Why do humans burn fossil fuels?

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.

What can fossil fuels be replaced with?

Renewables replace fossil fuel energy on the grid. In the U.S. and in virtually every region, when electricity supplied by wind or solar energy is available, it displaces energy produced by natural gas or coal -fired generators.
