The Department of Energy has created five green energy designs that it is proposing for people to carve into their Halloween pumpkins, including compact fluorescent light bulbs and windmills.
"To commemorate National Energy Action Month, we're featuring some scarily effective ways to save energy at home," the department said in a Monday blog post. "As cooler weather lurks around the corner, tune in to Energy.gov all week long for ways to save energy and money — and avoid cold weather terrors like energy vampires."
"We also put together some energy-themed pumpkin patterns to help 'energize' your neighborhood for Halloween," it said.
"Just print, cut out the dark parts on the patterns, trace onto your pumpkins, carve and enjoy!" the department added. "Better yet, use your imagination and design your own energy-themed pumpkin."
If the designs look familiar, they should — the Department of Energy trotted out the same five designs last year.
The department first proposes a CFL light bulb, complete with the familiar squiggly glass shape of the new bulbs that people will soon be required to use. A much easier windmill shape is also available.
The department has also made a recycling symbol out of leaves, a complicated design that will likely require a thin carving knife and lots of patience.
For highly advanced pumpkin carvers, the department suggests a complex sun and solar panel design — carving those little points on the sun will take some time, so plan ahead.
The symbol for an atom, representing clean nuclear energy, is also provided, a design that perhaps only experts should attempt.
The department doesn't say whether it's acceptable to use old-fashioned candles inside the pumpkins you carve, despite the smoke and heat some candles emit.
People who care "energy-themed jack-o-lanterns" are encouraged to send in pictures of their creations to the department via Twitter, Instagram, Facebook or email, and officials will publicize some that come in. People wanting to participate can send emails to email@example.com.
