Electric cars represent an optional load that can be timeshifted. Cut the cost of electricity during peak solar hours to half its current rate, and that solar will get used. The current flat rates simply discourage electric cars in California. Hybrids are going to be cheaper to run. This is not an instant fix, but it drives more renewable solar energy, and makes sure that PG+E doesn't have to sell surplus solar to the the grid at a fraction of its value. Of course, there's not always a surplus of solar during peak sunshine, but we have most of the tools in place to optimize for variable charging.

In an efficient data center (Google, Facebook, Amazon...) cooling power - fans, chillers and so on - is typically a single digit percentage of the system power. There's potentially another 10 percent or so to extract from fan power in the systems themselves, but even that is reduced by using large, slow fans or some form of liquid cooling. So maybe there's a 7 percent overall gain in efficiency, paid for by advanced internal liquid cooling systems and the inconvenience of servicing anything in the units. And I don't think land prices are enough to balance the equation. Prediction: project will quietly shut down or move to land in fairly short order.

https://datacolada.org/ Their work is intriguing. However, one of their tools - looking at the distribution of the last digit in a set of data - is obviously subject to fraudsters getting better at creating fake data. I am sure that it applies to other approaches as well. That said, though, the techniques the fraudsters use seem remarkably crude, for example simply duplicating favorable data and salting it into the data set.

Bleach + ammonia creates a chloramine gas, a somewhat less aggressive chemical that's being used instead of chlorine to treat drinking water. In this case NH2Cl. I'm sure the water still tastes really awful and is no good for you, but it would be nice if the authors got the chemistry right.
