Questions
How does the amount of offshore wind compare with the estimates in Without the hot air?
A calculation: 530TWh/y = kWh/y. Assuming a population of 60 million, this corresponds to
per person. This can be compared to MacKay’s estimates of 16 kWh/day for shallow offshore wind plus 32 kWh/day for deep offshore wind.
27 TWh a year of carbon-neutral gas is produced and used as backup, producing about 14 TWh/y of electricity. Gas turbines with about 400 TWh/y maximum capacity are needed for this. That seems like a lot of spare capacity: is this a big problem?
