Green Innovations And Advances Of 2011 (9 of 12)

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.

Bike Sharing Programs

While bike sharing programs may be nothing new for some cities, 2011 was a big year for them. Both New York City and San Francisco announced that they would be rolling out a bike sharing program for the summer of 2012. Chicago also announced that it hopes to bring 3,000 bikes and 300 kiosks to the city by next summer.

These cities hope to repeat the success of Washington, D.C.’s bike sharing program, which celebrated its one-year anniversary in September with its one-millionth trip. The D.C. program has 1,100 bikes and 114 docking stations in the District of Columbia and Arlington County, Virginia.
