In 50 years, how do you see energy use changing in the United States? Q/A 5

In 50 years I see energy use changing in the United States a lot.  We have already made huge strides in saving energy in the United States just think in 50 years what we can accomplish.  I also see some of the energy uses that are not the most popular ones like hydropower and wind power coming into play and being used more.  I also see us being way more energy efficient with turning lights off when we dont have to use them.  Also I can see schools teaching kids at a younger age about how being efficient is helpful to the environment and telling them ways to be efficient and things to do.  Also I can see prices going up and it costing more to use energy because there will be new uses that will cost more to keep them running.  These are the things that I think will change energy use in 50 years.
