Residential solar systems for electricity and heating water are most often installed separately, competing for limited roof space and the greatest amount of exposure to sunlight. Some newer hybrid models are overcoming this situation by combining photovoltaic (PV) and solar thermal technologies in an integrated system that uses the same surface area to capture (more…)

Each year, we come across a new set of discussions on the subject of Moore’s Law – the idea that the potency of technology doubles every two years. Intel co-founder Gordon Moore observed that the number of transistors that could be put onto an integrated circuit doubled with that regularity — and that this exponential growth persisted for an astonishingly long period of (more…)
An activist caravan to bring one of Jimmy Carter’s solar panels back to the White House symbolizes not only the time the U.S. has lost in developing new energy technologies – but also the urgent need for taking action on climate.
