Geothermal energy is the heat coming from the earth and is located under the surface of it. The heat is more extrem the further you go into the earth. Several Miles into the earth you can find the magma rocks, which are extremly hot. However you can already find some heat from shallow ground. More...
We live in a house, where we have a heat pump (Wärmepumpe) and an earth probe (Erdsonde).
The probe goes deep into the earth and takes the heat from the earth. Thanks to a very clever system, we can use that heat to make hot water and to heat our house. Because the heat from the earth is renewable, the system is very ecological. Before the pump and the probe we had to heat with oil, which is not good for our environment. The change to the new system is a very important step for our family and our ecological footprint. More and more families and houses change or already have changed to this ecological system.
In the picture below you can see our boiler at home.
The direct energy, which we all see and know about only makes one third of the whole energy. The rest is embodied energy, which we don't see in a product. It is the hidden energy, the energy used in making the product and it is one of the biggest problems if we want to talk about climate change. This is why we have to get educated in this issue.
