Many communities throughout Scotland will be able to tackle prices from energy suppliers using their share of £3.6 million worth of efficiency funding from the Climate Challenge Fund.
The UK's biggest community-owned wind farm and household carbon audits will be among the 41 projects receiving funding, which adds to around £16 million that has already been allocated to almost 200 Scottish projects.
Richard Lochhead announced the additional funding at Edinburgh University, where efforts are under way to reduce the carbon footprints of students and staff as they travel to and from the campus.
Mr Lochhead said: "The Climate Challenge Fund is helping to generate grassroots action across Scotland and once again we have received a huge number of applications."
He added that he was impressed at the innovation evident in many of the projects that applied for funding from the scheme.
Installing measures such as cavity wall and loft insulation can help reduce both carbon emissions and energy prices.
