The big news, here in the UK, is the government's announcement that the UK is to ban sales of new Petrol & Diesel powered cars and vans from 2040. I assume the ban will include hybrids too. This is all very well, but our nuclear power station are coming to the end of their life and no one is in a rush to build new ones. Renewables are on the rise but still have a way to go. They recently closed my local coal fired power station so it will all be on oil and gas fired power stations. Fracking appears to be a non starter here too. So most of our oil and gas will have to be imported. Mind you, our petrol already has to be imported, so nothing new there. And all in the cause of reducing pollution.
