Speaking of electrical heating. Both in Sweden and France, electrical heating was advocated by the utilities with the reasoning that this can reduce the nuclear-unfriendly daily variability of demand. However, the two load graphs I posted upthread reflect the snag with this: seasonal change. The graph for the first half year of 2010, which includes a heating season, shows lesser variability in total production minus net exports than the first six days of July graph, corresponding to the season when people don't use heating and generally consume less (less need for lights, less TV watching...). So, in the end, electric heating doesn't reduce balancing capacity requirements at all.

At least in Sweden, it was strongly advocated by Vattenfall and was backed by Vattenfalls role as monopoly grid controller. Local utilities that followed Vattenfalls line was rewarded by lower prices on electricity sold to them and higher prices on electricity sold from them. Utilities that did not follow the line was similarly punished. This was regulated in secret treaties (that has expired and are no longer secret) during the period that nuclear power was much debated and a referendum held on abolishment of nuclear power.

The electric heaters are very interesting. I've seen no study on this (but would love to make one), but my hypothesis is that the nuclear overbuild in the 80's in Sweden resulted in an oversupply of power, which had to be used for something. Enter the electric heaters.

What's really interesting is that Swedish power consumption has been pretty flat since 1985 (when the latest nukes came online), but the amount of electrical heating has steadily fallen, after the initial surge in use.

Essentially, the growth in power demand due to economic growth has been hidden by the constant draw-down of electric heaters. Now that that low value-added use of power has more or less been phased out, new generating capacity will be needed to fuel future economic growth.

The idea that the linkage in growth in GDP and power consumption in Sweden has been fundamentally broken, is going to be shown to be an empty shell. This means the projected power surplus of the future will fail to materialise.

Did I mention it would be totally cool to make a study where one can try to falsify this hypothesis? ;)

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

That would be cool, yes.

If you are interested in trying to make such a study, I would guess this institution might be interested:

Chalmers: Energi och miljö: Fysisk resursteori

På avdelningen för fysisk resursteori bedriver vi tvärvetenskaplig forskning och utbildning inom områden som hållbar utveckling, energisystem i ett klimatperspektiv, industriell ekologi samt komplexa system.

Another study I would be interested in: the pumped hydro potential of Europe. I only have a vague idea of what would be the limiting factors.

... in limiting factors between pumped hydro added to conventional hydro, pumped hydro into an artificial reservoir above a natural reservoir, and modular pumped hydro. The first is limited by conventional hydro capacity and rival reservoir uses, the second in a way parallel to coventional hydro by appropriate sites, the last by minimum efficient scale for economies of scale and availability of sites with sufficiently steep slopes and sufficient height differential between top and bottom reservoir.

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