After a quick glimpse of their renderings I'm very skeptical of their 60% efficiency claim.
Suppose you have a nuclear plant that can produce all the energy you need for 10c/kwh. Then a wind farm gets built that can displace 50% of the nuclear plant's production and do it for for 8c/kwh. What is the rate that customers pay? If you're thinking 9c/kwh, the proportionate average, then you're wrong. The nuke plant still needs the same revenue to stay in the black. So they sell half the electricity for twice as much per kwh. Thanks to the addition of "CHEAP!" renewables to the mix, the customers in this hypothetical scenario are now paying 14c/kwh. This will not be politically popular.
Fuel costs are a larger proportion of the total for coal and natural-gas powerplants. So the effect there isn't as bad. It's possible for exceptionally cheap wind and solar to match the fuel-only cost for these plants and actually not raise rates for customers. But no renewables operator would ever sell their electricity for less than the going rate.
Government should insist that weather-dependent renewables have some minimum amount of storage integral to their production.

I look up at the subject line and see 'thegaurdian.com' and think "Yep, sounds about right".
Aspartame has to be the most thoroughly studied compound there is. If there was a big enough problem to be significant on an individual level then it would be unambiguous by now.
If everyone involved only makes profit when the line goes up then the line will mostly go up. Short selling, sleazy as it is widely perceived, is necessary for good price discovery. The lack of good price discovery is why BTC is > 0.
Why are we even talking about these as part of the same conversation? Michio Kaku must have bills to pay.
The grid is going to need huge upgrades anyway. Just building a system to proper size is the correct solution.
