We should remember that the energy we use has a cost of production and transportation that depends on nature. If we don't take care of nature, we may end up in a situation where the cost of producing energy is more than we can afford. This winter, lets try to find ways to lower our energy consumption. One way to achieve this may be cranking down the heat and wearing a jacket to bed, or having an extra blanket. Not only will this help us lower our energy bills, it will strengthen us to face the changing energy world.
