If you’ve always fancied being part of a World Record attempt then today’s your chance. Our friends at Greenpeace are attempting to get the most Facebook comments ever in a 24-hour period with their Unfriend Coal campaign. They’re calling on people across the world to show their support for a Facebook powered purely by renewables and are pretty sure that 50,000 comments will get their attention. Add your voice here.

Having set the social media site a deadline of Earth Day on April 22nd to announce a plan to go coal-free there has, as yet, been no indication that the company is going to replace dirty coal and nuclear power with clean, renewable energy.

Just two of Facebook’s data centres use the same amount of electricity as over 217,000 average UK homes – based on U.S. Energy Information Administration consumption for an average home, in comparison to Ofgem’s definition for a standard UK energy user. Demonstrating the IT sector’s huge growth in demand for energy: at current rates, data centres and telecommunication networks, the two key components of the cloud Facebook depends on, will consume about 1,963 billion kilowatt hours of electricity in 2020. That's more than triple their current consumption and more than the current electricity consumption of France, Germany, Canada and Brazil combined.

Show Facebook the huge support there is for a service powered purely by renewables and help them set the example to rest of the IT industry that green is best here.
