Contrary to what Kermit the Frog once said, it IS easy being green, mainly because there is no accepted definition of the term. To cite but one example, how was it ever decreed that reusable shopping bags are green?
Even though some of them are made from recycled materials (although the percentage is not easily determined), all of them are derived from petroleum, and are manufactured in what overall cannot be a benign or low-energy process. Then, millions of them are shipped over here from China, at a cost of still more energy and carbon emissions.
They don't last forever, of course, and are then discarded—mostly to landfills, while conventional grocery bags are easily recycled.
Yet, because they are visible and are used by self-affirmed trendsetters, they have become a symbol for environmental stewardship.
Traditional broadband requires laying fiber or cable and the attendant energy and pollution costs. Broadband over power line (BPL), however, allows already in-place power lines to be the conduit, and this is green by anyone's reasoning.
One innovative company in this space is Gridline Communications, coming off successful projects in Africa, Latin America, Texas, Arizona, and New Mexico. CEO Terry Dillon speaks of his company's new intellectual property that will have "disruptive impact" (in a good way) on BPL.
