Green Options

Up to 50 percent of all fuel burned in the US goes unused into our atmosphere as wasted heat; the US Department of Energy has found. The total, a mind boggling 7 quadrillion BTUs; exceeds the current output of all other US renewable sources - such as solar, wind and geothermal, combined.

We could use this potential waste heat capacity to generate 46 GWs of new, clean electricity annually.

Lolland-Falster, Denmark
Until recently, I might have searched California’s sustainable communities to find the greenest living place on the planet.  To my surprise, on a recent visit to
Lolland-Falster (LF), two Danish islands with about 120,000 residents
combined, I was introduced to a place that takes sustainability to the next level and provides a glimpse into the future.
