and it can be used to store electricity generated off peak to reduce the amount of overcapacity needed and make all those intermittent alternative sources more economical.

For example, utility - scale wind generation, a particularly volatile intermittent power source, requires electricity operators to make significant adjustments to balance generation and load, creating inefficiency in the system.

Intermittent renewables can provide 10 - 20 % of our electricity, with hydroelectric and other baseload renewable sources (see below) on top of that.

The green proposition of electric cars, especially the plug - in variety, is that by promoting the development of electricity generation and energy storage technology development (in the form of energy storage devices such as batteries), electric cars are not only reducing the need for gasoline, but also creates pull factors for the development of grid - connected renewable energy sources such as solar and wind energy by creating new electricity demand and provide energy storage solutions to address the problems of the intermittent nature of solar and wind power.

Environmentalists want to rely solely on solar and wind power — intermittent sources of electricity that need back - up power.

«Since intermittent renewables by definition can not provide a reliable supply of electricity, they must be backed up by conventional fuel sources such as coal, gas, hydro or nuclear.»

Examples include refining ways to securely handle radioactive waste from nuclear reactors; testing repositories for carbon dioxide captured at power plants; and, perhaps more important, improving the electricity grid so that it can manage large flows from intermittent sources like windmills and solar panels.
