When it comes to renewable energy sources, the first two that are predominately on the minds of many is the use of solar panels and wind turbines. For wind turbines, the principle is the same that you see in every gasoline guzzling car. Each of those vehicles are using an alternator to turn torque power into electric current to charge the battery. The wind turbine is no different. It is using the wind to turn the generator to produce large amounts of electricity in the same fashion as the automobile – minus the gas guzzling engine.
Depending on the area you live in, the wind may be constantly blowing. As there may be no resistance to hold the wind back, it is free to blow. Home-based wind turbines don’t have to stand at 200-feet in order to harness some of the wind that is blowing. As long as there is a deep cycle battery connected, any amount of wind could help reduce your energy expenses and could possibly remove your dependence from the grid. What are some of the features that are tied in to a wind turbine for residential and business locales?
1. Sizes – Various sizes are available for wind turbines, so you don’t have to assume it’s going to stand 200-feet tall with blades longer than your house. In fact, there are smaller units that can produce up to three kilowatts of energy from wind speeds of approximately 25 miles per hour that can fit in your garage next to your car. Devices like the Aleko WG3KW has a security feature that will throttle itself back at speeds of 40 mph in order to prevent damage from overcharge or burning the motor out.
2. Inexpensive – Compared to other renewable energy developments, wind power can be less expensive to produce similar results. For less than $2,000, you can assemble the small Aleko unit featured above and cover a large portion of your energy needs. Typically, a large family home could utilize 5,000 to 7,000 kilowatts of power requiring a few of these devices. However, the cost for implementing solar could be four to five times that amount if you installed it yourself.
3. Zero Emissions – The only source required by a wind turbine to generate power is wind. As there are no consumable fuels going into power generation, there are no emissions. The generator is simply powered by the wind spinning the blades of the unit. Although skeptics may point out that there are emissions being created by the vehicles used to ship the items, the point is moot. Unlike coal and oil based power plants, there are no other fuels being consumed to create energy. Tens of thousands of tons of coal are shipped annually to various power plants.
4. Combined Efforts – If you discover that a single unit isn’t supplying the power you need, additional units can be erected and tied into your power. This allows you to purchase turbines as you need them and not have to worry about coming up with a lot of money in order to be energy efficient.
Renewable energy sources are being developed and utilized all over the globe. What was once thought as a passing fancy has turned into a quest for continued efficiency. Whether you are a household of five or need to supply power to your business, wind turbines can offer an affordable solution to help reduce your bills and help conserve energy from the grid for other uses.
