Massachusetts bites the battery bullet

[GregLocock]

The People's Republic has just passed a law requiring 5 GW of batteries be bought. The energy content is unspecified, but is thought to be likely to lie between 4 h and 10h, hence 20-50 GWh. Even at the lower end that is a significant proportion of the state budget. https://www.massfiscal.org/op-ed-the-actual-costs-legislature-climate-bill. By comparison one cold windless night in Australia would need 384 GWh

I'll bet I could achieve the goal using capacitors for a heck of a lot less money than batteries.
