"We’ve been working collaboratively with now, I don’t know it must be well over 30 companies and half a dozen NGOs to identify policies that would make it easier for us as big corporate consumers to buy renewable energy in a really meaningful way with real additionality and in a cost effective way," said Bill Weihl, Sustainability Guru at Facebook.  "And then to work with utilities and regulators to change those policies and that’s a place where we have real power in the marketplace.  It’s not just about us investing our cash or changing our procurement.  It’s about bringing it to change the whole market."
