A County Antrim hospital has come up with a way to cut down on its electricity bill - by generating its own power.
A wind turbine has saved Antrim Area Hospital £90,000
The 40ft wind turbine used to generate the power at Antrim Area Hospital is off the health facility's campus.
The turbine has already generated more than 250,000 units of electricity, and is on course to save £90,000 a year - a quarter of the hospital's power bill.
It cost £0.5m but hospital bosses got all but £100,000 of that in a grant.
From next year the money that would have been spent on power will be freed up for improved services for patients.
Antrim is the first hospital in Northern Ireland to get a turbine, but now other hospitals across the province are taking an interest in what it has been doing.
