Slide 2
WHAT IS GEOTHERMAL ENERGY AND IS IT RENEWABLE? Geothermal
energy is energy that comes from the heat of the Earth. The heat
comes from the Earths core, but the heat comes up to the crus
Geothermal energy is renewable as long as the crust isnt cooled
down too much. Otherwise, it would take decades for the heat to
replenish itself.
Slide 3
WHERE IS IT LOCATED AND HOW DO WE RECOVER IT? Geothermal energy
comes from the cores heat, but the heat goes to the Earths crust.
The area where the heat comes out is usually around the Ring of
Fire, an area where the tectonic plates move. The continents where
geothermal plants are North America, South America, and Asia.
Sometimes, a natural source of geothermal energy, like geysers, are
used to recover this alternative energy. Power plants also collects
geothermal energy by using an injection well and a recovery well.
The injection well pushes cold water into the crust, and steam will
come up in the recovery well.
Slide 4
WAYS WE TURN IT INTO ENERGY, WHO USES IT, AND WHATS ITS
PURPOSE? If people live near the Ring of Fire, the geothermal
energy is sent underground in pipes to be used for heating homes.
Once the steam at the power plants comes up to the surface, it goes
to a generator to be converted into energy. Anyone can use
geothermal energy, and it is used to heat buildings and to be
converted into electricity.
Slide 5
EFFECT ON ENVIRONMENT Geothermal energy sometimes releases
gases that are deadly to us. If the area being used, and its cooled
down too much, then the area cant be used, due to no more heat. But
eventually, the heat will come back.
Slide 6
IMPORTANT FACTS No fossil fuels are required to collect
geothermal energy. The U.S.A. produces the most geothermal energy,
but Iceland uses the most in the world. Some natural geothermal
sources emit deadly gases. Geothermal energy doesnt give off any
greenhouse gases.
Slide 7
USE GEOTHERMAL ENERGY! We think that geothermal energy is the
alternative source for the future because It doesnt need any fossil
fuels, and it doesnt give off any greenhouse gases. Geothermal
power plants are also small, so that means less land will be
destroyed.
