All human activity counts on energy; it is nearly impossible to live without it. It is needed everywhere. Without it we will lose all the modern technology. Now the number one source of energy is fusil fuels, but after about 50 years they will be finished, so it is important to start thinking about a substitute. That is what I am going to show.

This project is giving a solution to the problem of energy sources. I am going to look at the electrical source (the most important). The electricity stations will all use three systems. It will use the main three sources of energy in nature:

? Waterfalls, Rivers

? Wind

? Sun light

Waterfalls and Rivers: in every waterfall there will be an electricity station, which will transfer the kinetic energy using turbines to electric energy. In the summer the ice on the top of the mountains will melt, so there will be lots of rapids.

To get benefit from these rapids they will be guided to a path where they are used. Fast flowing rivers especially in Europe will also be used in a similar way.

Wind: wend force will be a secondary source because it is not reliable. In windy days wind turbines are used to produce power. This power will be used in stage 2 of the project to store energy.

Sunlight: Sunlight will be used in the hot deserts. There huge space is found to put large solar cells to produce the energy needed for the countries that don't have any water energy.

Stage 2

Stage 2 is mainly storing energy. At night the power is not needed that much, so electricity will be lost. Prevent this from happening this power will be used to rise water up a manmade waterfall. Then when...
