    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.

      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.

      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.

        Interestingly you’re both correct.

        We swapped to ICE vehicles as they were cleaner than shit covered streets from all the horses, making a new problem.

        Renewable energy is much cleaner long term- but what new issues are we not seeing? If we through ourselves head first into this (and we need to) what did we miss?

          If we ~~through ~~ throw ourselves head first into this (and we need to) what did we miss?

          literally the only way to know is to do it. same with horses. there’s a 30 year transition period as infrastructure accommodates the world to the new technology.

          I’m very much a proponent of careful planning and going into things with our eyes open. Sadly, I don’t think we are in a position to know what we don’t know or even find it out at this point because we are on a compressed timeline.

          It’s like worrying about the effects of fire removedant from the fire department’s trucks, when your house is on fire… and the other option in the equation is a flamethrower

            Make no mistake, im not saying we should stop. Far from it. Only that we should have had these discussions 30 years ago, and don’t be soo quick to dismiss the next tragedy to focus on this one - we just repeat the cycle.

            You’re right, the timeline is compressed from the 50 years we “thought” we had, down to literally months, and I don’t think people actually realise that. Too bad most targets are 2050, 2060…

      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.
