We can't afford nuclear

In a devastating analysis of nuclear power, Amory Lovins, head of the Rocky Mountain Institute in Denver, Colo., has concluded that it is the least cost-effective way to meet electricity needs, and the worst possible solution for moderating climate change.

I wish I had found his study earlier — it was published last September and updated in January — because, just maybe, a focus on it might have persuaded Queen's Park to alter its decision to spend $46 billion (at today's prices) on refurbishing and adding to Ontario's existing array of nuclear reactors.

Spending this amount of money on nuclear means there'll be precious little left to promote alternatives. The study is available at http://www.rmi.org/sitepages/pid171.php — from the library of publications choose Nuclear power: economics and climate-protection potential.

Lovins' argument is that, first, you get more bang for the buck installing alternatives. And, second, there's a long lead time for building nuclear reactors — 10 to 15 years — yet what's needed are fast and big cuts in carbon dioxide (CO{-2}) emissions. Nuclear offers too little, too late, he says.

To simplify his first point, he says that an outlay of 10 cents could deliver:

1 kilowatt hour (kWh) of electricity from a nuclear reactor (assuming that all government subsidies remained in place).

1.2 to 1.7 kWh from wind turbines (with no subsidies).

2.4 to 8.9 kWh from cogeneration (production of heat and electricity).

Up to 10 kWh of electricity by improving electricity end-use efficiency — using less electricity, often by replacing equipment, appliances, lighting and heating with more efficient alternatives, plus the reduction in demand that comes with shifting of the economy from high-demand manufacturing to lower demand businesses.

In short, he says, building nuclear reactors is uneconomic. Alternatives are leading in the global marketplace and are growing 10 times faster, he says.

Nuclear power, is "a dying industry, fading from the marketplace, overtaken and humbled by swifter rivals." In fact, it's so uncompetitive that "the trickle of orders observed worldwide all come from centrally planned electricity systems," he says.

What it comes down to is this: a dollar spent on nuclear power does less to reduce CO{-2} emissions than a dollar spent on alternatives. Or, as Lovins puts it: "Every $100 invested in nuclear would effectively release an additional tonne of CO{-2} into the atmosphere."

However, as far as climate change in concerned, that barely matters, because climate change is not going to put itself on hold while Ontario spends 10 to 15 years building nuclear plants. Lovins says the main emphasis should be on improving electricity efficiency.

Ralph Torrie of ICF International in Toronto, one of Canada's top experts in energy and conservation, calculates that between 1990 and 2004, end-use efficiency in Ontario freed up the equivalent of 5,000 megawatts of generating capacity. That's four times the amount of new generating capacity actually added during the same period. So, the potential of this alternative is enormous.

It's obvious, then, that instead of pouring money into nuclear plants, Queen's Park could meet its goals far quicker, with less risk and fewer potential problems by helping people and businesses move to greater efficiency in electricity use.

As Lovins says: "If you worry about climate change, it is essential to buy the fastest and most effective climate solutions. Nuclear power is just the opposite."
