The credit crisis could spark a rise in oil prices

Here’s the bad news about the global recession’s potentially coming to an end: the recovery could spark a massive energy crisis with increased demand for fossil fuels from China and other developing countries, tighter oil supplies and skyrocketing oil prices. And this is just in the near future. The longer-term picture looks even more daunting. If the world continues to guzzle oil and gas at its present pace, global temperatures will rise by an average of 6°C by 2030, causing “irreparable damage to the planet.”

What is the true cost of solar power? The answer to this question may determine whether or not you decide to install solar panels on your home or business. In fact, in the current economy, everyone is worried about investments, and whether they make sense long term.

How does the cost of solar power factor in?

In order to accurately determine solar energy cost, you’ll need to consider a range of factors. Get your pencil out… you should write these down:

1. Current utility bills, averaged on a monthly basis
2. Projected future utility bills, over your estimated years of ownership of the property
3. Amount you may save annually in electricity bills
4. State and provincial solar energy tax rebates and other incentives, such as no money down
5. Type of solar panel system you want to install: PV Panels or Solar roof shingles
6. Other potential energy savings, through energy efficient bulbs, shutting off lights, adjusting thermostats
7. Other potential energy retrofitting measures, including windows, insulation, Energy Star appliances, etc.

When you consider the fact that solar power is free, once you install the panels, it may be worth it to consider converting now.

Case in point

Let’s say that your solar panel system will cost you R20,000.  Now, consider that your monthly electricity bills average R600 a month, which is R7,200 a year. That alone would be about a 3-year return on investment, but wait! What about the increase in value of your home? If you can save the entire R7,200 a year, multiply that figure by 20 which is the typical loan period you get R144,000.   That’s right: R144,000 in additional property value!

Now, add in the rising electricity rates that you won’t have to worry about. Oh, and the cost of continued global warming – you are doing your part you know… priceless!

You see, it just takes some focused arithmetic to determine the true cost of solar power. Think beyond your initial investment/outlay, and I’ll bet you will soon see that solar energy is the way to go, without requiring you to break the bank.

Those in search of renewable energy or renewable energy financing should go and knock on First National Bank’s door.

The bank has just received the approval to disburse N$6 million, in a revolving credit guarantee scheme to solar energy technicians and rural communities in search of solar financing.

During the initial years of electricity distribution, Edison’s direct current was the standard for the United States^[1] and Edison was not inclined to lose all his patent royalties. Direct current worked well with incandescent lamps that were the principal load of the day, and with motors. Direct current systems could be directly used with storage batteries, providing valuable load-leveling and backup power during interruptions of generator operation. Direct current generators could be easily paralleled, allowing economical operation by using smaller machines during periods of light load and improving reliability. At the introduction of Edison’s system, no practical AC motor was available. Edison had invented a meter to allow customers to be billed for energy proportional to consumption, but this meter only worked with direct current. As of 1882 these were all significant technical advantages of direct current.

From his work with rotary magnetic fields, Tesla devised a system for generation, transmission, and use of AC power. He partnered with George Westinghouse to commercialize this system. Westinghouse had previously bought the rights to Tesla’s polyphase system patents and other patents for AC transformers from Lucien Gaulard and John Dixon Gibbs.

Several undercurrents lay beneath this rivalry. Edison was a brute-force experimenter, but was no mathematician. AC cannot be properly understood or exploited without a substantial understanding of mathematics and mathematical physics, which Tesla possessed. Tesla had worked for Edison but was undervalued (for example, when Edison first learned of Tesla’s idea of alternating-current power transmission, he dismissed it: “[Tesla's] ideas are splendid, but they are utterly impractical.”^[3]). Bad feelings were exacerbated because Tesla had been cheated by Edison of promised compensation for his work.^[4][5] Edison would later come to regret that he had not listened to Tesla and used alternating current.^[6]

In 1887 direct current (DC) was king. At that time there were 121 Edison power stations scattered across the United States delivering DC electricity to its customers. But DC had a great limitation — namely, that power plants could only send DC electricity about a mile before the electricity began to lose power. So when George Westinghouse introduced his system based on high-voltage alternating current (AC), which could carry electricity hundreds of miles with little loss of power, people naturally took notice. A “battle of the currents” ensued. In the end, Westinghouse’s AC prevailed.
