Switch do greener energy
It is one of the easiest steps into a greener future. Just call your energy supplier and ask for green energy.
You leave a room? Just switch of the light. Thats quite simple. But you also can save energy while you are driving. Keep an eye on your tire-pressure. If it is to low, you need more energy
for the same distance. If you do not have a car or you just love to sit at home, there's also a possibility. Turn the heating a bit down and wear a nice pullover at home. It is not necessary to
sit at home during the wintertime with a t-shirt. It saves energy and money - awesome, isn't it?!
