The alternative energy sources that we use are crucial to the survival of our world. Natural resources such as wind and solar are not for sale, but it is his armor. The wind is the force behind turning windmills for years. Turbine blades, which are part of the windmill functionality, depend entirely on the effectiveness of the wind. The biggest drawback to owning a wind turbine is not enough natural wind going. Of course, another drawback is that birds tend to fly right in the magazines, which of course is disastrous for them.Wind energy gets fuel from nature and is safe for the environment.It takes less than 5 cents per kilowatt use of wind resources.

Of all the alternative energy solar energy is undoubtedly the most popular. The many advantages to using solar energy are phenomenal. Homes, offices and schools benefit from the use of solar energy panels, and lighting. Of course, hot water is heated naturally without the use of electricity. Other useful features such as calculators and alarm clocks all receive their energy from stored heat. The disadvantages of using solar energy can only armor on sunny days, and not on rainy or cloudy days. Since the solar light can only be collected during the day. This is why greenhouses are excellent candidates for solar light energy.

The biggest drawback is cost. It cost more than $ 10,000 for solar panels provide a whole house. This is not an inexpensive project, but in the end, it will pay for itself. Solar energy can eliminate an electric bill, or drastically reducing the amount of the monthly invoice. Hydro-electric energy is also another form of energy based on water consumption disadvantage is it’s not very safe for fish or other vertebrates.
