I don't think it is scammed in a way you suggest in (2). However, there is indeed the issue that buying green energy doesn't necessarily change anything. Existing green energy will simply be sold as green rather than normal energy. That's why you have several utilities (e.g., Greenpeace's own) that guarantee to build new green plants in line with their own demand
