A Bright Future For Solar Energy: An Alternative Energy Source

Aug 31

Posted by Alfred Lancer in Solar Power | No Comments

I was first introduced to solar energy in the movie, Race the Sun with James Belushi and Halley Berry in the lead. It was a story about low- income and under achieving Hawaiian students encouraged by their teacher to join the Solar Car race. In the movie, a car shaped like a cockroach and covered with solar panels used the sun’s rays as an alternative energy source to run the car.

Solar energy is the light and the heat from the sun. Solar energy is free and its supplies are unlimited. There are n air and water pollution caused about by using solar energy. But there is still some impacts on the environment although indirect.

Photovoltaic cells used to convert sunlight into electricity uses silicon and also produce some waste materials. There are also large solar thermal farms and these farms can also be harmful to the environment and desert ecosystems if not properly managed.

Solar energy can be used on different aspects. Solar energy can be used in agriculture. Greenhouses (which is entirely different from greenhouse gas) convert solar light to heat to be maximized in enhancing the growth of plants and crops. Greenhouses has been around since the Roman times and modern greenhouses were built in Europe in 16th century. Greenhouses are still an important part of horticulture nowadays,

Daylight systems are also being used to maximize the energy released by the sun. It is used to provide interior illumination replacing the artificial lighting. Daylight systems include sawtooth roofs, light shelf, skylights, and light tube. Daylight systems when they are properly implemented can reduce lighting-related energy consumption by 25 percent.

Solar energy can also be developed into solar thermal technologies which can be used for water heating, space heating, space cooling and process heat generation. Solar energy can also be used to distil water and make saline or brackish water potable or drinkable.

The solar water disinfection or SODIS involves exposing water-filled plastic polyethylene terephthalate or PET bottles. This process takes a long time, since the exposure time varies on the weather conditions. It requires a minimum of six hours to two days during days with overcast conditions. Currently, there are two million people in developing centuries use SODIS for their daily drinking water needs.

Also sunlight can be converted into electricity using photovoltaics or PV. PV has been mainly used to power small and medium-sized things like a calculator powered by a single solar cell. There are homes powered by photovoltaics. Using solar energy for water and space heating is the most widely use application of solar energy. While ventilation and solar air heating is also growing in popularity.

There are three main ways in using solar energy. The main way of using and converting solar energy is by using the solar cells. Solar cells convert light directly into electricity. Solar cells are also called photovoltaic or photoelectric cells.

Meanwhile, solar furnaces use a huge array of mirrors to concentrate on the Sun’s energy into a small space and produced very high temperatures. Solar furnaces are also called “solar cookers”. A solar cooker can be used in hot countries to cook food.

With all the benefits if using solar energy, there is still a downside for this alternative energy source. It does not work during night time. The cost of setting up solar stations is expensive, but the benefit of using solar energy when accumulated is so much more.

Searching For Information About Alternative Energy Sources

Aug 31

Posted by Trevor Gartreese in Energy | No Comments

With years came the destruction of many valuable resources. Today the world is faced with the biggest problem; lack of resources to carry out even the most mundane duties of a persons day to day life. This shortage of fuel, water and other important resources has raised issues in many countries. Today, the usage of alternative energy sources has become important than never before.

Countries that supply oil are aware of these shortages and therefore increase their prices each year. The more we lose the more problems we are faced with. Many governments are ready to go ahead with alternative energy sources, simply because of the high prices in the already lacking resources.

The first time the need for alternative energy sources came up in the United States in the 1970’s. An oil shortage in those years resulted in individuals staying at long queues in gas filling stations. It is not only vehicles that had this problem. Households suffered with a shortage of gas and other energy resources that were used in their day-to-day lives. This became a critical issue and experts started to find alternative energy sources to solve this issue.

Up to date, many experts have made several advancements in their search for alternative energy sources, but the fact remains that the prices of resources we use today are higher than never before.

When talking about alternative energy sources, the wind, water and sun are some of the main three resources that are put into this use. If the technology is used properly with these resources, a more cost effective mode could be made. Instead of oil being used, people could replace it with such alternative energy sources and use it to turn their turbines for the generation process. Geothermal power and hydropower are also some of the alternative energy sources that are used today.

Although there are several alternative energy sources that can be put into use, one must know that not everyone can use the sources the way they want. For example, a person who lives in a geographic area that has less wind cannot use wind as a means to turn their turbines to generate electricity.

People living in areas with little exposure to the sun may find it hard to use solar power to generate electricity. Therefore depending on the geographic location, the usage of alternative energy sources may differ.

Solar Panels Becoming Less Expensive

Aug 29

Posted by Joseph Dungler in Energy | No Comments

New research on the life expectancy of this new kind of renewable energy has helped decrease the cost of solar panels. It was once estimated that solar panels would last only about 20 years, but it has now been proven that models can last up to 30 years. This makes it a more appealing investment for homeowners who were hesitant because of the short life expectancy.

Green research institutes as well as various governments have been encouraging consumers to choose solar energy. In addition to encouraging consumers, they have also been encouraging financial institutions such as banks to make the finances available for this type of purchase.

Across Europe, and even China, governments have been giving financial incentives for those private citizens who upgrade to solar energy. This, of course, has decreased the cost of solar panels and increased demand. India and the United States have incentive plans in the works but have yet to release and implement them.

Before, I mentioned how this type of renewable energy will pay for itself and here is why: the major expense of solar panels is the purchase of the actual equipment and its installation. The rest is almost free because you do not have to pay for the energy source.

There are optimistic goals set out in the renewable energy industry. Some experts in the field are setting their expectations as high as having half of Europe dependent on solar energy in comparison to electricity grids as soon as 2020. Not only that, but with increased demand and usage it will make solar energy as cheap as buying it from an electricity grid.

Around the globe the demand for renewable energy is growing. More and more citizens of the world are becoming more conscience of the effects of our actions on the environment, increasing the demand for green energy. This demand will cut the cost of solar panels even further.

By learning how to build a solar panel, you can save money and even build a pool solar panel.

Aug 28

Posted by Dicky Rejaka in Solar Power | No Comments

This is a fact that the fossil flues that most power producing businesses world wide use are becoming scarcer with each passing day. It is fact that the emissions from the conventional fuels that are being used to produce electrical power have and continue to harm the environment. It is usually a fact that there are many of solar energy facts that remain unknown to many people.

Here are a few solar energy facts that I have learned recently that I want to mention along with some better known facts. Not every one of the solar energy facts are and only solar power. But in the short time since I started my research I have discovered many more pros than cons. First I want to list a few solar energy facts that may be viewed as drawbacks.

- Many people don’t understand that you have options to conventional fuels.

Any difficulty . it sometime takes a crisis for a lot of, like me, to begin a little shopping around into what you can do to make things better.

- Solar electricity can only be produced darning daylight hours.

Through the night hours, power has to come from storage batteries or the commercial power grid.

- New solar panels installed by contractors are expensive.

It’s a solar energy fact that the cost is coming down as technology matures. Also, the government and many states are giving tax rebates, credits and grants to help offset initial cost.

Now, let’s list some solar energy facts that could be considered pros.

- Solar electricity is requires only one form or raw material, sunlight. Sunlight is free to use worldwide.

- Sunlight is an inexhaustible resource and it produces renewable energy. The sun shall be around for years to come. No one that I know of has a really good handle on how long for sure, but many of us are betting on a long, long time.

- Solar power electricity works. It is clean and efficient.

- Solar power electricity can be implemented in steps. Many households worldwide start with only some needs connected to solar power. The solar power system can be contributed to as your budget and desires allow.

- Solar panels require very little maintenance. The solar power generator system has no moving parts to wear out and replace. Cleaning maybe once or twice a year is usually all that’s needed is.

The solar energy facts listed above are for no reason the many positives and negatives, there are both that may be found with a small bit of effort. It is a great idea if you’re concerned about their power bills and/or the fitness of the environment, to study on solar energy facts.

Directing Some Lights Towards The Solar Panel Technology Choice

Aug 23

Posted by Thomas Sullivan in Solar Power | No Comments

Certainly, solar power will be the wave of the forthcoming future. Solar power manufacturing is an exceptionally basic method to be able to fully understand. A solar, also known as photo voltaic, cell collects energy right from the suns rays. A photo voltaic cell is actually a semiconductor unit that is created utilizing photo voltaic components. It includes absolutely no fluids or chemical compounds, with no moving portions. Pv cells change sun energy directly into electrical power.

The solar panel commonly includes a group of individual cells, that are sustained by a system that allows the individual cells to operate together. The energy that is captured with the solar panel is usually stored in a battery. Solar panel products create direct current (DC) electricity. Numerous solar panel technology systems come with inverters within them which in turn will allow for direct current (DC) electrical energy to be transformed into alternating electric current (AC). Nearly all consumer products including appliances as well as electronic devices run on Alternating current.

Unless you have a huge field of acreage to be able to accommodate a large selection of solar panels, it’s improbable that you’ll be in a position to power your entire house using solar panel technology. However, you can actually power one particular room within your house by using a modest selection of panels mounted to the roof top of your own home. Multiply the actual wattage of every particular electronic gadget by the amount of hours you imagine to make use of them on a daily basis. That combined range shall be your benchmark, or maybe the smallest amount your system must be able to generate.

You have a variety of possibilities to people who are thinking about converting to solar power. The common system which you can use to power your personal computer and a few additional small items can be acquired for about $1000.00. Obviously, the price increases depending on the generating capacity of your system. In most areas, the price tag on a set up model will set you back somewhere in the price range of $10.00-$12.00 for every watt.

Solar Energy is one of a few genuinely environmentally friendly solutions which can be employed when it comes to electric as well as power generating. Every hour of each and every day, sunlight blankets our world with more than enough strength to support our global electricity requirements for a calendar year. When the technology driving solar power increases, individuals are going to be unable to refrain from the urge to transfer.

Plenty of resources are now being dedicated to the actual continuing development of solar energy technology. A lot of the main oil and energy organizations currently have entire sections dedicated to solar technology. Research workers and technicians are spending countless hours attempting to cultivate the technological innovation right now that may greatly improve conditions on the planet tomorrow. It is no hidden secret that individuals cannot continue on down the path we are on. Classic fuels shall no longer be any kind of viable choice with regard to power production.

Solar Power At The Industrial Level

Aug 22

Posted by James Hull in Solar Power | No Comments

Several new solar power plants are under consideration in such locations as California and New Mexico who have regular patterns of Sun. It is fair game to inquire, then, on the overall effectiveness and practicality of solar power systems on the large scale. How much can solar power be used to provide for America’s energy base?

The proposed answer is simple. Pound for pound and dollar for dollar solar power stations can not create the output of a fossil fuel power station. The energy trapped in coal, natural gas, and diesel fuel is very concentrated and very potent. Combustion fuels will continue to outperform the renewables market for as long as carbon based fuel prices remain low.

Combustible fuels are simply solar energy stored up millenia before so you don’t have to think of them as unnatural or bad. Without fossil fuels we would have no way to support our industrial base and would be without out many of our modern technologies.

Most of our comforts and commercial activities are founded on several industries. This foundation includes the mining of ores from the Earth, and the manufacturing of raw materials such as aluminum, iron, steel, copper, and more. It includes plants to produce airplanes, automobiles, machinery, tools, electronics and every little gadget we use on a regular basis. It also includes large machinery required for harvesting lumber and other agricultural products.

Simply put we use a lot of electricity in our regular daily lives. This energy is embedded in the infrastructure around us, our industries, and is most easily supported by combustive energy.

And here is the fundamental problem with large solar power plants. They can’t supply adequate energy to support America’s industrial base. This does not mean they are irrelevant or undesireable. It just means solar power systems make the most sense when used in residential and small commercial applications where energy consumption is moderate.

As an example, a 500 MegaWatt combustion power plant can fit in a relatively small space, less than a 1/4 square mile without much difficulty. When considering a photovoltaic solar power plant, nearly 1,140 acres (almost 2 square miles) of solar panels would have to be installed to equal this same capacity. This is 2 square miles of actual solar panels, and does not account for the mounting and maintenance space. Being that solar panels provide peak power only 5 to 7 hours per day, then apples to apples we’re only getting the total output with more than eight times the space!

Where the weather and sunshine justify the use of solar power we need to integrate this useful power source into our energy portfolio. We must pay homage, however, to our modern combustion technologies. Modern combustion systems are cleaner and more efficient than ever before, and provide enormous amounts of power 24 hours a day. The energy density of fossil fuels is just to high to ignore when it comes to powering America’s industrial base.

What Is A Carbon Foot Print?

Aug 21

Posted by Claire Pickett in Energy | No Comments

We’ve all heard the global warming story. News reports, magazine articles, and television shows of every kind have told us that it is vital for people to reduce, recycle, reuse. We’ve had greenhouse emissions and carbon footprints beaten into our brains. So what does it all mean?

What are Greenhouse Gases?

Before understanding this, we must know about the earth’s atmosphere. The air that we’re breathing isn’t the only thing. In space, the earth is surrounded by gases. The gas protects us from the sun. It regulates temperature as well.

The protective layer has oxygen, nitrogen, methane, ozone, water, and carbon dioxide. All of these are greenhouse gases. Greenhouse gases have been artificially increased by humans.

What is a Carbon Footprint?

We have built our lives around machines that require power. Cars and transportation are included in this. In order to power the machines we must burn fuel. When we burn fuel, we increase the energy that radiates from the earth and settles in the layer of greenhouse gases in our atmosphere. Levels of gases are changed in the atmosphere because of this.

More extreme weather between seasons happen because of this. We may experience colder winters and hotter summers with the increase in intense storms throughout the year. Summer of 2010 has been the hottest around.

In the past century, the levels of carbon dioxide have increased. Fossil Fuels are any fuels that we have to dig or drill into the Earth to find. The carbon footprint is generally the measurement of increased levels of carbon in the atmosphere.

What Can I Do

Scientists have warned that we must reduce our carbon footprint. Conserving energy is one way we can manage this. By minimizing the distance you drive each day or carpooling to remove one or more cars from the road, you are doing your part to reduce the carbon footprint. You can also use fluorescent lights in your home. They are shaped like a custard cone serve at the county fair, but are serious business. They will save money and energy in the long run.
