Wind energy comes from the wind and has been harnessed by humans since 500-900 BC using windmills to pump water and grind grain. Today, wind energy is used to produce electricity and power things like generators, boats, and windsurf boards through wind turbines. Spain is one of the top producers of wind energy in the world, with wind able to supply 10% of its energy demand, though the United States is the largest overall producer. While wind energy has advantages like being sustainable and having minimal environmental impact, it also has disadvantages such as higher costs and variability depending on weather conditions.

2. This energy comes from the wind

3. People started to use it when the 1st windmills were developed in Persia in 500-900 BC for pumping water and grinding grain

4. We use this energy to produce electricity. Things that work with this energy : Generators, boats, windsurf board, windmills.

5. Wind energy is transformed into electricity. It can be transported through the electric guid.

6. Eolic energy can supply 10% of Spain energy demand. Spain is the third biggest producer of wind energy in the world.

7. The biggest producer of eolic energy the United States of America .

8. Advantages: It is sustainable , It doesn't produce waste products. It has got minimal impact on the environment .

9. Disadvantages It is expensive The turbines may create a lot of noise It is a variable source of energy as you can't predict the weather conditions. Reliability: people can not rely in wind when there is a high demand.
