You have heard the term biofuel but aren’t sure what it means. Biofuel is any fuel that is derived from biomass-recently living organisms or their metabolic by-products, such as manure from cows. It is considered ‘green’ because it comes from a renewable energy source, unlike other natural resources such as petroleum, coal and nuclear fuels.
Agricultural products specifically grown for use as biofuels include corn and soybeans (primarily in the United States) as well as flaxseed and rapeseed (primarily in Europe).
Waste from industry, agriculture, forestry and households can also be used to produce bioenergy and include straw, lumber, manure, sewage, garbage and food leftovers.

Over the past few decades, strains on the worldwide oil supply and the threat of global climate change have caused millions of people to alter their home energy habits. Thanks to modern science, there are now countless things we can do on an individual basis to help restore balance to the world’s energy systems.
But because these technologies vary in usefulness and are always developing, it can be hard to decide upon which option to use. After all, we don’t want to install a home energy system today that will be obsolete tomorrow. That’s why it’s important to stay up-to-date on the latest developments in green electricity for the home, and to invest in options that will be sustainable for years to come.

The need for alternative energy sources is nothing new but in this present time, the need is urgent on a global level. People and governments are reeling from the impact of the startling rise in energy costs and alarmed at the many dangers posed by environmental problems.
Across history, we have seen change in the kinds of energies used. As early as the 1200s, people swapped wood for coal as deforestation occurred locally. 300 years later, societies then depended on petroleum after depleting the supply of whale oil used to fuel lamps. In the early 1900s, corn-based ethanol oil supplied the demand for energy.

One hot summer afternoon, someone decided to test their craftsmen ship and take it upon themselves to make a homemade wind generator. It surprisingly took under $100 to make this wind generator. Although it does not work quite as well as a commercial bought generator and it would not hurt the design to have a few improvements.
If time is not a problem and you have a really flexible schedule then this could be something for you to try as well. However if you do not have a lot of time and have some expendable money then you can go buy a commercial generator prices vary and will save you a lot of time. However if you want to save yourself a couple of hundred dollars then try this out.

FAQ Wind Power
What is wind energy?
Wind energy is the use of the wind as an energy source. A wind energy system transforms the kinetic (moving) energy of the wind into mechanical or electrical energy that can be harnessed for practical use.
Mechanical energy: Wind energy can be harnessed by sails for transportation (sailboats) and other purposes such as grinding grain and pumping water. In the United States, some six million mechanical windmills were in operation in the late 1880s until about 1935, helping homesteaders and farmers to settle the West. Mechanical wind energy is most commonly used today for pumping water in rural or remote locations.
