They are a lot of nature forces, that people can use as a power sources. But the biggest one and this, that can be used almost everywhere on the Earth is the SUN.

Solar technologies can provide electrical generation by using heat engines or photovoltaics. And when this solar lights are converted to electrical energy we can use it everywhere in our homes. And there are some samples where we can use the Sun: space heating and cooling through solar architecture, potable water via distillation and disinfection, hot water, thermal energy for cooking, high temperature and electrical process for industrial purposes, etc.
