I should explain that in Atlanta, when they install a heat pump, they
include a small, auxiliary, el-cheapo gas fired furnace along with it. It
seldom turns on. I don't know about Florida and other warm places.
In rural Japan where the walls are made of paper, they used to heat with
kerosene

Canada.
Are they putting in resistance heaters? Those are extremely efficient. I
find it hard to believe they
Oil and gas furnaces are now being banned in new construction projects in
parts of Canada. In some places after 2023 you won't be able to replace old
furnaces with new furnaces. This will further increase the demand for night
time electricity.

Few thins are really free, of course especially if carbon fuel is consumed. But
basic transportation can be much smarter and less costly, perhaps fuel-free and

What happens when everyone who currently owns a gasoline car buys an
electric car and
is charging overnight? Would it make sense for the utility companies to
continue offering huge discounts for over night charging?

It is actually 5.6 times more money per mile, because the power companies
offer a huge discount for recharging overnight. In Atlanta, the power

A cold outdoor temperature has a drastic effect on a Prius or a purely
electric car. But the air conditioner does not.
With a Prius in winter, efficiency is very low until the engine warms up,

There is a backstory that makes the Musk Apr1 farcical endorsement of hydrogen
more curious to those on this list.
Elon had done a rather solid and logical interview a few months back - it's on
YTube - in which he strongly put down the notion that H2 had any chance to
