The Power Wind: is renewable and doesn' t produce gases during operation.
Airflows can be used to run turbines.since wind speed isn't constant, a wind farm's annual energy production is never as much as the sum of the generator nameplate ratings multiplied by the total hours in a year.

Renewable energy

Renewable energy is energy generated from natural resources—such as sunlight,^[2] wind, rain, tides and geothermal heat. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation)^, followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption.
Some renewable energy technologies are criticised for being intermittent or unsightly, yet the market is growing for many forms of renewable energy. In response to the G8's call on the IEA.
Wind power is growing at the rate of 30 percent annually, with a worldwide installed capacity of over 100 GW, and is widely used in several European countries and the United States.

Liquid biofuel

Liquid biofuel is usually either a bioalcohol such as ethanol fuel or an oil such as biodiesel or straight vegetable oil. Biodiesel can be used in modern diesel vehicles with little or no modification to the engine. It can be made from waste and virgin vegetable and animal oils and fats (lipids). Virgin vegetable oils can be used in modified diesel engines. In fact the diesel engine was originally designed to run on vegetable oil rather than fossil fuel. A major benefit of biodiesel use is the reduction in net CO₂ emissions, since all the carbon emitted was recently captured during the growing phase of the biomass. The use of biodiesel also reduces emission of carbon monoxide and other pollutants by 20 to 40%.

A GOOD PLACE FOR A HOLIDAY,

I went to the Greek islands in August 2008 with my family and my brother's girlfriend. We went by plane.

We stayed in a pleasure cruise. We were there for one week. Isaw same hostorical things and beautiful beaches. The best place was Santorini becaue I loved the houses of town. At the end of the trip we went to Venecia and got on a gondola. I bought some clothes and a picture.

I recommend it because it's exciting. In the summer the weather is great!
