Corporate sourcing of renewable power is now a “mainstream pillar of business strategy”, said the International Renewable Energy Agency (Irena) in a first-of-its-kind study that pegs the level at 465TWh across 75 countries in 2017.

Irena said active renewable power sourcing by companies was almost equivalent to the total electricity consumption of France last year, as it unveiled its report Corporate Sourcing of Renewables: Market and Industry Trends – claimed to be the first comprehensive analysis of its type.
