A simple Example of Energy Efficiency Concept
Energy efficiency is a very broad term referring to the many different ways we can get the same amount of work (light, heat, motion, etc.) done with less energy. It covers efficient cars on the roads, efficient ships in the waters, improved industrial practices, better building insulation and a host of other technologies. Since saving energy and saving money often amount to the same thing, energy efficiency is highly profitable and great contributor for the climate change issue. Energy efficiency often has multiple positive effects.
For a simple example, an energy saving light gives more amount of light by consuming less amount of electrical energy than a traditional light bulbs.Compared to traditional incandescents, energy-efficient light bulbs such as halogen incandescents, compact fluorescent lamps (CFLs) and light emitting diodes (LEDs) have the following advantages:
- Consume about 25%-80% less energy than traditional incandescent lamps.
- Can last 3 to 5 times longer, thus saving more money,
- 4 to 5 times less energy consumption and thus saving more energy. So, less fuel consumption and less emissions from power plants.
Today’s energy-efficient bulbs are available in the wide range of colors and light levels you’ve come to expect. While the initial price of energy-efficient bulbs is typically higher than traditional incandescents, newer bulbs cost less to operate, saving you money over the life of the bulb. Many of the newer bulbs last significantly longer than traditional bulbs, so you won’t need to replace them as often.
