Wind turbines convert the kinetic energy in the wind into mechanical power, which can be used for specific tasks like pumping water, or a generator can convert this mechanical power into electricity to power homes, businesses or schools.
Here are a few wind energy facts that you may or may not know. Too often people forget that wind energy might be a potential alternative source of energy. Here's why wind power should not be overlooked:
- Wind energy is a form of solar energy, and is therefore renewable.
- Wind does not need to be produced, like ethanol does, therefore there will always be a constant supply of it.
- Wind energy is very expensive to set up. It requires significant amounts of capital to establish wind farms. After the initial investment and startup costs, however, it is one of the cheapest forms of electricity generation to maintain.
What we are starting to see is through these wind energy facts is that we have not taken wind energy seriously enough. There is an incredible amount of energy that can be generated through the power of wind. Until we realize just how awesome this energy source is, we will be left to worry about rising fuel costs and the problems that fossil fuels create for humans, animals, and the environment. Let's hope that wind energy is taken more seriously on a global scale.
