The National Farmers Union of Scotland is urging the UK government to think again over a cut in support for some types of renewable energy.
Anaerobic Digesters are ideal for farmers, because they convert waste products into energy.
There's been a reduction in the tariff payed to people who produce energy in this way and the NFU Scotland fears that could discourage farmers from installing so-called AD plants.
Fiona McIlwraith went to a farm in Dumfries and Galloway which is building one of the first plants in Scotland.
The National Farmers Union of Scotland is urging Westminster to restore support to a new type of renewable energy.
Anaerobic Digesters use waste product to produce electricity, however the Government have reduced the tariff scheme and NFU Scotland says farms will suffer unless the original tariff is reinstated.
