For electricity generation, yeah. What it is that stops us from using it for residential heating? Eg, space heating and for hot water. Is it just the proximity to big power plants that makes it unfeasible?
- phonon 9y agoIt's hard to distribute heat...you would need steam or at least hot water pipes everywhere. You would also need to vent the steam when it's not needed...so if you only need the heat for a few months of the year, you don't get that much efficiency increase overall. It's been done though. https://en.wikipedia.org/wiki/District_heating https://en.wikipedia.org/wiki/District_heating
