In the U.S. southeast, where winters are mild, heat pumps are increasingly
popular.

Tucson Electric signed a power purchase agreement last week for solar plus
storage at a price of less than 4.5 cents per kilowatt-hour (kWh) over 20
years. That's less than half the price of retail
I was basing my comment on the UK, where currently natural gas and
petrol each represent more than twice the energy usage than
electricity. See chart 1.04 in

WPPSS had the same cost overrun experience 35 years ago and cancelled 3
reactors.
Big reactors and crummy top management are prone to create a disaster. The
“Nuclear Village” in Japan is the latest example. China and

Just considering electricity production and ignoring heating and
transportation is a very common way of misrepresenting how much progress
we are, or are not, making in reaching the point where we have a fully
sustainable set of energy sources

Exactly zero percent, unless you include nuclear powered aircraft carriers.

Yes - Nuclear accounts for 20% of electric production, but almost zero
percent of the remainder of the total energy mix -- which includes
energy for heat and transportation, in addition to electricity.
Thus, as stated, nuclear represents 10% of total energy

Nuclear plants produce 20% of U.S. electricity:
