Be interesting to see how this is reported.I kind of doubt the low deaths from solar figure. Those get installed up high on residential roofs and at least a quarter of construction deaths involve falls from roofs.

Around here they're disappearing off the roads and onto the dealerships' used lots, getting traded in for gasoline cars. But Texas is HUGE and an ev wouldn't make it from my house to my best friend's house, whereas my Accord would do it on a 3rd of a tank.Idk where you're at but up here in MA I see more and more of them every day. I can probably spot 3-5 every time I drive anywhere.
Or daytime delivery - like USPS …I could see the best market for evs would be taxi service.
Guessing an EV with a range of 230-300+(Most) would take one 20 min stop to charge to do the trip.Around here they're disappearing off the roads and onto the dealerships' used lots, getting traded in for gasoline cars.

The company I drove taxi for as a second job had some of their taxis running almost 24 hours. 2 separate 12 hour shifts. A day driver drove the 2005 Impala 5am to 5pm and then I drove it 5pm until nearly 5am.I could see the best market for evs would be taxi service.
Out of the other 300-500 ICE vehicles you see.Idk where you're at but up here in MA I see more and more of them every day. I can probably spot 3-5 every time I drive anywhere.
I do agree with the ICE inefficiency at turning heat into work. However, it must be pointed out that transmitting AC power across the grid is also inefficient. A good number for transmission losses are about 10% of what you put into a transmission wire, you don't get out the other end, then there are VARS, which cost more losses, transformer losses, etc. These all add up to maybe 15-20% losses.Even if we used gasoline to produce the electricity we would probably need 70% less gas than currently even if electricity was produced at power plants using gasoline as the fuel source. Internal combustion engines are woefully inefficient, their thermal efficiency averages around 20% of fuel being turned into propulsion. Electric motors turn around 98% of energy into propulsion making them almost five times as efficient. In addition power plants are close to 98% efficient as well with all of their ways of recouping heat(citing coal). It is much more efficient (from a money standpoint and efficiency standpoint and emissions standpoint) to make one or several large power plants that are highly efficient than a separate one in each vehicle (millions).
I see (and hear) these massive lines/towers coming off our nuclear plant and going hundreds of miles … Has me thinking the challenge will be convincing folks that you can safely put the next generation plant closer to the end users …I do agree with the ICE inefficiency at turning heat into work.

I would like to see how a power plant is 98% efficient - pushing back politely, because that number seems high to me.
Steam turbines to produce electricity seem to be more efficient ... maybe that's were the high efficiency numbers come from (?).I would like to see how a power plant is 98% efficient - pushing back politely, because that number seems high to me.
High? It's fantasy, I addressed it in my response to him, to which he never replied.I do agree with the ICE inefficiency at turning heat into work.

See my reply earlier in the thread.Steam turbines to produce electricity seem to be more efficient ... maybe that's were the high efficiency numbers come from (?).
A nuclear power plant to produce steam to make electricity with steam turbines is about as good as it gets.
Then you'd have to find someplace to charge it. Bucees has a few charging stations, but those places are very few and far between here, and always off the beaten path. Cars are always plugged into them with the owners nowhere in sight.Guessing an EV with a range of 230-300+(Most) would take one 20 min stop to charge to do the trip.
Yeah but those are probably roofers who tend to be drunk. Install solar probably pays better so maybe less drunks or less people falling off roofs. Easy for a general contractor to have a worker fall off a roof, harder for a solar company to lose too many employees falling off roofs.I kind of doubt the low deaths from solar figure. Those get installed up high on residential roofs and at least a quarter of construction deaths involve falls from roofs.
IIRC, china replacing distribution trafos to amorphous iron cores. That will decrease losses . But in eu nobody cares.. citizens will pay distribution losses anyway.I do agree with the ICE inefficiency at turning heat into work.
