In Portugal the world's first hydro-solar power plant has commenced operation. The Alto Rabago dam, near the country's northern border with Spain, added 840 floating solar panels earlier this year, Floating solar panels offer a means of expanding hydroelectric plant's energy capacity without embarking on costly dam reconstruction.
According to MIT researchers 3D solar towers can generate anywhere from double up to 20 times the amount of energy as flat solar panels with the same base area. These 3D designs increase electricity output because their vertical surfaces allow them to capture sunlight even when the sun is closest to the horizon during mornings, evenings and winter and when sunlight is partially obstructed by shadows or cloud cover.
Canadian Solar, one of the world's largest solar power companies, has acquired a minority equity interest in eNow, a U.S. company specializing in solar-based energy management system for the commercial transportation industry. The investment will accelerate the expansion and growth of photovoltaic (PV) based mobile energy solutions which will reduce transportation fuel costs while making a significant impact in cutting vehicle emissions in the commercial transportation industry.
