Nuclear power produces around 11% of the world's energy needs , and produces huge amounts of energy from small amounts of fuel, without the pollution that you would get from burning fossil fuels.
Nuclear power costs about the same as coal, so it's not expensive to make.
Although not much waste is produced, it is very, very dangerous.
It must be sealed up and buried for many thousands of years . For all that time it must be kept safe from earthquakes , flooding, terrorists and everything else. This is difficult.
Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong , a nuclear accident can be a major disaster.

Renewable energy

Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Solar energy is inexhaustible. Noise free.

A letter and an essay

power plants, and the pro-nuclear scientists argue that it is actually much clearer than burning fossil fuels, which contributes to global warming. Others argue that it is better to get electricity from sustainable resources, such as the wind, the sea, and the sun. Although this sounds like a sensible idea, they are not reliable enough to malntain a constant supply of power. For instance, you cannot produce solar energy at night. Basically, we need a source of energy that will not run out; if it cannot be hydroelectricity or coal-fired energy, it will have to be nuclear. Finding a way of ensuring that nuclear power is safe and cannot be misused is the real challenge. Dear Sir/Madam, I am writing in the hope that you can help me with a problem regarding a camera that I have bought recently. On 24 April, I purchased a Canon digital SLR camera from a duty-free shop at Freetown Airport on my way from Freetown to Wondercity

Cernobyl Disaster

such as cancers and deformities are still being accounted for. • The Soviet government also cut down and buried about a square mile of pine forest near the plant to reduce radioactive contamination at and near the site. Chernobyl’s three other reactors were subsequently restarted but all eventually shut down for good, with the last reactor closing in 1999. The Soviet nuclear power authorities presented their initial accident report to an International Atomic Energy Agency meeting in Vienna, Austria, in August 1986. Elimination of the consequences • Emergency crews responding to the accident used helicopters to pour sand and boron on the reactor debris. The sand was to stop the fire and additional releases of radioactive material; the boron was to prevent additional nuclear reactions. A few weeks after the accident, the crews completely covered the damaged unit in a temporary concrete

there is said to be no evidence of a major public health impact 14 years after the accident. There is little evidence of any increase in leukaemia, even among clean-up workers where it might be most expected. However many of those who survived the explosion might turn up with cancer some 20 years from the accident. Progressive closure of the Chernobyl plant In the early 1990s, some 400 million dollars was spent on improvements to the remaining reactors at Chernobyl to enchance their safety. Energy shortages necessitated the continued operation of one of them until December 2000. Unit 2 was shut down after a turbine hall fire in 1991, and unit 1 at the end of 1997. Workers and their families now live in a new town, 30 km from the plant. This was built following the evacuation. Ukraine depends upon Russia for energy supplies, particularly oil and gas, but also nuclear fuel. Although this dependence is gradually being reduced, continued operation
