This opinion piece explains how switching to renewable energy sources like solar and wind can reduce the environmental impact of farming. It highlights the role of green ammonia in producing nitrogen-based fertilizers without fossil fuels, cutting greenhouse gas emissions from agriculture. The author argues that renewable energy is cheaper than fossil fuels in many regions and can create more jobs, while also making food systems more resilient to economic disruptions. The article points to early green ammonia plants being built in Chile, Morocco, and Australia as examples of this shift. However, it notes that the transition requires sustained government investment and commitment. The piece also cautions that biofuels from crops like corn and rapeseed can compete with food production and land use for carbon storage, so not all renewables are equally sustainable. For readers interested in climate-smart agriculture and decarbonizing industrial processes, this article provides a straightforward overview of how renewable energy can replace fossil fuels in farming. It connects fertilizer production, energy policy, and food security in a single narrative.
