[ RadSafe ] Nukes Are Green

"State of Fear" by Michael Crichton relieves fear of "Manhattan under 20' of water",
but its nice to have the Greens boosting nuclear power.  Howard Long

Nukes Are Green

f there was one thing that used to be crystal clear to any 
environmentalist, it was that nuclear energy was the deadliest threat 
this planet faced. That's why Dick Gregory pledged at a huge anti-nuke 
demonstration in 1979 that he would eat no solid food until all nuclear 
plants in the U.S. were shut down.

Mr. Gregory may be getting hungry.

But it's time for the rest of us to drop that hostility to nuclear 
power. It's increasingly clear that the biggest environmental threat we 
face is actually global warming, and that leads to a corollary: nuclear 
energy is green.

Nuclear power, in contrast with other sources, produces no greenhouse 
gases. So President Bush's overall environmental policy gives me the 
shivers, but he's right to push ahead for nuclear energy. There haven't 
been any successful orders for new nuclear plants since 1973, but 
several proposals for new plants are now moving ahead - and that's good 
for the world we live in.

Global energy demand will rise 60 percent over the next 25 years, 
according to the International Energy Agency, and nuclear power is the 
cleanest and best bet to fill that gap.

Solar power is a disappointment, still accounting for only about 
one-fifth of 1 percent of the nation's electricity and costing about 
five times as much as other sources. Wind is promising, for its costs 
have fallen 80 percent, but it suffers from one big problem: wind 
doesn't blow all the time. It's difficult to rely upon a source that 
comes and goes.

In contrast, nuclear energy already makes up 20 percent of America's 
power, not to mention 75 percent of France's.

A sensible energy plan must encourage conservation - far more than Mr. 
Bush's plans do - and promote things like hybrid vehicles and hydrogen 
fuel cells. But for now, nuclear power is the only source that doesn't 
contribute to global warming and that can quickly become a mainstay of 
the grid.

Is it safe? No, not entirely. Three Mile Island and Chernobyl 
demonstrated that, and there are also risks from terrorist attacks.

Then again, the world now has a half-century of experience with nuclear 
power plants, 440 of them around the world, and they have proved safer 
so far than the alternatives. America's biggest power source is now 
coal, which kills about 25,000 people a year through soot in the air.

To put it another way, nuclear energy seems much safer than our 
dependency on coal, which kills more than 60 people every day.

Moreover, nuclear technology has become far safer over the years. The 
future may belong to pebble-bed reactors, a new design that promises to 
be both highly efficient and incapable of a meltdown.

Radioactive wastes are a challenge. But burdening future generations 
with nuclear wastes in deep shafts is probably more reasonable than 
burdening them with a warmer world in which Manhattan is submerged under 
20 feet of water.

Right now, the only significant source of electricity in the U.S. that 
does not involve carbon emissions is hydropower. But salmon runs have 
declined so much that we should be ripping out dams, not adding more.

What killed nuclear power in the past was cold economics. Major studies 
at M.I.T. and elsewhere show that nuclear power is still a bit more 
expensive than new coal or natural gas plants, but in the same ballpark 
if fossil fuel prices rise. And if a $200-per-ton tax was imposed on 
carbon emissions, nuclear energy would become cheaper than coal from new 
plants.

So it's time to welcome nuclear energy as green (though not to subsidize 
it with direct handouts, as the nuclear industry would like). Indeed, 
some environmentalists are already climbing onboard. For example, the 
National Commission on Energy Policy, a privately financed effort 
involving environmentalists, academics and industry representatives, 
issued a report in December that favors new nuclear plants.

One of the most eloquent advocates of nuclear energy is James Lovelock, 
the British scientist who created the Gaia hypothesis, which holds that 
Earth is, in effect, a self-regulating organism.

"I am a Green, and I entreat my friends in the movement to drop their 
wrongheaded objection to nuclear energy," Mr. Lovelock wrote last year, 
adding: "Every year that we continue burning carbon makes it worse for 
our descendents. ... Only one immediately available source does not 
cause global warming, and that is nuclear energy."
