The United States has depended on fossil fuels (coal, natural gas, and petroleum) for electricity generation. When burned, fossil fuels emit carbon dioxide (CO2).  The United States has tried to reduce CO2 emissions by using less fossil fuels and more renewable energy.  People in Nevada succeeded in reducing the most CO2 emitted from burning fossil fuels in our country.*  The bar graph below shows Nevada’s CO2 emissions per person from the use of fossil fuels between 2000 and 2015.
