Re: Exceptions for such dual-purpose signs have been arranged.
In most of the EU the "merit order" principle has helped grow the supply of renewables by guaranteeing the feed-in price. The problem has been the reliance on gas-powered electricity plants to shortfalls because it's the most flexible. This was fine as long as gas was cheap but it's now driving the spot price for all providers. However, this isn't really failure of the market per se, just the lack of foresight about diversifying supply even after all the warnings for a continent that is not self-sufficient in energy.
