Liberal Democrat MSP Liam McArthur told the chamber the UK government's committment to deliver £250 million of additional funding for Scotland through the green investment bank should be welcomed by Holyrood.
Mr McArthur said the funding from the Fossil Fuel Levy surplus would support renewables in Scotland.
Climate Change Minister Stewart Stevenson said the announcement of this funding was a "distant offfer" with a three year period where the Scottish government would be denied access to the money.
The UK government's committment was a "chimera, a conjuring trick and a con", added the minister.
Green MSP Patrick Harvie said the funding available to the proposed green investment bank had been cut from £2bn to £1bn which would be a "drop in the ocean" compared to the cash put into "dirtier energy sources".
