If gravity were a little weaker than it is, it would never have been able to crush the core of the sun sufficiently to ignite the nuclear reactions that create sunlight; a little stronger and, again, the sun would have burned all of its fuel billions of years ago.

Indeed, he has evidence: the speediest drop in greenhouse gas pollution on record occurred in France in the 1970s and «80s, when that country transitioned from burning fossil fuels to nuclear fission for electricity, lowering its greenhouse emissions by roughly 2 percent per year.

Others, meanwhile, could reduce future nuclear waste burdens by operating for decades without refuelling, burning up more of their fuel and generating smaller volumes of waste.

If scientists conclude that the burning of fossil fuels is inducing unacceptable global climate change, then we have a limited number of alternatives to turn to: solar - based sources (photovoltaics, ocean, wind, etc.), nuclear fission and fusion.

Decades of research indicate that when a star heftier than eight suns burns up its nuclear fuel, it will begin to collapse under its own gravity, starting at the core.

There are several reasons for this: the contraction of energy - intensive heavy industries, such as iron and steel; the long - term malaise in the national economy; the modest move away from burning fossil fuels that produce carbon dioxide towards nuclear energy; and the increasingly efficient use of energy evident in most of the economies of the rich world.

Japan has pursued fast - breeder technology, through which a reactor can produce more plutonium than it burns in hopes of cutting or eliminating imports of nuclear fuel.
