While I appreciate that Rolls Royce isn’t going to pivot to insulating old houses anytime soon, there are far cheaper ways to solve energy supply/demand problems. Given that a large portion of this almost always ends up funded by a government, though, I wish the UK government would spend efficiently instead of on megaprojects. Emissions could be so much lower right now.
