That last sentence, yep. People don't tend to factor in the carbon footprint of building anything they deem environmentally friendly. There's a cost/benefit analysis to be made. A bad idea may actually be worse than what it's replacing, or not beneficial enough to pursue.
There may be carbon emitted in creating green energy but green energy is ultimately reducing demand for hydrocarbons, which is better than sequestration. Also you need to factor into the operational life of the green tech. If you do, it's pretty clear pretty fast that it's beneficial to go with green energy options. The argument you're making is a common strawman argument for not investing in green energy.
For all the things you think of when you hear "renewables", that analysis has already been made, and it's overwhelmingly better in every way to ditch fossil fuels.
I’d assume this is true over any sufficiently long time horizon.
I’d guess it’s like 20 years for a lotta stuff? i.e. short enough the average Lemming would benefit in their lifetime
More like a year. A wind turbine, depending on size, position etc, generates the amount of power used in it's construction within 2.5 - 11 months. Over it's life cycle it generates about 40x the energy you put in.
Incredible, love it!
Thanks for the bright fact :)
People have done those cost/benefit analysis for solar, wind, and EVs. They come out a pretty clear winner. We don't really need to keep hounding on this while pretending to be smart.
Now E15 gas, OTOH? Utter trash that should go away.
