The Margaret Chase Smith Library has announced that the theme of its 11th annual essay contest centers on a national energy policy.

Because of geopolitical turmoil and natural disasters, Americans have seen oil and gas prices soar over the past year. The continued economic expansion of emerging countries such as China and India means demand for energy is increasing at a time when many experts forecast the supply has peaked. Added to the equation are concerns that burning fossil fuels contributes to global warning. With these factors in mind, the library invites Maine high school seniors to submit essays proposing a comprehensive national energy policy.

The library will award the following prizes to the top entries: $500 for first place, $250 for second place, $125 for third place, as well as five $25 honorable mention prizes.

Essays are due by April 2, 2007. Prizes will be announced on May 1.

To submit entries or for more information about the contest, contact David Richards at the Margaret Chase Smith Library, 56 Norridgewock Ave., Skowhegan, ME, 04976, or call 474-7133.
