• All five renewable energy sources can lower dependence on foreign oil.
• Solar energy has the capability to produce electricity in remote areas not connected to the grid and wind lowers the risk of cost spikes and supply interruptions.

Biomass

• Biomass use can lower dependence on foreign oil since biofuels are the sole renewable liquid transportation fuel available.

Geothermal

• Even in freezing climates, everyone has access to the steady 48–55-degree temperatures under the ground’s surface. Geothermal energy is available all throughout the day and every day of the year. Geothermal power plants have average capabilities of 90 percent or higher, compared to roughly 75 percent for coal plants. By having it be more efficient, this aids in diversifying the energy supply.
• The price of geothermal electricity does not vary with fossil fuel supply and demand. This results in a low-cost and consistent electricity source.

Hydropower

• Because hydropower is versatile and can store energy, it’s compatible with other types of energy generation. With more kinds of different generation such as wind and solar being utilized, hydropower can ensure power supplies stay continuous — even when the sun stops shining or the wind stops blowing. By adding to an assorted energy mix, hydropower secures human energy independence and lowers the United States dependency on imported fossil fuels.

Solar

• Solar energy has the capability to produce electricity in remote areas that are not connected to the grid. This is more economic than running vast sets of wires into remote areas, and in turn helps in diversifying energy supply.

Wind

• Adding wind power to the energy blend diversifies the national energy portfolio and lowers America’s dependence on fossil fuels from abroad. Wind energy stabilizes the price of electricity and lowers risk of cost spikes and supply interruptions. With the growing use of electric and plug-in hybrid transportation, wind energy can also lower U.S. reliance on imported vehicle fuels.
