We have found the best way to control efficiency is by fine-tuning the boilers. Our custodians make sure they check the rooms when they clean and close the blinds to keep out the cold air and then open them when the sun comes up.

Our newer schools have thermostats in classrooms that teachers can control, but they don't go lower than 68 or higher than 70.

We are not doing anything different than what we typically have done.

We want customers to see energy efficiency as the best way to take control over their energy costs. It's an important response to the higher cost of natural gas, which has increased nationwide.

In this era of globalization, corporate responsibility is no longer merely about local labor issues, pollution control, or energy efficiency. Sustainable businesses are those that are helping find global solutions to our most pressing environmental and social issues.

For the skeptic there remains only one consolation: if there should be such a thing as superhuman law it is administered with subhuman inefficiency.
