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.

Amazing innovations aren’t limited to adults or older people. Early in 2011, two New York University graduate students showed off their line of sweatshirts that change color when exposed to high levels of carbon monoxide.
A middle schooler from Rhode Island has started a community biodiesel program from used cooking grease that is donated by local businesses and residents. Cassandra Lin’s project was even recognized by the UN.
We can’t wait to see what the youth of the world comes up with next year!
