    I’ll agree with we should have started 40 years ago. We knew we should have and we did have sufficient technology to take other paths.

    But I’ll disagree on whether we have the technology now. There was a recent post on Lemmy that in a sunny place like Las Vegas, you could replace 97% of energy generation with renewables and batteries. Cheaper. Not just that you can but that it’s cheaper. We have the technology.

    The challenge is always to bring the cost down. We do have technology to create aviation fuel from green sources. We do have several options for fueling shipping that we know how to do. Even if we’re just making ammonia or hydrogen or green diesel, that is a huge step forward that we have the technology for. The problem is we don’t yet have a compelling economic case to (especially since climate change is externalized, not counted as a cost), nor anyone with the fortitude to make it so
