I understand your sentiment, but please allow me to correct some misperceptions:
Unfortunately the large corporations are in control. No doubt they will use any excuse to increase your utility bill to offset any extra cost, perceived or otherwise.
Your utility charges are subject to strict oversight by state and federal regulators. You may not like the policies imbedded in the rate structures, but they were the outcome of public proceedings, not the nefarious manipulations of evil monopolists.
What ever happen to the Green Credit program.. pollute here, plant a tree there ? How did that work out ? And then there's the user pay extra to offset your personal CO2 emission. (i.e. for your airline flight) Talk about feel good.
This is still in full swing in Europe; the US never had such a policy. Some private companies set up offset programs to assuage the guilt of high-carbon-footprint individuals. My son refers to these as "carbon indulgences" (compare to the indulgences sold by the Roman Catholic church for centuries).
Certainly, I completely agree something needs to be done, but the best I can do right now is drive my Model S and use the excess wasted power from the coal fired power plant in my area by charging my car at night.
There is no such thing as "wasted power". Power output always equals power consumption + losses. Power plants ramp down overnight, using less fuel, to balance power generation and power consumption very closely, in real time. A mere 10kW load, like a Model S, may or may not require the system operator to ramp up some additional power, but for all purposes of discussions and calculations, you should assume that (on average) charging your car requires some power plant to burn more fuel. That's the bad news; the good news is that power plants are so much more efficient than ICEs (and have better pollution control equipment, usually) that driving your EV causes less pollution than driving your ICE vehicle,
regardless of the fuel. That's the case in the US, Canada and EU, as well as many other countries, because we don't have coal plants with no emissions controls.
Footnote: A large grid like the US Eastern Interconnection can tolerate slight imbalances between load and generation; flipping on a light doesn't require some generator to change its set point, because the operators can allow the system frequency to tail off trivially to absorb the load. This bit of margin doesn't change the fundamentals, though, that generation equals load.
