Uses Of Wind Energy

Carol asks…

Why don’t people use more wind energy?

Read the question.

Hey Dnoh, I think by reading quickly down this list of answers, you should be able to answer your own question. There are a lot of facts about wind energy, such as the cost of producing the equipment, the grid requirements to move the energy to where the loads are, the noise they might create and so on. What exists in larger quantities is the misinformation about all these facts. One fact that is obvious if you travel around is that wind power is expanding very quickly, and it isn’t happening because it is expensive, inconvenient or not beneficial, quite the contrary. The new turbines today in the United States produce power for less than 5 cents per kilowatthour, that’s a little less than many of our traditional sources, and about even with coal power. Most people believe that traditional energy sources will become more expensive in the future as the price of oil goes up, and rightly so. So as the price of wind power comes down, it becomes even more attractive. For this reason, many companies are manufacturing and installing utility sized wind plants as fast as they can. On a flight from coast to coast today, you will pass within viewing distance of 8 wind farms on average. Ten years ago it was less than 1. So more people are using wind power, they just don’t realize it.

As far as home systems, we have been powering our home from the wind and sun for almost 10 years now, and our system, which consists of a 1.4 kw solar array and a 1kw wind turbine, including the batteries, charge controllers, inverter and other electronics, cost less than $15,000. Subtract off the amount of money we received in grants and tax incentives, plus the small amount we receive each year for selling carbon credits to industry, and we have spent less than $10,000 on our equipment. It produces about $30 of electricity each month, so it might take a generation to get the money back, but that is not why we got involved. It makes sense to us environmentally to make our own energy, much like a homeowner might grow their own tomatoes even though it’s cheaper to buy them at the grocery. There is also the fact that the power never goes out at our house, something that is difficult to put a price tag on.

Wind energy today is like the cigarettes of yesterday. It wasn’t long ago when people still argued about whether or not they were bad for our health. Try making that argument today. I hope that in another 20 years we won’t have to ask questions like yours, only time will tell. If you want to learn more, here are some sources. Take care, Rudydoo

Donald asks…

What are some of examples how wind energy is currently used?

For examples

Windmills
Sailboats
To generate electricity

I need more though, so give me as many as you can think of

Windmill Farms answers:

Propel sailboats and sailing ships.
Architects have used wind-driven natural ventilation in buildings.
Irrigation pumping and for milling grain.
The “water-pumping windmill”.
Pumping water from water wells for the steam locomotives.
Small wind machines provided electricity to isolated farms.
Wind turbines to generate electricity, which was then used to produce hydrogen.
Small wind turbines for lighting of isolated rural buildings.
Use wind turbines to displace diesel fuel consumption.

Wind turbines have been used for household electricity generation in conjunction with battery storage

The surplus power produced by domestic microgenerators can, in some jurisdictions, be fed back into the network and sold back to the utility company, producing a retail credit for the consumer to offset their energy costs.

Wind power consumes no fuel, and emits no air pollution.

George asks…

how do winds energy work? explain please?

how do winds energy work?

Windmill Farms answers:

Wind energy just uses the wind and giant turbines

when the turbine moves it then generates electricity which is stored or distributed.

Robert asks…

is it easy to pump water than producing electricity by using wind energy?

Windmill Farms answers:

These are two different but related topics. One thing our electrical grids generally lack is any form of energy storage. Uhfortunately our electrical usage is not constant and we have to build enough generating capacity for peak power demands. Energy storage might allow us to use off peak generating capacity to provide peak power. One of the only ways we store energy is by pumping water to a higher elevation and then generating power as it falls. While the process is reasonably efficient the energy density is often low.1

While pumping water is reasonably certain, electricity that can be made from wind is less so. One idea is to store the power of the wind in hydro pumping facility to produce a predictable capacity on demand.

Both type of facilities require the right kind of location. Current economics seems to favor more wind generation over hydro energy storage facilities.

William asks…

do we use energy wind in connecticut?

Windmill Farms answers:

Wind is simple air in motion. It is caused by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of very different types of land and water, it absorbs the sun’s heat at different rates.

During the day, the air above the land heats up more quickly than the air over water. The warm air over the land expands and rises, and the heavier, cooler air rushes in to take its place, creating winds. At night, the winds are reversed because the air cools more rapidly over land than over water.

In the same way, the large atmospheric winds that circle the earth are created because the land near the earth’s equator is heated more by the sun than the land near the North and South Poles.

Today, wind energy is mainly used to generate electricity. Wind is called a renewable energy source because the wind will blow as long as the sun shines.

As part of its 1998 Electric Restructuring Public Act 98-28, the Connecticut Legislature requires all investor-owned utilities to provide net metering to residential customers who own electrical generators using Class I renewable resources, including wind power.

Net metering provisions in utility tariffs approved by the Connecticut Department of Public Utility Control (DPUC) established the maximum system size limit for net-metered renewables at 100 kW. There is no limit on the total net-metered capacity.

Although distribution companies are required to offer net metering only to residential customers, Connecticut Light & Power Company (CL&P) and the United Illuminating Company (UI) do make it available for businesses under specific conditions.

Net excess generation is purchased at the spot market energy rate, which is essentially the short-term avoided cost (less than retail).

As of 2003, only net-metered customers with systems greater than 10 kW can be charged for the competitive transition assessment and the systems benefits charge. These charges are based on the amount of energy consumed by the customer from the facilities of the electric distribution company without netting any electricity produced by the customer
