.Read the text carefully then do the tasks bellow.                                     Renewable energy
   The use of renewable energy is not new. More than 150 years ago, wood, which is one form of biomass, supplied up to 90% of our energy needs. Today, we are looking again at renewable sources to find new ways to use them to help meet our energy needs. About 10% of U. S. electricity was generated from renewable sources in 2009. Renewable fuels, such as ethanol, are also used for transportation and to provide heat for homes and businesses.

The use of renewable sources is often limited by the fact that they are not always available -- cloudy days reduce solar power, calm days reduce wind power, and droughts reduce the water available for hydropower.

The production and use of renewable fuels has grown more quickly in recent years as a result of higher prices for oil and natural gas. The use of renewable fuels is expected to continue to grow over the next 30 years, although we will still rely on non-renewable fuels to meet most of our energy needs.
