Big corporations are helping to make ‘renewable energy the new normal’, according to the World Wildlife Fund (WWF).

AT&T announced this month one of America’s biggest corporate purchases of clean energy via subsidiaries of NextEra Energy Resources, for 520 megawatts (MW) from wind farms in Oklahoma and Texas.

The telecommunications giant has also joined the WWF-led  Corporate Renewable Energy Buyers’ Principles which pushes for big business to adopt green power.

“AT&T’s decision to scale up its use of renewable energy is a signal of the growing power of corporate demand to drive energy markets. Big companies setting big commitments is key to driving our nation’s (USA) transition toward a clean energy future. AT&T is joining the ranks of companies for whom renewable energy is the new normal,” said Marty Spitzer, World Wildlife Fund’s Senior Director of Renewable Energy and Climate.

The AT&T move is very much on trend, with figures released last month by Bloomberg New Energy Finance (BNEF) revealing that corporates are buying record amounts of clean power.
