To generate power from geothermal systems, three elements are needed: Heat—Abundant heat found in rocks deep underground, varying by depth, geology, and geographic location. Fluid—Sufficient fluid to carry heat from the rocks to the earth''s surface. Permeability—Small pathways that facilitate fluid movement through the hot rocks.
Solar water heating
Solar thermal collectors capture and retain heat from the sun and use it to heat a liquid. [27] Two important physical principles govern the technology of solar thermal collectors: Any hot object ultimately returns to thermal equilibrium with its environment, due to heat loss from conduction, convection and radiation. [28]

Solar thermal collectors convert solar energy into thermal heat which can be used to run a thermally-activated cooling device, thereby generating chilled water or conditioned air for use in buildings.
How Do Solar Batteries Work?
Common ways to use a solar battery. There are three main ways to use a solar battery: Critical backup mode, self-consumption mode, and a mix of both. The way you use your battery dictates the way it works. For example, a battery used strictly for backup power works differently than a battery used strictly for solar self-consumption.
