Chapter 16, Problem 1TYC

To determine

The proportion of energy now comes from renewable sources and most prevalent form of renewable energy used and the form of renewable energy that is most used to generate electricity.

Answer to Problem 1TYC

Major part of renewable energies is used is the generation of electricity and other percent in used as fuel, heating water, and so on

Explanation of Solution

Renewable sources of energy contribute a little in the global population. About 22% of electricity in the United States is generated by renewable source of energy.

The U.S uses only 9.9% of renewable sources which includes hydropower, bioenergy, geothermal, solar, and wind energy.

Most of the prevent form of renewable energy consumed by the United State is bioenergy. Bioenergy is the energy which is most widely used in the U.S. Bioenergy is the energy derived from the biological materials and sources.

The electricity in United States is generated by using the following form of energies:

• Geothermal energy (2.3%)
• Solar energy (5.7%)
• Wind energy (18.8%)
• Hydropower (24.7%)

The generation of electricity is mostly contributed by the 25% of hydropower renewable source of energy. Geothermal energy is the least renewable energy used in the generation of electricity.
