History of Wind Energy

Posted on by Voltsys Team
  • The concept of “Windmill” has been prevalent throughout the world for ages. From as early as 200 BC simple windmills were used in China for pumping water. The Persians built windmills in the 7th century AD for milling and irrigation.
  • It was by the help of this wind energy that ancient explorers took to the world and explored the unknown. The ability to harvest winds in sails determined a country’s ability to be a superpower. .
  • By the 18th and 19th century, windmill had become one of the trademarks of Europe which was mainly used for milling of grain and water pumping.
  • The first wind powered electricity was produced by a machine built by Charles F. Brush in Cleveland, Ohio in 1888.
  • The first vertical axis wind turbine which is also known as the Darrieus turbine, was invented by George Darrieus in 1920s. The Darrieus turbine windmill is also known as the eggbeater windmill since with its two or three blades it looked like an eggbeater.
  • The world’s first megawatt wind turbine which weighed 240 tons was built and connected to the power grid in Castleton, Vermont.
  • The popularity of wind energy has always been directly proportional to the supply and cost of fossil fuels. During the World War II when the price of fuel came down, the wind energy lost its popularity but again in 1970s when the price of oil skyrocketed , the interest and demand of wind generated power rose to a huge extent.
  • The demand and generation of wind energy increased more than fourfold between 2000 and 2006.
  • When it comes to wind energy capacity, Germany tops the list followed by Spain, the United States, India, and Denmark. It is also being estimated by the experts that if this pace continues, by 2050 one third of the world’s total electricity would be created by the wind energy.

We’ll be continuing with our series of interesting facts on wind energy. So, stay tuned to this space.

5 Important Facts About Wind Power

Posted on by Voltsys Team

It is being estimated by the experts across the world that by 2050 one third of the world’s electricity would be generated by wind power. This power generating source has many surprising aspects which everybody should know:

Use of wind power reduces Carbon dioxide content:

Use of wind energy reduces carbon dioxide production, and also, once constructed, uses no water for its generation and saves huge amounts of water. As per the report by National Renewable Energy Laboratory of US, every year 1MW of wind energy can reduce almost 2,600 tons of carbon dioxide production. The report also says that 1 MW of wind energy can save 1,293 million gallons of water!

The demand for Wind Energy is skyrocketing at an unbelievable rate:

The production of wind energy increased almost fourfold between 2000 and 2006 when the cost of fuel went up because of the unrest in oil producing areas of the world. Though production of wind energy involves a lot of investment to start with, it will surely reap rich benefits in the long run.

World’s Largest Wind Turbine:

Hawaii has the world’s largest wind turbine which has rotors as big as the length of a football field and stands 20- stories tall . One wind turbine can produce enough electricity to power up to 3000 homes.

Unpredictable Resource:

The raw material of this power i.e wind is quite unpredictable. When there is no force in the wind, the blades of the turbine do not move and thus there is no generation of power unlike the other resources where one can estimate how much power will be generated in a given time. However, if a grid extends over a large area, the average production across the region is much more stable, and wind can be a more reliable source of energy.

Minimal Maintenance Cost:

Once the turbines have been built and installed, there is no major intermittent costs to take care of. No extra fuel is burned to make the wind turbines work.
