Energy Conservation Quiz



You can go to the National Geographic website’s Energy Conservation Quiz to find out just how much you know about carbon emissions and how to reduce them.  I scored an 88.  Try to beat that!  :)

Here's some trivia that might help you!

A Carbon Reduction Plan: The Savings
By investing in new technology or adopting approaches already available, we could cut worldwide greenhouse gas emissions by about 38 billion tonnes a year. The money saved from efficiencies in how we use energy could help pay for improvements in how we generate energy, optimize industrial processes and avoid deforestation.

Changing Bulbs
The light-emitting diode (LED) looks like the eco-bulb of the future. With no filament, just a microchip, it uses significantly less energy than an incandescent. But the price is high and reviews are mixed. LED illumination (in photo, center) can range from warm to what technology analyst Michael Kanellos calls "alien autopsy." The bulb casts its light in only one direction, which is fine for recessed lights and for spotlighting a specific area but could be a drawback in lamps or globes. In a few years, expect a cheaper, more versatile LED. Until then, experts recommend compact fluorescents (CFLs) for most home use—with a note of caution. Their mercury content calls for disposal as hazardous waste. —Linda Kulman

The average U.S. household produces about 150 pounds of CO2 a day by doing commonplace things like turning on air-conditioning or driving cars. That's more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses.
A gallon of gasoline adds a whopping 19.6 pounds of CO2 to the atmosphere, a big chunk of our daily allowance. A kilowatt-hour (kWh) of electricity in the U.S. produces 1.5 pounds of CO2. Every 100 cubic feet of natural gas emits 12 pounds of CO2.
