Solar Energy

Energy Sources Of The Earth

Pros about solar energy

We use that kind of energy because it will never end

It‘s environmental friendly 1 kWh of solar energy saves 500 grams of

CO2 emission Independent from fossil and atomic energy

sources The solar cell industry creates a lot of jobs

and is therefore good for the economy It saves money for the gas and fuel import.

That‘s nearly 400 Million € in the EU-Countries 2010/11

Pros about solar energy

Cons about solar energy

The intensity of sun radiation depends on the changing seasons, weather etc.

Sometimes you don’t need the energy when the sun shines

The solar cells can‘t save the surplus energy

You need much energies and raw materials to produce solar panels

The efficiency of solar energy

If there would be an area in the Sahara of 700 x 700 km filled with solar panels at an efficiency level of only 10%, we could cover the current total world energy demand.

Concentration of alternative energies

Private solar panels on roofs

Many private houses in Germany have solar energy panels on the roof.The federal state subsidises the solar panels financially.The base funding for a solar water heating system is 60 € per square meter of collector area, at least 410 € for the facility.

Structure of renewable energies in Germany 2011

Total production 129,1 TWh, which is 20% of the consumption in Germany

Solar thermal energy produced in Germany in GWh

„Solarbunker“ in Gelsenkirchen

In the past the Solarbunker was a coal storage.Today it produces 355 KWh energy.
