The United Kingdom needs to increase its investment in renewable energy, the Taoiseach has said.
The call came as Enda Kenny met his British, Northern Irish, Scottish and Welsh counterparts face-to-face during key talks.
The British-Irish Council gathered in Cardiff Castle for its once-a-year meeting. Key items on the agenda were kick-starting the economy and Europe, as well as education.
During a press conference, Mr Kenny said energy and the environment would be the big topics that would need to be discussed in depth next time the home nations' political leaders got around the table.
He said: "The issue of energy will be a direct focus of the next British Irish Council.
"We believe there is great potential for renewable energy, particularly from onshore wind.
"There is a real possibility for the direct sale of renewable energy generated in Ireland to a British market.
"This is against a background of where we need to move on at European level.
"The Union is losing out in terms of real investment- where major energy costs are 300% dearer than they are in the United States, which is moving to self-sufficiency with enormous potential from the sale of shale gas.
"Between our two islands having these strategic partnerships, this is an area that has great potential."
