Benefits of electric cars
Ever since the invention of the first car, people have been experimenting on the different ways on how to power the car and the electricity powered car was one of those experiments. Back then, the batteries were rather primitive or crude and it really didn’t last long. Also, recharging the batteries was expensive and it took a very long time. These are the reasons why electric cars back then didn’t really catch up with people and the car powered by the internal combustion engine was more convenient, efficient and a lot cheaper. Today however, electric cars are far more advanced than what was available in the past.
Thanks to the advancement of battery cell technology, electric cars today are now able to go faster, further, and last longer. And, the batteries can be charged at a very short period of time. In addition to that, electric cars today are a lot cheaper to power than gasoline powered car. You have to consider the fact that the country or the whole world is going through a financial crisis. With gasoline prices constantly fluctuating and because people want to save as much money as they can, a lot of people are now getting rid of their gasoline powered car and they are exchanging it for electric cars to save money and the environment.
In order to lessen the dependence of the country on foreign petroleum products, the federal government is encouraging people to buy electric cars by offering huge tax breaks on people who owns and uses electric cars. In some states, they also offer benefits to people who drive electric cars, such as exemptions from carpool lane requirements and free parking on parking meters and pay parking lots.
Electricy with Solar
Solar electricity is created by using solar power cells to convert the sun light into energy. Solar electricity is created in solar panels that are constructed to take advantage of the photons in the atmosphere. The solar panels are constructed from specially treated materials that are semiconductors. These are mostly composed of silicon atoms. The panels are constructed of two sheets of this material and separated by an electric field to allow the atoms to interact from either side. This is done by using the energy of speeding photons to create an electrical current in a solar panel.
What are photons? Photons are created by the fusion of atoms in the center of the sun. It takes millions of years for a photon to make its way to the surface of the sun, but once they are free they are hurled fast enough to make it to the earth in about eight minutes! Another word for photons is quanta; these are actually little packets of sunlight. Solar electricity is simply changing the sunlight into electricity, sounds pretty easy doesn’t it? That’s what I thought when I first started researching it. The way it works is complicated for a novice like me but using it is as simple as the electricity in any home.
The only difference is that solar energy does not harm the earth. Solar electricity is built up in the solar panel and then it is transferred through a wire to a converter and then into your home. The energy from the sun is DC current so it must be changed into AC current for use in the home. The power from the newer systems can often produce more power than from your utility company. If you stay connected to them the excess power is fed into their lines and you receive a credit on your bill for this. It’s a great way to help the environment and save money at the same time.
