On a clear, sunny day, the sun radiates about 1,000 watts of energy per square metre on the surface of the earth.
The UAE enjoys perpetual sunshine and endures temperatures exceeding 50 degree Celsius in the summer. It is not surprising then that in one year, the amount of solar radiation here is estimated to hit around 2,200 kilowatt-hours per square metre, the second-highest in the world. That is enough to power 2,200 pieces of 100-watt light bulb for 10 hours.
Now, imagine if you capture all of that energy, you could simply power your home or office without paying the electric bills. Then you could stop polluting the earth, reduce your eco-footprint and save money.
In other countries, where the flow of oil from the Middle East has thinned to a trickle, consumers have powered their homes with solar cells or panels on the roof. The Solar panels convert sunlight into electricity.
There are a number of reasons consumers are shifting to solar energy. Spiralling electricity bills and falling oil supply are on top of the list.
Doing a bit for the environment is a major factor as well. Energy from the sun is clean. It doesn’t pollute. On the contrary, the use of oil and coal to produce electricity increases emission of carbon dioxide and other greenhouse gases into the atmosphere.
Sustainable source
Another key word here is sustainability. Solar energy is a lasting natural resource. Unlike oil or natural gas, solar energy replenishes itself, so a dwindling supply is the least of worries.
The 2008 BP Statistical Review of World Energy noted that the UAE had the highest oil consumption growth rate in 2007. The trend is likely to continue, considering the country’s strong economic growth.
Although the UAE was the second largest oil producer in the GCC last year, signs of a dwindling supply are evident. In fact, oil production in the Middle East alone has recently dropped by 1.8 per cent to 25.2 million barrels per day.
The UAE may be major oil producer in the GCC, but there is no guarantee that its oil wells will flow forever. Reducing its reliance on oil and exploring other alternative sources should be a step in the right direction.
Besides, the sun shines eternally on this side of the planet. It would be a shame not to tap it. Just imagine the amount of energy produced if the roofs of all buildings are fitted with solar panels. Building owners will not only be energy self-sufficient, they will help reduce carbon footprint and save energy, as well.
Cost efficient
Experts say a residential solar panel can save about 2,000 to 4,400 kilowatt-hours of electricity over its lifetime. Although researchers have found that the cost of installing panels is about 2.5 times the value of the electricity produced, the long-term benefits far outweigh the capital cost.
The good thing is, according to some studies, solar panels need minor upkeep and the initial capital cost can be recouped within a few years. After that, energy becomes practically free, as the only financial cost to shoulder will be for periodic maintenance, which requires little money.
