Advantages and Disadvantages of Alternative Energy

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.

Top Five Things About Wind Energy

Here are the top five things you should know about wind energy.

1. Renewable energy source, which means that unlike fossil fuels can not be depleted. Until the earth and the sun will continue to wind blowing offer us valuable source of energy.

2. Environmentally friendly source of energy that is not linked to harmful emissions of carbon such as fossil fuels. Some environmental disadvantages of this renewable energy source noise (in some cases with extremely large wind turbines), and the threat to birds (if wind turbines are not connected with radar operations in the air in the holes).

3. In the last decade was the most popular renewable energy source, and the fastest growing renewable energy sector. This trend is likely to continue in the coming years mainly due to the rapid development of wind energy industry in China.

4. One of the most cost competitive renewable energy and wind turbines become cheaper almost every year. However, in the U.S. wind industry has been struggling somewhat lately, but because of low gas prices. This low gas prices are one of the main reasons why U.S. wind energy industry is very disappointing last quarter of 2010 had.

5. Wind industry currently faces two major obstacles that could delay some further development. These are not enough transmission lines and the intermittent problem because, as you all know wind is not blowing all the time. There are many ongoing scientific studies that attempt to provide adequate (cheap and efficient) wind energy storage option to develop the intermittent problem.

The Sun Is the Answer to Our Dwindling Energy Resources

It is only recently that people have begun to realize that there is a simple answer to the earth less and less energy reserves and at the same time allowing landlords and tenants to benefit from lower energy bills. The answer is the Sun!

There is enough energy in one hour Sun to supply electricity to supply the entire planet for one year. This fact has been known for some time, but the problem was always how we have to use power to sunbathe? Well, the answer comes through loud and clear in the form of solar PV.

Photovoltaic (PV) solar panels capture energy from the sun and converts it into energy. Solar PV panels can be installed on most roof spaces, provided that the area is large enough to approximately 12 panels and also the south of the sun to catch.Once installed solar panels last about 25 years and require virtually no maintenance, there are some solar installers also free annual checks and maintenance as part of their service.

In addition to the right of free electricity (when the sun shines!) Can the owner now also benefit financially by selling their electricity back to the grid. This is a fairly new system, but is a great way to earn extra money without extra effort. The only caveat with this system is that the panel installer MCS should be accredited. MCS is an administrative body similar to the will of Gas Safety and they check all the PV systems to ensure that high standards are maintained.

Once your solar panels are installed, the installer complete all the paperwork to ensure you earn your money back immediately. With the increased awareness being reported in the industry there is an increase in the reported investigations. This new initiative called Green Energy Cashback is definitely the answer to helping combat the assault on our energy reserves.
