Business organisation Ibec has said the party leaders involved in Government formation talks must commit to a comprehensive review of Ireland's energy security needs.
Danny McCoy said this must take place as Ireland moves away from the use of fossil fuels.
"The move to a low carbon economy is not optional," he said.
"It is critical to our future wellbeing and long term competitiveness. But the transition must also be practical and evidence-based."
A recent survey by the business representative group found four-fifths of members expressed concern about the possibility of a pre-emptive decision to rule out future investment in specific energy technologies such as natural gas, in advance of understanding the implications for energy supply security.
In the first two weeks of May alone, natural gas met four fifths of Ireland’s power need, Ibec said.
"Specifically, as a society we need to better understand the role of natural gas in the transition," Mr McCoy said.
"It remains the only option for many of our largest industries and nobody has yet presented a viable future energy scenario for Ireland without natural gas."
The business leader urged the parties to examine the issue closely and base policy on only evidence.
The intervention comes as the talks on the formation of a new Government involving Fine Gael, Fianna Fáil and the Green Party continue to inch slowly forward.
