Solar Energy

Over the last few years, businesses have experienced drastic climbs in their energy costs, a trend that will only continue. If utility costs make up a good deal of your overhead, skyrocketing energy rates can have a devastating effect on your business. Solar energy is completely free, a gift from the sun every sunny day. Use this gift to save money and make profit. Here's a look at how businesses can take advantages of solar energy.

Cut Utility Costs
As utility rates continue to escalate, your company will not be as affected as much when you are already harvesting your own solar power. Every sunny day, you can watch the electric meter tick backwards, so you owe the electric company less every month. You won't be as affected by steep rate increases when a good portion of your energy is getting a suntan on the roof.

Emissions Trading
President Barack Obama has indicated that the US will enter a cap and trade program to control global warming. In the near future, greater governmental pressure will make for very valuable pollution cuts. You can use solar energy as a renewable resource to slash your company's emissions rates, selling resulting credits to more polluting companies. Make money from the sun with emissions trading and the advantages of solar energy.

Tax Credits and Rebates
Obama has also made it clear that he wants to invest in America's renewable energy resources. Many tax credits and rebates, both federal and local, now exist that make solar energy more affordable than ever. This is money on the table that's there for the taking. Solar energy always ends up paying for itself, but it pays the bill even quicker with the tax credits and rebates currently available.

Free Resource
Sunshine is always free. Invest in the infrastructure, and then the sunshine pays you back. Solar panels are almost completely maintenance free, so there are very little costs involved once you've got them up and running. They continue to pay for themselves several times over. Once you've invested in the structure, solar power becomes as free for your business as it is for the flowers.

Solar Power System

Solar power relating to houses becomes more popular each year. Because the cost of manufacturing decreases it is quickly turning into an affordable and practical option for a lot of home-owners. The government is assisting individuals with tax concessions they offer to people that elect to go green.

Why Use Solar Power?

Solar power for homes is good for the environment as it does not contribute to green house gas emissions. Just the use of solar power to heat our water drastically reduces carbon dioxide from being released into the atmosphere.

How does the Government help?

Solar Credits is the term assigned for the Australian government's latest solar subsidy for homeowners, businesses and neighbourhood communities. On 20 August, the program was authorised in government law, subsidising the expense of supply and install of a new solar renewable energy system (no means testing necessary). This program is in contrast to it's predecessor which was means tested for a home income of $100,000. It's the most recent in a variety of schemes, which unfortunately appear to change more often than most of us can keep up with.

The questions people most commonly seek the answer to are:
  1. How much will I be able to receive off the price of a solar system?
  2. How much will a solar system cost us currently?
Typically, if you would like a new 1kW system, you will get approximately $3,500 off the cost. If you'd like 1.5kW or more you'll then be able to reduce the cost by around $5,600.

So how much does this mean you could spend on a system?
Here are some ballpark figures with regard to costs. They'll differ by a thousand or so either way depending on the brand of panels and inverters suppliers use, as well as their particular overheads.
  • Typical price of a 1kW solar system is approximately $8,500
  • Government's Solar Credits Rebate is $3,500
  • Cost to you personally to get 1KW of solar power is is around $5,000
  • General cost of a 1.5kW solar system is $11,500
  • Government Rebate is $5,500
  • Cost for you to get 1.5KW of solar power is around $6,000
As you can see, the way in which the Solar Credits scheme works, the 1.5kW system is actually much better value. You get 50% more electricity for only about a 20% greater cost.

The solar credits scheme maxes out at 1.5kW. If you want a system bigger than that your solar credits will reach it's limit at about $5,600. The good news though is that you will be able claim around $560 per additional kW in Certificates Renewable Energy Certificates (RECS).

  15. You can wire solar cells to increase the Voltage of the system (series wiring), to increase the Current of the system (parallel wiring), or to increase both, Voltage and Current (series/parallel wiring).
  16. Solar powered systems with a battery can provide a homeowner with electricity even during the time of local power outages.
  17. You do not have to connect a home in the woods to a power grid, if you provide it with a powerful enough solar power generator.
  18. Solar energy is very safe for the environment, since it produces negligibly small amounts of elements, and only during the process of manufacturing the solar materials.
  19. In the future, we may see cars and houses painted with a translucent solar paint to generate energy.
  20. Solar energy won't run out until the sun ceases to shine, which is estimated to happen in about 5 billion years from now.
As you can see, there are numerous good solar energy facts. It's also a fact that the whole world is anticipating further drops in the price of solar material, so that everyone will be able to enjoy all of the solar power benefits at a reasonable cost.

Wind Energy Or Solar Energy

When choosing the best option for reducing your power bill, it is important to understand the benefits and drawbacks of two of the most popular energy sources: Wind Energy and Solar Energy.

Solar Energy

The earth does not produce energy on its own. Solar Energy creates two other sources of energy often utilized by homes and businesses: water and wind. Solar Energy is collected using various types of Solar Panels, which is then channeled into a home via "Grid-Tie" or "Off Grid" systems.

The Grid-tie systems collect solar energy and feed it directly into your electrical system through a grid-tie inverter. In this arrangement, the electric company is essentially the storer of any excess electricity collected throughout any given day. The advantage of this method is the cost savings in needing to purchase a battery bank to store the energy. If you happen to produce more electricity than you use, many electric companies will pay their customers for each extra Kilowatt Hour (KWH) of electricity fed back into their system. However, the amount electric companies pay their customers for the electricity is not typically as high as the amount they would charge you for the same amount.

Off-Grid systems are the same as Grid-tie, except they store the extra solar energy collected by solar panels into batteries. The off-grid inverters cost less, but there will be a substantial battery cost. The amount of batteries needed will depend on the number of solar panels you have. The more solar panels you purchase, the more batteries will be needed to store the energy.

Some areas of the country are more suitable for solar energy than others. Solar Panels need the direct rays of the sun in order to operate at peak efficiency. Cloudy areas such as Seattle, Washington are not going to produce as much solar energy as places like Phoenix, Arizona. While Seattle is one of the worst areas, if you were to make a line that went from Minnesota to Ohio to Maine, that area of the country fares only little better in its worst month. See a Solar Radiation map for more specific information in your area.

Wind Energy

Wind energy has the distinct advantage of being available both night and day. When the storm clouds roll in, blocking the afternoon sun, wind energy is there to pick up the slack. Interestingly, wind energy is actually produced by solar energy, albeit indirectly. As the sun's rays come in contact with the earth, some areas absorb more heat than other areas, and some areas receive more direct rays (e.g. the equator) than others (e.g. the North Pole). The warm atmosphere gases then naturally move to colder areas, creating wind.

Some areas of the country are more suited for wind energy than others. If you live in the southeastern section of the United States, wind energy is not a good option unless you live in a high elevation or near a coastline. A wind resource map can be located on the web site listed in this article.

Another important factor in determining whether or not wind energy is a good possibility for your home is whether or not you are able to place a wind turbine at a high enough elevation to produce a cost-effective amount of energy. Most guides recommend wind turbine installation at an elevation of 30 feet higher than the surrounding area. The higher your wind turbine, the more energy it is going to produce. Of course, this also means that initial installation costs will be higher as well. Overall, wind energy is a great way to reduce your carbon footprint. Just make sure your location is well suited for it.

Conclusion

It can be a very satisfying experience knowing that you are saving money and reducing your carbon footprint every time you see the wind blowing or the sun shining. With the federal government basically picking up 30% of the tab through tax credits, now is a great time to invest.

Present-Day And Future Alternative Energy Sources

Alternative Energy Sources

The major past energy sources have included petroleum and coal. With the sharp increase in energy prices, depleting non-renewable sources of energy, the increase of green house gases impacting global warming, the future of using alternative 'green' sources of energy looks bright. Governments around the world are feeling the pressure of consumer demands for alternative renewable energy sources that will not harm the environment.

Wind Power is one method of producing 'green energy' that is becoming popular all over the world. Wind turbines are used to create power. Wind turbines can be placed wherever there is sufficient amount of wind. The higher the number of installed wind turbines, the more electricity will be produced.

Solar energy is one alternative energy source that is expected to see an increase in use in the future. This form of energy makes use of the sun for power and heat. Solar panels harness the power of the sun without polluting the planet and atmosphere. The solar panels power generators provide the electricity. The solar panels are installed on the roofs of residential and commercial buildings. In the future, larger solar panels will be built that can power hundreds of thousands of homes Solar energy requires does not require any other energy source to operate and it is free of pollution. Sunlight can be harnessed as usable heat or converted into electricity using photoelectric cells, solar panels, or using synchronized mirrors called heliostats that follow the sun as it moves. Methods for using solar power to replace a gas-powered engine by heating hydrogen gas in a tank have also been developed. There have been positive results with powering a generator.

Hydro Power is another alternative energy source with proven results. The flowing water drives the turbines which produces the energy. The energy created is dependent on the strength and force of the water flow because rapid flowing water drives the mechanisms that help with producing electricity. The current is then sent through a transformer where the electricity is transmitted over power lines. This is an eco-friendly form of energy and in the future, it is expected that more hydro power stations will be erected where there is a suitable water supply.

Current technologies for new renewable green energy sources, particularly solar power and wind power, are proving to be quite promising for the future. As well, Geothermal Energy which is heat energy extracted from the earth to create steam to power the generators that produces the electricity, is another potential future large energy source. There is also much research and development going into Nuclear Fission. Salinization of water at river estuaries as an energy supply is another possible source of alternative energy because many experts suggest that it will be millions of years before there is any impact. Nuclear fusion and artificial photosynthesis are two other energy technologies currently being researched as possible future energy sources.

Much of the traditional sources of energy are becoming unsustainable making new greener sources of energy the wave of the future. Many corporations, 'green' entrepreneurs, and governments are investing in the future of the planet and its inhabitants by investing in alternative renewable energy sources. An investment in 'green' energy means a future of low energy costs and a greener sustainable environment.

Cost Effective Alternatives For Energy

Alternative Energy

Solar energy has been used by man since the beginning of time to cook or dry food, warm dwellings and heat water among others. Today solar energy is used for heating structures, lighting buildings, heating water, solar powered electricity and a few brave souls try to power their vehicles this way.

Biannually there is a solar-powered car challenge, where mostly universities and enterprises compete. This has advanced the technology for solar cars, in 2007 the winner had an average speed of almost 57 miles and hour. Not bad over an almost 1900 mile course. Solar costs are often rebated by governments on a local or federal level to entice people to convert to solar energy. Up to 30% of total installation of solar hot water or solar electrically can be deducted from taxes as credits.

Biomass is made of anything that burns; garbage, paper products, dead trees, yard clippings, saw dust. California alone produces 60 million tons of biomass each year which if converted could run the electricity for two million homes! That's worth thinking about. The biomass is collected and burned in giant furnaces which are used to head water in a boiler the energy from the steam turns generators and turbines. This is a great way to reduce land fill and make energy which is clean and uses unwanted materials.

Wind energy is clean and efficient as long as the wind blows. A 10-kw wind turbine generates enough power to run an average household and a 250-kw turbine can run an elementary school for a year. Clean and efficient but almost always needs a back up plan in the event of a calm. Unfortantely these turbines or "wind mills" are very expensive to purchase.

Water produces electricity by quickly flowing or falling, the water rushes through a power plant and with the use of turbines and generators the energy in the water is used to produce electricity. Clean and efficient with moderate to high amounts of useful energy compared with low operating and maintenance cost. All kinds of clean natural resources are available but with our constant need for more and more energy we have to use explore all available alternatives.

Solar Panels

With the cost of electricity going up, the importance of talking about a renewable energy source is also gaining popularity among people, all over the world. With that said, here are some interesting facts about solar energy.

Solar Power Fact # 1:
The most thought provoking idea about solar energy is how little of the energy creation on the planet, comes from the sun. Only 0.1 percent of power comes from energy through the sun and is converted into electrical current. If there were more people who would install solar cells in their homes and cars, solar energy could cover more than the Earth's power. Everything would be covered, even needs for transportation and housing.

Solar Power Fact # 2:
Another interesting fact about solar energy is how much it's worth and how much money can be saved using it as a source of energy. If your roof is 1000 square feet and you install solar panels, you could potentially save as much as 6,460 dollars a year, over the cost of oil heating. The downside though, is that the initial investment will cost you between $20,000 and $50,000 to install; however there are tax incentives which offset the cost.

Solar Power Fact # 3:
One more of these interesting facts about solar energy, is that China is working with the United States to build entire communities which are created and powered by renewable energy resources. Homes are being constructed out of straw bales and are powered with solar and geothermal heating. Giving the size of China's population, the pollution problem has increased the development of renewable fields. Its hope is for the Chinese people and its country, to become more efficient and less costly.

With these interesting facts about solar energy, we see why it is becoming more and more important.

Resources For Alternative Energy

Resources For Alternative Energy

There are many different forms in which alternative energy is available.

One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar energy power can be used for electricity, heating, and making hot water. Solar energy produces no pollution, as its input comes completely from the sun's rays.

However, much more work still needs to be done in order for us to economically harness the sun's energy. For the time being, the resource is a little too conditional—storage batteries are needed to be used as backups in the evenings and on inclement days.

Wind energy has become the most-invested-in (by private investors and governments together) alternative energy source for the time being. The great arrays of triple-bladed windmills are being placed all over as “wind farms”, to capture the motion of the wind and use its kinetic energy for conversion to mechanical or electrical energy.

Of course, there is nothing new about the concept of a windmill for harnessing energy. Modern wind turbines are simply are more advanced variations on the old theme. The drawback to wind energy is...what do you do when there is a calm, still day? Needless to say, during these times the electric company kicks in for powering your home or office. Wind energy is not altogether independent.

Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. Simply put, hydroelectric energy uses the motion of water—its flow in response to gravity, which means downhill—to turn turbines which then generate electrical energy.

Needless to say, water is ubiquitous; finding sources for driving hydroelectric turbines is, therefore, not much of a problem. However, hydroelectricity as a source of alternative energy can be complicated and expensive to produce. Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power.

Building a dam to store and control water's potential and kinetic energy takes quite a lot of work, and operating one is complex as well,and conservationists grow concerned that it. Of course, a dam is not always needed if one is not trying to supply the electrical needs of a city or other very densely populated area. There are small run-of-river hydroelectric converters which are good for supplying neighborhoods or an individual office or home.

Probably the most underrated and under-appreciated form of alternative energy is geothermal energy, which is simply the naturally-occurring energy produced by the heating of artesian waters that are just below the earth's crust. This heat is transferred into the water from the earth's inner molten core.

The water is drawn up by various different methods—there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. The purpose of drawing up the hot water is for the gathering of the steam.

The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields; it's an example of a dry steam plant.

Renewable Energy

Just like many other global subjects, the present environmental situation is one of those topics which are SEPs or 'somebody else's problem' - to borrow a phrase from Douglas Adams. Whether the size of the task is so big that we are just not able to understand the full implication, or whether we feel that our little efforts will have such a tiny impact on the global situation that they will be worthless is hard to say.

However, if we all take on board the responsibility for making sure that we no longer waste so much of the planet's resources, then together we can ensure a more positive future for all of us. One way to reduce our carbon footprint is to convert to renewable energy where possible. If we as individuals take the decision to reduce our own carbon footprints then this equates to an impact on a global scale.

A great example of an individual who has started to use renewable energy is that of a farmer, who, rather contrarily, grows tomatoes all the year round in several giant heated greenhouses. Now, on the face of it, there is one individual who is going right against nature and using up a lot of resources for his own personal gain. Not a bit of it!

He has employed some unique lateral thinking and has actually adapted his whole farming technique so that he uses completely sustainable energy. He gets tons of fruit and vegetables which are thrown out by the local supermarkets and ferments them in giant slushy containers. A high-technology plant is used to trap the resulting methane which is burned to provide the extra heat needed to heat his greenhouses.

"But what about all that carbon dioxide?" I hear you techno-savvy readers cry. "Isnt that one of the main culprits of global warming?" Well, it is true, that burning methane (CH4), does produce a lot of CO2. He uses this extra carbon dioxide by-product to help his tomatoes to grow. He pumps it into the greenhouses to help them photosynthesize. The growing plants turn it back into oxygen.

This is just one example of someone who has given a few moment's thought and turned a huge scary problem into a neat solution. Just think of the alternative. Year-round heating of huge glass-framed structures; buying imported CO2 -it makes you shudder to even think about it!

We are all searching for ways to lessen our impact on the environment and do our bit for the planet. The best ways to achieve this are by taking small steps and doing things that are achievable and realistic.

"Free Energy — The Race to Zero Point" is an eye-opening account of free energy technology — why we don't have it yet, and what is being done about that."

Free Energy - The Race To Zero Point

Solar Renewable Energy - Sun Power



It is no secret that the sun can be harnessed to provide a source of energy for homes and businesses.

The sun is a powerful star. It supplies us with energy, through a process called nuclear fusion, and sustains life on our planet Earth. Solar energy, or energy from the sun, has existed since prehistoric times when men would magnify the sun's energy in efforts to start fires.

The sun is a valuable resource that radiates enough energy on the United States in one day to meet the nation's needs for one and a half years. Since it is a free, clean and renewable source of energy, it is an energy source that will play a vital role in our future.

Using the sun's energy for our energy source seems like an easy solution to having an energy supply forever. Harnessing the suns energy is where the problem lies. The sun's rays shine all over the world and not in just one spot. Although it takes only 8 minutes for sunlight to travel to the earth, trying to catch the rays over such a wide area can prove to be tricky. Also, the energy in any one given place will vary due to factors, such as, clouds and weather conditions.

The history of using solar energy began in 1890's when solar water heaters were used in the United States. Solar water heating requires a storage collector and a storage tank. Flat plate solar collectors are mounted on rooftops. Pipes carrying water are pumped through these collectors. The tubes are painted black so they will get hot quicker. As the heat is collected the fluid in the tubes get heated. A storage tank holds the hot liquid. This helps with central heating and cutting fuel costs. Solar heaters became popular when natural gas was expensive and burning wood and coals were burdensome. It's popularity diminished with the discovery of an abundance of natural gas and oil deposits. Now they are making a comeback to replace the depleting fossil fuels that had taken its place.

Solar energy can be in the form of heat energy or light energy. The technology of photovoltaic, or PV as it is commonly called, converts the suns energy into electric currents through the use of solar cells. These electric currents can be used instantaneously or stored for later use. The PV cells consist of pieces of silicon under a thin piece of glass. They have both a positive and negative charge. Simple examples of this are the solar powered calculators that are common today. More complex examples are solar panels placed on roofs. This consists of using thin film solar cells as rooftop shingles, roof tiles, and even glazing for skylights. Unfortunately, the cells generate only about one sixth of the sun's energy into electricity. This means bigger arrays are needed and along with this come larger costs.

Solar thermal power plants use the sun to heat fluid, which in turn, is transferred into steam similar to fossil fuel burning plants. The steam is transformed into mechanical energy in a turbine and electrical energy from a generator. The downfall is solar plants cannot produce energy on cloudy days.

It is expected the next few years will see millions of households using solar energy. As research continues and processes improve, using our sun as a renewable energy source will produce efficiency and cost savings. So, let the sun shine in and take full advantage of this warm energy source where you live.
