variable renewable energy (VRE) sources can only produce electricity when weather conditions are right (i.e., when the wind is blowing or the sun is shining). In contrast, conventional energy sources used to generate electricity are typically available when called upon. Frequently, the energy source can be stored on-site, or

Those who do have elec-tricity pay on average nearly twice as much as consumers elsewhere in the world. Power
Renewable Energy Activities: Choices for Tomorrow
The practical sources of energy include the fossil fuels, natural gas, petroleum (or oil), and coal. Fossil fuels are referred to as nonrenewable energy sources because, once used, they are gone. Scientists are exploring the practicality of other sources called renewable energy sources.

alone” renewable energy must be able to provide reliable power independent of the energy sources it proposes to replace. So to “stand alone,” power from renewable sources must have some method of energy storage, e.g., batteries, which can be turned on to meet demand when wind and sun are not available. The renewable energy sources must ...

What is Renewable Energy? Renewable energy uses energy sources that are continually replenished by nature—the sun, the wind, water, the Earth’s heat, and plants. Renewable energy technologies turn these fuels into usable forms of energy—most often elec-tricity, but also heat, chemicals, or mechanical power. Why Use Renewable Energy?

All renewable energy sources can be converted to electricity. Since some major renewable energy sources are intermittent (wind, solar), fitting such supplies into a grid creates challenges. This is less of a problem for biomass, hydropower, and geothermal. Only a few of them produce liquid and gaseous fuels as well as heat directly. Biomass energy
