18. Incandescent Light Bulbs
Is the world getting less bright? Throughout the globe, the once standard incandescent light bulb is being put out. Cuba became the first nation to completely ban incandescent light bulbs and switch to the dimmer yet more energy-efficiant fluorescent light bulb.

Venezuela, Brazil and Australia have also imposed similar bans.
In America and the European Union, the phase-out is ongoing. In 2007, the US Congress passed legislation that would require all light bulbs sold in the US to be 70 percent more efficient than those used in 2007. They would also have to produce a minimum of 45 lumens per watt. The EU phase-out launched in 2009.
