A french consultant/teacher who regularly make 1 hour or 2 hour presentation said that generally, renewables like solar and wind always benefit the coal/gaz industry because you can't have wind and sun on demand, and it's highly impractical to store electricity. so you always complement renewables with coal/gaz. So in the end, the coal/gaz industry benefits from renewables and they would obviously advocates for those renewables. Not to mention you need a lot of metals (which emit co2), other resources (and energy) to build those renewables. Installing wind turbines is no easy task either. It's crazy how the interests of coal/gaz would intersect the arguments of greenpeace, but it actually does.
