Geothermal Energy - How Does it Work?

In essence geothermal energy is power harnessed from the Earth itself. Heat from the Earth’s core, which averages about 6,650 degrees Fahrenheit, emanates out toward the planet’s surface. Heated springs and geysers up to three miles underground can be accessed by special wells that bring the hot water (or steam from it) up to the surface where it can be used directly for heat or indirectly to generate electricity by powering rotating turbines. Since the water under the Earth’s surface is constantly replenished, and the Earth’s core will continue to generate heat indefinitely, geothermal power is ultimately clean and renewable.

The Religious Community Services (RCS) Grace House has received a grant from the City of Largo to install six solar domestic water heating systems from Solar Source. The RCS Grace House is an eight -week program for homeless families. The families can stay in an apartment building and save money to give them a head start. Food, clothing and household goods are available to the families, as well as shelter.
