Thomas Edison is best remembered for inventing the incandescent light bulb. 125-years later his invention may be on the way out. What's wrong with Edison's light bulb is that it's terribly energy inefficient.
Australia, which is usually the source of global warming criticism, has announced that it may ban incandescent light bulbs and require they be replaced with compact, flourescents instead.
Legislation to restrict the sale of the old bulbs could reduce Australia's greenhouse gas emissions by hundreds of thousands of tons and cut household lighting costs up to 66%, Environment Minister Malcom Turnbull said. Australia produced almost 565 million tons of greenhouse gases in 2004, officials say.
