Let's support it~~~

Not to be outdone, Yahoo has gone green in a big way, too. Earlier this year, co-founder David Filo pledged that Yahoo would go carbon neutral, basically by purchasing carbon offsets for their massive electricity usage.

Today Yahoo will go one step further, and they are bringing in actor Matt Dillon to help them. They (Yahoo and Dillon) are announcing the “Greenest City in America” challenge, and will search for the most environmentally friendly city in America. The winner gets a whole fleet of hybrid taxis (or the cash equivalent). Another fleet of taxis goes immediately to New York City.

Yahoo will also urge people to become more environmentally friendly via two handy websites -Be a Better Planet and Yahoo Green.

So who’s the greenest? No idea. But more hybrid cars and solar panels are popping up around around silicon valley, giving the SouthPark guys plenty of material for a follow up episode or two.
