Prickly Pear cactus is drought-resistant, can be grown where other crops die, and makes surprisingly good fuel for anerobic digestion, which then creates biogas. The cactus breaks down much faster than manure and is considered a nuisance in many areas now. It can be harvested, perhaps on commercial scale, to produce natural gas or generate electricity.

Toronto introduces biogas garbage trucks which run on CNG or biogas. They hope to make enough biogas from the garbage to run their entire fleet of 300 garbage trucks.
I find technology like this postively inspirational because it takes a problem (what to do with the garbage) and turns it into a solution.
Why is it that Texas so totally gets it on energy while other states lurch around? Texas is the US leader in wind energy, has a completely self-contained power grid, is installing the first offshore wind power in the country, and now San Antonio is turning sewage into an income stream.
Poop from a dairy farm will be converted to biogas and will provide heat for up to 1,100 homes. Not only is this recycling at its best, it also saves diary farms time, money, and hassles because they don’t have to maintain gigantic manure ponds.
Loblaw’s will now send scraps from their 47 stores to StormFisher biogas plants to be converted into energy. Not only does this cut down on carbon emissions, it creates a new revenue stream from something that previously had to be sent to a landfill.
