Light Bulbs and the Environment

Light bulbs are so numerous and commonplace in homes and buildings across the world that cumulatively they have an enormous affect upon the environment in terms of energy usage and ultimately the method of how this energy is created/harnessed. The electricity required to operate the light bulbs of the world results in a significant demand for power which is still primarily generated through power stations which burn fossil fuels to create it. This results in a lot of pollution which is harmful to the environment as well as the health and wellbeing of life on earth.

What this also means though is that a small modification multiplied by so many light bulbs means that a change in attitudes and certain actions on such a large scale can have a dramatically positive effect upon the environment through using less energy and reducing the demand for electricity.

One such alteration is through the replacement of traditional incandescent light bulbs with energy efficient ones that use less electricity. Recent legislation to prevent older style light bulbs being sold in shops has greatly increased the use of energy efficient bulbs simply by removing any alternative, which as a consequence has reduced the demand for electricity from each light fitting.

Some bulbs are brighter than they need to be, and substituting them for lower wattage light bulbs will still provide an adequate level of light whilst consuming less power to do so.

Even better than low energy usage bulbs is no energy usage. Switching off lights in unoccupied rooms can reduce energy consumption, as does installing sensors which turn lights on when the movement of a person entering the room is detected, and automatically turns lights off when it has been empty for a certain length of time and no further movement takes place within. Whilst it will only make a slight difference to an individual in terms of energy and money saved, if everyone in the world did it the cumulative effects of not lighting up unoccupied rooms would have tremendously significant benefits for the environment.
