So renewables (wind and solar) will have to grow as a mechanical consequence which is good because will get cheaper and cheaper and a large park of car batteries will give opportunity for large scale demand management and therefore help with the integration of new renewables.
France has long coasts to develop offshore wind, especially if floating offshore wind becomes a thing.
Terrestrial wind turbines can be sited in otherwise usable land. Or offshore.
>Windmills and solar kill birds at a much larger rate than activists would seem to care about.
A rate which is many orders of magnitude lower than killed by buildings, cats, coal plants, etc. This becomes a complex discussion when localized, sensitive populations are relevant, but on the whole it isn't a big issue.
Wind turbines and solar don't kill a significant number of birds; this is an old myth recently revived by Trump. In the US, wind turbines kill about 300k birds per year, power lines kill 30 million (mostly through collision), cars kill 200 million, and collision with buildings kills _600 million_.
While there's certainly room to improve on bird-wind turbine interactions, it's just not a major problem, and any resources used would be better spent improving the safety of buildings for birds.
Statistics like that have to be adjusted "per capita" in some fashion. It's going to difficult to pick the right units for comparison. Maybe the basis could be birds killed per kilowatt-hours or joules worth of electricity generated (windmills), carried (power lines), and consumed (cars).
The whole bird thing is a complete red herring.
