Re:Eletrical grid Energy doesn't come from oil
You are debating all by yourself again about the best alternative. I don't get into these religious debates.
You wrote:
Straight electric resistance heating can be considered 100% efficient.
And I replied:
Power lines leak by design warming up the outdoors and irradiating the air, wasting 4.70363517 × 10E18 joules every year.
There is no easy, 100% efficient solution!
Furthermore, that amount of wasted electricity is just a little less than what India consume every year and more than what Russia and more than 200 other countries consume by themselves every year!.
The power lines are a giant resistance heater!
Now, talk about 100% efficiency without a smile!
;-)That's all there is to it really...
Now, since you made me waste all that time: I am going to make you jealous a bit: Where I live, 85% heating is electric and 98% electricity comes from hydro. I work on power lines.
Background:
Countries electricity consumption:
https://en.wikipedia.org/wiki/...
The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year:

Loss by countries, 6% was used as average loss:

Re:Eletrical grid Energy doesn't come from oil

Wow!
Of course this is wrong due to energy lost in power lines:

Power Grid Inertia
There is a general misconception about what this battery system is doing. Traditional generation stores energy for short time response (faster then the governor can open or close the throttle) as rotating inertia. So large grids having many generators tend to have plenty of rotating inertia, with the demand for short term storage coming entirely from users.
In the new model with substantial wind and solar, wind and solar has a demand for short term stabilization without bringing along a corresponding amount of rotational inertia storage. What is most likely happening here is that the battery will be dispatched per the grid frequency control signal, rather than the energy dispatch signal.

transmission losses
...With about 65% of that energy lost in transmission, that number doubles.
source: http://insideenergy.org/2015/1...
65% loss?!? What do you think they are they using to transmit, wet string?
The link you cite says "Energy lost in transmission and distribution: About 6% – 2% in transmission and 4% in distribution".
But Britain's a small place, and they don't wheel power thousands of miles (they don't have thousands of miles), so I expect a smaller number is appropriate.

Power from the people
How many new power plants do they estimate they will have to build, to power all of these electric cars? That's a huge amount of power generation moved into central locations. With about 65% of that energy lost in transmission, that number doubles. source: http://insideenergy.org/2015/1... How does more than doubling the amount of energy it takes to run vehicles save the environment? Unless someone is building a solar grid the size of Britain, I don't see this all coming from renewable sources.

Re:tax deducationsGoogle is your friend... there's a lot of stuff out there; some biased (both ways), some not. Samples: http://cen.acs.org/articles/89...
Similarly, several measures to aid oil companies passed in the early 1900s remain of key importance to the industry, Healey notes. These include one provision passed in 1916 to speed up depreciation of drilling costs. A second one, the oil depletion allowance, which became law in 1926, gives oil companies a tax break for depleting an oil reservoir. President Obama has sought to end these breaks but has been overwhelmed by the opposition from industry and its congressional allies.
http://insideenergy.org/2016/1... Is maybe a better read, and details some of the same things... a bit easier to read, depending on the person. Also, almost at the end is a chart showing the historic totals, right before again talking about "first 15 years" or each.
Happy 100th birthday to the “expensing of intangible drilling costs (IDCs) and dry hole costs” exemption! (Born in 1916.) This tax break allows companies to expense the entire costs related to site improvement and drilling of a well in the year that the costs are incurred.
The 90 year old “Percentage over cost depletion deferral” (born in 1926) allows drilling companies to deduct a fixed percentage – 15 percent – of the revenue from each drill site, with some limitations. This exemption is also used by coal, timber and other mineral industries. -
Re:Would have nothing to do with electric cars...
Any same, intelligent human would prefer electric cars to what we have now.
Because burning natural gas and coal to produce power, transmit it over wires (losing about 10% on the way), charge a battery (losing at least another 8%), and then discharge the battery, is better than burning oil on the spot?
Ah, yes, the cars' engines aren't very efficient — true. But the powerplants also aren't very good — losing about 65% right there at generation. Add to that the listed transmission, distribution, and transition losses, and electric cars become a questionable proposition. One a sane, intelligent human (rather than an arrogant idiot pretending) may very well reject...

Re: Wealth Redistribution
You're still wrong about everything that you claimed.
