Energy Future Use

If you focus on the left hand side of this graph you can see how disproportionate is the use of energy by the less than 5 percent of people who live in the United States (who use most of the energy in North America). If you look at the right hand side of the graph you can see that the problem of greenhouse gas emissions is going to come primarily from other regions in the future. Climate change is not a major problem now, but if we in the United States are unwilling to economize on energy use now, how can we convince others we are serious in seeking a more energy efficient world in the future to prevent catastrophic climate change?
