2011 was an important year for green innovations and technological advances.
In the world of fuels, a number of strides were made. President Obama announced increased fuel standards for both big and small vehicles in the coming years.
Alternative fuels also made headlines. The use of biofuel for aviation is becoming a reality, after the U.S. military announced it would begin using it, and a joint U.S.-Chinese venture tested biofuel in civilian aircraft.
Solar technology also grew in 2011. Researchers at Notre Dame have invented a house paint that could one day be used to collect solar energy. Elsewhere in the midwest, scientists at the University of Michigan invented an “optical battery” that might eventually eliminate the need for semi-conductors in solar cells.

Vehicle Fuel Standards Improvements
In August, President Obama announced improved mandatory fuel standards for large vehicles beginning with model year 2014.
The Obama administration also introduced a plan, which could take effect in 2017, to raise vehicle efficiency standards to 54.5 miles per gallon by 2025. The Associated Press reported that in 2009, U.S. automakers agreed to increased standards of 35.5 miles per gallon by 2016.
