"Renewable energy production is almost entirely aimed at the generation of
electricity. However, we use more energy in the form of heat, which solar
panels and wind turbines can produce only indirectly and relatively
inefficiently. A solar thermal collector skips the conversion to electricity
and supplies renewable thermal energy in a direct and more efficient way.
Much less known is that a mechanical windmill can do the same in a windy
climate – by oversizing its brake system, a windmill can generate lots of
direct heat through friction. A mechanical windmill can also be coupled to a
mechanical heat pump, which can be cheaper than using a gas boiler or an
electric heat pump driven by a wind turbine."
