Earlier quoted context omitted.
U.S. energy demand has actually fairly steady. It was slightly lower in 2014 vs 2008. http://www.indexmundi.com/g/g.aspx?c=us&v=81 A wide range of things have been getting more energy efficient TV, lighting, computers, heating cooling, insulation, etc.
It's good things are getting efficient up to a point however those kind of savings are unsustainable and in the longterm our energy use will continue to grow exponentially, including for environmental management. Thus it doesn't make sense to research power sources that aren't potentially 100s of times greater than our current usage.
Boring, pointless potatoes.
