Pros & Cons Of Solar Energy

solar energy
Every day, households around the world are using up the planet’s resources for energy. If this continues, these energy sources will be depleted quickly -unless alternative renewable energy sources are utilized.One of the energy sources that modern technology has recently put to good use is solar energy. Solar energy isn’t anything new, but new technology advancements have placed solar power more into the mainstream, and it may one day be one of our primary sources of power.

Advantages of Solar Energy

Since solar energy comes directly from the sun, it is not only renewable, but also accessible in any part of the world. As long as the proper equipment is utilized, unlimited amounts of solar power can be collected and put to good use.

Solar power is also one of the cleanest forms of energy, since it creates no pollution, and produces no greenhouse gases or waste products. For residential uses, the use of solar power minimizes negative impacts on the surrounding environment, making it a safer alternative to wind or hydro power.

Not only is solar energy non-pollutant, in terms of gases, but it also causes zero noise pollution – since there are no moving parts in any of the devices which are used to capture the sunlight. Due to the fact that no moving parts are used, maintenance costs are low as well – only occasional cleaning and periodic battery replacements are needed. Most manufacturers of solar panels provide twenty-year warranties for their equipment, guaranteeing long-life operation.

Solar panels placed on rooftops also double as a heat absorbers, slightly cooling the top area of the house which is directly below the roof.

Disadvantages of Solar Energy

The most obvious drawback of solar energy is its sole dependence on the sun. Once the sun goes down, energy collection comes to a halt. Solar panels can also be expensive, because of the materials that are used to create them. And even when these materials are taken out of the equation, the entire process, considering the other devices involved, can be a bit costly.  But most of the cost involved is in the initial purchase and installation of a solar power system – not running costs.

What’s the Bottom Line?

More research and development continues to be invested into this growing technology, and that’s a good sign – as solar power may one day be used more frequently than other energy sources. Of course, solar energy isn’t perfect, but it makes a great complimentary addition to other energy forms.
