Residential Windmills Are They Useful?
Thousands of people all over the world are increasingly picking interest in renewable energy. Besides being
clean, renewable energy offers numerous financial benefits, mostly through rebates and other schemes offering
incentives to homeowners producing their own diy energy.
Residential windmills have been a major subject of discussion during the last couple of years. It is very
refreshing to think of a power source that’s not only sustainable but economical too.
Many people have found windmills to be useful and many more are considering installing a windmill at their
Having said that, it’s not all rosy with windmills; there are a few pitfalls as well. For instance, installing a
windmill for a commercial setup may not make much economic sense since typical turbines generate minimal amounts of
To generate larger amounts, you would need to invest a hefty amount to get turbines with bigger capacity –
meaning you’d have to wait for years to realize returns – or you would need to complement your power generation
with another source, such as solar. Windmills are usually installed at settings with smaller power needs, like on
farms to power water pumps and other small electrical appliances.
How a residential windmill works
A windmill consists of a generator, with a shaft attaching to it. The shaft is also attached to 3 blades that
collect wind when it flows over them. When the blades gather this kinetic energy from the wind, they rotate but
with little force. Much of the force is passed on to the gearbox through the shaft.
The gearbox then adjusts this force and instead of rotating at a slow speed with more force in each revolution,
it rotates faster with less force. The generator – attached to the gearbox - will then convert that kinetic force
into electricity using the magnetic field and copper wiring inside. The electricity is then stored in a
The output of a windmill depends on the speed of wind. Higher windmill altitudes achieve greater wind speeds and
therefore greater outputs. In addition, windmills at higher altitudes are less noisy.
The merits of residential windmills
• Consumers stand to gain a lot when they install a residential windmill.
• One of the obvious benefits is that a residential windmill is very eco-friendly. In the age greenhouse
emissions and environmental degradation, alternative sources are a breath of fresh air.
• When you install a windmill, you can expect a huge chunk of your energy bills to be slashed. Depending on
how much wind energy you generate for your home power needs, you can save up to 50 percent a year in energy
• You may also be eligible for a number of federal tax credits, as well as state and utility rebates and
incentives programs. About 42 states operate a net-metering system, which can literally wipe out your bill, or even
get paid by the utility when you have excess power generated.
• An alternative power source cushions you against unforeseen utility outages and other uncertainties.
• Windmills are the energy alternative of choice in rural areas, not just for farms but for residences
While residential windmills are certainly useful, affordability still remains a huge concern for many people.
Initial installation costs are still on the high end for many, and maintenance is not cheap either. Still, wind
energy costs have drastically gone down in the last decade, so hopefully, the trend will continue in that
