The other problems I see is that humans don’t seem to be interested in producing their own energy . Take a windmill for example . It isn’t a very sophisticated piece of machinery , and you can make one in an our out of old electric motors or an alternator from a car . The other great resource is of course the sun , and if everyone used their roofs to make energy just imagine how much energy that would make . Take a look at our power grid system don’t you think many of those towers holding the lines could carry some kind of windmill on it ? I hear the wind whistling through those wires way up high and I can’t help but think of how much energy could be made . I think we have to look at the way we’re doing things and try new ways cuz the old ways are KILLING us !
