Both saving energy and protecting our enviroment / planet have a lot in common and will require us to change our lifestyle and habbits. It won't be a few big changes but probably many smaller changes which will be needed and maybe this energy crisis has been a wakeup call to put the brakes on our wasteful energy usage. The modern lifestyle is highly energy dependant and everything we do causes energy to be used somewhere, to get water into our homes is using electricity, to get the waste out and treated uses more energy and maybe many don't see the bigger picture.
