LOL; You're ignoring reality as usual.
Using an apples-apples comparison the embedded energy of a BEV is paid back after ~80k miles. Even when powered by coal (which is less and less likely)
BEVs are still ~20% better than ICE... even if that ICE is a hybrid (unless that Hybrid has a plug
)
I also seem to recall someone whining about using a worst case scenario
That's no math. Just more electric fuzz using average grid mix.
Say, my average tax rate is 15% but my top tier is 3o%. if I earn an extra dollar, what is the tax rate on that dollar?
Same way, when we add BEVs to a system, it is very likely to bump up the consumption of the worst component, like coal.
If not, then that's what should be done FIRST - minimize the use of the worst component. Agreed?
Let's take the example of Indian grid that I was checking recently due to the Delhi pollution and increasing coal usage until recently.
Indian coal plants are at 51.5% utilization. indian coal is also inferior. so they burn 0.7 kg of coal/KWh, which is 0.7 kg * 2.2 lbs/kg * 44/12 (CO2/C) =
5.64 lbs of CO2/KWh. When there are electric cars, these will crank up their utilization by burning more coal to meet extra demand.
Electricity sector in India - Wikipedia
large part of the Indian coal reserve is similar to
Gondwana coal: it is of low calorific value and high ash content, with poor fuel value. On average, Indian coal has a gross calorific value (GCV) of about 4500 Kcal/kg, whereas in Australia, for example, the GCV is about 6500 Kcal/kg .
[74] The result is that Indian power plants using India's coal supply consume a
bout 0.7 kg of coal per kWh of power generation, whereas in the United States thermal power plants consume about 0.45 kg of coal per kWh.
Let's say India replaces 1 million ICE cars like Camry, running at 26 mpg and annual miles of 12k miles.
With this move, India will reduce (by takign them off the road)
12000 miles /26 mpg * 19 lbs/gallon * 1 mil =
8.769 M tonnes of CO2 <= Plain vanilla ICE CO2
Then, the 1M replacement BEVs @ 333 Wh/mile will need:
12000 * 0.333 KWh * 1 mil = 4000 kWh * 5.64 lbs CO2/KWh * 1 mil
= 22.560 M tonnes of CO2! <- BEV CO2 - Net addition of 13.7 M tonnes of CO2
If we replaced the same 1 million cars with hybrid Camrys, then @ 52 mpg these will add back only half of original CO2
A
net reduction of 4.384 M tonnes of CO2.
Now, look at this picture of the polar bear and cub, drifting apart in a soon to melt piece of ice floating on top of the warm water.
Do you really want to produce more CO2? Or less?
I'm not even talking about the other pollutants from coal plants, like ashes. Just CO2 alone will devastate the planet.
CG's take:
1. Electric are are just government schemes to green wash people into buying expensive cars to boost the economy.
2. Electric cars may be helpfulk in CO2 reduction in pockets of the world where extra power is also clean, like Norway. But not in places where the extra power will come from worse sources. In future, sure, they may be better. But not today.
3. If you want results now, hybrids are here for you.
