The competition, which was officially launched by teacher and former Rose of Tralee winner Aoibhinn Ni Shuilleabhain, is open to all primary schools students.
Tell The Future encourages children to write a short story on how to power our homes, hospitals, factories and schools into the future.
"Growing up, most of us will have imagined what it would be like to be in charge of everything -- to make all the big decisions," says Aoibhinn.
"The Tell The Future competition has a strong environmental focus and gives primary school children a chance to express their ideas about how they see the future," she adds.
The competition is part of the Future Of Rural Energy In Europe (FREE) initiative, supported by Calor Gas.
Prizes for the winning students and their schools include interactive white boards, laptops, Kindle e-book readers, and concert/pantomime tickets.
