We could generate a lot of usable energy from human and animal poop through greater adoption of a process for using microbes to break down poop into methane gas.

To learn more, start your googling with these keywords:

Anaerobic digestion: a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen

Methanogens: a methane-producing bacterium, especially an archaean which reduces carbon dioxide to methane

Wastewater treatment: a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused

Biogas: the mixture of gases produced by anaerobic digestion of organic matter, primarily consisting of methane and carbon dioxide, which can be used as a renewable energy source
