Page "Electric vehicle" Paragraph 62

Electric vehicles will take advantage of whatever environmental gains happen when a renewable energy generation station comes online, a fossil-fuel power station is decommissioned or upgraded.

Conversely, if government policy or economic conditions shifts generators back to use more polluting fossil fuels and internal combustion engine vehicles ( ICEVs ), or more inefficient sources, the reverse can happen.

Even in such a situation, electrical vehicles are still more efficient than a comparable amount of fossil fuel vehicles.

In areas with a deregulated electrical energy market, an electrical vehicle owner can choose whether to run his electrical vehicle off conventional electrical energy sources, or strictly from renewable electrical energy sources ( presumably at an additional cost ), pushing other consumers onto conventional sources, and switch at any time between the two.
