Economic trade-offs of owning versus leasing a solar photovoltaic systemTue, 27 Jan 2015 11:10:29 EST
Two new reports examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. Analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner. Carbon nanoballs can greatly contribute to sustainable energy supplyTue, 27 Jan 2015 10:01:53 EST
Researchers have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system. The renewable energy sources of tomorrow will often be found far away from the end user. Wind turbines, for example, are most effective when placed out at sea. Solar energy will have the greatest impact on the European energy system if focus is on transport of solar power from North Africa and Southern Europe to Northern Europe. Calculating the future of solar-fuel refineriesFri, 23 Jan 2015 11:07:54 EST
A team of engineers has developed a new tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries. New technique helps probe performance of organic solar cell materialsFri, 23 Jan 2015 11:07:52 EST
Researchers have developed a technique for determining the role that a material's structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The researchers used the technique to determine that materials with a highly organized structure at the nanoscale are not more efficient at creating free electrons than poorly organized structures -- a finding which will guide future research and development efforts. New technique for producing cheaper solar energy suggested by researchFri, 23 Jan 2015 11:07:50 EST
Pioneering new research could pave the way for solar energy to be converted into household electricity more cheaply than ever before. The global PV market has experienced rapid growth in recent years due to renewable energy targets and CO2 emission controls.
