When you go to Washington D.C., for whatever reason, what comes to your mind visiting as a tourist? The White House; in other words, it would be known for President Obama and his family's living quarters. Haven't you ever wondered where his supply of electricity and heating come from? In the year of 2011, Obama himself had installed solar panels on the rooftops to save electricity that rises up to an estimated amount of $2,300 on average for every month. By the help of solar technology, the President has invested $100,000 towards solar panels; however, over the long run, he would be earning back the amount he invested in the next 5 years in electric bills.
Here is Obama spotted on the rooftops of the White House supervising the installments of his solar panels.
