In the 1960s & 70s, the US had no problem increasing generation capacity for the rise of air conditioning, and it'll have no problem increasing generation capacity for EVs ... What power companies are waiting for are indicators of persistent demand increases so they can cost justify the massive capital needed for new plants, something that's not yet materialized with EVs at 2%. I'm very confident in capitalism: given the demand, supply is always met. [/QUOTE] How? Generators powered by what?

Since electricity is basically already everywhere, then popping up an EV charge site in your neighborhood - or really anywhere - is pretty trivial ... so you figure, hey, might as well toss one up in my neighborhood before someone beats me to it! Clever! Gawd damn, you're prolly gonna make a fortune ... good thing you're thinking ahead of everyone else! |

There are literally hundreds of studies at this point demonstrating how we can transition to a 100% WWS (wind, water, sunlight) energy infrastructure while maintaining or exceeding current levels of grid reliability. Here are a few: Earth's Future, Applied Energy, Applied Energy, Energy, Energy.
A transition like this will require significant global investment, but modeling indicates that investment would be more than repaid, at least over time, by reductions in negative externalities associated with burning fossil fuels. |

Fair question, and no, not at all. In theory, we could, but the cost and societal disruption would be immense, almost beyond comprehension. The folks who study this generally look at 2050 as the target and the models tell them that's do-able.
My hunch is that it's do-able to get to an 80–90% reduction in CO2 emissions by then, and we can make up the rest with actively removing CO2 from the air, either via natural carbon sinks (e.g., forests) or technological means. But that's just a personal opinion. Every day we wait to start this transition in earnest, though, we're increasing the delta-v, making it that much more challenging when we do get going. |

Yeah I hope we get clean energy and find alternative sources if we want to move this way.
My 5-10 year question is more tongue in cheek due to the forecast of having trouble finding a gas station in 10 years. That is so unlikely to happen. All of these gloom and doom forecasts sound just like "in the year 2000 we'll have flying cars" I heard when I was a kid. Still waiting for Venice to disappear. |

That would be awesome but a good 20 to 40% of our population hates nuclear and they have since the 1970s. I don’t see them capitulating on this. Although in my opinion nuclear is the way to go. It’s never ending and it’s clean energy. Then they could set up all the little charging stations they want. I hope they put a subway sandwich shop at every charging station.

The transition goes way beyond what cars we'll be driving in the future. The entire transportation industry has to change as well; trucks, tractors, ships, trains, planes, and all other petrolium-fueled equipment. The build-out of a charging infrastructure for personal transportation is an easy problem in comparison.

In general, past climate model projections evaluated in this analysis were skillful in predicting subsequent GMST [global mean surface temperature] warming in the years after publication. While some models showed too much warming and a few showed too little, most models examined showed warming consistent with observations… We find no evidence that the climate models evaluated in this paper have systematically overestimated or underestimated warming over their projection period. The projection skill of the 1970s models is particularly impressive given the limited observational evidence of warming at the time, as the world was thought to have been cooling for the past few decades. While climate models have grown substantially more complex than the early models examined here, the skill that early models have shown in successfully projecting future warming suggests that climate models are effectively capturing the processes driving the multidecadal evolution of GMST. |

I just read a dozen weather forecasts telling us to prepare for one of the coldest winters ever! I just wanna know what direction the earth is heading, what do your various studies out of england have to say?? Last edited by GoneIn4Secs; 11-01-2021 at 02:34 PM.. |

You are confusing efficiency with energy density. Besides, someone already did invent something better and more efficient, the train. More goods would be shipped by train, except the teamsters would never have it. But electric tractor trailers make a lot of sense with batteries that can be switched out. It won't be like flipping on a switch, one day it's ICE and one day it's all electric, but range is into the practical numbers and solid state tech is about to put that into 2-3x those numbers. Charging isn't an issue if you can charge overnight at rest-stops. For many industries, electric may take a while and in some, it may never be practical to be totally electric, like longer-distance aircraft, but for tractor trailers that have plenty of volume to store batteries in existing or new aerodynamic shapes, it's a great application.

No one is talking about how these EV cars are more expensive than ICE cars. How much is it going to cost to fix these cars? How long will EV last? What will be done with spent batteries? Do we have infrastructure to dispose these batteries? What’s the environmental impact of these batteries?
