The Greener Power – Wind Power Electricity
By: Bruce Partridge
There are different sources of electricity. Most of our electricity today comes from power plants in which power generators are fueled by things like coal and petroleum. Alternatives like solar power and wind power are available as well and increasing in popularity due to the fact they are known as clean and renewable sources. The different sources of energy fit the different needs of the consumers. Each energy source has its own advantages and disadvantages that may determine its availability and feasibility in any given application.
Electric power from wind is an example of clean energy. When generating electricity from wind, there are no harmful chemicals or gases emitted during the process. As a matter of fact, most environmentalists push for the implementation of more wind turbines to power communities and provide them with their basic need for electricity. Just imagine a world with clean sources of energy: it would be wind-powered, smokeless, odorless, and environmentally friendly.
To understand the basic operation of converting wind to electricity, one needs to understand the generator itself. A generator is an electrical machine that converts kinetic energy to electrical energy. There are a lot of articles on the internet that discuss in detail how they operate. As an electric generator, it needs a “prime mover” in order to operate and produce electricity. The prime mover is actually any mechanical force that rotates a certain part of the generator. There was a period in history when people manually rotated the generator for power production. This of course was very impractical. We need other sources of mechanical force to act as the prime mover of the generator. In the mid 1900′s, engineers began to design generators with wind as their prime movers. Later in 1970′s, the first practical wind powered generator was in operation, and so began the era of wind-powered electricity.
Wind power generation is most ideally located where there is a strong wind almost all the day, every day. The most common locations are beaches and coastal areas where there is a sea breeze during the daytime and land breeze during the night time. With enough wind power, electricity generation can go as high as several kilowatts to megawatts, enough to provide power to a small to medium sized community. Islands with wind generators located on the mainland can provide their own power. Submarine power cables are very impractical and dangerous at the same time. So by using wind energy, the island can still have electricity. Archipelagoes will benefit this kind of electric power generation.
There are many advantages that wind energy offers. It answers both the problems of decreasing sources of fossil fuels and the need for a clean energy sources. For years, it remained a minority in providing electric power to communities, but as technology and the demand for clean, renewable energy sources increase, we will likely find it used more and more.

How to Build Biogas Methane Generator at Home
By: Susan Smith
Using biogas methane is a very good idea.It is good for us and for the environment.Biogas methane is a mixture of gas includes carbon dioxide and methane. It is produced by the biological breakdown of organic matter with the absence of oxygen. Biogas can be used as cooking gas. It is very clean and is very environmentally friendly. The bio-gas is obtained from plant, animal and human waste, also called as biomass. The main source of biogas methane is wet cow dung, which is most commonly used for production of biogas. The other materials used to make biogas are: sewage, crop residue, vegetable wastes, waste wood, dry leaves of the plants, broken branches of trees, garbage, waste paper, poultry droppings, pig manures, algae, ocean kelp etc.
Biogas methane can be produced utilizing small plants which is called biogas generators or biogas plants. These plants are fed with biomass. During the process, an air-tight tank turns the waste into methane. The various chemical processes that can be used for production of biogas in biogas plants are: digestion, Pyrolysis and hydrogasification. There are many types of biogas plants. To use which type of them depends on the biomass type and the quantity of gas to be produced.
To make biogas methane at home, it is better to use food waste. Animal waste is difficult to handle and the smell is very unpleasant. Food waste is much easier to handle with. And the biogas generator for food waste is small and convenient to use. You can easily build it yourself instead of buying one.

Solar Energy for Homes – Using Solar Panels
By: Adam Sorenson
Using solar energy for homes has its own benefits. After the recession when many homeowners have felt the impact of not being able to pay for their electricity bills, who wouldn’t like the idea of saving some money? Which brings me to my next question, who wouldn’t want to save on monthly electrical bills? Well, the answer to all that is through using solar panels.
For those of you, who don’t know the slightest idea on how to use solar panels for your house, don’t have to fret. In this article I will be talking about how you can use solar energy for your homes effectively. To start off with, you need to know how much requirement you need for your house. Before that, you will need to have a good idea on your surroundings.
If you are living in a hilly and heavily forested area, then I’m afraid you might not be able to use solar power very effectively. If your place doesn’t have sun light all through the year, then that also can be a problem. Of course, the sun doesn’t shine throughout the whole year, but you can still make use of the electricity which comes from the solar power systems.
Using solar energy for homes is a very wise idea as you simply collect the sun rays and then convert it to electricity by using solar panels. With this you are saving about 80% on your electricity bills every month. Doesn’t that sound great? However, there is no need to cut off your existing power supply. It is not a very expensive and tedious process to build a solar power system for your house.
There are lots of sources online from which you can information on DIY solar kits. They also come with step by step instructions on how to develop homemade solar panels. They are easy to understand as the instruction material provides diagrams also which are easy to read. A word of caution though, if you are not good in electronic terms and don’t have an idea on what’s going on, it would be wise to use an electrician.
The solar panels usually don’t have high volts, but your electronic grid has and it is the best option here as you don’t want any accidents. Using solar panels are not expensive as you will need to make a small investment to enjoy an unlimited source of renewable energy. It is important that you place the solar panels where there is plenty of sunlight. It can be either placed on the roof or an open space where you get ample light.
If you can afford ready made panels of $3,000, then go ahead or you can also utilize the DIY solar panel kits that come at only $200. Make sure to select a solar power system that is required by you. You can start of with a small system and later move on with a larger system.
You will be pleased to know that you will be saving almost 80% on your monthly electricity bills. If you are residing in a place where there is lots of sunshine, then you can benefit by building your solar panels.
