Kinetic Energy of wind

wave power is one of the most researched areas of renewable energy.

Wave power results from the transport of energy by ocean surface waves and its capture into systems that can be therefore used for useful applications

Some of these applications include electricity generation, the pumping of water, or water desalination.

Modern physicists have demonstrated that the energy in any electromagnetic field is made up of discrete packets. The term photon (meaning "visible-light particle") has been coined for these energy packets.

Cooperative effort within a group in order to achieve a desired goal

To give rise to imaginative or artistic abilities as well as the ability to find novel solutions to problems

Unlike fossil fuels, wave power doesn't cause air pollution.

When we look at what is available today in solar equipment it has come a long way  but still needs a long way to go.

Harnessing wave energy comes without the emission of harmful green house gases. This is the main motivation factor behind further development of this way of power generation.

Like with most green energy sources, wave power is also renewable. Since this energy source ultimately comes from the heat energy that is emitted from the sun, it will not disappear for some time – in fact, several billion years or as long time it takes for the sun to burn out.

The energy density is typically around 30-40 kW for every meter (2.2 feet) of wave along the shore. As we go further into the ocean 100kW for every meter is not uncommon.

Biofuels are basically any fuel that can be burned in air to produce heat that is produced by biological means, normally by plant growth. Currently the most prominant biofuels are ethanol and bio-deisel because these can be burned in existing internal combustion engines and are thus a direct replacement for oil. The most important biofuel historically is wood with oth

Biofuels are currently cheaper than oil although this is only because we are seeing very high oil prices at the moment. Under what might be termed more 'normal' market conditions, biofuels lack any meaningful price advantage. Biofuel production is very labor intensive and very land intensive. Production of ethanol from sugar cane was pioneered by the Brazilians in the 1970's as a solution to an oil import bill they could ill afford. It worked for them as they have plenty of land they can convert to growing sugar cane and at the time, plenty of cheap labor with which to harvest it.

he simple truth is the world does not have enough land to produce anywhere near the quantity of biofuels we need to make any dent in our oil consumption. They are only in fashion now oil prices are high and it is cost effective to produce them. Sooner or later food prices will rise to such a point that biofuel production will cease to be economic.

most all biofuels used today cause more greenhouse gas emissions than conventional fuels if the pollution caused by producing these "green" fuels is taken into account, two studies published Thursday have concluded.

The benefits of biofuels have come under increasing attack in recent months as scientists have evaluated the global environmental cost of their production. The new studies, published by the journal Science, are likely to add to the controversy.

When you take this into account, most of the biofuel that people are using or planning to use would probably increase greenhouse gasses substantially," sai
