Unbeknownst to most, we are lovers of our planet Earth and depend so much on solar power that we're often compared to the mighty Birdman. We cheered during Sanyo's CES keynote when it announced "Think GAIA," and now we come again to applaud Tesco. Joining forces with Solar Integrated Technologies, the British supermarket giant is set to build what it claims to be the "world's largest" solar roof on its new distribution center in California. By the end of the $13 million project, the roof will provide 1/5 of the facilities power and save "1,200 tons of carbon dioxide emissions each year." With all that said, now we have to go and ponder whether or not this is enough for us to leave our beloved Trader Joe's.
