Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity, or refine them for use as fuel for heating or transportation. Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels. The Energy Department maintains emergency petroleum reserves, ensures responsible development of Americaâs oil and gas resources and executes natural gas regulatory responsibilities.
Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the Environmental Protection Agency, the burning of fossil fuels was responsible for 79 percent of U.S. greenhouse gas emissions in 2010.These gases insulate the planet, and could lead to potentially catastrophic changes in the earthâs climate.ossil fuels, including coal, oil and natural gas, are currently the world's primary energy source.
