Guy Sorman: Nations planning for life after nuclear

The meltdown at the Fukushima nuclear plant has sent political aftershocks racing around the globe. More often than not, however, the shocks have been ideological, with no basis in science.

The managers of Tokyo Electric Power (TEPCO), which operates the Fukushima reactors, have been justly criticised for using an old generation of poorly maintained generators. The Japanese, who perceive themselves as the world's best engineers, now feel humiliated.

But, despite street protests, the collective reaction in Japan has not been to repudiate nuclear energy. After all, the Fukushima accident has severely injured only a few people - probably less than a dozen workers are dangerously irradiated.

Almost all of the thousands of Japanese victims were drowned by the tsunami wave, not wiped out by a nuclear meltdown.

Japan will not stop using nuclear power. Instead, its engineers will develop better and safer plants, most likely relying on the miniaturised nuclear reactors that were planned to replace the ageing plant at Fukushima. Most Japanese have remained rational in the face of their country's tragedy, as have most people in neighbouring Asian countries like China and South Korea, which, likewise, have not abandoned their commitment to nuclear energy.

This is not the case in Europe and the United States, where Fukushima's ideological aftershocks have been most destructive. German chancellor Angela Merkel's government was the first to decide to close down all nuclear reactors in the coming years - a radical move driven by domestic politics.

Ms Merkel's government does not include Germany's Greens, but the Green ideology has become a widely shared national creed in Germany.

Indeed, one can relate popular hostility toward nuclear energy to Germany's traditional romantic cult of nature, not to science. Germany's nuclear plants will be replaced by more thermal plants, implying a large increase in German carbon emissions - so much for Green concern with global warming. A Germany without nuclear power of its own will be compelled to buy it from France, which has no intention of closing its nuclear plants.

In the US, the ideological aftershock is closer to Germany's than to France's: the US may not be overly prone to romanticism, but a cult of nature remains part of the American psyche. This may go some way toward explaining why the Democrats, who control the presidency and the Senate, are so committed to so-called alternative energies.

President Barack Obama's administration has thrown billions of dollars at wind, solar, ethanol and other alternative-energy resources.Now the Fukushima tragedy is being used to justify continuing these economically dubious programs.

The most promising breakthrough may well be the discovery of huge reserves of shale gas all over the planet.

This could reduce dependency on Opec oil and gas while reducing carbon emission. Gas generates ten times less carbon than biomass or ethanol, which ecologists so heavily promote.

Beyond Fukushima, future energy supplies will most likely rely more on miniaturised nuclear plants and shale gas.

Such a renewed energy balance would impact the current global balance of power. Shale gas is abundant in Europe and North America, in contrast to oil and gas.

Thus, the energy of tomorrow could well reinforce the world's democracies and weaken its most repressive regimes, where most oil is to be found nowadays. Within this new geopolitical framework, green ideology will survive like a cult or a recipe for economic suicide.
