Home-scale anaerobic digesters produce more energy than solar panels anytime day or night, rain or shine while generating high-quality fertilizer for local food security and diverting organic waste from landfills. Biogas is the same as fossil natural gas only instead of taking 65 million years to make, we can make it every day in our own backyards, enjoying energy independence and security while improving the environment. The carbon in biogas is biogenic carbon and not considered an excessive greenhouse gas---we exhale biogenic carbon every few seconds. There are 50 million households in China using biogas, it's time for the US to catch up!
