It's going to be hard for everyone. And by everyone, I mean everyone on the planet, not just this small isle. PP's have stated it is better in Spain, France, Germany, no it really isn't. They all have issues. France has been buying electricity from UK due to Nuclear power issues, shutdowns, and lack of cold water to cool towers. Germany relies heavily on Russia as we know, and is already cutting down on usage, it relies heavily on coal, and gas, both of which need replacing, and it shut down all its nuclear reactors post Fukishima. Norway (a big supplier to us) has had to limit supplies due to hydroelectric underperforming due to drought.
UK is doing well on offshore wind, so the government is investing, but it will take time, and of course the wind needs to blow, and in the meantime, we are all up shit creek until Russia is sorted out.
