Plans are due to be announced soon for the clean energy cash bank scheme, which would pay households premium rates for any green energy they produce.
Friends of the Earth's executive director Andy Atkins said that "bigger government incentives are needed".
He said: "Ministers must listen and introduce an ambitious feed-in tariff scheme that will encourage millions of households, companies and communities across the UK to join the green energy revolution."
Results from the survey also showed that 71 per cent of households would think about installing microgeneration technology if the benefits were high enough.
However, Doug King, who recently wrote a report on carbon emissions for the Royal Academy of Engineering, said that eco-bling items, such as miniature wind turbines, would do little to cut greenhouse gases.
