The central renewable energy advantages are the very fact that they are renewable. We won’t ever run out of supplies of renewable energy.

Solar energy – the sun will permanently be there, and in abundance – the amount of solar electricity intercepted by the Earth each minute is bigger than the amount of power the world uses in fossil fuels every year.

Wind energy – the wind will always be present – The power in the winds that blow across the U. S. Yearly could generate more than 16 billion GJ of electricity – more than one and one-half times the electricity consumed in the United States In 2000.

Tidal energy – the moon which supplies the forces that causes the tides will always be present

Hydroelectric energy – unless there is a drastic variation in rain patterns, it will always be there

On the other hand, non-renewable resources like traditional fules are limited – our resources of them will run out in the end.

A second renewable energy advantage, is that renewable energy is environmentally friendly. The reason being since they don’t give off CO2, the largest contributor to global temperature rises, into the atmosphere.

Non-renewable resources like petrol discharge CO2 into the atmosphere when they are used for creating power. Additional renewables such as biofuels are carbon neutral – producing them uses about as much CO2 as using them produces.

Renewable energy resources can be re-used and are straightforward to discover. But the non-renewable sources can not be used again.

Today any one, can construct their own renewable electricity generators at home and enjoy the advantages of renewable energy. A number of plans and guides now exist to show you how to construct a wind mill out of pvc pipes or a solar cell out of basic reflective glass and all for very little cost. Consider these renewable energy advantages for making the easy and reasonable switch to natural electricity.

One small wind mill can make the equivalent amount of natural electricity that synthetic and fossil sources do while putting out 5000 tons of CO2 simultaneously. Scientists virtually collectively agree that once the larger population of the earth welcomes renewable energy, we’ll begin to see a fast reversal of the greenhouse effect.

It is the Future and Builds For a Better Future. Natural and renewable energy advantages outnumber the application of traditional fules, and eventually we will have no choice but to use these natural supplies. Limited sources of fuel are quickly lessening as the energy crisis continues to bear down on us.

It’s Cost Effective and is simply the largest and most well-liked of the clean energy advantages is that it’s extremely cost effective. In the beginning, the average homeowner spends about $2500 each year on their electricity bills alone. Think of not relying on the power company for that electricity and instead selling back any exess renewable energy which you manufacture but don’t use in a given month to the power company for a profit.

To end with, do not overlook the substantial and generous tax breaks that the government, particularly now under the Obama government, hands out each year to those who embrace clean, natural energy.embrace clean, natural energy.

Lots of individuals do not realise that it is possible to use renewable energy such as solar power and wind power to produce sufficient electricity so that you could save as much as 80% of your normal electricity costs, in fact in a number of cases it is even viable to produce so much electricity that your are able to sell it back to the power company.

Tidal energy is a form of ocean energy that is in use today. It is a renewable energy option that has its benefits and its applications. Some of these applications as well as these benefits are considered here.

A lot of energy is available in waves of the oceans and by harnessing this power you can use another of the Earth’s most renewable energy sources.

Anyone who has ever been to the ocean will testify to the power of the waves that crahs along the shoreline as the tides come in. The tides of the ocean are as a result of the gravitational pull of the sun and moon and they are also a result of the Earth’s rotation too. These forces cause ocean waters to rise and be lowered from time to time. Tides have different cycles of twelve and one half hours everyday; they also occur twice a day and can be easily predicted.

The use of tidal power was visible as early as the 12th century when tidal mills would use the force of the tides in order to grind grain and corn. The 18th century resulted in competition from windmills as well as waterwheels. Tidal mills became somewhat extinct with the invention of cheap steam engines. In 1967 France was the first to use tidal wave power on a large scale in order to produce electricity.

Generation of electricity from tidal waves is somewhat similar to hydroelectric power generation. Bigger dams which are known as barrages are built at the bottom of a tidal basins. Gates on the barrage permit the tidal basin to fill during the incoming high tides. Likewise this basin will tend to empty through a turbine during a period of ongoing tide. In turn this creates an electric generation that helps in the production of electricity. Systems also exist which generate electricity from incoming and outgoing tides as well. Negative effects may result with the plants and animals present in the area.

Tidal fences may be used to generate electricity as well. Vertical axis turbines are mounted on these fences and passing water is passed through these turbines. Ideal locations for these tend to be channels placed between the two landmasses. Tidal fences tend to be cheaper than tidal barrages but they cause a lesser environmental impact on marine life.

Tidal turbines are a relatively new technology that is used for tidal energy. These turbines operate somewhat similarly to wind turbines and they are arranged in rows underwater. They work better in areas that have strong tides. They may be heavier and costlier to build but they tend to capture much more energy. They damage less of the environment that other methods as they do not affect migration paths of sea life.

Tidal power requires a tide difference of at least 16 feet in order to function. However there are very few places where this can occur. You can’t just construct tidal power plants anywhere. A handful of places exist which are capable of the production of this power range. France happens to be the only successful country that has harnessed this tidal power effectively. Currently people hope that certain technological developments will through research develop better ways to harness tidal power as a replacement for fossil fuels.
