WHY NUCLEAR ENERGY ?



Nuclear energy already meets a significant share of the world's energy needs

· There are 441 nuclear reactors in operation in 31 countries

· These plants generate electricity for nearly a billion people, and account for 17% of the world’s electricity production


Nuclear energy is needed to meet growing demand without contributing to global warming

· Worldwide demand for energy is expected to double by 2030

· There is an inadequate supply of fossil fuels to sustain future demand, and fossil plants generate greenhouse gases

· Currently, worldwide use of nuclear power avoids the emission of nearly 2 billion tons of carbon dioxide annually

· There is no direct release of carbon dioxide from the fission of uranium to make electricity.

Despite the political fallout from the Fukushima Daiichi disaster in Japan, we shouldn’t give up on nuclear energy.

We are urging to scale back the knee-jerk reaction to nuclear power as dangerous, expensive and unfit for use as an alternative energy source to fossil fuels.

The reason? Because “there are no better alternatives available” — fossil fuels are, by comparison, exceedingly unsustainable.

William Tucker, author of Terrestrial Energy: How Nuclear Power Will Lead the Green Revolution and End America’s Energy Odyssey writes:

Uranium fuel rods sit in a reactor core for five years. During that time six ounces of their weight—six ounces!—will be completely transformed into energy. But the energy produced by that transformation will be enough to power a city the size of San Francisco for five years.

A coal plant must be fed by a 100-car freight train arriving every 30 hours. A nuclear reactor is refuelled by a fleet of six trucks arriving once every two years. There are 283 coal mines in West Virginia and 449 in Kentucky. There are only 45 uranium mines in the entire world. Russia is offering to supply uranium to most of the developing world with the output from one mine. That is why the environmental impact of nuclear is infinitely smaller.

It’s not just fossil fuels, either. Tucker outlines the case against other alternatives that have made headlines recently:

· Natural gas. “Fracking has been able to proceed so rapidly only because it has been exempted from federal regulations governing air and water pollution.”

· Hydro power. “A hydroelectric dam must back up a 250-square-mile reservoir in order to generate the same electricity produced by a reactor on one square mile.”

· Wind energy. “Replacing just one of the two 1,000-megawatt reactors at Indian Point in Westchester County, N.Y., would require lining the Hudson River from New York to Albany with 45-story windmills one-quarter mile apart.”

· Solar energy. “It would take 20 square miles of highly polished mirrors or photovoltaic cells to equal the output of one nuclear reactor.”
