Nuclear power
At present roughly 15% of the UK's electricity is generated by nuclear stations. However the nuclear reactors are all over 20 years old and due to be de-commisioned within the next few years. The government is currently pushing for a new generation of nuclear reactors to be built, and this is being sold as a 'solution' to climate change. While it is true that nuclear power generation results in fewer greenhouse gas emissions than burning fossil fuels, nuclear power produces deadly radioactive waste instead. Radioactive waste cannot be treated, is notoriously difficult to store, and remains radioactive for thousands of years. We have no way to get rid of it so the more nuclear power we generate, the more it piles up.
Several British beaches, such as Formby, near Liverpool, are contaminated by radioaction from nearby nuclear power plants. The authorities warn that you shouldn't swim at Formby more than a couple of time a year. If a new generation of nuclear reactors is built in the UK, we will have to get used to gamma radiation pollution as a feature of the British landscape.
Nuclear power also brings the problem of nuclear proliferation. The facilities and technology neede to build nuclear power stations are similar to those needed to manufacture nuclear weapons. The more nuclear power stations we build, the cheaper and more plentiful this technology will be. The depleted uranium which was used in both wars on Iraq is a biproduct of the nuclear power industry.
In the 70's and 80's the UK stopped building nuclear power stations because the public was overwhelmingly against them. Now that the prices of oil and gas are rising and climate change is becoming such a major public issue the government is telling us that our only option is to accept nuclear power with all the health and environmental problems that will come with it. We do have another option: to massively reduce our power consumption, and to get what power we do use from renewable sources.
