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 Power, Worth The Hassle?
Filed under: Solar Green Energy Sources; Tagged as: bleach, chemical reaction, cleanliness, cloth diapers, coal, counterparts, disposable diaper, electricity source, energy from the sun, fad, fossil fuel, gases, home electricity, huggies, many things, power source, power supply, solar power, source of energy, worthwhile undertakingNo CommentsIn this piece of work that I am about to commence with I will discuss whether or not it is wise to convert or at least supplement your home electricity source with solar power. This is a worthwhile undertaking because there are many things in this world that are billed as cost or time saving and are actually the opposite when looked at with the right measurements or perspective.
So the question is, “is solar power what it claims to be—a clean source of energy that is cheaper than other forms, or is it merely a fad that makes people think that they are being kind to the environment or cost effective.”
So let’s talk about the claims. Number one: a clean source of energy. When you think about it the energy from the sun is about as clean and as natural as you get. There is no chemical reaction that creates an undesirable waste product, there is no burning, no smoke, no extra gases formed. So in this way—yes it is clean. But you also have to look at how you harness that energy. If you have to create undesirable waste such as plastic or other materials that can’t be naturally broken down; or you have to use energy that is not clean such as coal or other fossil fuel burning to create the product than you are at least decreasing the benefit of the clean power supply.

In the case of solar power you do have to create the cells which are made of plastic as well as the wiring and the housings for these cells. So there is some unseemliness to the cleanliness of this power source. The question is, does the benefit outweigh the costs? And in the case of solar power, it does seem that if the units are maintained and last for a long time they eventually will come out ahead. Not like cloth diapers which would, it seems, be a lot better for the environment than their disposable counterparts from huggies. The fact is that the bleach used to clean the cloth diapers is much worse for the environment than the disposable diaper which will eventually (though it takes many years) break down almost entirely.

Second solar power is a cheaper source of energy than other options. This again seems very true on the surface. After all everyone has access to the sun and the sun doesn’t charge does it? But then again the solar cells cost quite a pretty penny so it will take a while to pay them off with the cost savings. And you will have to maintain them paying a technician to come out and fix the units with expensive parts. So is it cost effective? Well again it seems as though over the long run yes solar power is a way to cheapen your energy costs considerably. Not like recycling which boasts of a way to save the environment and cheapen the cost of those materials that are being recycled. Well both may not be as true as stated prompting many communities to “recycle” the materials that they collect from well meaning residents right into the trash.
