Google's new climate vow

• Google says it already buys enough renewable power annually to match its total power use.
• But as we've written about before, that doesn't mean they're never relying on fossil generation for the systems, which they now say will happen by 2030.
• The move also comes amid activist pressure on tech giants.

What they're saying: CEO Sundar Pichai, in a blog post, said it will involve approaches like pairing wind and solar together, increasing use of battery storage, and using AI to "optimize" power demand and forecasting.

Where it stands: Pichai, as part of several new climate announcements, also said that as of today, "we have eliminated Google’s entire carbon legacy (covering all our operational emissions before we became carbon neutral in 2007) through the purchase of high-quality carbon offsets."
