How Much an Energy Saver Saves?

A light bulb is a very simple and often overlooked factor in the estimation of total energy consumption. We do not think that a bulb can have some effect on the amount of energy consumed in our homes. But this is not true. Reports show that these small bulbs cover 10% of our energy daily consumption of energy. The Environment Protection Agency reported the by replacing one incandescent bulb with one LED light in every home of the city, the nation eventually saved about $ 600 million per year in energy cost.

This report opened the eyes of many individuals as well as many higher officials and they start thinking seriously the replacements of common, old tradition bulbs with energy savers. On the other hand, this report acted as a stimulant for the companies that make energy savers. They started applying new technologies in the manufacturing of energy efficient products and this made a revolution in the field of technology.

There are mainly two types of energy efficient lights. One is compact fluorescent light bulbs and the other is LED bulbs. Fluorescent bulbs were in use for the last many years but they do not have energy efficiency power. They consume more energy and produce less light. Their comparatively new version is compact fluorescent bulbs (CFL). They are easily available in the market and they are not very costly. They are easy to replace and found in a wide range of variety in shapes and colors.

LED is the short form of light emitting diodes. In LED lights these light emitting diodes are used that are energy efficient and environment friendly. These lights are a newer option for residential lightings though they are very old as they have been in use in Christmas lights for a number of decades. They are more energy efficient than other energy saver lights.

When we compare these energy savers with each other, we find that LEDs are more energy efficient than CFLs. CFLs use one fourth of the energy of standard incandescent bulb whereas good make LEDs save one tenth of the energy used by incandescent bulbs. CFLs have a lifespan of 10,000 hours and LEDs have expected life span of 50,000 hours. The lifetime electricity cost of CFL bulb is $ 28 for 10,000 hours and the lifetime electricity cost of LED bulb is $ 60 for 50,000 hours. The LED bulb saves 400 kilowatt hours of electricity as compared to CFL. This represents the cost savings of $ 80 over CFL bulbs. Is not it a remarkable saving?
