A Detailed Analysis of Wind Turbines as an Energy Source

Author: John Newcomb

Most countries in the world today understand that we are standing at a ‘now or never’ precipice. The more we delay our quest for a clean, renewable source of energy, the more dependant we will grow on environmentally unfriendly fossil fuels, and let our energy usage and demands get out of control. Of the various sources of alternative power, the most promising are nuclear power, solar power, and wind power. Wind energy, although it has been used since time immemorial, has made great strides in the past few decades and is now a viable alternative to oil or coal power. Wind Turbines Wind mills have been used for centuries to grind grain. A wind turbine works on a similar principal. The wind turns the blades of a wind mill which, with the help of gears and magnets, produces electricity along the power lines attached to it. The power generated by a single wind turbine is small, but harnessed over thousands of such turbines, can rival that of a decent sized coal or oil power plant. Wind Turbines and Location One of the most important aspects of a wind turbine is its location. Since they need wind to function, they can only be set-up in windy regions. Our current technology cannot store the electricity produced by wind turbines into batteries, which makes it paramount that such turbines be installed in regions where there is always a strong wind blowing. Moreover, most wind energy plants require hundreds and thousands of wind turbines to generate a decent amount of electricity. Thus, wind turbines, at present, can only be used locally in large areas that receive heavy wind for a significant portion of the year. This obviously limits their effectiveness quite a bit. Bad Neighbors In certain pockets of West Texas where wind energy farms have been set up on a large scale, locals have been complaining about the eye sore of wind farms, and the constant sound they make. This has caused some fairly complex legislative problems. As wind farms creep more and more towards urban areas, this issue can only cause more problems in the future. No Way Out Although the issues people have regarding wind turbines are legitimate, one needs to understand the complex nature of the problem. If we do not adapt to better, c

Wind Turbines

Wind mills have been used for centuries to grind grain. A wind turbine works on a similar principal. The wind turns the blades of a wind mill which, with the help of gears and magnets, produces electricity along the power lines attached to it. The power generated by a single wind turbine is small, but harnessed over thousands of such turbines, can rival that of a decent sized coal or oil power plant.

One of the most important aspects of a wind turbine is its location. Since they need wind to function, they can only be set-up in windy regions. Our current technology cannot store the electricity produced by wind turbines into batteries, which makes it paramount that such turbines be installed in regions where there is always a strong wind blowing.

Moreover, most wind energy plants require hundreds and thousands of wind turbines to generate a decent amount of electricity.

Lease Your Solar Panels For a Fraction of the Cost

Author: Tina Metcalf

This may be the best way to go solar for everyone. Lease your solar panels, no money down, and they will be installed for free!

Instead of any large up front cost, leasing your solar panels might be the best solution for a lot of people. Generally there is no purchase price on either the panels themselves, or the installation to get them on your roof. All you would do is pay a set fee every month to have them there, just like you would do if you were leasing something, like say, a truck or an an automobile.

The company that installs your panels will charge you a set price for 10 or 15 years worth of service, and during that time, they will handle all maintenance and repairs if needed. You will still pay your electric bill, but with the solar panels generating electricity on your roof, your bill will be much lower. And if the panels produce more power than you use, it gets fed back into the grid, and the electric company pays you!

Most people realize a savings of 10 to 20% over the life of their solar panels, and when the lease is up, you have the option to pay off the value of the panels. After that point, with the panels still generating power, you may not have an electric bill anymore.

These leasing arrangements are cropping up all over the US, and your local solar provider or even your hometown electric company should be called to find out if this program is available in your area.

This might be a terrific way to defer the cost of pollution free solar energy and get it done now.

What Is Photovoltaic Solar Power?

Author: JR Chuong

Photovoltaic solar power, (PV) is the most common form of solar energy in the world.  PV solar panels are made out of semiconductor devices derived from very pure silicon that when exposed to the solar power from the sun they generate electricity.  Semiconductor materials has unusual properties, they do not conduct energy like metals and are not insulators like most minerals or plastics.  They have an atypical electrical property enables them to convert energy from the sun to electricity.   The actually PV solar panel is has a surface charged with extra electrons, and a second surface that has positively charged atoms missing electrons. When solar energy rays from the sun hit a PV cell a portion of the solar power is absorbed and the extra electrons become energized and bounce off positively charged surfaces making an electrical current in which the two surfaces collide.  This electrical current is solar energy that is used to solar power your home

Solar panel PV cells can be arranged together to create solar power sources of varying sizes. Small arrangements, known as modules, can be used to power electronics or appliances like a battery would. Large groups of PV cells can be used to build solar energy arrays capable of creating enormous amounts of PV solar energy. Depending on the size of the array and the amount of sunlight, solar energy systems can create enough power to run homes, factories, or cities.  PV solar power produces no pollution does not create carbon dioxide or produce any greenhouse gases.

Many solar energy scientists believe that solar power is of vital importance to society’s survival. Today, the world is largely dependent on energy that comes from fossil fuels like oil and coal. These fuels are a product of the decomposition of organisms that lived millions of years ago and are available in limited quantities.  PV solar power along with wind, hydroelectricity, biofuel, algae and geothermal power are some of the most promising forms of energy our planet has.
