U.S. energy demand still increasing

Research from Frost & Sullivan finds that U.S. energy consumption will increase by 7.3 percent over 2010 levels during a 10-year period. To meet this demand, solar photovoltaic (PV) and wind power will be the fastest growing renewable technologies, representing more than 40 percent of electricity generation in 2020, supported by a focus on domestic energy production and sustainability.

The U.S. accounts for 26 percent of the world's energy consumption and corresponding greenhouse gas emissions, according to the research. The nation currently imports nearly 30 percent of the energy it consumes, and minimal reduction in imports is anticipated to 2020.

The report also noted that, while trying to address the issue of energy dependence on foreign supply in light of forecasted unremitting growth in energy consumption, the U.S. has embarked on its most aggressive movement toward a sustainable future. Renewable energy, greater efficiency in consumption, and more intelligent transmission and distribution methods will be the main focus for overcoming future energy challenges.
