Re: I've been pointing this out for years.
At the moment, just as everyone is about to start their commute (obviously moderation delay means you'll see this lunchtime), the UK is generating 37% from gas and it's the only really short-term scalable option. So short-term the additional load will be taken up by burning gas, ignoring micro-generation. Long-term maybe we'll get more wind or nuclear. Solar isn't really going to help this time of year.
