Hi!
Folding@Home is a nice idea. You can process data for research on your computer. But how efficient is it in terms of energy consumption? Sending data around the world, process it while keeping unused hardware idle and return the results. If the computer is running anyway it makes sense to me (even if it still uses more energy) but I believe to preserve our planet is more important than science. I believe this as a scientist-to-be. I may be wrong.
