no longer seems like a dream. While there is a lot to consider before installing solar panels, they can be an amazing way to reduce energy and a great investment.

Although solar panels can last for up to 30 years, you do not need to be afraid of wasting money when you move as they can increase the value of your home significantly. You can also get a sizeable tax return for installing solar panels, so it is a great option to look at for sustainable living.

Tips to Make Your Bathroom More Energy-Efficient

The recent intense and repeated heat-waves suggest that we stop taking our environment for granted. In fact, it is now high time for us to ‘man up’ and pay attention to our environmental responsibilities so that our planet can regain its much-needed equilibrium. Today we live in an otherwise environmentally conscious era. So it is imperative that we all pay due attention to our overall energy usage.

There is sound reasoning behind this strategy. In fact, essentially lowering our overall use of energy means that we can reduce our ‘environmental footprint,’ that is, the overall impact of our energy usage on not just the environment alone, but also lessen the burden on our wallets as well, great deals on https://www.bellabathrooms.co.uk/

It is pertinent to note that the bathroom is one of the single most wasteful places in the house, in terms of prolonged energy usage.

When you take those long, warm sand luxuries showers, Flush the commode all too frequently or have plenty of dripping faucets, then all of these activities conspire and contribute towards putting a substantial dent in your wallet in the form of hefty bills, that just keep racking up at the far end of the month.

Now, the question arises how precisely, can we go about substantially reducing this almost inevitable use of such energy?

Making a few small changes is not very difficult but doing so can help you save a ton in terms of energy-related bills. Here is how:

Changing the shower head as well as sink mixer

Changing to a high-efficiency showerhead and sink mixer and faucet combo can effectively slice your shower and shave water consumption by half. As a matter of fact, newer models of faucets and showerheads can now easily provide the same sense of luxurious ‘feel’ of various other models while simultaneously using considerably less energy, in the bargain.

With the help of these models, you will not only be able to enjoy the same showers you had before but will be able to tell the difference only and only when you get your water bill at the end of the month!

Saving electricity with energy savers and solar panels

Many, if not most people are completely unaware of the fact that those extra bright lights above their sinks are actually power guzzlers, in every sense of the term. This is why it would be prudent to figure out if there are actually energy efficient light bulbs in your bathroom, or not.

The thing is that most people use at least 4 to 5 light bulbs in their bathrooms to make the place nice and bright. However, not using energy savers can be a huge waste of energy. This wastage can efficiently be curbed with energy efficient bulbs as well. It will be well worth it, since it is possible to curb energy usage by as much as 80% when using energy savers, in lieu of ordinary bulbs as such. If you want to go further into the picture, then you can also opt for solar panels to run your bathroom lights.

Curtail these really bad energies wasting habits

From using a hair dryer to an electric razor and trimmer combo, the odds are that the average house owner probably uses a lot of electrical appliances in the washroom on a more or less daily basis. If such is the case with you as well, then you should always unplug every device once you are done using it to see the huge amount of energy savings on the next monthly bill that you receive.

A rule of thumb: Even if the appliance has been powered off, it will nevertheless still continue to consume minute amounts of energy. This is why it is standard best practice to unplug the devices from the mains outlets to ensure that there is no additional drain on your power resources.

Always turn the faucet off whenever you can

One of the most harmful things you can do while being in the washroom is to keep the water running at full blast while you wash your hands and face or brush your teeth. The prudent thing to do is to turn off the water tap when you do not need all that water. Remember, should you leave the water running even as you brush your teeth, then you will almost certainly end up using between an estimated 4 to 5 gallons of water, every time you do so.

Now, just imagine that you repeat this behavior at least three times a day each and every time, you either wash your hand and face or brush your teeth. That is an estimated 12 to 15 gallons of precious water wasted just because you leave the faucet open.

Being environmentally responsible means being completely conscious of all of your bathroom related energy usage, so that you know when you should turn off the tap and save your water supply (and decrease your water bills as well, in the bargain).

Get into the shower when you open the faucet

If you are guilty of opening the shower and letting the water flow while you prepare breakfast or try to find your socks, when going for work, then this is something that you should really take care of, post haste. Apart from that, you can also get a smart meter installed so as to keep track of your energy usage.

Conclusion

In the light of the above, we can safely conclude that taking care of these small issues can lead to great benefits not just for the environment, but also decrease your power bill burden as well. So whether you are renovating your home or moving to a new house, these ideas can help you make your bathrooms more energy efficient.

A Blackout, Big Oil, and Wind Energy

During the first quarter of 2017, workers installed a wind turbine somewhere in the US every 2.4 hours. Wind provided 5.6% of all the electricity produced in the US in 2016. That’s more than double the amount of wind power in 2010. The whole world is seeing similar growth.  The wind industry isn’t without controversy. Critics blame it for the scope of a blackout in Australia. On the other hand, international oil companies have begun to build off-shore wind farms.

Critics’ case against wind energy

According to its critics, wind power is unreliable. The wind doesn’t blow all the time. It doesn’t blow on any predictable pattern. Wind turbines require some minimum wind speed for them to work at all. And if the wind is too strong, they can’t operate safely and must shut down.

Wind can cross one or the other of these thresholds multiple times a day. They operate at full capacity for only a few hours a year. So the theoretical capacity of a wind farm greatly exceeds its actual output.

The times turbines can generate electricity do not coincide with rising and falling demand for electricity. This variability creates problems for stabilizing the grid. Critics further claim that the wind industry can’t operate without massive government subsidies.

Wind power and South Australia blackout of 2016?

South Australia depends on wind energy for about 40% of its electricity. It suffered seven tornadoes on September 28, 2016. Two of them, with winds almost as fast as Hurricane Katrina, destroyed twenty towers that held three different transmission lines. Nine wind farms shut down.  Within minutes, the entire state suffered a massive blackout.

What contributed the most to the blackout? South Australia’s high dependence on wind power? The weather? Or something else?

Renewable energy skeptics quickly claimed the blackout justified their position. The wind farms simply failed to provide enough electricity in the emergency. Wind and solar energy, they say, are inherently unreliable. South Australia’s heavy reliance demonstrates an irresponsible policy based on ideology more than technological reality.

Certainly, the weather would have caused a disturbance in electrical service no matter what source of electricity. People near the downed transmission lines could not have avoided loss of power. But prompt action by grid operators makes it possible to bypass problem areas and limit the extent of the outage.

On closer examination, however, the correct answer to the multiple-choice question above is C: something else.

Wind turbines have “low voltage ride through” settings to keep operating for brief periods when voltage dips below the threshold at which they can operate correctly. If low-voltage conditions occur too frequently, the turbines have a protection mechanism that turns them off.

  • Ten wind farms experienced between three and six low-voltage events within two minutes. But the turbines were operating on factory settings. No one performed any testing to determine good settings under local conditions.
  • The agency that regulates the Australian electricity market knew nothing about the protection feature. It blamed the wind farms, but surely someone on staff should have been familiar with the default operation of the turbines. After all, the agency approved purchase and installation of the turbines. It had all the documentation.
  • Two gas generating plants that should have supplied backup power failed to come online.

The weather caused a problem that became a crisis not because of technical limitations of renewable energy, but because of too many different organizations’ incompetence.

If the wind is too strong, wind turbines can’t operate safely and must shut down.

One homeowner in South Australia didn’t suffer from the outage. He didn’t even know about the blackout till he saw it on the news. He had to test the accuracy of the news reports by opening his oven and noting that the light didn’t come on.

It turns out he had installed solar panels just a few weeks earlier. And since power outages in his part of South Australia occur almost every month, he decided to install a Tesla Powerwall as well.

He can’t use it to power his entire house, but it takes care of the lights and the television. It stores enough electricity for 10 hours of off-grid power.

International oil companies have not joined the chorus of wind-industry skeptics. Several of them, including Royal Dutch Shell, have begun to invest heavily in off-shore wind farms. Especially in the North Sea. Oil production there has steadily declined for about 15 years.

Exploring for new oil fields has become too risky and expensive. These oil companies have decided that investing in wind energy helps their cash flow and makes it more predictable.

Oil companies have more expertise in working on offshore platforms than do companies that specialize in wind energy. Instead of building a foundation for turbines on the ocean floor, at least one oil company has begun to explore how to mount them on floating platforms.

Traditional wind energy firms have been operating turbines in the North Sea for years, but the oil companies have begun to outbid them. Their off-shore expertise has helped them drive down their costs.

So far, American oil companies have shown less interest in wind farms. If they decide they’re in the oil business, they will eventually lose market share to renewable energy companies. If they decide they’re in the energy business, they’ll have to start investing in renewable energy. And if any decide to invest heavily in solar power besides or instead of wind, they will still be following the lead of Total, a French oil company.

For that matter, the coal business is dying. Perhaps some of them will have enough sense to invest in renewables to improve their cash flow.

Renewable Energy Production in Australia: The Plan to Reduce Coal Use

Recently there has been a lot of talk in how a country can improve their ecological footstep. One way of doing so is definitely changing the way the respective country produces its energy. Australia has recently been headlining the news in regard to the renewable energy situation. Australia’s energy production is looking towards a new future with a specific aim on solar and wind power.

If Australia plans on keeping its water resource at a steady level, it has got to go from its use of coal to renewable sources. Thanks to its abundance in both solar and wind energy, Australia has quite the advantage when it comes to green energy production possibilities.

Unfortunately though due to their geographic position, the water supply is limited for the country. So much so, that the coal industry was taking a toll on the water supply due to the large quantities of water needed when producing energy from coal. As a result, moving over to wind and solar energy fueled productions is a viable option seeing how both respective energy productions do not require water.

The news that Australia was listed as a “water-stressed company” was released by the World Resource Institute; a non-profit organization based in Washington D.C. Moreover, on this past May 13th The Sydney Morning Herald also wrote that 73% of Australia’s electricity needs were met by the use of coal. In respect to these findings and Australia’s continuous growth, it is imperative that new resources are used for energy production.

Australia has been making headlines in renewable energy sector.

Fortunately, Australia’s geography is a big resource as well when it comes to studying the possibilities of implementing the new energy productions. It was in fact calculated that the dimensions of the solar power farm needed to meet the country’s demands would result in occupying only 0.1% of Australia’s total land mass; I think we can all agree on the fact that that land could be spared for a solar farm.

And on that note, the government is taking the matter seriously, and has called upon everybody to try and better the situation. The incentives call upon small businesses and households as well by reminding them that there are the possibilities of installing their own solar panels, heat pumps, solar water heaters, and more.

Thanks to the various incentives, the Green Energy Council has stated that there is a lot of activity in the sector, including at least 58 different projects focused on implementing the renewable energy sources. As a consequence of these projects, the council has also stated that there would be an income of $10 billion in investments, 6,141 new jobs, and 5,482 megawatts of renewable energy capacity. Definitely great numbers to look forward to!
