One of my staff sent me the following story (news.com.au) regarding the banning of incandescent light bulbs and the increase in production of compact flurorescent lights.
I agree totally with Bjorn Lomborg when he speaks on solving the world's problems. Simply that is, fix the easy things first, and at least you'll make progress.
Bjorn proposes that taking steps to solving the AIDS epidemic in Africa is easier, cheaper, and has a bigger impact for the next generation than chasing hugely difficult problems like global warming solved through carbon trading and emissions controls. Just like the above article comments, a nation wide switch over to flurorescent tubes will reduce lighting caused emissions by 66%. While that may only be a 66% reduction on 9% of our national energy bill, that is not an insignificant amount.
And what's the trade off? Well, you'll have to screw in a different type of light bulb.
