Lower Your Electricity Bills With Home Wind Energy

Thursday, October 22nd, 2009

With many contraptions and inventions popping up in all four corners of the earth, the best thus far is the home wind energy.

How Do These Home Energy Turbines Work?

The home wind energy turbine, placed typically at home on a prop or tower, gathers kinetic energy (energy resulting from an object’s motion) from the wind and converts to electricity that matches with your home’s electrical system.

For normal home use, the home wind energy serves up simultaneously by the wind turbine  to a local convenience for the hose hold gear. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine supplying home wind energy. All of the needed power is purchased from the utility.

The output of the home wind energy turbine is enhanced as the speed of the wind increases, while the power output is decreased proportionately. When the home wind energy turbine produces more power than the house needs, the extra electricity is sold to the utility. This is all done automatically. There are no batteries in a modern home wind energy generator.

How Does The System Save Money?

The home wind energy turbine typically lowers your electricity bill by 50 to 90 percent, and has a potential to lower electric bills to a monthly average of $10 to $20 for the year. The amount of money a small home wind energy turbine saves you in the long run will depend upon its cost, the amount of electricity you use, the average wind speed at your site, and other factors.

Before the installation of a home wind energy system, here is what you should consider? If you own a home in an urban area, having a home wind energy system is most likely not feasible becuase of its size. With the exception of the very small home wind energy turbines, which requires a property size of approximately one acre or more.

The financial side of a home wind energy system is very sensitive to the average wind speed in the area, and to a lesser extent, the cost of purchasing electricity. As a general rule of thumb, at an average of 10 mph wind speed one will be paying about 10 cents/kWh for electricity. Home wind energy systems are quite common in a number of states.

The Environmental Impact Of Using A Home Wind Energy System

Home wind energy turbines produce no pollution. Over its life, a small home wind energy turbine can offset approximately 1.2 tons of air pollutants and 200 tons of greenhouse gases (carbon dioxide and other gases which cause climate change). And as a bonus, the home wind energy system does not require regular maintenance as they are generally designed to have a life span of 20 years

Should you then need to consider an earth friendly way to generate electricity at a small scale, you might need to consider this system.

Earth4energy – Learn How to Build Solar Panels

Friday, August 28th, 2009

The Earth4Energy manual is a great step-by-step guide for anyone wanting to build their own solar or wind power generator. The decision to use solar or wind power for an alternative energy source is not only great for the environment, it’s also very good for your wallet. Let me explain.

The first homemade solar panel I built was a portable solar power system for just under $200. You know, when I started building renewable energy sources I did it because of curiosity. I had heard that many people managed to create energy-generating devices, so I thought I will manage to do them to. When I found information about earth4energy and its videos I had no doubts that this is what I need.

The guide contains so many different solar panels blueprint, personally I used only portable solar panel, however if you want for example a grid-intertied panel you will find how to build it there. You know, the most powerful setup is undoubtedly an off-grid setup, it can generate electricity fo your entire house and sometimes even give electricity to your neighbours. But what about the price of the materials?

Believe it or not, but if you have enough materials in your household, you will spend $0 to build a solar panel. Some of the required materials are very easy-to-find, moreover, we use some of them every week.

The whole guide is not only about building solar panels, it will also show you how to build wind turbines. Believe it or not, but a small turbine could cost less than one hundred dollars, you know, they are ten times as expensive in shops. However, the problem is that it is impossible to generate electricity if you do not have enough wind in your country. A basic rule is that you want the average wind speed in the area to be around 10mph for the unit to be cost effective.

If you really want to build a wind turbine or a solar panel to generate electricity, earth4energy is undoubtedly what you need. How do windmills work
