Perseverance is best way to describe my emotion behind these pictures.
I see the images of factories that help fuel the world. Places that allow the machine of world to keep on ticking. Every time you flip a switch you can thank someone that works in one of these factories. I see the greatness that man can attain by manipulating the earth and make something useful out of it. The beautiful thing is that new technology is being developed every year to make energy more efficient, safer, and cleaner.
I prefer pictures of Nuclear Power Plants over coal or oil. Since I believe it is the safest (Statistically it is), most efficient, and cleanest resource we have right now.
