As modern society searches around for alternative energy sources, wind farms are getting mention. There are, however, limitations regarding wind farms as major energy alternatives.

Wind Farms – Limitations as Energy Platforms

Wind power is an enticing energy platform compared to fossil fuels. The process works by using the inherent energy in wind as a method for producing electricity. The actual methodology is much like hydropower, but with wind used in place of water. Wind turbines catch the wind, which turns their blades. This turning motion cranks a generator that produces electricity. The electricity is stored in batteries or fed into the electrical grid of a utility. Walla, you have power!

Using wind power for localized needs has been around for a long time. The Persians are believed to be the first to use it with the purpose being to turn grain grinding stones.

In modern times, the sole purpose is to generate electricity. On a large scale, this means wind farms.

Wind farms are simply large collections of wind turbines in a defined area. If you have ever driven east out of San Francisco, you have seen the wind farm along the freeway. While it is both intoxicating and a pollution free source of electricity, a wind farm has definite limitations.

The biggest limitation of wind farms is the electricity produced. Simply put, they do not produce massive amounts, certainly not on the scale needed in most cities in industrialized nations. Obviously, each location is different, but wind is simply not a constant occurrence in most places. Even when it is, the number of turbines required to produce enough energy for a city is mind boggling. This, of course, leads to a second limitation.

Wind farms need to cover a lot of physical space to produce large amounts of electricity. In many industrialized countries, space is at a premium. As a result, the sheer cost of purchasing land for wind farms is prohibitive. This issue, however, is losing some of its grit as offshore wind farms are becoming more prevalent.

To some, one of the limitations of wind farms is they are eyesores. Personally, I think they are mesmerizing and have an artistic appearance. Others, however, definitely do not agree. The Cape Wind offshore wind farm project has met with massive resistance for just this reason.

The limitations of wind farms are fairly significant at this point in time. As technology and new approaches, such as offshore wind farms, come to the forefront, these problems may fall the wayside.

Are you interested to learn how to build a solar and alternate energy system at home? One of the technologies that really interested me was solar powered electricity systems, which seemed like a really good solution for me since there is a lot of sunlight around my house every day.

1. How Does a Solar and Alternate Energy System Work?

After researching on the Internet and downloading several guides about renewable energy technology, I found out that there are actually quite a few methods that can be used to harness solar power from the sun. One of the best types is to harness photovoltaic solar energy.

This form of power has actually been in used by many types of small household appliances such as calculators and lights. With the advancements in technology, it is now completely possible to convert sunlight into photovoltaic energy which goes a conversion step to become electricity that can be used to run a home.

2. Harnessing Solar Energy Indirectly to Power Your Home

Another method is to harness solar heat through special windows. The windows are able to transfer and contain heat within the home that can be used passively for other purposes like heating the home. To be able to use this method, your house must be fairly air tight and be properly insulated.

3. What are the Advantages of Running Your Home with Solar Power?

Converting solar energy into electricity is a very simple and inexpensive process. On top of that, solar power is completely free and can be converted very easily with simple systems. Besides electricity production, it can also be used for heating purposes to heat water and air in a house.

With the economy the way it is today, a lot of people are trying to find alternative ways to save money on their bills. Green energy is a growing field because of all of the ways you can make your own power instead of relying on your local power company and that will be a great feeling that you can be self sufficient.

There are many ways to produce power for your home and here are a few ways you can do just that.

One way is to make a solar panel so you can harness the energy that is coming from the sun. The warmth of the suns rays can be put to good use if you build a solar panel. The cells in the panel turn the suns rays into power that can be used in powering your whole house and you can also use the sun for heating your own water to eliminate the use of your hot water heater cutting the power you are using from day to day down even further.

Windmills can also make power for your house by using the wind that turns a turbine to create power. The one problem with the windmills is that if there is no wind, the blades on the windmill won’t turn to create the power you need. When you are using a windmill to produce power for your home, the windmill stores energy in batteries just in case there is no wind for a day or some. The batteries are big and you need an area to store them out of the weather.

Another way you can make your own power is to make a dam or hydroelectric power. In order for you to use this option you need a river or some type of moving water on your property in order to create the power you need for your house. This way is the most economic way to create your power for your house because all you need to do is make a dam. You can find the plans you need to build this dam online and the materials are very inexpensive.

All of the ways to produce green energy, you can find plans and a list of materials online and you can find the materials you need in your own back yard or in the local junkyards. You can build all of these devices for less than $ 200 or less depending on where you get your materials from.
