International Energy Agency Executive Director Nobuo Tanaka in a statement said Poland has made "impressive efforts" to develop a sound energy policy.
The IEA report notes Poland has enhanced energy security by expanding its underground gas storage capacity, building a terminal for liquefied natural gas and expanding domestic and unconventional gas production.
"All these efforts should be continued and enhanced to meet the expected growth in gas demand," said Tanaka.
The report praised Warsaw for adding diversity to its energy mix but also said the level of greenhouse gas emissions were higher in Poland than in most other European countries.
Poland, the IEA said, has a "unique opportunity" to make important gains in energy diversity and security.
"Like other countries, Poland must raise climate change to the top of the national policy agenda and take crucial decisions in order to stabilize greenhouse gas emissions," the report adds.
