Energy efficiency programs aimed at reducing energy waste cost utilities only about three cents per kilowatt hour, while generating the same amount of electricity from sources such as fossil fuels can cost two to three times more.
Panasonic Corporation today announced that it has achieved a conversion efficiency of 25.6% in its HIT solar cells, a major increase over the previous world record for crystalline silicon-based solar cells.
To fly once around the world, across continents and oceans - powered by the Sun; this is the unprecedented goal of the SolarImpulse project. The flying venture is expected to take place in 2015, using an extremely lightweight aircraft covered with solar cells and powered by four electrically driven propellers.
Future generations will have to pay more for today's carbon emissions than what governments across the world currently understand. The climate models used by policymakers around the world to estimate the economic and social costs of CO2 emissions have to be improved.
Creating environment friendly energy storage systems, non-explosive and with charge/discharge long-term cycles, motivated a group of scientists to research which polymeric materials have the properties to maintain the highest level of energy in a lithium - ion battery.
The iC4 project aims to optimize the conversion of carbon dioxide into synthetic natural gas - a process that has been known for over 100 years - to make the process economically viable. First successes have now been made.
What began 20 years ago as an innovation to improve paper industry processes and dairy forage digestibility may now open the door to a much more energy- and cost-efficient way to convert biomass into fuel.
Researchers have developed a new way to study wake effects that includes the airflow both within and around a wind farm and challenges the conventional belief that turbines arrayed in checker board patterns produce the highest power output.
Pumped storage power plants are firmly established in the German power grid: surplus electricity can be stored for a moment and then quickly supplied during a demand peak. The BINE Projektinfo brochure 'Storing wind energy underground' presents a concept of how to reuse abandoned ore mines as pumped storage power plants.
