Small "plant" nearly covers the energy use of a single American home. Not much space taken up. This is probably way more than I'd need for off-grid living in a Yurt. But I could harness solar and wind power for all my electric needs.
Natural resources are a must for my dream home, which mean in the summer months, so are these: spinning photovoltaic cones have been able to generate 20 times more energy than traditional static, flat solar panels.
savonius wind turbine - Google-haku Eräs mitoitusehdotus Savoniukselle Unfortunately, Savonius wind turbines typically only have an efficiency of around 15% - i.e. just 15% of the wind energy hitting the rotor is turned into rotational mechanical energy. (This is much less than can be achieved with a Darrieus wind turbine which uses lift rather than drag.)
