Energy efficient light bulbs…. Are they better for the environment

Compact florescent light bulbs (CFLs) have been popularized for their money and energy savings and thus they are better for the environment. But is this really true?

I have found that many are unaware that these CFLs actually contain mercury, actually 4mg on average. You may not think that 4mg is much but try ingesting that and see what happens (please don’t try this and you will most likely die).

Well the problem lies in that fact that this mercury is getting back into the environment. How do you and most others dispose of these bulbs? You throw them in the rubbish, which ends up in land fill. Then the mercury leaks in the ground and eventually into the ground water.

Are we poisoning ourselves and the environment by using these CFLs? Of course we are and I am shock to find out how many people actually know this.

There are better ways to save money and save the environment.


One way is through the power of the Sun. Solar panels have become much cheaper and more powerful. You can run your entire house off solar energy. With a short term investment you can make a huge long term saving in both money and the environment.

  1. You don’t throw them in a landfill! You recycle them, as you should recycle EVERYTHING ELSE you’re able to. You show a complete lack of environmental awareness with your statement. It is possible to have tiny amounts of household refuse ending up in a landfills, nothing more if you truly make an effort. As to the mercury argument, there’s less mercury inside each low energy light-bulb than would be directly emitted into the atmosphere by a coal-fired power station producing the extra electricity required by a traditional bulb. So in fact low-energy light-bulbs can theoretically reduce atmospheric mercury levels. And, of course, because they consume so much less energy and much more highly efficient, the CO2 emissions are much lower than power-hungry traditional bulbs. As to solar, of course that’s where we should be heading, but do not discount the incredible value of CFL bulbs.

    • What percentage of people do you think recycle these bulbs? It’s less than 10%, so more than 90% currently goes into landfills. You are right, it takes little effort to recycle them but why use them to start with. There are energy efficient bulbs available that do not contain mercury however they are not widely available, why? More suppressed technology, but what is their reason for this? Maybe they want more mercury in the environment?

      I think Solar is the way people should be going. Just be careful of these government grants that offer money if you install solar panels – it’s a con. You have to use their “approved” supplies, who by the why charge more and you are also required to connect to the grid and you solar power is feed back into the grid. You can get better deals that the government approved suppliers and no conditions attached.

  2. If you’d like to know where to recycle your CFL’s, contact your local council. Many high street shops now also allow for collection in their stores.
