Solar Power: a Solution for Pollution

Print Friendly

More and more people are looking to find an alternative source for fossil fuels; Solar power is a popular choice for that job.

There are many devices that can collect the su ‘s beams; like a Focusing collector and a Flat-Plate collector. A Flat-Plate collector uses tubes filled with liquid to absorb the heat. A Flat-Plate collector and a Focusing collector work for converting solar energy, into thermal energy. A Focusing collector uses a reflector that focuses the sun’s beam’s onto the middle ball that absorbs the heat. Sadly, it is harder to convert the sun’s energy into electrical energy.

Solar power has many advantages. One of the great advantages are that once you install one you don’t need to pay Hydro bills. Another great pro is if you produce more power then you need you can sell it to Hydro for the exact same price that you would normally pay.¬† Solar power creates no pollution except the materials needed to make it. Once you purchase one you don’t have to rely on the fossil fuels supplies for electricity.

There are many advantages, but there are also cons. Solar power is way more expensive then any other source. Ex: It costs about $1000 for one device, and some houses may need more then one. If the United States decided to replace fossil fuels with solar power, it would cost 30 trillion dollars, and they would have to cover 25,000 sq. miles just to generate enough power. Even though it would generate power, it will use 500 times more materials thrn we would normally use.

Solar energy is one of many solutions for fossil fuels.
