TheGreenBuzz :: The Facts About Solar Energy and Solar Power Plants!
Filed under: Solar Green Energy Sources; Tagged as: atmospheric humidity, concentrated solar energy, concentrating solar power, continuous development, conventional power plants, energy from the sun, energy requirement, gigawatt, greenhouse gases, power density, power of the sun, s rays, sahara desert, smart home owners going green, solar energy systems, solar power plant, solar power plants, solar thermal power, square meter, thermal power plants, use of solar energy2 CommentsThe earth receives more than enough energy from the sun in an hour to supply the world’s energy requirement for the whole year.
Unfortunately, only a tiny portion of it is harnessed and the world still relies on power plants that burn fossil fuels. The good thing, though, is that there is a constant increase in demand for solar energy; and over the years of continuous development, solar panels are much cheaper today.
During peak hours, the maximum power density that the sun can give is about 1kW per square meter. In other words, one square meter of solar panel can produce as much as 100 GWh (gigawatt hours) of electricity in one year. That is enough to power 50,000 houses.
If a solar power plant is build on 1% of the total land area of the Sahara desert, it will satisfy the world’s energy requirement.
The efficiency of solar panels depends on several factors such as pollution, clouds, temperature and atmospheric humidity.
Solar power plants are very similar to other conventional power plants – with one significant difference: The majority of power plants draw their power from fossil fuels like oil, coal and gas.
When power plants burn fossil fuels, they produce greenhouse gases that contribute to global warming. Solar power plants or solar thermal power plants (or Concentrating Solar Power plants) utilize the power of the sun’s rays to generate electricity.
The process could not be any simpler. The solar panels receive heat from the sun, which will be reflected to the receiver. The receiver converts into steam the concentrated solar energy. The steam is stored on tanks which will be used to turn the turbines and generate electricity.
The whole process does not involve any burning of any fossil fuels. Thus, solar power plants do not contribute to global warming.
The increase in the use of solar energy will bring down the demand for oil.
Why Smart Home Owners Going Green?
Today, there are more than 10,000 households with solar energy systems and the number is constantly increasing. If the demand for solar energy as well as other forms of alternative energy, the demand for oil will drop and the cost fuel will likely to follow.
Residential solar energy system can turn your electric meter backwards. Given that you are connected on a power-grid, the excess energy that your solar energy system produces will go to the electric lines to be used by other homes. As a result, any excess energy you give will be reflected on your bills. Your electric supplier will even pay for the electricity you supplied.
Residential Solar Energy System Can Save You Money
While the initial cash out for installing solar energy system at home is big, the device will pay for itself in the long run. Not only you will save money on solar energy system, you also help the environment by not contributing to carbon emissions.
Solar energy systems are reliable and can last for a very long time.
PV cells are last from 25 to 40 years. Many manufacturers of solar panels give 25 years product warranty. This is the assurance that solar panels are very dependable.
In addition, solar panels require little or no maintenance and the can be installed on most places where there is sunlight throughout the year. Looking for the #1 solar and wind power wesite? Smart home owners are going green and saving more green money for the future. Act today!

TheGreenBuzz :: Solar Powered Cars
Filed under: Solar Green Energy Sources; Tagged as: 19th century, Automotive, batteries, bet, Cars, electrical energy, elements of nature, existence, filling station, fulfillment, future prospect, heating systems, hidden treasures, life on earth, petrol, poll id, slow pace, Solar car, solar energy, solar power, solar powered car, solar powered cars, source of life, thermal power plantsNo CommentsThe elements of nature have been created for man alone. Every single need can be acquired and it is present in nature around us.
Man only needs to travel and explore the hidden treasures of nature and use them for the fulfillment of his basic needs of life. Something that doesn’t need any searching shines up above in the sky. The sun is the basic source of life on earth. If there was no sun no life would have been possible.
Sun emits light which is known as the solar energy and you may have heard and studied about solar energy being used for thousands of purposes. This energy has been used for heating systems and thermal power plants are run through solar energy and so on. When you read or hear about these things you simply pass on because this is too common.

When it comes to solar powered cars it is very likely that you stop and think for a while. It is a promising future prospect and you wish you live long enough to see only solar powered cars racing down the streets, no running out gas, no waiting at the filling station, no more paying for the petrol. Imagine how quickly you would be able to increase your standard of living.
Solar powered cars have been in existence since the mid of the 19th century. They have been increasing in number year by year and organizations tend to hold solar powered car racing each year and thousands of people invest their money and bet on their solar powered cars. The mechanism of these cars is very simple. The batteries installed in these light bodied cars charge themselves from the solar energy. Then this energy is converted by them into electrical energy thus it helps the motor run.

Now this prospect is very simple or more likely it sounds very simple and trouble free. The sun shines everyday and there doesn’t seem to be any such problem with these cars. But the fact is that the amount of energy stored at a time by these cars enables them to drive at a very slow pace. The road has to be leveled and not steep because that requires even more energy. It will need more powerful batteries and more storage capacity.
Have you never noticed that this is the reason why solar powered cars are small; light weighed, and can carry one person at a time? There are many technical facts that render the concept of these cars as vague.
