Among the many measures the world can take to wean itself off fossil fuels, few match the benefits of making homes, business, and cars more energy-efficient. But financial and psychological barriers have kept individuals, businesses, and governments from realizing efficiency’s great potential.
The keystone of the green economy is a drastic increase in energy efficiency. Increasing our societies energy efficiency is the single most vital and important thing we need to do in order to have a green economy or in fact any kind of economy at all. It is also vitally important to throttle back the amounts of fossil fuel we burn in order to mitigate and diminish the rapid and potentially catastrophic climate change that is being driven by our fossil fuel habit.
Without much more energy efficient buildings and transportation systems nothing we do will be able to prevent an economic collapse brought about by the inevitable and rapidly approaching decline in the recoverable supplies of all forms of fossil energy. We cannot build out wind, geothermal, biofuel, or solar energy fast enough to sustain our civilization in the face of rapidly shrinking recoverable fossil energy reserves; unless we embark on an urgent and sustained drive to use energy (and other resources) with much higher efficiency.
Promoting the widespread use of energy efficient lighting is one of the best strategies available to increase our energy efficiency and reduce our carbon footprint. Around 25% of the electricity we consume is consumed to light our homes and buildings. Both LEDs (Light Emitting Diodes) and Compact Fluorescent Lights (CFL) use far less electricity per lumen (which is a measure of the amount of light produced) than do incandescent bulbs.
