As is usual with EngX the original thread has become, to me at least, unreadable. I would like to follow along with Stuart Thorp’s link on Nuclear versus Wind power:
This post is comparing the CO2 emissions over time for nuclear and wind power. It gives a 25% capacity factor for the wind generation but like most work supporting wind power it ignores the cost, both financial and emissions, of the back up or storage required when the wind is not blowing as well as the cost of reinforcing and extending the distribution grid.
Bidirectional Electric Vehicle charging in this context seems to be a way to parasitically pass these costs onto the EV user and local distribution systems in an attempt to make wind power generation appear sensible.
How should the back up costs be allocated to intermittent renewable energy sources?
