  3. PIG-POWERED Eco Lodge in Costa Rica from Inhabitat

    While you may not naturally associate pig feces with ‘clean’ energy, the Lapa Rios Ecolodge in Costa Rica manages to makes pig poo power seem smart, sexy and super sustainable with their environmentally friendly resort. …But less you think this sounds like some tie-dyed hippie commune – take a look at the photos. The lodge is as beautiful and relaxing as any five star hotel, and probably a lot more enjoyable to anyone with a sense of adventure or imagination.

  9. Geothermal: flourishing under the shadow of solar from Clean Break

    Solar technologies get way too much attention when, in reality, the benefits today of geothermal energy and putting “geoexchange” systems in homes and businesses are much more compelling. The payback is shorter, and avoidance of greenhouse gas emissions is greater. That said, I kind of know the reason why geothermal gets less respect. For one, investors love patent-protected technologies, and the different approaches to making solar cells and the variety of materials used creates a lot of opportunity in a booming market. Geothermal system are more expensive upfront, and the installation itself is labour-intensive and complex. Most of the cost, in fact, comes with drilling and laying tubes in the ground. The heat pump systems at their core are simple devices — easy to mass-produce but little in terms of intellectual property worth protecting.

  10. New Power Supplies Could Save $3 Billion / Yr from EcoGeek

    You might think your desktop computer is efficient; after all, they use about as much electricity as one old-fashioned lightbulb…seems like a pretty good use of electricity to me. The bad news is that up to 50% of the power your computer uses is immediately lost as heat by your power supply. Frankly, that is a waste, and one that adds up to billions of wasted kilowatts (and dollars) per year.
