In summary, the reason why wind turbines are expensive is mainly due to the combined effects of high manufacturing costs, large technological investment, high installation costs, environmental factors, as well as market demand and production capacity constraints. I want to. . Wind power is a capital-intensive means of generating electricity. as such, it competes with electricity generated by nuclear or coal-fired generating plants (with or without carbon capture). However, because wind power is intermittent, the management of electricity systems becomes increasingly. . Enormous subsidies for solar and wind generation technologies are proving much more expensive than advertised. They also carry hidden costs and burdens on the grid, most recently seen in the Spain blackout.
