Our planet receives enough raw energy in the form of sunlight in sixty minutes to illuminate all of the worlds lights for a full year. Unfortunately, a very small part of it can be harnessed so most of the population still gets most of its energy from power plants that burn fossil fuels. Fortunately for our environment, we have recently seen an increasing trend in the demand for solar energy. This is partly due to the fact that solar panels are becoming cheaper as technology advances.

At the equator, the Sun provides approximately 1000 watts of energy per square meter on the earths surface. That means that 1 square meter of each panel can generate approximately 100 GW of raw power per year. That amount of power is enough to illuminate more than 50,000 houses. The entire area that would need to be covered by solar panels to power the entire world for a year would be the equivalent to one percent of the entire space of the Sahara Desert. The amount of power solar panels can generate on a given day depends on a few variables like smog, cloudy days, low temperatures and humidity.

Solar panel farms are a lot like other normal power plants with the only big difference being that most power plants get their energy from fossil fuels. And when conventional plants burn fossil fuels, they generate the by products which are contributing to global warming. Solar panel farms or solar heat plants (or CSP plants) absorb the rays of the sun to generate electrical energy.

This process of energy conversion in solar heat plants rather simple. The panels absorb the rays of the sun, which then shines on the power receiver. In this receiver, the energy is converted into steam from the suns rays. The steam is taken to tanks where it will be used to spin turbines and generate electricity. The process is clean because it requires no fossil fuels to be burned. It is safe for the environment and doesn't contribute to global warming like conventional power plants.

If more solar panel farms are implemented, the demand for oil will be reduced sharply. Today, there are many households that use solar panels for energy and more people are adding panels every day. When this demand for solar energy and other alternatives goes up, fewer people will use gas and fossil fuels, and the prices for these will surely drop as well.

If you use solar energy, you may actually be able to use "negative energy". Because every house is connected to the city's power system, the extra energy that your panels produce will go back into the grid and can be consumed by other households. This will result in you being sent a check by the electric company for the energy you put back in. Even if you panels are small, you will see a huge reduction in your bill. These solar panels, aside from being good for the environment, are good for your pocket!

Even though the initial investment into your solar panel system is a bit expensive, the panels will undoubtedly pay for themselves in the long run. Not only do you save money and perhaps even make some with your panels, you help the environment by reducing greenhouse gases and emissions. These systems are so durable they have been known to last years. PV cells are supposed to stay good anywhere from twenty-five to forty years. Most suppliers of solar panels have a standard twenty-five year warranty.

Finally, solar panels take minimal maintenance and they can be placed basically anywhere that gets a good amount of sunlight all year.
