Dear our beloved crying planet…
Dear our beloved crying planet… I read an article last week in “The Gazette”, a local English paper here in Montreal Canada. It was titled “Time is running out” and was written by Peter G. Brown. He is a professor in the school of the Environment...
Energy Saving Windows
Windows are one of the great energy-wasters of any house. About
25% of the total heat loss is from traditional double glazed
sealed windows. New technology, however, has resulted in more
efficient energy saving windows that can significantly cut...
Experience the Thrill of Eagle Watching
"Above all other birds it is the soaring eagle, with its size and weight, that gives the most abiding impression of power and purpose in the air," declared Edwin Way Teale in Atlantic Monthly in 1957. Unique to North America and revered for its...
Oil Forever ? ( I think not )
Oil Forever ? We all know that this country needs to reduce
its dependency on Foreign oil. The question is how (and how
long). Recently Ford Motor CEO Bill Ford addressed his concerns,
perhaps leading one to question how long it will be...
Solar Cooling - Air-Conditioning From the Sun
At first glance, solar cooling looks like an oxymoron. However,
the same energy that can provide heat in the wintertime can also
provide cooling during the summer.
Several passive cooling systems have been developed and tested.
At their...

Advantages and Disadvantages of SOLAR ENERGY
Many of us know that solar energy is good, but few really understand why.
Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU.
Solar Energy Advantages
1. Saves you money
- After the initial investment has been recovered, the energy from the sun is practically FREE.
- The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
- Financial incentives are available form the government that will reduce your cost.
- If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering.
- It will save you money on your electricity bill if you have one at all.
- Solar energy does not require any fuel.
- It's not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of gasoline.
- The savings are immediate and for many years to come.
- The use of solar energy indirectly reduces health costs.
2. Environmentally friendly
- Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
- It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generations does.
- Therefore Solar Energy does not contribute to global warming, acid rain or smog.
- It actively contributes to the decrease of harmful green house gas emissions.
- It's generated where it is needed.
- By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.
3. Independent/ semi-independent
- Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage.
- A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective than the supply of utility electricity to a new site.
- The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or
When Money Was A Dirty Word
Fifty years ago, unless the family was playing Monopoly, parents didn't talk about finances with their children. Parents didn't even talk about money with each other. Now it's all people talk about. What happened?
Sec. Paulson Defends Bailout
Treasury Secretary Henry Pauson is defending the $700 billion bailout on Capital Hill Tuesday. Meanwhile, the question of whether automakers will get more government money, hangs heavy in the air.
international events and so contributes to a sustainable future.
- Solar Energy supports local job and wealth creation, fuelling local economies.
4. Low/ no maintenance
- Solar Energy systems are virtually maintenance free and will last for decades.
- Once installed, there are no recurring costs.
- They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.
- More solar panels can easily be added in the future when your family's needs grow.
Solar Energy Disadvantages
- The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.
- The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.
- Solar panels require quite a large area for installation to achieve a good level of efficiency.
- The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.
- The production of solar energy is influenced by the presence of clouds or pollution in the air.
- Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. See www.dsireusa.org for details on how net metering allows you to save electricity and money.
- As far as solar powered cars go - their slower speed might not appeal to everyone caught up in today's rat race.
