The sun doesn't always shine and the wind doesn't always blow, but a state lawmaker is promoting a renewable energy source that's available in any weather: biogas.
So what is biogas? You might not want to know.
Put delicately, it comes from animal manure and the human equivalent.
"It is about as renewable as it gets," said Rep. Rick Murphy, R-Glendale.
Murphy has authored HB 2373, which would provide tax incentives for firms that build facilities to generate biogas. The measure has won committee approval and was awaiting action by the full House.
Murphy wants biogas, a process turning human and animal waste into methane, to be among the options utilities can use to achieve the Arizona Corporation Commission's mandate of generating 15 percent of their energy from renewable sources by 2025.
