Business owners struggling in the recession were today urged to cut costs by switching to renewable energies.
Going green can slash bills by up to 15%, according to wind farm energy company Energia.
The Belfast based firm, which already supplies electricity to 40,000 businesses across Ireland, has launched a new campaign to highlight the benefits of renewables.
"We are opening up the Northern Ireland renewable energy market to small businesses and have already signed up hundreds of customers," said Energia spokesman Michael Nugent.
"These range from manufacturers to PR companies and printing works to restaurants and each time we have been able to reduce their energy costs sometimes by up to 15%."
"For many small firms, cutting costs is a matter of survival and urgency and Energia is playing a central role in supporting businesses efforts to reduce overheads. The process is also simple as there are no new wires or meters required."
One firm that has signed up is Londonderry promotions and printing firm Partridge Peartree.
"This is not only a good deal for us but by switching to Energia's renewable energy tariff we are massively reducing our carbon footprint," said Partridge Peartree business development manager Claire Higgins.
"Renewable energy was previously the preserve of the wealthy because of its high cost, but now we can implement our renewable policies which make us more commercially competitive as our clients seek out ethically sound suppliers."
