I've been thinking about this today, and I can't wrap my head around it.
The Bible says drunkenness and extra-marital sex are wrong, and Christians generally tend to avoid those behaviors, or at least agree that they should avoid them.
The Book of Mormon (I've been told) says that "hot drinks"--meaning coffee and tea--are bad and should be avoided, and the Mormons I know do avoid them. Many of them avoid caffeine altogether.
The Q'uran says to avoid alcohol (of the vine or the grain, according to The 13th Warrior), and devout Muslim do not drink alcohol.
Even outside of the realm of spiritual religion, people who believe that fast food is bad for them generally avoid it. Vegetarians avoid eating meat, and vegans (how is that pronounced, anyway?) avoid all animal products, including dairy, eggs, and animal oils used in foods.
So why is it that people who believe in Anthropogenic Global Warming (AGW) use electricity? Unless it's generated by nuclear or water power--both considered by many to be environmental hazards themselves--virtually all electricity is the result of burning fossil fuels. Isn't it hypocritical for people to use computers to write about how we should reduce or stop burning fossil fuels? What about going on television? I can't even imagine the power consumed by television cameras, studio lights, transmission towers, let alone all those big-screen plasma sets to tune it in. I'm not even going to mention those who travel the country, or the world, in gasoline or diesel powered vehicles and in jet aircraft, to rail against the very civilization that gave them those tools, for using those tools.
Why don't people who believe in AGW go live on a self-sufficient plot of land far away from electrical transmission lines? Maybe some Amish in Pennsylvania would be willing to sell part of their land.
