Microsoft made the biggest renewable energy agreement ever to fuel its AI ambitions

Microsoft just agreed to support the development of 10.5 gigawatts of new renewable energy capacity around the world, a massive amount of electricity to fuel its AI ambitions and climate goals.

For comparison, 10.5 GW of renewable energy amounts to nearly half the amount of solar and wind capacity California had in 2022. This is quite literally a very big deal — effectively the largest corporate agreement to purchase renewable energy to date, according to BloombergNEF. Microsoft inked the agreement yesterday with Brookfield Asset Management, which said the deal is almost eight times bigger than what was previously the single largest corporate power purchase agreement ever signed.

BloombergNEF estimates that it could cost between $11.5 to $17 billion to build out that much new capacity, which is supposed to come online between 2026 and 2030. (Microsoft and Brookfield declined to confirm the dollar amount on the record.)

Brookfield says the deal allows it to invest in new renewable energy projects across the US, Europe, Latin America, Asia, and the Pacific. Microsoft would purchase power generated in each new location.

To be carbon negative by the same date, it’ll need to capture any remaining emissions it hasn’t been able to reduce with clean energy. But carbon capture is still prohibitively expensive and unproven at scale, while solar energy has become the cheapest power source in history.

“Microsoft wants to use our influence and purchasing power to create lasting positive impact for all electricity consumers,” Adrian Anderson, Microsoft general manager of renewables, carbon free energy, and carbon dioxide removal, said in a press release.
