One Billion Bulbs

One Billion Bulbs
Imagine if people all over the world mobilized to replace one billion standard incandescent light bulbs with energy-efficient compact fluorescent (CFL) light bulbs. What would that mean? It would mean that those people would save money each month on their electricity bill. It would make a difference to the environment - preventing greenhouse gases equivalent to the annual emissions of millions of cars. And it would reduce our energy dependency on other countries and on fossil fuels.
