There isn't much good news on energy prices but it is not all bad.
Nuclear.
It's going to cost £100 billion to decommission Sellafield and after 50 years we still can't come to a conclusion what to do with the waste from previous operations, let alone current ones. Meanwhile we are probably going to inefficiently fund another 3.2GW monster that we really need for baseload.
Wind.
This is kind of going OK. The real issue at the moment is distribution and to improve that we're going to need a lot of investment to move the energy from where it is generated to where it is needed. Current projects are going slowly for a number of reasons and Dogger Bank is behind schedule. I don't think the public in general has any clue about the scale of the operation that is going on in the North Sea to install wind power.
Solar.
This was going great guns around 2015. If we had carried on at that rate we would have installed solar equivalent to HP C by now (about 30GW at 10% capacity factor). But we didn't. Solar is kind of complimentary to wind but we have in no way balanced the two. We should have forced the Chinese to set up panel producing factories here and pushed it harder.
Gas and Fossil Fuels
This is effectively being managed by public opinion, and the public has no clue how the industry works. It takes 10 years to get an oil/gas installation up to speed, it can't be done on a sixpence. Rather than being properly sunsetted, the plug has been pulled and that is going to have some consequences both for energy prices and energy security in the medium term.
Energy Saving
Governments as usual are mismanaging the use of money into things like boiler/heat pump replacement schemes. I doubt whether the use of this money is going to get any more efficient. Of course all these schemes have to be paid for by someone.
I don't think the energy situation is as bad as some people make out, but no it isn't great either. The consequences are going to be that we have to pay more for energy and that means less disposable income. Most people will have less money to spend on pets and tv subscriptions, but energy will remain something that is largely affordable IMO even at the cost of discretionary spending.
Energy security could be a little rough for the next decade but after that a bit easier and we should be more self reliant. I know a few people who have been predicting we would have to ration gas at some point for about the last decade, but it has never happened, despite our relatively limited storage capability and the demise of storage fields like Rough. Maybe if we had December 2010 again it could get a bit dicey.
