Researchers at the Massachusetts Institute of Technology (MIT) say they have achieved a major breakthrough in the conversion of sunlight into electricity, surpassing what was long believed to be an absolute limit to the efficiency of solar cell devices. (more…)

I’ve added a hot new business plan to the list I’m now featuring. I spoke yesterday with Joe Speace, CEO of “Project Renewable Energy” near Kansas City, whose raising capital for a wind farm that will feature compressed air energy storage (CAES). This looks quite strong.

Storage will be a big deal soon, as the (more…)

According to a recent study, humans are not the only animals to take part in a solar economy of sorts.  While it may not attend solar training courses or pursue green careers, the Oriental hornet harvests the power of the sun for energy.

The recent findings were discovered by Israeli and UK researchers and published in the German journal, Naturwissenschaften. (more…)

The goal is to enable power generation from low-temperature geothermal resources at an economical cost. In addition to being a clean energy source without any greenhouse gas emissions, geothermal is also a steady and dependable source of power.

A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) are testing a new innovative approach to safely and economically extract and convert heat from vast untapped geothermal resources.
