Have you imagined life without electricity? I think it will be hard for all of us since almost all of our day to day doings depend on it. But it’s not free and we need to pay whatever we consumed. A couple of years ago I learned about solar panels. It has many advantages and expensive payment from electricity will never be a dilemma anymore. All we need is just the sun, when solar panels are pointed right at the sun they intercept the most light rays and voila electricity is now free.
