Fossil fuels are a contributor to climate change, and they are nonrenewable resources. Thus, the scientific and agricultural communities have been interested in identifying alternative, sustainable energy sources for quite some time. Hydrogen, solar, wind, and nuclear energy are already being utilized around the world. Biofuels have also shown amazing promise, with scientists even developing a genetically modified version of algae that could potentially undo damage by removing carbon from the atmosphere.
For now, modern agriculture is focused on finding ways to use less energy whenever possible on the farm. Using digital tools and techniques like conservation tillage, farmers make fewer passes through the field with machinery and reduce their carbon footprints.
