"Black smoke from Speight's Brewery could clear if Lion joins a growing move away from coal-fired boilers in Dunedin. The Energy Efficiency and Conservation Authority has been pushing clean-burning wood energy in Dunedin since 2008, and had so far worked with nine of the city's sizeable organisations - including the University of Otago - making the switch"

"The Government wanted an additional 9.5 petajoules of energy to come from clean-burning wood energy by 2025, which was an increase of roughly 10 times the energy consumed by Nelson each year, he said. The cost of a new wood-fired boiler ranged from less than $100,000 to more than $1 million, depending on the boiler's output, making it twice the cost of a gas-powered model. However, once operating, fuel costs for wood-fired boilers were "half to one-third" those of gas, making them a cheaper option in the long term, he said"
