To celebrate Earth Day, sign up for Online Services and turn off your paper bill between April 1st and May 9th and we'll have the Arbor Day Foundation plant a tree in your honor. Plus, you'll be automatically entered to win one of five grand prizes of a $150 credit on your National Fuel bill.

------------------------------------

Handling bills by mail wastes your time and the planet's resources. Once enrolled in National Fuel's Online Services program, you could help put an end to that.

With Online Services you can:

• Stop getting paper bills - sign up to receive electronic notification instead.

• Stop writing checks - enroll in the Direct Pay program and your payment is deducted automatically each month.

• Save on stamps - sign up to submit meter readings online.

• Budget easily - enroll in the Budget Plan, and stabilize your monthly bill for up to one year.

Keep our planet healthy. The energy consumed by making and delivering paper bills puts carbon emissions in our atmosphere, which accumulate even faster when trees that clean the air are cut down to make paper. When you go paperless, you can help stop this destructive cycle.
