Anaerobic digestion – extracting methane from organic wastes – doesn’t get the love of, say, solar and wind: it’s not nearly as sexy, and definitely more smelly. But it’s also a renewable energy technology with plenty of available feedstock: all of that food waste we discuss regularly could go towards the creation of biogas.

As the cost of solar panels continues to decline and the technology continues to improve, both in collection and storage capacity, the use of solar could become an even more attractive option.
Living off the grid sounds romantic…no more bills from dirty energy companies, self-sufficiency, green power, etc.; however, there is one “dirty little secret” found in most alternative energy homes. Without it, some off-gridders couldn’t cook, refrigerate, heat water, or dry clothes. That dirty little secret is propane. Propane is a “by-product of natural gas processing and petroleum refining,”.

Beyond the immediate need to minimize further radioactive leakage and protect public health, the government is beginning to reconsider its long-term plans for nuclear power […]
So we’ve all heard lots about the benefits of solar energy, but there’s another energy source you may have never considered harvesting: body heat. Yes, that’s right—your body could be expending usable energy right now as we speak. The “hybrid energy harvesting device” created by Fujitsu Laboratories would work with solar energy to complete a […]
I just generated 20 minutes of green power. It took me less than five minutes. How did I do it? I added the Facebook application Green My Vino to my Facebook account and then sent one green power minute to 20 of my Facebook friends. Green My Vino was launched earlier today by Village Green […]
Regular readers of sustainablog know that I’ve become a big fan of St. Louis-based Solar Night Industries since company president and founder Jason Loyet first reached out to me in early 2006. Jason and team have been kind enough keep me in the loop about new developments, and I’ve been impressed with what I’ve seen […]
