Learn about what Geothermal Energy is!
What is Geothermal Energy?
Geothermal energy is HEAT produced deep in the Earth’s core!
About 2,900 kilometers (1,800 miles) below the Earth’s crust, or surface, is the hottest part of our planet: THE CORE.
Heat from the core radiates outward - warming rocks, water, gas, and other geological material.
Magma is molten rock (this means partly melted) that contains gas and gas bubbles.
Magma exists in the mantle and lower crust, and sometimes bubbles to the surface as lava.
What is Geothermal Energy?
Geothermal energy is when the heat from the Earth is turned into energy.
The energy can be harvested from the hot water just below the surface or from drilling down to the hot magma deep below the surface.
Power plants are then used to convert the heat into energy!
Geothermal energy is produced during the slow decay of radioactive elements in the earth’s core.
This process is continuous and it never stops, this is why geothermal energy is a renewable energy source.
The heat just 6 miles below the surface of the Earth is 50,000 times more energy than all the oil and natural gas resources around the world!
By releasing a small amount of heat the right way - we can produce electricity.
Geothermal Energy has been harnessed for thousands of years.
Ancient Romans built Spas and baths around natural hot springs.
These allowed people to make use of the naturally produced warm water in a town they called Aquae Sulis.
Around the world using geothermal energy!
Maori women from New Zealand would cook food using the steam as a source of heat!
Save energy!
• We need energy to keep us warm
• Wear a jumper instead of turning on the heating
• What else can you do to keep warm?
The End!
