You can use an energy-saving bulb to save energy. Obviously an energy-saving bulb uses energy, but it uses less than the old sort - about 80% less. In saving energy you will have lower bills to pay for the energy you use, and the environment also benefits because less CO2 is released into the atmosphere at your nearest power plant.
