The Advantages and Disadvantages of Alternative Energy

•An Introduction to Alternative Energy
What are fossil fuels? Essentially there are three fossil fuel sources available to the world but each of them are dwindling. The most abundant is coal; coal is widely used and inexpensively extracted. As such, we have come to rely exceptionally heavily on coal and while there is still quite a large amount of coal left it is estimated that America's remaining coal will sustain the country for the next 200 too 300 years but it is by no means a perfectly clean form of power. The biggest...

•An Introduction to Hydro Energy
What is hydro energy? Fossil fuel reserves have become seriously depleted but conversely our energy use is increasing year on year, our fossil fuel use is now far from being sustainable. Fossil fuels are also responsible for global warming because of the carbon dioxide that is produced with the use of coal power stations and other fossil fuel power stations. In order to stop a further decline in the environment and to replace non-renewable energy many different alternative power sources are...

•About solar energy panels
What is a solar energy panel? A solar energy panel collects energy from the sunlight and converts it into direct current (DC) electricity. Two oppositely charged slices of silicon are placed together below a piece of glass and as the protons in the sunlight knock the negatively charged neutrons away from the silicon the electric field created by the two adjoining pieces of silicon attract the neutron. Small pieces of wire catch the neutrons and when they connect they create direct current...

•Wind Energy Systems for the Home
Is it possible to power a home using wind energy? In theory it is possible to become energy self-sufficient relying on purely wind energy to power your home, but in practise the situation is somewhat different. You may find that unless you have a small house, a large patch of land and forgiving neighbors it is very unlikely that you will become self sufficient off the back of wind energy alone. Most houses would take up to a dozen wind turbines to power their house but by combining wind...

•Hydro Energy for the Home
Can I really use hydro energy to power my home? There are really very few people who would be able to take advantage of hydropower in their homes. A small stream simply isn't going to be big enough to power even a micro hydro energy system but if you happen to be one of the very lucky few who have a reasonable size stream or waterway of any sort running through your land then hydro power is an excellent form of power and you should consider looking into it. It has one big advantage over any...

•An Introduction to Wind Energy
About wind energy? Put simply, wind energy is energy derived from the wind. By using wind turbines we are able to harness the power of the wind and convert it into electricity for use in homes, schools, businesses and any other establishments that require electricity. Originally it was thought inconceivable that we would be able to use wind turbines for anything other than milling flour but this theory has been proven to be very wrong. Our search for renewable sources of energy has led us...

•How Does Solar Power Work
The basics of solar power. Solar power is probably the cleanest, most viable form of renewable energy available and it can be used in several forms to help power your house. Many gardens now use solar lights or solar garden water features. The availability and wide use of solar power in gardens shows exactly how versatile it is as a source of energy. The technology and the systems are becoming smaller, more compact and better looking than when they were first created and used. Early examples...

•What is Diabetes
Diabetes is a disorder of metabolism the way our bodies use digested food for growth and energy. Most of the food we eat is broken down into glucose, the form of sugar in the blood. Glucose is the main source of fuel for the body. Diabetes causes glucose to back up in the bloodstream. As more and more glucose remains in the bloodstream blood glucose or blood sugar levels can rise too high. There are two major types of diabetes. Consider the following information a s it relates to both type...
