Add Energy Renewable Romania Although conversion efficiency has become the leading measure by which solar cells are judged, this is not necessarily the best yardstick. In fact, slavish adherence to it can be counter-productive. As Jim Nelson, ceo of U.S. company Solar3D Inc points out, solar efficiency is generally measured under optimum conditions with direct sunlight … Read more
Mainstream Solar PV research remains focused on the development of more efficient multi-junction PV cells – and with 50% efficiencies in sight, it is easy to see why. But efficiency at this level comes at high cost. Concentration is potentially something that could be added to products to change the solar cost metrics. … Read more

How much renewable energy will the world consume in the coming decades? That depends on who you ask. If you’re an oil company with a stake in the continued use of fossil fuels, you’ll probably downplay the penetration of renewables. If you’re an international organization with a conservative reputation, you’ll probably see … Read more
Where are the three most promising wind energy markets outside Europe – and why? The first country with promising opportunities is Brazil – a dynamic high growth country which is starting to embrace renewables. And with the World Cup and Olympics coming up, the world’s attention will be focused on Brazil. Then … Read more
Low margins for photovoltaic manufacturers have a history: until 2004 most PV manufacturers had low to no margins on cell and module sales. The price function has historically been controlled by demand participants (system integrators, installers et al) and this group was not price elastic – nor, as their own demand function was a … Read more
Aquamarine Power's subsidiary, Lewis Wave Power, will install 40-50 "Oyster" devices, but it has to wait for the undersea cable to be in place which won't happen until 2017, says transmission firm SSE. ABB holds an equity share in Aquamarine, one of its many cleantech investments. Oyster is essentially a wave-powered pump that pushes high pressure water … Read more

Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While “artificial leaf” is the popular term for such a system, the key to this success was an “artificial forest.” Schematic shows TiO2 nanowires (blue) grown on the upper … Read more
Solar panels have come along way in recent years. Just ask renewable energy expert Kevin Moore, president of Midwest Wind and Solar. “The concept of solar power has been around for many years,” he said. “But until recently, its reach in the US has been limited to mainly those leading the environmental movement. … Read more
Without doubt, the most affected sector will be wind power that had the most investments and has reached 2200 MW of installed power. In fact, after analysis, we find that wind power generated and generates electricity price decreases and this is openly acknowledged by all those that buy now cheaper energy, due to … Read more
