Electric car direct subsidy $7,500 per vehicle

Cars promote sprawl and growth. Cars and car infrastructure are subsidized. Growth is the biggest threat to the biosphere. Electric cars are just another excuse to subsidize growth.

dailykos: "Most of us Nissan Leaf drivers got our cars via a Nissan lease deal. It’s a win-win: Nissan gets its Leafs out the door, bags the $7500 Federal rebate, plus some of the car’s value from us (as down/monthly payments), then gets the car back in 2-3 years to sell it again. Meanwhile, because Nissan factors the full $7.5k into the lease deal, we get a much cheaper lease than for comparable ICE cars, and can partake in the EV revolution without the risk of getting stuck with a badly depreciated, outdated tech product."

65% energy lost before wheel turns on electric car

sciencedirect: "The WTW efficiency for EVs running electricity derived from a stationary power plant is shown in Fig. 4. Natural gas from the pipeline is fed into the stationary power plant, which has an electrical generating efficiency that depends on the type of power plant. The electricity is then distributed to the grid, where it is subject to T&D losses resulting in a WTP efficiency of between 28% and 45% depending on the power plant technology. Electricity is transferred to the EV via a charging station, which is on the order of 85–95% efficiency. The battery-to-wheel efficiency of an EV over a drive cycle can range from about 79 to 91% depending on how regenerative breaking is accounted for [41]. This gives an overall WTW efficiency of between 22% and 35%."

#Renewableenergy is a cover for energy-subsidy and growth

Greentech Media : "The Trump administration will need to enact policies that would help de-risk these investments, maintain the United States’ technological competitive advantage, and bring the best, most efficient and advanced technologies to bear to power the American economy. As a starting point, they can draw on the innovative financial models developed by U.S. green banks. These institutions can provide the Trump administration with a model for creating economic growth through visionary, effective financial innovation."
#Renewables mean growth, growth means heat, heat means clathrates will melt. When that happens emissions will far surpass what was saved by renewables.

#carboncapture - so far only capturing money

US News : "Kemper's two gasifiers convert soft lignite coal mined at the site into a synthetic gas using high pressure and heat. The tubes broke March 9 in a cooling unit that reduces the heat of the gas that comes out of one gasifier before piping it into a chemical plant that removes carbon dioxide and other chemicals. The gas is then burned in turbines to generate electricity.

Spokesman Jeff Shepard said the company is working on restarting the second gasifier. The first one continues to run.

Kemper is designed to capture 65 percent of the carbon dioxide from the burning coal, releasing only as much of the climate-warming gas as a typical natural gas plant does."
