NREL Helps Cut Building Energy Use 50%
The U.S. Department of Energy’s (DOE) Commercial Buildings Program and DOE’s National Renewable Energy Laboratory (NREL) are working with the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and the buildings industry to find ways to reduce the energy consumption of large hospitals, schools, and retail buildings by 50%. Hospitals alone use more than 836 trillion BTUs of energy every year and produce more than 2.5 times the carbon dioxide emissions of commercial office buildings.

According to Pike Research, the number of natural gas vehicles sold in North America will grow around 10 percent a year between now and 2019. GE estimates there are 15 million natural gas cars globally today, and around 250,000 in the U.S.

A new study, Wind Power Electricity: The Bigger the Turbine, The Greener the Electricity?, claims that "greener" electricity can be generated from the wind by building bigger turbines, with a reduction of GWP per kWh of 14% for every cumulative production doubling of size. The results of the study state that the larger the wind turbine is, the greener the electricity becomes.
