Electricity has become a necessity for human life. We use it to power everything from our homes to our street lights to our jobs. Although we need it in order to generate electricity, we end up putting a lot of harmful chemicals into the air through burning fossil fuels. Natural gas is in Cole's air, emitting toxic levels of carbon into our atmosphere that contribute to global warming. Climate change is a global issue that negatively effects us all. It can lead to stronger natural disasters such as droughts and hurricanes. Make the air we breathe deadly and caused the economy to lose millions of dollars. Not only are they dangerous, but fossil fuels air a limited resource. Once they're gone, there's no way of getting them back and will be left in the dark. The good news is there's a safer form of energy out there, and that's been supplying as power for us, long as we can remember. To put it simply, this energy comes from the sun. Specifically, solar panels harness energy from the sun and converts it into electricity in order to power homes and businesses. They do this by exciting electrons in silicon cells, using the photons of light from the sun. Most of the time, these panels are placed on the roof in order to get us much. Exposure to the sun is possible. Solar panels contribute to reducing climate change by reducing air pollution caused by utility companies. Using solar power creates peak load generating capacity, which saves utilities from using polluting supplemental systems during times when demands for energy are high. The more solar electric power systems in a general area, the less capacity of utility needs to build. This ultimately saves money, creates jobs and gives the area clean green source of energy. Solar energy is a resource that's been fueling the planet for centuries. Now we can use it to power our homes and help keep the planet clean and safe.
