Across the world, farmers and machinery producers are stepping up to the challenge of reducing greenhouse gas emissions by electrifying essential equipment and exploring alternative fuels ... In New Zeland's Otago, cherry producer Mike Casey has been running a 6-hectare orchard without using any fossil fuels. Last year, it produced 80 tonnes of cherries for local and export markets. His fleet of 21 electric machines includes prototypes and traditional vehicles that have been converted to electric. "I never envisioned us going fully electric; I was just sort of thinking there will be some things that we can do to cut out diesel and cut our emissions," he said. "But what actually happened is we discovered we'd save about $40,000 a year of energy costs on our farm."
