Driving CO2 Production



As of 2019, the world has more than 7.7 billion people living, working, and using energy on our planet. In the United States alone, there are more than 328 million people. These people use energy for so many different activities; it is easiest to think of energy use by putting users into major categories.

The largest energy-use category in the U.S. is generating electricity. About 40% of all the energy used in this country goes to producing the electricity that provides light and powers our homes, businesses, and industries. The next largest category is energy used for heating, followed by energy used for transportation.

Electricity is produced by several energy resources and technologies. Using fossil fuels, nuclear, biomass, solar, and geothermal energy, most electricity is produced using these sources and generated with steam turbines.
