save money

In a recent article I described how a detailed analysis of energy production and usage in the US shows that about 51% of the energy produced is wasted. One of the best ways of addressing our energy problems is energy efficiency. True, we need to do more: carbon sequestration (saline wetlands and trees in all but the northernmost latitudes are the best ways of sequestering carbon) and alternative energy are necessary. But even without changing our energy production, we can get a good head start on dealing with global warming by improving energy efficiency. In John and Teresa Heinz Kerry's book, This Moment on Earth, they describe how Texas Instruments was able to design a factory in Texas where energy efficiency was the primary design element that saved them so much money that it allowed building in Texas to be competitive with outsourcing to India. They saved money, saved energy and kept jobs in the United States all by designing with energy efficiency in mind.

Energy efficiency is the smartest step towards dealing with global warming.

There are many ways that you as a private citizen can be part of the solution. Carpooling, using mass transit, bicycling, walking, buying a hybrid car, turning your thermostat down a degree in the winter, and up a degree in summer, turning off lights, insulation, etc. are all ways where YOU can both save money in the long run and save energy. They all make sense both for your budget AND for dealing with global warming. You should do all you can to do these things. But there is one that is such a no-brainer, that if you haven't already done it, you are losing. The number one change you should have made at least 5 years ago is to switch your light bulbs to compact fluorescent bulbs.
