She said: “It is encouraging to see NI water take positive steps to decrease their carbon footprint and promote renewable energy.
“The use of solar energy is even more encouraging as more needs to be done to diversify our renewable energy portfolio in the North.
“The cost of renewable energy has dropped dramatically in the last few years, this together with the benefits of renewable energy will hopefully encourage NI water to look at installing Solar Farms in some of their other facilities.
“I would encourage more companies to invest in renewable energy, especially on the back of the Bonn climate change conference held in Germany last week.
“It threw into stark reality that we need more action and more ambition to tackle climate change,” she added.
