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.
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.
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.
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.
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.
Texans are all about doing things in a big way and that includes saving and making money. One of the newest ways that residents across Texas are padding their wallets is by adding solar arrays to their homes. Most people know that you can save money with solar but aren’t aware that you can actually make money too.
The most popular trend in home design today is adding eco-friendly features. From full Net Zero homes to adding Energy Star appliances, homeowners are looking for ways to adopt a more eco-friendly lifestyle. Carbon footprint reduction has become a serious issue for people around the world.
One of the biggest roadblocks of adding solar to your home is the initial set up cost. Putting up solar panels and setting up a full battery and conversion system can be expensive. But, it’s worth the cost when you take part in a solar panels buyback scheme that will have the power companies paying you instead of you paying out to them.
We have put together a list of some of the ways that you can make money by adding solar to your home in Texas and around the country.
Lower Your Bills
The amount of money that you can save on your energy bills is largely dependent on the size of the solar array you choose to invest in. You can calculate how much solar power you need to run your home using an online app or talk to your provider about how many panels are right for your home.
Once you are set up you will start to see an immediate reduction in the cost to power your home. If you add a large enough array you can eliminate your energy bills altogether, putting money back in your pocket every month.
Raise Property Value
Your home is likely the largest financial investment that you will ever make. With the markets still recovering, it’s important to find ways to increase the value of your home. When you add solar to your home you can expect a 4% increase in your property value. That can be a big chunk for many homeowners and a great way to put money in the bank when it comes time to sell your home.
The only things in life that you can’t avoid are death and taxes. But, wouldn’t it be nice to make a better return during tax season? When you decide to go solar you can get a great tax break at the end of the year.
Up to 25% of your initial set up cost for home solar can be written off on your annual tax return. That’s a huge break for many families and allows you to invest in your solar package with confidence.
For those homeowners that end up collecting more solar energy than they need to power their homes, there are great benefits to signing up for a solar buyback program. This means that any power that you produce in excess of what you need can be sold back to be used by your local grid. This means that instead of sending money out to the energy companies, they will actually start paying you.
Money is a scarce resource. Don’t let monthly bills break your bank while there are numerous things you can do to minimize them. From adding attic insulation to insulating outlets, and installing programmable thermostats, you’ve countless options for reducing your utility bills. Check out the following tips for cutting down your monthly expenses affordably and more effectively. Plus, you will learn everything utility bills.
Incorporate Attic Insulation
Most of the energy people use at their homes goes toward heating or cooling. Research shows that most of this heat escapes to the attic. Most homes lack enough insulation up there to prevent heat from getting out.
Fiberglass insulation is extremely cheap and easy to install. In fact, you can quickly install them on your own. By effectively insulating your home, you could actually save up to 20 percent on your heating, as well as, cooling costs.
But if you can’t install attic insulation yourself, you can always get help online. There are numerous DIY tutorials that can help you through the process.
Install Programmable Thermostats
By installing a programmable thermostat, you’ll be able to save up to 10 percent on your utility bills. Set your unit’s temperature to drop during winter months and raise them during the summer months when you aren’t home.

Thus, it’s possible to set the temperature of your room from your workplace before reaching home. This not only reduces energy costs but also improves the overall efficiency.
Why Utility Bills Keep On Increasing
The dreaded energy bill is coming. It can be annoying. If you are unlucky, it will deflate your bank account. Of course, you can try several measures to control the energy budget. However, things may not work out, especially if you don’t pay close attention to your HVAC system. According to research, the HVAC is responsible for almost half of the energy costs in homes. Thus, if you need to bring these bills down, work on your HVAC system. It’s one of the best starting points. So, if you have been wondering why your monthly bills are steadily increasing, sit back. Here are the top reasons why your energy bills are not going down any time soon.
Age has a big say when it comes to the performance of your HVAC system. An old system tends to be less efficient. This means that it will work more to cool or heat any space. So, if your system has served you for years, expect the bills to continue going up. Similarly, a poorly maintained HVAC system tends to be inefficient. This means that it will consume more energy and pump up energy costs. However, don’t let these factors continue draining your money.
You can install a new HVAC system and drive the bills down. If you have the cash, consider going for a smart system. It’s efficient, convenient, and highly reliable. Also, consider maintaining your system on a regular basis. Consult with your heating and cooling contractor to schedule maintenance. According to experts, it’s advisable to do it twice per year.
The operating costs at a particular time can influence the amount you pay towards offsetting your energy bills. For instance, systems that were developed in the 1990s are less efficient than their modern counterparts. This can be attributed to the emergence of technological advancement. For instance, sensors have made these systems more smart and efficient. Thus, they consume less amount of energy, which plays a key role in bringing the energy bills down. Customers are advised to install the newest HVAC systems to bring the energy bills down.
Features also play a key role when it comes to cutting down energy costs. Modern systems come with sophisticated features that make them more efficient. For instance, the efficiency standards of modern equipment are on an upward trajectory. This means that modern systems have superior performance and efficiency than their older counterparts.
Standard such as SEER, HSPF, as well as Annual Fuel Utilization is important in determining the efficiency of any system. Also, energy features like variable-speed fans, heat exchange technology, as well as variable speed based compressors can make your system more efficient.
The Locality’s Climate
Your local climate can also increase or lower the amount of money you pay towards energy bills. For instance, if you are located in an extremely cold setting, you will need more energy to heat the interiors. Consequently, your energy bills will be higher. On the other hand, those located in extremely hotter environments will spend more money to cool the interiors.
Also, the following additional factors play a key role when it comes to the energy bills of any home.
The thermostat and other control settings in your system
How the unit was installed
Maintenance levels of your system
The level of insulation in any home
Windows, doors, and other openings in your home.
Are you looking for quick ways to reduce your energy bills? Well, there are actually several measures you can undertake to minimize your electricity costs. According to http://www.regionalenergy.ca/alberta-natural-gas-company/, these measures include insulating outlets and switches, installing a programmable thermostat, insulating your water heater, and installing a low-flow showerhead. Doing this will go a long way in reducing your utility bills and saving you junks of money.
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.
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.
The solar energy market in the Philippines has been growing exponentially since 2018. In fact, the Philippines Board of Investments (BOI) had approved eight solar projects that year. The Solar Philippines Commercial Rooftop Projects Inc. oversaw all eight that were equivalent to $1.65 billion.
Even though, as of today, the solar power industry is still on the nascent stage, it is expected to gain massive support from the government moving forward.
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.
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.
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.
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.
On average, small and midsize businesses in the United States use 15 kWh of electricity annually, mostly on lighting, heating, and cooling. These make up 19% of total expenses on an average office building. Energy-saving helps small businesses to increase profits, promote growth, and reduce environmental impacts by lowering carbon dioxide emissions, boosting customer experience and comfort. Here are the top 5 energy-saving tips for small businesses:
1. Conduct regular energy audits
Energy audits involve the hiring of utility data management services to gather, standardize, validate, and interpret utility bill data to enable you to analyze, benchmark, and find opportunities to improve building performance. The energy audits aim at identifying potential changes that can lower energy consumption.
Business energy audits include gas, water, and electricity tariff reviews, consumption analysis and recommendations, expert energy management advice, and contract management.
2. Install a smart thermostat
Smart thermostats, also known as programmable thermostats, are electronic devices that offer you high-level control over your HVAC system operation by providing specific features and settings that help you save significant amounts of energy. They automatically turn the heating and cooling system on and off, depending on your temperature settings.
Thermostats have a set point control that turns down your HVAC when not needed and automatically turns it on before work resumes to ensure an ideal indoor temperature. Besides giving you remote control via mobile phones or online, smart thermostats enable better monitoring of energy usage so you can adjust as needed to avoid wastage or overuse.
3. Use lighting controls and sensors
Lighting controls automatically turn lights on and off as needed to save energy. Occupancy sensors turn on lights immediately; they detect occupants in a space and are ideal in areas that people move in and out of unpredictably. You may also consider dimming controls that match lighting levels with user requirements, saving energy. In addition, you can use zero-power wireless sensors that use the scavenging technique to operate without batteries.
Photosensor controls ensure that outdoor lights don’t run during the day, while timer controls can be programmed to turn outdoor and indoor lights at specific times. Using kinetic energy, they create energy that can power electrical devices. This technology is still evolving, and you may not find as many sensors.
4. Reduce your business’s electronic footprint
Electronics can consume a lot of energy in an office setting. Focusing on electronics energy consumption can help lower energy costs. Consider replacing your desktops with laptops as they use less energy. Remember to power down your electronics when not in use and avoid using screen savers.
You may also consider buying energy-efficient office equipment and avoid energy vampires like monitors to save on energy costs.
5. Consider alternative options
Electricity can be expensive. Shop around for alternatives that can best suit your business. You may consider installing solar panels as they are a cheaper energy source compared to electricity. They also come in handy during power outages.
Alternatively, standby generators are also an efficient power source and are ideal even in extreme weather conditions. They are an efficient long-term energy source that helps lower energy costs.
Small businesses are continually looking for ways to save costs to maximize profits and enhance growth. These energy-saving tips will help you cut costs to increase your profit margins.
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.
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.
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.
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 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.
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).
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.
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:
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.
