Yes, someone sent it to me for my amusement.
Basically:
1. He pretends that renewables can't really be used to generate grid power because they are "unreliable" even though large grids already include lots of renewables today. California is already averaging 25% renewables on the grid and that's without counting lots of large hydro and some nuclear. CA is on track to go from 25% today to 33% in 2020 and has already set a 2030 target of 50%.
2. He talks about conversion efficiencies of steam turbine generators but forgets to mention co-generation or mainstream combined cycle designs that are 50-60% efficient overall.
3. He doesn't understand grid transmission and distribution at all. He thinks 67% of the power gets lost during transmission and distribution when the actual number is about 6% in the US and 9% globally. He thinks grid transmission is at 440V rather than the 115,000 - 765,000 volt lines that are actually used. He doesn't understand how neighborhood transformers work either.
4. He doesn't understand that the large majority of electric car charging will be done overnight at off-peak hours when the grid has plenty of excess capacity even for huge numbers of EVs.
5. He doesn't realize that his Ford F-150 -- even the new all-aluminum one with the most efficient gas engine option -- emits about twice the CO2 of a large Tesla Model X CUV running on US average electricity (485g per mile vs 250g per mile). Similar numbers apply for an average EV. Numbers sourced from fueleconomy.gov.
It's an obvious hit piece by someone who doesn't understand what he's writing about.
