     Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in
Fukushima (Japan) last year the issue is back in the headlines. And the world is divided- some countries
are planning more nuclear plants, while others have promised to shut theirs down.
     After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy
are also phasing out nuclear power. But France and the United States remain staunch supporters of
atomic energy. In fact, almost 80% of France's electricity comes from nuclear power, the highest
percentage in the world. And in the US, the Obama administration said it "continues to support the
expansion of nuclear power, despite the crisis in Japan."
     Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power
doesn't create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to
generate energy without contributing to climate change. Britain's chief scientific adviser (John Beddington)
supports this view. He recently said that the world doesn't have the luxury of ignoring nuclear energy.
     Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind
power may be clean, but they're expensive; and right now, they require a lot of investment. This higher
cost of using "green energy" is usually passed onto the consumer. So, while many people may prefer their
energy to come from a renewable source, not so many are prepared to pay higher energy bills. This is of
particular concern while the world economy is in such bad shape.
     The main argument against nuclear energy is that it isn't safe. For a start, nuclear waste is very difficult
to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there
were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in
the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands.
     The nuclear energy issue is very complex. And it doesn't look like it'll be resolved anytime soon. As a
Japanese commentator recently said, "it's been a bad year for the 'nuclear village', but I don't think they're down and out yet." The battle continues.

A. the Japanese commentator is positive about the future of nuclear energy
B. the nuclear energy issue will be soon settled
