Wind power

Wind power is so easy to produce from simple wind power stations. These wind power stations can be homely ones, which you can install on your private roof to try to catch some wind. The other side of the wind power stations kinds, are the massive ones you can see on the open fields of many countries around the world, each wind turbine like that reaches to the height of 100m!

For home use, you will need simple wind turbine, connected to wind power station, to produce home use power. The location of the wind turbine, the highest to locate it, the correct direction it to and the right size of the turbine blades are all parameters to consider in order catching the maximum wind power. Open fields, down hills and clean airflow locations are the best places to calculate the maximum wind speed cube for producing wind power. For example, out of a win which blows for 30 Km/H you will be able to produce 300W ( per one square meter cube ). Double of this wind speed will generate much more than double power, something like 2600 Km/H. This is why on windy areas and on high potential locations for windy days, wind power stations are the most green and economical solution.

Home installed wind power stations must have stable wind. If the wind flow is much disturbs, the efficiently of the wind power productions reduce dramatically. This is why you will always see the wind turbines in open area's or high on the top roofs. Comparing to solar panels, wind stations are much costly but also much more efficient. Over the years, you will be able to produce more energy and maintain the power station less than with solar panels. Same like solar systems, the wind systems usually charge large batteries for later use.

There are some advanced solutions to produce wind and solar energy together. The solar part of the system makes sure that the complete system will produce power in no wind days and the wind turbines are taking care of the no sun days. In totally, the system produced alternative power energy, green energy.resources:www.powersavingsystem.com

Greenhouse Gases

Greenhouse gases are naturally found in air. They include carbon dioxide, methane and nitrous oxide. They trap heat in the atmosphere and keep the Earth's surface much warmer than it would be if there was no atmosphere. This warming effect is called the natural greenhouse effect. In the last 200 years, the amount of greenhouse gases in the air has been increasing, due to human activities. Mankind has been increasing the amount of carbon dioxide, methane and nitrous oxide in the air, and has even been adding completely new greenhouse gases to the atmosphere, like the CFCs, which also destroy the ozone layer.

Carbon dioxide is produced naturally through when animals breathe, when dead plants and animals decay, and during natural forest fires. Mankind produces carbon dioxide when coal, oil and gas (the fossil fuels) are burnt for energy and electricity, and when forests are cut down or burnt to make way for agriculture. Trees help to remove carbon dioxide from the atmosphere by using it to make food (photosynthesis). Plant life in the oceans also uses carbon dioxide. Methane is another major greenhouse gas. It is formed naturally in marshes and bogs when dead plant and animal matter decays, and also by termites. Mankind releases methane by growing rice, farming cattle, burying waste and burning fossil fuels. Nitrous oxide is a greenhouse gas naturally produced by oceans and by lightening strikes, but humans have increased the amount in air by the production of nylon and through using agricultural fertilisers. CFCs (chlorofluorocarbons) are a group of man-made substances containing chlorine, fluorine and carbon. They were invented in the 1930s for use in fridges, but have other uses, including aerosols. They are very strong greenhouse gases and remain for a long time in the atmosphere. They break down at high altitudes where they contribute to the destruction of the ozone layer. Fortunately, their use has been banned since 1995.
