How to replace traditional electrical energy with clean electrical energy

# data[].attributes.body
To create awareness about the important of use clean renewable energy, in this case eolic energy, instead of traditional production of electricity because it contaminates the environment. Wind provide mechanical power through wind turbines to turn electric generators for electrical power. Electricity is very important for many production processes, and in our daily life.

How can we reduce the energy demands from official providers using eolic energy at home or at school for charging some artifacts?

Biology
* Students will be able to understand and discuss the effects of the combustion of fossil fuels and the cutting down of forests on the carbon dioxide concentrations in the atmosphere.

Physics
* Students will be able to recognise and understand that energy is transferred during events and processes, including examples of transfer by forces (mechanical working), by electrical currents (electrical working), by heating and by waves.
* Students will be able to describe how electricity or other useful forms of energy may be obtained from:
– chemical energy stored in fuel
– water, including the energy stored in waves, in tides, and in water behind hydroelectric dams
– geothermal resources
– nuclear fission
– heat and light from the Sun (solar cells and panels)
– wind
* Students will be able to give advantages and disadvantages of each method in terms of renewability, cost, reliability, scale and environmental impact
