The Problem with Energy Efficient Light Bulbs
While Energy efficient light bulbs (also known as a Compact Fluorescent Lamp, or CFL) help address one environmental issue, they cause another. Fortunately, the later can be addressed quite easily - as long as governments make it easy.
The Benefits of CFLs
Energy efficient light bulbs are being encouraged by green groups, electricity providers, and governments around the world, and for good reason. For the same light output, an energy efficient light bulb uses between a fifth and a quarter of the energy that a traditional light bulb (also referred to as, incandescent lamp) uses.
And what’s more, over it’s lifetime, an energy efficient light bulb can save over 2000 times it’s weight in greenhouse gases.
But, like so many environmentally friendly solutions, there is a dark side to energy efficient light bulbs.
The Problem with CFLs
Each energy efficient light bulb contains a small amount of mercury. In fact all fluorescent lamps contain mercury, and energy efficient light bulbs are a form of fluorescent lamp . The amount of mercury is usually quite small - around 5 or 6 grams.
The problem with mercury is that, if it’s not disposed of properly, it will lead to air and/or water pollution. Currently, most CFLs are dumped into landfills or incinerators. This is because people simply through them in the bin when finished with them.
How to Address this Problem?
The simple solution is to recycle your CFLs and other fluorescent lamps.
Under normal circumstances, the mercury in each CFL isn’t an issue. As long as the light bulb is discarded correctly and doesn’t break before it’s discarded, everything will be alright. CFLs should never be thrown out with the normal rubbish. This is because it will end up in landfill. From there it could break and mercury will end up in surrounding waterways. Or it could burn and release mercury into the air.
Energy efficient light bulbs (and any other fluorescent lamp) should always be recycled. This obviously requires you have a recycling station to take it to. Ideally, local governments should provide education and easy access to these recycling stations.
For example, you should be able to simply throw your light bulb into a recycling bin at your home (which is separate from your normal garbage). You could place your recycling out on the street say, once per month (or more frequently). Then, a recycling collection service could pick up your recyclables as they drive past and take them to the recycling station.
Some governments are starting to become aware of this issue, but there’s still a long way to go.

[...] We could also make sure we buy energy efficient light bulbs. They use far less energy than traditional light bulbs and produce much less greenhouse gas. Although, if you do buy energy efficient light bulbs, just make sure you dispose of them properly. [...]

As energy prices sky rocket the prices of solar panels will only go up. This will hopefully prove that solar panels will be a great investment for anyone wanting to save some money or help the environment. Either way, solar panels really should be at the top of the “to do” list. Someone has recommended Solar Panels so I am really looking forward to getting them.
