True cost of lights bulbs
Last year the House of Representatives voted to withhold funding to enforce a law that was passed in 2007 and increases efficiency standards for light bulbs.
There’s a lot of misinformation out there about the cost to consumers of CFL and LED bulbs and the savings in energy and money that could be realized.
Let your students “do the math” and realize some of the profit that could be made by changing our ways.
