In our third class, Byron reviewed all the energy-saving changes that have been made throughout the church building. The changes were motivated by the desire to save money on gas and electricity, but they also make a huge difference in our collective carbon footprint. Over recent years they include the use of compact fluorescent bulbs wherever the fixtures will accommodate them, LED exit lights, and zoned heating with accurate time controls so that we are only heating areas that are in use.
At the last class we reconsidered the carbon effects of eating meat, and looked at the difference among beef, pork, and chicken. An in the February 2009 issue of Scientific American shows that pound for pound producing beef contributes 13 times more greenhouse gases than chicken.
