The Muscle Car Of Energy Efficiency
By Tom Konrad
The poster child of energy efficiency has long been changing a light bulb. First, it was swapping out an incandescent for a compact fluorescent, now the swap is to an LED. Changing a light bulb is a small step that anyone can take, and it’s so cost effective that it can pay for itself in months if the bulb is used frequently.
This is a good example of household energy efficiency measures: a small action requiring a limited investment that anyone can take that pays back quickly.
But efficiency does not have to be small scale and simple. Efficiency can also be an industrial scale engineering project. At any scale, however, it tends to be profitable, often very profitable.
