Entrepreneur John Quinn is cashing in on the environmental trend with a green initiative designed to deliver savings to homeowners.
Established early last year, Greenloan's Home Energy Savers Scheme organises householders seeking green technology upgrades into groups to leverage economies of scale.

The idea is that, if several householders based in the same area want the same thing, they can benefit from lower prices from providers saving on labour and fuel costs.
An added advantage is that all of Greenloan's providers are certified to a high standard under the scheme.
The initiative launched in May, following a successful pilot scheme run last year in Dundalk, Tipperary, Clare, Limerick and Mayo.
Behind the initiative are a number of green technology companies, including Quinn's Surface Power, backed by semi-state agencies.
"There was an awful lot of support for foreign green technology products coming into Ireland. Irish companies were just getting lost in the mix," said Quinn.
"Ireland needs these innovative green technology companies to start growing and get out of Ireland.
"The scheme has made it a requirement that the companies enter an export-led programme with Enterprise Ireland. There is a whole initiative around exporting these companies' products into foreign markets.
Greenloan.ie runs a call centre where staff field enquiries from home and business owners looking to manage clusters in their area.
Michael Gillespie of Atlantic Energy Assessors is the building energy rating assessor for the Atlantic cluster in Westport, Co. Mayo. He has seen his company's business increase significantly as a result of its involvement in the scheme.
"It is making our own business and the business of other BER assessors stable for this year. We are getting great support from the administration team and help with advertising and guidance," said Gillespie.
Although not yet officially launched, Gillespie said the Atlantic cluster already had 30 households signed up.
"We have a target of about 200 in the coming weeks. We are getting huge interest in people wanting to join the cluster. The scheme is making the business absolutely viable," he said.
Quinn said the members of another group -- Greentech Industry Cluster -- planned to use the Greenloan model to launch collective export initiatives in emerging markets.
