As a more realistic example, I think you can buy locally grown tomatoes in Finland all year round these days, or if not at least pretty close to it. A large portion of them are grown in Närpes, where day length dips below 5 hours in December. Keeping those greenhouses lit and warm is in no way ecological.
- fogihujy 6y agoThe guys in Närpes has an impressive thing going, but they're simply an excellent example on how you can produce things locally if you have a lot of space and cheap electricity available. That doesn't automatically mean it's more efficient in regards to CO2 emission, so you're pretty much proving the grandparent's point; they could probably grow food on Antarctica too.
- VBprogrammer 6y agoAlmost all power plants waste huge amounts of low grade waste heat (typically ~90C water), fossil fuel plants also give off considerable amounts of CO2 which can be used to enrich the atmosphere of a greenhouse. It's a shame there isn't more joined up thinking when these things are planned.
