In the US, renewable energy still only makes up about 20 percent of the electricity mix. When it comes to using renewable energy, Microsoft and other companies with goals to tackle climate change were limited to how much renewable energy electricity grids could provide them. As part of that effort, the company has tried submerging its servers in the ocean and in liquid baths to make them more energy-efficient. Using less electricity in the first place will be a key part to achieving Microsoft’s climate aims. The carbon removal technology necessary to achieve that goal doesn’t exist at scale yet, but Microsoft is funneling money toward its development. The company has pledged to be carbon negative by 2030, meaning it plans to capture and store more carbon dioxide than it emits.
But those building blocks are evolving, Janous says. The tools and the resources we had were somewhat rudimentary,” says Brian Janous, general manager of energy at Microsoft.
“, we were like a kid building with those big chunky wooden blocks. The move is part of a broader push within tech and environmental advocacy to ensure that big energy guzzlers help phase out dirty fossil fuels wherever they work. By 2030, it wants to make sure that its clean energy purchases are actually feeding into the local grids where it operates.
That could change if Microsoft is successful in its new goal. Clean energy purchases don’t necessarily connect to the same electricity grids that the company is plugged into
