Big tech companies are becoming the top buyers of green energy to meet data needs

Bloomberg New Energy Finance (BNEF) data shows the tech industry has signed deals for 10.4 GW of renewables and tech-related corporate purchasing has already set records this year.

As more devices are connected to the internet, data flows are expected to grow rapidly. Cisco expects a 75% increase in global data as the internet of things (IoT) expands.

Google has become the largest corporate buyer of renewable energy in the world, as it tries to eliminate all emissions from its footprint, but other big names like Facebook, Apple and Microsoft, are also investing heavily.
