There is supposedly a smaller nuclear power station type that has been developed by Rolls Royce. Looking over the next 10 years I would go for these opposed to Fracking. The Fracking industry has an history of damaging the environment particularly water supplies. Natural gas is soluable in water. Fracking involves pumping chemicals underground to create mini explosions or fractures to release small pockets of trapped gas. In the USA fracking occurs in areas that have less population density which has reduced the awareness of Fracking pollution. In the UK it would be different where population density is much higher. The gas indisurty is releasing considerable methane into the atmosphere and this is adding to global warming, Some say methane is a bigger problem than carbon.
I am happy for more solar and wind, but we need to significantly develop storage facilities, at present renewables can't be stored, so there is a energy supply risk when the weather is not correct for generating these sources of power.
