And this is the reason it’s a crisis. Climate change is a long process, as is changing the entire world economy to face it. It’s not a crisis because of disruptive weather this year, but because we’ve already set in motion changes to the atmosphere that will inexorably make much more serious changes for at least the next century. Even changing just one small sector of emissions, changing internal combustion to battery electric vehicles, will take a couple decades, and is facing constant resistance by conservatives. One small sector. We have to change the entire world economy. There is so much work ahead and we’re already out of time to prevent serious climat consequences. Starting a couple decades earlier would have made a huge difference (although EV technology wasn’t up to it, so we’d focus on other things).
People can’t seem to look at a graph and internalize what it means when the line keeps going steeply up into the future, but Al Gore clearly could. People can’t seem to conceptualize that some actions have long term results, but Al Gore clearly could
Agreed. On batteries this is where I go back to the 70s. When the oil embargo happened they should have been R&Ding hard for better batteries (and solar and nuclear and fusion). If they started some serious battery R&D back then we would be incredibly better off.
And we should have gone off coal in the 80s. AFAIK there was enough NG to replace it, at least in North America.
Getting off coal would be the thing. I don’t know if they would have been able to advance batteries quickly enough regardless of investment, but getting off coal was quite doable. Nuclear fission was still in ascendancy and could have continued ever upward. Wind power was quite practical, even if not at the scale and cost of today. Solar water heating, weatherproofing, and passive solar design could have brought energy needs way down. In that era we had just gone through a radical downsizing of cars from an energy crisis, and we could have required that continue. We had made progress on many pollutants and started recycling: its not difficult to imagine carbon being recognized as a pollutant and efforts started to control it.
Just one thing, wind without batteries or some kind of balancing can actually be quite bad because you have to quickly turn on and off other power sources, which means they're inefficient. My dad says (way back then) they actually found wind increased carbon production because they had to quickly turn on inefficient generators when the wind died down.
Maybe. My parents at that time were on time of use metering, but it was fixed time. For example the water heater was on a timer to turn on at 11pm when electric rates went down.
Put those two together and you could have dynamic demand response even without grid scale batteries
