You can get different types of "bail out" for different types of companies... It can be "much more expensive" for private equity firm than "normal" SME... You save as many jobs and you save a lot of taxpayers m

Massive investment in energy efficiency, plus big investment in renewable energies and and demand-response, plus a little bit of investment in thermal and electric energy storage would more than do the job, for cheaper, with more resilience

1) That is why you should rely on different (renewable) complementary energy : solar, onshore wind, offshore wind, biomass, hydro 2) You don't really NEED Season long storage, but Season long thermal storage would do the job

Energy can be stored as electricity... or thermally (most of our electricity is used to create heat or cold, that we can cheaply store for days and even months) Reversible damns are for small amount of energy and short term... but most clas

Well, hydro is still a big source of energy... A diversified renewable energy mix, including offshore wind is much less intermittent than what u imagine Massive investment in both energy efficiency and demand-response would reduce the need

The answer of hn_throwaway_99 is interesting I would add that if an attack on bitcoin is detected, there would be some answer to it, and the actual cost of the attack would really rise There is also some complexities to get your hand on eno
