Energy saving light bulbs are a big thing in today’s world. Australia is working on phasing out the regular light bulb and replacing it with the energy efficient variety. Environmental Minister, Malcolm Turnball, was the one to introduce the measure. Environmentally friendly light bulbs cost $5 more than regular bulbs, however they save households a median of $30 over the life span of the bulb. They are 80% more efficient than regular light bulbs and can last up to ten times longer.
