Eco Minute July 10, 2014
Regular incandescent light bulbs are inefficient, with 90% of their energy going to generate heat not light. Changing out just one frequently used incandescent bulb for a compact fluorescent bulb can save an average of $30 or more in electricity costs over its lifetime and prevent more than 450 pounds of greenhouse gas emissions.
If everyone in the county did that – it would save enough energy to light more than 2.5 million homes for a year and we would not have to build two power plants and it would prevent the release of greenhouse gases equivalent to the emissions of nearly 80,000 cars.
Trade out five bulbs and you’d save close to $8 billion each year in energy costs, and would prevent the greenhouse gases equivalent to the emissions from nearly 10 million cars or even better change out all your light bulbs.
