One of the problems with large solar inverters that turns energy into usable electricity is that they are not as efficient and are costly as solar panels. Due to the lack of progress, Google Inc (NASDAQ:GOOGL) is launching the Little Box Challenge, which is an open competition to build small solar power inverters. Google is promising $1 million to the winners, but warns that it will not be easy.
“We have a goal of powering our operations with 100% renewable energy, and to that end have contracted over a gigawatt of wind energy for our data centers. Beyond powering our own operations, we?ve also committed over $1 billion to 16 renewable energy projects around the world. Keep an eye on www.littleboxchallenge.com for more information in the coming months!” said the search giant company in a Google+ post.
