Solar Energy - Environment
With the environment of the planet in peril and the demands that are placed on the environment increasing, the need for green, clean and sustainable forms of energy is all the more critical. There is plenty of evidence to show that the processes to derive fossil fuels are environmentally harmful and so traditional sources of power for our homes, businesses and communities are no longer appropriate by virtue of the dangers that they present for humans and the earth.
Such a scary reality has given rise to increased awareness of the need to generate and supply electricity in safer and more environmentally friendly ways. Solar energy presents a wonderful alternative to more environmentally damaging forms of electricity.
The U.S. Department of Energy states that fossil fuels, which generate electricity through burning, produce about two-thirds of sulfur dioxide emissions and a quarter of nitrous oxide emissions in the United States, causing smog and acid rain. In 2007, over 8 billion metric tons of carbon dioxide were released into the atmosphere, which is believed to contribute to man-made global warming and climate change. By contrast, solar panels produce no emissions during their operation. Solar energy is converted to electricity without any material byproduct.
Creating energy is a water intensive process. In the U.S., electricity production accounts for more than 40 percent of all daily freshwater withdrawals. Solar photovoltaic systems do not require any water to generate electricity.
