Lucid and Rivian having problems

That’s a great video of all the cons of EV technology.

So much for Chuck's default argument that EV's are more efficient:

EVs consume the same energy per mile driven as the most efficient gasoline and diesel vehicles in warm weather, and Figure 2 shows EVs consume 33-45% more energy in cold weather than the highest fuel economy ICE vehicles. For anyone concerned about the energy required to support a vehicle fleet, it would be a mistake to think – as EPA suggests – that EVs require three times less energy compared to the best fuel economy ICE models. EV proponents suggest that the power for EVs is renewable or will become all renewable over time. There are, however, significant limitations to greater renewable energy expansion that suggest we are close to the upper limit on (intermittent renewable supply). Because of the fuel economy misconception explained above, the investment in renewable power generation, infrastructure, and power storage is too low by a factor of three. This is especially important because 68% of California’s electrical power is from combustion-based energy production.

Cold weather operation also poses greater energy drain for EVs than gasoline and diesel vehicles. Testing EVs on the EPA fuel economy test cycles in cold weather (at 20°F), finds EVs consume 42% more energy than the official EPA fuel economy tests (which are done around 72°F) By contrast, gasoline and diesels vehicles consume just 5-15% more energy when operated in cold weather. Figure 4 below represent EVs’ and gasoline vehicles’ cold weather operation. As can be seen, EV fuel economy drops 33-44% below the best gasoline and diesel models when operated in cold weather.?

"EVs do have three times more fuel economy than their gasoline and diesel counterparts, but this is only true when looking solely at the conversion of energy stored in their batteries into power for propelling the vehicle and ignoring the 59% energy losses upstream from power plants and power lines.?"

So Alberta tar sand oil takes a huge amount of energy to produce and refine. So we should add those energy costs in to the ICE calculation too to get a fair comparison?

I cant wait to see the math.

Now if my PHEV is charged by solar in my yard how much loss is there?

Solar and wind facilities can be closer to more consumers which should reduce loss.

And when you look at carbon emissions of hydro and other renewables, the clear winner is wait for it....... renewables!

So the assumptions in the paper apply to california's supply. So is the Alberta grid this inefficient?

California’s statewide average power plant efficiency of 44.4%, less 7% power line losses, for a total efficiency of 41.2% energy efficiency throughout the production and transmission process (a 59% energy loss).?

So Alberta's efficiency of their mostly fossil energy sources of electricity is only 41%?
