What Are The Benefits Of Renewable Energy – A compelling study published today by the United States Department of Energy (DOE) indicates that state-wide standards for renewable energy (RES) help improve public health and the environment, create jobs, and protect consumers. This comprehensive national assessment, the first of its kind, confirms what clean energy advocates have argued for years: the benefits of investing in renewable energy far outweigh the costs.
RES is a market policy that requires electricity suppliers to gradually increase the amount of wind, solar and other renewable energy sources in their energy supply. Currently, 29 states and the District of Columbia have renewable energy policies. For nearly two decades, renewables have been the main driver of renewable energy growth in the United States. As of 2014, state-of-the-art renewable energy resources have driven more than 50 GW of new renewable energy development and are expected to support an additional 67 GW by 2030.
This new analysis, conducted by scientists at the Department of Energy’s National Renewable Energy Laboratory and the Lawrence Berkeley National Laboratory, examines a number of potential benefits and effects of new renewable energy sources designed for state-wide compatibility in 2013. The results were calculated at the national level. It’s impressive. Only in 2013, new renewable sources are driven by the government’s personnel policy:
The most impressive thing about these RES facilities is that they only have bills for one year. Most of the benefits, especially those related to avoided pollution, will continue to increase, and will even grow, as RES targets increase in the coming years.
The latest Department of Energy report builds on a study the same team conducted in 2014 and focused on compliance costs for renewables at the state level. Research has shown that for 2010–13, the total cost of RES compliance in all states was around $ 1 billion per year, typically less than 2% of average state-wide retail electricity prices.
This new analysis helps to put these compliance costs in context and clearly shows that the benefits far outweigh the compliance costs. The health and social benefits of abatement alone provide an attractive ROI of 7 to 1!
DOE analysis comes at a critical juncture and provides significant value to policymakers in their efforts to move to a low-carbon economy. Here are my three main points regarding the contribution of this report:
The message of this new analysis is clear: accelerating the shift to greater use of renewable energy (and the use of renewables for that purpose) is a great way to reduce emissions, improve public health, create jobs and save consumers money. Wind energy is becoming more and more popular around the world, and both are examples of renewable energy sources. There are many ways to generate energy from renewable sources. These alternatives to fossil fuels will be an increasingly important part of our energy mix in the coming years.
Renewable energy sources are energy sources that are constantly replenished by natural processes. These resources are also often referred to as alternative or renewable energy, mainly because it is a fuel alternative that can replace traditional non-renewable fossil fuels. Fossil fuels such as oil and coal produce energy when burned, but their supply is limited because they cannot be replenished naturally in a short time for humans to use.
Renewable energy sources are beneficial because their negative environmental impact is very limited compared to fossil fuels. In the past, they were too expensive to be widely used. However, that is changing – many renewables are cost effective, and some can be a wise financial decision for homeowners, businesses and governments. Solar energy in particular is a great option for homeowners looking to reduce their environmental footprint while saving money. You can find out how much solar energy you will save by helping the environment with the EnergySage solar calculator.
There are five main technologies that are considered “renewable energy”. We’ve put together an infographic below to compare the five main renewable energy options:
Solar energy is the most common form of renewable energy. Solar energy comes from the sun, which provides the energy our entire planet needs to survive. By using solar panels, we can capture energy directly from sunlight and convert it into electricity that powers our homes and businesses. Solar energy can also be used to produce hot water or to charge the battery system.
Solar energy is good for your bank account and good for the environment. The cost of solar energy is constantly decreasing and installing solar energy in your home will always save money throughout the life of the installation. In addition, producing solar energy does not pollute or release fossil fuels, meaning you can significantly reduce your environmental footprint by installing solar energy.
Another type of renewable energy that we deal with on a daily basis is wind. When you feel the wind, you feel the air moving from one place to another due to the uneven heating of the Earth’s surface. We can capture wind energy with giant turbines that generate electricity as they spin.
While wind power is not always the right choice for an individual homeowner, wind power is becoming increasingly popular in industrial scale applications. All over the world you can see large wind farms covering several square miles. Like solar energy, wind energy is essentially pollution-free and is a growing and important source of renewable energy that supplies electricity to grids around the world. In 2017, wind farms produced more than six percent of the electricity consumed in the United States.
We can produce renewable energy from circulating water just as we can produce it from circulating air. Energy is produced when moving water passes through a turbine, rotating it to generate electricity. This happens in large dams or waterfalls where the water drops significantly in height. Two important sites for hydropower (also known as hydropower) are the Hoover Dam on the Colorado River and the Niagara Falls on the New York-Canada border.
Many renewables have not yet had a significant impact on the overall US energy mix, but hydropower is already a major player. Nationwide, large hydropower plants accounted for 7.5% of the electricity consumed in the United States in 2017, and the number is growing. In addition to large projects such as the Hoover Dam, hydropower can be generated in smaller projects such as underwater turbines and bottom dams on small rivers and streams.
Hydropower is also a non-polluting energy source as there are no emissions from hydropower plants. However, the environmental impact of hydropower is greater than that of some other renewable energy sources, as it can alter water levels, currents, and the migration pathways of fish and other freshwater organisms.
The Earth has a tremendous source of energy within it. The heat trapped during our planet’s formation, combined with the heat generated by radioactive decay in rocks deep below the crust, leads to large amounts of geothermal energy. Sometimes this heat is released in large amounts at once, which we see as volcanic eruptions on the surface.
We can capture and use geothermal energy by using hot steam to spin turbines. In the geothermal spring system, water is pumped underground. When heated, it rises back to the surface as steam and rotates the turbine to generate electricity.
Additionally, geothermal heat can be used directly to heat or cool buildings. Using this technology, known as a geothermal heat pump, fluids are pumped to heat or cool below the earth’s surface, where the temperature remains constant at around 50 degrees all year round.
Geothermal energy, still a small part of our energy mix, is a promising renewable energy source with enormous energy supply potential. For example, in Iceland, geothermal energy already accounts for 90% of household heating needs and 25% of electricity needs. However, there are concerns about geothermal energy, including the cost of building a power plant and its relationship to surface instability and earthquakes.
The most recent example of renewable energy is biomass. Energy from biomass refers to any energy produced from recently living organic matter such as plants or animals. Biomass is a renewable resource because plants can be regenerated relatively quickly and are grown using renewable solar energy. Fuels such as ethanol and biodiesel (both used for cars and trucks) also come from biomass.
Biomass fuels are also considered ‘carbon neutral’, meaning they do not add extra carbon dioxide to the atmosphere. This is believed to be true because, in theory, as long as new plants are planted and grown, when plants are harvested and burned for energy, these new plants will absorb the carbon from burning, resulting in more carbon being added. However, plant life recovery takes time, and the extent to which biomass fuels are carbon neutral is under debate.
If you want to reduce your impact on the environment and save money at the same time, you can take advantage of solar energy. As solar energy prices continue to fall, it’s time to start making energy from the sun.
