KIEV, April 26 – Ukraine currently cannot stop using nuclear energy, but it must think of alternative energy, President Petro Poroshenko said.

"It is clear than neither today nor tomorrow Ukraine would not be able to stop using nuclear energy, diversifying supplies of energy and striving for energy independence. We must think about new solutions, new alternative and conventional energy, energy efficiency," Poroshenko said during his visit to Chernobyl on Tuesday.
