It can't be said often enough, so I'll say it again:

Solar and batteries can power the world! It's cheaper than gas (esp. at today's prices) and a lot more reliable.

By 2030, solar and batteries could supply 90% of electricity to 80% of the world's population for < €80/MWh (including backup).

It's obvious now that solar and batteries are going to be the cheapest, most reliable, and least volatile way to expand a power grid. Increasing dependence on fossil gas generation now—as many governments are contemplating—would be a terrible mistake, both economically and geopolitically.

@chrisnelder They're the marginal resource in IRPs, at least for #CA

@andybrwn There are a few different ways to interpret "marginal" here, so perhaps you'd like to expand on that and clarify?

@chrisnelder It's what's getting used for setting the marginal energy capacity cost for PG&E (plus a number of assumptions) per public testimony

@andybrwn Ah. Interesting!
