Hybrid systems that can effectively capture and use electricity are a great idea for combining renewable energy technologies. Solar electricity panels (photovoltaic), microhydro electricity systems and wind turbines are the most prevalent ways of capturing electricity from natural processes of the earth. These can be a great way to offset utility costs on running a system. If you were to use solar electric panels in conjunction with a geothermal heat pump, a large amount of the cost associated with running the heat pump could be taken out, and you could have generated almost everything you need to heat your home.
