With oil prices topping $120 a barrel and gasoline heading north of $4 a gallon, interest in renewable sources of energy to meet U.S. and global energy needs has never been greater.
Energy from renewable sources has the potential to provide 50% - 60% of the nation's power needs by 2030, if policies are put in place to support the growing technologies, say representatives of the wind, solar, geothermal, hydropower and biomass sectors.
Congress must extend tax credits, set minimum renewable energy requirements for states and cap greenhouse-gas emissions as quickly as possible to ensure continued growth of renewable energy, they say.
For instance, geothermal power production could triple in 10 years, producing up to 15,383 megawatts in 2025, says Karl Gawell, executive director of the Geothermal Energy Association. Generally, 1 megawatt of electricity is sufficient to power 1,000 homes.
Some six million people in the U.S. now depend on geothermal energy in one form or another for their heating and cooling needs. Read the complete article here.
