Heat your house with a mechanical windmill (2019)

Renewable energy sources are primarily focused on producing electricity, but there is a higher demand for energy in the form of heat. Solar panels and wind turbines can indirectly produce heat, but a more efficient and direct way is through solar thermal collectors and mechanical windmills. Mechanical windmills can generate heat through friction by oversizing the brake system, and they can also be coupled with mechanical heat pumps. This method of direct heat production is cheaper, more energy efficient, and more sustainable than converting electricity. Heat generating windmills have been utilized in Denmark since the 1970s, and recent studies have shown their potential for cost-effective heat production.
