The concept of wind energy is not a new one, in fact, wind generated power has been employed for centuries. Wind holds much potential in accomplishing the goal of clean energy. The wind is used to accomplish tasks every day, and if it can be adequately and cost effectively harnessed, it could eventually be used to wean ourselves from polluting, expensive energy sources that are damaging to the environment. Wind energy is renewable and non-polluting. Now, it is time to focus on finding a good, reliable method of storing this energy source.
Wind Energy Storage Pros
Wind energy is fairly simple to harness, it takes a turbine that catches the wind and then spins, creating energy. The spinning turbine’s created energy is then funneled to a battery pack, then to a charge inverter where the energy is changed from DC to AC and is available for use to run the lights, the television, or other items that require electricity.
Wind energy systems are lower cost to manufacture and operate making them slightly more attractive than a solar photovoltaic system which involves high start up and installation costs.
Wind energy systems are easier to operate, making them a good choice for the private homeowner who wants to reduce or eliminate his dependence on the utility companies for his power needs. There are not a lot of technical terms or parts to know or understand with the wind energy systems and there is no fiddling with controls to try to maximize power output.
Wind Energy Cons
The wind is not predictable nor is it always reliable. There are times when the wind is not blowing at all. This creates problems for those who rely on it for energy. The wind is influenced by the temperature of the earth. There is more wind at cooler temperatures, so, in general, there is more wind at night than in the daytime.
Wind energy storage is noisy, especially on the large wind farms that are being built for bigger energy usage.
Wind farms are also deemed dangerous to local bird life. This has sparked protests in some cases as hundreds of birds have perished in the turbines.
Although they are not expensive to build or to operate, the wind systems have issues with reliability, mainly from air flow, but occasionally from mechanical failure as well. Issues with controllers and other moving part components are also problematic at this point.
