Mr. Turnbull said that the switch in lighting technology would reduce greenhouse gas emissions at an annual rate of around 8000,000 tonnes to 2012. But this could rise to as much as four million tonnes a year by 2015 as more households and industry make the change. Lighting represents a large portion of greenhouse gas emissions in Australia - around 12 percent of household emissions, about 25 percent of commercial sector emissions, and 25 percent also of public and street lighting emissions.
Wal-Mart is trying to instigate a similar revolution in the U.S. through its scheme to sell every one of its regular customers--100 million in all--one compact fluorescent bulb.
Analysis: We have much better things to use our electricity on, such as PHEVs and pure EVs. Why blow our energy on 19th century technology when we can use 20th century instead? And one day we might even see the widespread adoption of white LEDs that will save even more juice.
