Re: Same in France (4.00 / 3)

In much of the US, the strongest electric peak is in summer, from AC - winter is more a peak for natural gas and heating oil demand.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

Re: Same in France (4.00 / 2)

The differences are very interesting. One might add that in Sweden there is almost no use of natural gas at all, and the little that exists is used to fuel one CHP plant and some petrochemical factories.

They do import gas into France but I'm not sure what they use it for. Cooking?

Peak oil is not an energy crisis. It is a liquid fuel crisis.

Re: Same in France (4.00 / 2)

Half the use is residential, one third industrial. Methinks most of the residential is for heating, even if electric heating has a market share of 60%.

I note that according to this, due to the necessity to use fossil fuel plants to supply the seasonal heating peak, even according to EdF's own calculations, CO2 emissions from electric heating are barely below that from gas: 180 vs. 195 g/kWh.

Aha, I think that the only parts of the ... (none / 1)

... US where electric heating would have anywhere near 60% market share by site would be regions with relatively mild winters and involve quite a substantial amount of reverse cycle air-conditioning in that share.

So the stronger summer than winter electric peak has distinct causes in different parts of the US, where in cold parts of the US such as Northeast Ohio, the strong summer peak is because of limited market share for electric heat and while in hotter parts of the US the strong summer peak is in part because cooling is such a large overall energy demand relative to heating even with high shares of electric heating.

On top of that, power is pretty expensive in the US, even in supposedly cheap places like Texas. Let's not even talk about California...

That's one reason why ... (none / 0)

... many of the electric thermal heating systems of the 60's and 70's ended up being replaced, particularly after the deregulation of natural gas prices, except in places where the actual winter heating task is not especially severe either in terms of average minimum temperature or duration of cold weather.
