Can energy efficient lighting make a real difference for the environment?

• Combined number of commercial buildings (4.8 million) and industrial facilities (350,000) in the United States: over five million • Combined annual energy costs for U.S. commercial buildings ($107.9 billion) and industrial facilities ($94.4 billion): $202.3 billion; Portion of energy in buildings used inefficiently or unnecessarily: 30% • Combined percentage of U.S. greenhouse gas emissions generated by commercial buildings (17%) and industrial facilities (28%): 45% • Percentage of energy use reduction targeted by the ENERGY STAR Challenge: 10% • Amount of money that would be saved if the energy efficiency of commercial and industrial buildings improved by 10%: $20 billion • Amount of greenhouse gas emissions that would be reduced if the energy efficiency of commercial and industrial buildings improved by 10%: equal to approximately 30 million vehicles.  more
