Solar radiation hits the surface of the planet Earth. In turn, the surface heats the air above it. Air that is heated rises in the atmosphere. It also picks up moisture, which rises with the warm air. As earth spins, air movements generate a complex system of wins. In essence, wins hold solar energy, which we can capture with windmills.
When this energy is harnessed by windmills, it can be converted into electrical energy which can flow to homes and businesses in the nearby area. This electricity is a form of clean, renewable electricity that can be used to power electrical devices, charge phones, cook food, heat water and light up rooms. Ballarat electricians are qualified to work with this electricity to safely power your computers, fridges, TVs and light up your house.
The idea of using wind power to generate electricity has been around since 19th century, but until the 1980s it was too costly. By 2010 wind turbines were being installed in Europe and the United States at a furious pace. Denmark supplies about 20% of its electricity needs from wind. Germany produce the most electricity from wind, the United States produces the second most. Wind power is growing at almost 30% per year. New materials and technology have lower the cost of collecting wind energy, while other more traditional forms of energy costs have increased.
Wind turbines turn when they are bumped by fast moving molecules of air. As each molecule hits the blade of a wind turbines, it gives the blade some of its energy. The turbine blades speeds up in the air molecule slows down. The fast the wind blows, the faster it can spin the turbine blades. What’s really impressive is that if the wind speed doubles from 10 to 20 km/h, the potential power it can deliver to the turbine doesn’t just double it increases eightfold. Part of the challenge with wind power is finding areas that have consistently strong winds. If the wind is in blowing the windmills don’t turn and they don’t produce energy.
Wind power is a form of renewable energy. It is energy that comes from sources that are naturally replenished in short periods of time. Wind energy production is growing rapidly throughout the world and especially in the United States, stop wind is ultimately a form of solar energy as mentioned above, stop the air moves in patterns that control climate and weather. Wind turbines can be used to capture wind energy and converted into electrical energy nearly as cheaply as energy is made by burning coal.
