But the UK has serious energy problems; I'm a squeaky wheel on the topic but their per capita energy figures are estimated to have dropped 30% from peak [0]. You can't startup your way out of a hole like that, someone serious needs to do some capital investment. The UK's energy policy is a sick joke.
A startup involved in helping people to live energy efficiently would probably go great and be a real boon to the people; but it isn't addressing the root cause of the problem here. The squeeze is real.

Unless you leave the country, the 'serious energy problems', whatever caused the bad economy, and anything else in the country are still going to be present if you don't start a startup?
