Subjects Description Introduction to Renewable Energy, Second Edition covers the fundamentals of renewable energy and serves as a resource to undergraduates in renewable energy courses, non-specialists within the energy industries, or anyone working to support the successful implementation of renewable energy.
What are the benefits of renewable energies—and how do they improve our health, environment, and economy? These gases act like a blanket, trapping heat.
In the United States, about 29 percent of global warming emissions come from our electricity sector. Carbon dioxide CO2 is the most prevalent greenhouse gas, but other air pollutants—such as methane—also cause global warming.
Different energy sources produce different amounts of these pollutants. To make comparisons easier, we use a carbon dioxide equivalent, or CO2e—the amount of carbon dioxide required to produce an equivalent amount of warming.

This primarily affects to the energy gained from biomass which has the same effect as fossil fuels, and that is CO 2 emissions when combusting, but carbon circle is at least closed in that regardbouddhiste.com://regardbouddhiste.com
In contrast, most renewable energy sources produce little to no global warming emissions. The comparison becomes clear when you look at the numbers. Burning natural gas for electricity releases between 0.

Different sources of energy produce different amounts of heat-trapping gases. As shown in this chart, renewable energies tend to have much lower emissions than other sources, such as natural gas or coal.
Increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce US global warming emissions. For example, a UCS analysis found that a 25 percent by national renewable electricity standard would lower power plant CO2 emissions million metric tons annually by —the equivalent of the annual output from 70 typical MW new coal plants [ 4 ].
Improved public health The air and water pollution emitted by coal and natural gas plants is linked with breathing problems, neurological damage, heart attacks, cancer, premature death, and a host of other serious problems.
The pollution affects everyone: Wind, solar, and hydroelectric systems generate electricity with no associated air pollution emissions. In addition, wind and solar energy require essentially no water to operate and thus do not pollute water resources or strain supplies by competing with agriculture, drinking water, or other important water needs.
Biomass and geothermal power plants, like coal- and natural gas-fired power plants, may require water for cooling.
Hydroelectric power plants can disrupt river ecosystems both upstream and downstream from the dam.
A relatively small fraction of US electricity currently comes from these sources, but that could change: In fact, a major government-sponsored study found that clean energy could contribute somewhere between three and 80 times its levels, depending on assumptions .
And the previously mentioned NREL study found that renewable energy could comfortably provide up to 80 percent of US electricity by Jobs and other economic benefits Two energy workers installing solar panels.
Solar panels need humans to install them; wind farms need technicians for maintenance.
This means that, on average, more jobs are created for each unit of electricity generated from renewable sources than from fossil fuels.
Renewable energy already supports thousands of jobs in the United States. Inthe wind energy industry directly employed overfull-time-equivalent employees in a variety of capacities, including manufacturing, project development, construction and turbine installation, operations and maintenance, transportation and logistics, and financial, legal, and consulting services [ 10 ].
Other renewable energy technologies employ even more workers.terminated for the following categories of non-renewable energy property: alternative energy property such as synfuels equipment and recycling equipment; equipment for producing gas from geopressurized brine; shale oil .
