Every day at the Energy Department, we work to make America more competitive in the global clean energy race and help communities save energy and money.

Are you planning any scary ways to save energy this Halloween?

Every year I try to convince myself that I am going to turn my thermostat down for the entire winter. It's going to be 68 degrees or lower, I tell myself. I'm not going to turn it up for any reason. I might even be daring and try to get a few degrees lower! It'll be awesome!

It usually doesn't end well. You see, I'm a gigantic wuss about the cold. Something always happens—it takes me 4 hours to drive home in the snow, I have a lousy day, or it drops beneath zero degrees Fahrenheit—and suddenly I want to treat myself to a balmy 70 degrees to make up for it.

With the fateful transition to cooler weather and Halloween just upon us, it is important to remember some key tips when preparing to have the most energy-efficient Halloween possible.

Whether you're using renewables or energy efficiency (or both), what are you doing to prepare your home for cooler weather?

How can you save energy (and money!) as we head into cooler months? Here's some tips.

ItWe often associate renewable energy as future, forward-thinking technology. However, just as in the case of da Vinci’s curved mirror – many of these technologies are based on centuries old concepts and inventions.

A reminder of all the resources the department provides to help us learn about subjects such as cool roofs, energy-efficient lighting choices, geothermal heat pumps, and many more.
