The extended colder weather has pushed up natural gas prices—reflecting price rises we’re seeing at the gas pumps. With some electricity generation shifting toward natural gas, we’ll continue to have demand pressure, even as more supplies are found. Add to that, the fact that the pipes are only so big, and we can only squeeze so much natural gas through them. This is part of the reason we saw natural gas shortages in several states this winter. And it’s not going away. Even with more supply of energy—gas, electricity, oil—we would still have an expensive distribution problem. New electric lines, and bigger gas pipelines aren’t free. The cost gets reflected in the energy bills we pay. However, by increasing efficiency, we help solve both the supply and the distribution question. Individually and collectively, we decide where our money gets spent. To me, it just doesn’t make sense to burn it when there are so many other things we could be doing! And that’s why energy-efficiency makes sense. And cents. And lots and lots of dollars.
