The world’s supply of fossil fuels such as coal and oil is rapidly depleting. At the same time, we are becoming more aware of the large toll that the use of these fossil fuels is taking on our environment. As a result, the need for environmentally friendly, renewable power sources becomes more evident every day. One of the most exciting and widely used forms of alternate energy is hydroelectric power. A pivotal improvement in hydroelectric technology came in the form of the Pelton wheel. The Pelton wheel revolutionized hydroelectric power generation by offering a highly efficient and innovative design.
With the upcoming increase in electricity rates and the green movement pushing alternative energy sources, the solar power industry has become a booming business. Many people are considering solar power as a way to break free of the conventions and whims of their electric company and be self sufficient when it comes to powering their home.
However, you don’t have to go completely off the grid to power your home with solar energy. In fact, most people who install a solar power system will stay tied to their electric company’s grid as a precautionary back up system.
As the world’s energy consumption explodes, no one can argue that there is a growing need to find an alternative to fossil fuels. Among the renewable resources being investigated and implemented is hydroelectric power. Hydroelectric power, generated through hydroelectric turbines, has proven to be a clean, viable renewable resource with many benefits. In addition to large scale industrial use, micro hydroelectric turbines can be easily added to a home power system with great results.
Your attic can often reach temperatures of more than 150 degrees in the summertime, and no matter how well your attic is insulated, some of that heat is bound to seep through vents or cracks in your attic and enter your home. A solar powered attic fan is a type of active ventilation that pushes the hot air out of your attic, reducing the heat stored there and cooling the attic by up to 10 degrees! This article discuss how you can use a solar powered attic fan to cool your attic, lower your electric bill, and keep your attic free of dangerous mold.
Solar panels are very popular in generating electricity. These photovoltaic cells convert energy from sun to electricity. Traditional solar cells had their own share of problems. People had to keep them clean and they were heavy and bulky making it hard to maintain. They did not look nice on your roof. But solar singles changed all these. These are thin flexible panels installed on your roof top. They are not heavy and practically invisible. They can cover larger area of your roof, and generates more electricity. But they have some disadvantages as well. Read On for more information on solar shingles.
There are different types of processors to make biodiesel. Among them are two main different types. They are continuous type and the batch type. Continuous type biodiesel processors are mainly used in commercial scale, while batch processors are used in small scale home production. There are different types of these batch processors with their unique advantages and disadvantages. Some popular types are Appleseed processor and Touchless Biodiesel Processor. Read On..
Earth4Energy guide by Michel Harvey is very popular among renewable energy enthusiasts. This shows how you can build a solar and wind power system for fraction of the cost they are sold for. But some claimed this guide is not useful and some claimed this is a fraud. We thought about doing the research ourselves. So we started by purchasing the product. Then we discussed every point both negative and positive for their accuracy. At the end of the review you can see a small trick which will help you to save some money if you decide to buy the guide.
Wind is a very popular source of alternative energy. Unlike solar, a properly setup wind turbine will generate electricity throughout the day, day and night for years to come. You can save at least 80% of your energy bill with a wind power system. But if you are a victim of the myths created around generating residential wind power, you might end up losing money instead of saving. 5 Biggest myths associated with residential wind power are listed below. Before you start your project check whether you are a victim of any of these myths. Otherwise it will be too late.
Helical wind turbine is a type of vertical axis wind turbines (VAWT). Main feature of this type is its helically shaped wind blades which can turn the turbine even in small winds. Its ability to run even in small winds, and its ability to place relatively in a lower position, makes it the ideal solution for residential wind power. When placed on a roof top helical turbine can produce nice amount of electricity. Helical wind turbines are gaining in popularity worldwide. Read More… (Click on the Title)
The Darrieus Turbine dates back to 1927, when French aeronautical engineer Georges Jean Marie Darrieus patented this innovative turbine design. The Darrieus Wind Turbine resembles a gigantic eggbeater and has two main advantages. The first main advantage is that the equipment including the gear box and the generator can be placed close to the ground. The second advantage to this type of wind turbine is that you don't need a new mechanism to turn the rotor against the wind
