WIND ENERGY

Method Of Renewable Energy Production

Introduction

Wind energy is an indirect way of obtaining solar energy , since the winds are generated by the uneven heating of the Earth's surface by the sun. Wind energy is the energy of motion (kinetic) of air currents circulating in the atmosphere.

The Winds

Sunlight warms the Earth      *different angles of incidence

Temperatures and pressure generate winds .      * Cold fronts / warm fronts       High-pressure areas to low pressure areas .

Ecuador and Tropics warmer than the poles .

The Winds

Advantages

Clean energy; Low maintenance cost; Near the consumption sites (avoids

transmission losses); Average length of turbine 20 years; Easy removal ; Abundant and inexhaustible .

Disadvantages

Interference in ecosystems (death of bats, interference on the migration routes of birds) ;

Noise caused by the blades ; Magnetic interference in telecommunications

; Erosion on land .

How it works?

The wind turns a giant propeller connected to a generator that produces electricity.

Conclusion

Wind energy fits perfectly into the current demand for it is clean, renewable and does not cause major effects on the environment. Therefore, there must be investment in the countries, many, like Brazil, have great potential and do not use it, because just investing in no environmentally friendly sources.
