Modern day agriculture and farming is highly energy-intensive but farms also offer a variety options for alternative sources of energy. Biogas from farm waste is a viable source of energy in dairy farms that can not only supply energy for the farm’s operations but also solid fiber to be used as cattle bedding and a nutrition-packed natural fertilizer for organic cultivation. Irrigation systems fitted to take advantage of the gravity inherent in the landscape to facilitate the flow of water save valuable power. Variable speed drives on vacuum pumps, CFL bulbs for lighting, opportunities for wind and solar power generators – there endless possibilities to make farming more green and clean.
