Set your water heater at 120 degrees to save energy. If it is more than 5 years, wrap it in an insulating blanket. Buy low-flow showerheads that save hot water and about 350 pounds of carbon dioxide per year. Wash clothes with warm or cold water to reduce the energy required for hot water use and production. In most households, this change alone saves at least 500 pounds of carbon dioxide per year. Use the energy-saving settings on the dishwasher to allow the dishes to air dry. By turning off the lights when leaving the room, you save power and reduce global warming, and use only as much light as possible. And remember to turn off the TV, video player, stereo and computer when not in use. It is also a good idea to turn off the water when you are not using it. When brushing your teeth, washing your dog or washing your car, turn off the water until you really need to rinse it. You will reduce your water bill and help save important resources. If you have a way to plant trees, start digging. During photosynthesis, trees and other plants absorb carbon dioxide and release oxygen. They are an integral part of the natural atmospheric exchange cycle on Earth, but they are too few to completely offset the increase in carbon dioxide caused by car traffic, manufacturing and other human activities. Helping to mitigate climate change: A tree will absorb about a ton of carbon dioxide during its life cycle. Many utility companies offer free home energy audits to help consumers identify areas of the home that may not be energy efficient. In addition, many utility companies offer discount programs to help pay for the cost of energy-efficient upgrades. Share information about recycling and energy conservation with your friends, neighbors, and colleagues, and seize opportunities to encourage public officials to develop environmentally friendly plans and policies. These steps will help you reduce your energy consumption and your monthly budget. Reducing energy consumption means reducing dependence on fossil fuels that produce greenhouse gases and cause global warming.
