The Earth energy and the beauty

The Earth energy sources - Earth’s energy comes from the original formation of the planet and from radioactive decay of minerals. The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.

The power of the water

Hydropower, hydroelectric power or water power is power that is derived from the force or energy of flowing or falling water, which may be harnessed for useful purposes. More »

The power of the wind

The wind power is the ability of air movement to do work. Today, wind energy turbines are used mainly for production of electricity. It is a clean and renewable energy source that can produce enough electricity to power huge areas. More »

The invisible power

The energy of the wind is invisible and so powerful that has allowed humans to exploit the surface of the planet long before the discovering of electricity. More »
