fracking is extremely unlikely to help... best estimates suggest the UK has enough shale gase to meet less than ten years of energy consumption... and such gas as there is is very deep and expensive to extract... even producing it at all will take years and the benefits will be short lived...

fracking companies insist that 50 year deposits are available but in the immortal words of Mandy Rice-Davies… they would say that wouldn't they!
If the govt had listened to Insulate Britain then UK energy demand would be significantly lower in the winter than it is now... they were absolutely right. Renewable energy sources are also much cheaper and usually faster to produce too... nuclear power is probably our best bet long-term but it is slow and costly.
