Equine Environmental Law: Manure is Power

Some environmental groups oppose the presence of horses (and cows) on the basis of water or soil contamination.
Composting and recycling our horse manure has been the best thing to ever happen to our gardens (we feed our horses well, so the fertilizer is high quality!), but initiatives like the following are certainly intriguing, and give an additional meaning to "green" energy:

An all too familiar sight! 
"In February the Norco City Council in Riverside County voted 5 to 0 to move forward with a proposed $36 million manure-to-power conversion plant. Chevron believes the plant would be the first of its kind. The city often referred to as “Horsetown USA” looking to be a leader in the green energy movement, took their manure challenges to Chevron Energy Solutions. The city will order an environmental impact report on the plant. Chevron Energy Solutions presented an engineering study that showed the plant would be viable. The plant would take 18 months to two years to build on unincorporated land a few miles outside of town. The proposed plant would dispose of an estimated 65 tons of horse manure produced daily by the city's 17,000 horses. The plant would end the $17.25 per ton cost of disposal as well as generate annual power revenue of about $7 million for the small city. One of the issues still to be resolved is the lack of long term leases on the drying fields." 
What does your farm or ranch do with the horse manure: compost/ garden, donate, pay a disposal fee, or convert to energy, other?
