Google is not really 100% renewable in any meaningful sense. Google (and others) buy renewable energy, but that doesn't mean their purchases match up to what their data centers actually consume for the simple reason that data centers have a pretty consistent load and wind and solar do not produce electricity consistently. For truly progressive companies in this area, they need to consider matching the hourly generation and loads, not not just annualized generation and load: https://cleantechnica.com/2019/05/27/100-renewable-does-not-...
This seems like an overly negative assessment. If Google can pay someone else to use solar during the day instead of coal surely we can give them credit for being 100% renewal. After all the opportunities to do this temporal shifting of renewables are exhausted, maybe then it's fair to level this criticism.
