Our Energy Future Comes From The Sun

Now a days everyone is talking about the environment. From global warming to conservation, many are looking for ways to save the Earth essentially. Some have found a huge equalizer with solar electrical panels.

Furnished from silicon, these incredible tools literally take in radiation from the sun and turn out usable electricity. Seems simple enough right? Well, here's a short version of what actually happens.

Photons found in the sunlight collide with the surface of the panel itself in such a violent manner that it creates a lot of energy. This energy is enough to set nearby electrons out of their orbit in their electron fields and float off freely. The solar cells infused in the panel then direct the free floating electrons into one path, or current, and send it into your home and to its desired end.

Why solar energy? When posed with the current state of our ozone, many folks are thinking "green" and coming up with truly inventive ways to change how things have been done for a very long time. Coal energy is still one of the most used resources to provide electricity, and to some, it stands to be the most destructive as well. There is no argument that the current methods (with the exception of wind and solar power) for attaining consistent electricity have very damaging effects on the environment.

You might ask: "Is solar energy something I should be considering?" And for some the answer may be yes. It really lies in your level of commitment to this renewable resource and the pros of owning your own system. It also beats trying to harness wind energy by setting up a giant windmill in your front yard.

But that is not to say that running solar panels to replace your dependence on coal and nuclear energy will be cheaper, at least not at the moment anyway. The alternatives in nuclear or coal-produced electricity will be a loss less detrimental to your wallet until more people get behind solar energy.

It is pretty easy to come to the conclusion that those who have set up these systems have either an incredible passion for the environment.

Solar electrical panels are conduits for individuals to help the environment and release their dependence on environment damaging norms for their electricity needs. While it may require a little more start up to install and maintain, the overall pros of solar energy greatly outweigh the cons. So what's stopping you?

Has the time really come where the world could be potentially self sustainable in terms of its energy supply and demand? Well sadly the answer to that is, not yet. However one step closer to achieving this is roof wind turbine power. Roof wind turbine models have been on the market for a number of years now but they are really coming into age as they are becoming more efficient, cheaper and easier to install.

Previous roof wind turbine models were overly bulky, not highly efficient and quite limited in their operating conditions. The period of time to pay back these models in regards to the money you would save using them was extremely long due to their cost to buy and install. Taking into consideration their maintenance costs this pushed the return period even further back. The newer roof wind turbine models can usually be installed by a good electrician and a far less costly.

Wind turbines are a booming industry. Who really wouldn't want to be independent from the Grid. It makes sense in so many ways. The roof wind turbine market only makes up a small share of this market but it is growing in leaps and bounds as people wish to take the renewable option to save money and help the planet.

In terms of the pay back period of the latest roof wind turbine devices you are looking at about 5 years compared to up to 20 years for ones you would have bought 4 years ago.

If you buy a small scale wind turbine system before December 2016 you will receive a 30 percent rebate from the government. This applies to wind turbine units with capacity under 100 kilowatts.

The latest models of wind turbines have eliminated the need for a tower to be erected to hold the devices as they now attached directly to your rooftop. This has gotten rid of two main problems. One being the need to get approval to erect a tower and the other reducing the costs dramatically as an expensive tower is not required.

The greatest advance in wind turbine technology has been the replacement of a gear and gearbox system. These systems required a wind of 7-8mph just to start the gears turning, obviously reducing efficiency. Almost a 25% reduction resulting from the initial power required as well as the loss of energy in the gear box. To replace the gear system modern engineers have used hubs and bearings and instead of a gear box magnets are used to generate electricity. New systems also boast greater wind acceptance scope as well as turbine blades which can easily be taken off and replaced in the event of damage.
