Enterprise Minister Arlene Foster defended her department's record on green energy promotion, saying that DETI had engaged a cross-departmental approach, on 5 October 2010.
During the resumption of the debate, Alban Maginness, chair of the enterprise committee, said that the issue of green energy was relatively confined to DETI, and that there was no collective acceptance of responsibility across the Executive.
Moving the Alliance motion on a Green New Deal Sean Neeson called on the Executive to implement a cross-departmental strategy.
He said that there had been a failure to allocate responsibility for current targets in the Programme for Government.
For the DUP, Simon Hamilton said that Northern Ireland could be the "Saudi Arabia of alternative energy", but that had to be a created reality. He said that Northern Ireland's underlying manufacturing base could maximise the potential for tidal energy.
Samuel Gardiner said that the green energy job creation should be used to offset rising youth unemployment.
Sinn Féin's Cathal Boylan called on the Executive to make easier for individuals to build small wind farms.
He concurred with the DUP's Ian McCrea that elected representatives should support wind farm planning applications.
Speaking to the SDLP's amendment Conall McDevitt said that there was potential for the creation of 30,000 jobs in a "green economy" and called on the government to create jobs for tradesmen in refurbishing houses.
The Green Party's party's Brian Wilson said that more ambitious targets were needed to encourage Northern Ireland to become a world leader in renewable energy production.
