Another divisive issue we face is energy – where we get it, who profits, how do we conserve it – all have proponents and detractors. Still, it is not necessarily a political problem for you, directly.

In terms of total usage, the United States consumes the most energy, while ranking seventh in per capita consumption. For the year 2005, we used 100 quadrillion BTUs , a staggering amount of energy, roughly 15.7 million Hiroshima style bombs. Estimates of the sources for this energy indicated that 40% comes from petroleum, 23% each from coal and natural gas. Nuclear power accounts for a bit over 8%, while renewable energy supplies just under 7%. The vast majority of renewable energy energy is hydroelectric.

There are four broad categories used by the U.S. Department of Energy to track national energy consumption. Our industrial sector has long been the country’s largest energy user, accounting for roughly a third of the total energy consumed. This is followed by the transportation sector, and then the residential and commercial sectors.

Regardless of which category impacts you, there is one thing to remember: energy equals money. Saving energy is not just about saving the planet, it is about saving your pocketbook. There are countless ways for you to approach this issue. One good one is to engage e426.org for an objective analysis of your particular situation.
