The Energy Department's National Renewable Energy Laboratory (NREL) has released the 2016 Annual Technology Baseline. In addition to updated data for utility-scale renewable and conventional energy technologies, this year's version includes cost and performance data for residential and commercial rooftop photovoltaics systems.
The window of opportunity for limiting climate warming up to 2 C is closing rapidly. However, a reinforcing upward spiral of national government policy, non-state actions and transformative coalitions will be essential even after the Paris agreement, if dangerous climate change is to be avoided.
The Spanish technology centre Cener gives an overview of the first results coming from the testing phase on the software, the blade configurations and the control strategies developed during the European Windtrust project.
Advanced detection of wind anomalies could help prolong the lifespan of wind turbine components and reduce the cost of wind energy generation. In this context, European researchers have developed smart control software.
A European research project has launched a set of tools that will make computer systems more energy efficient - a critical issue for modern computing. Using the framework of the project programmers has been able to provide large data streaming aggregations 54 times more energy efficient than with standard implementations.
By way of a light-driven bacterium, biochemists are a step closer to cleanly converting harmful carbon dioxide emissions from fossil fuel combustion into usable fuels. Using the phototropic bacterium Rhodopseudomonas palustris as a biocatalyst, the scientists generated methane from carbon dioxide in one enzymatic step.
Researchers have combined components that have already proven effective in industry in order to develop a robust and effective system. Their prototype is made up of three interconnected, new-generation, crystalline silicon solar cells attached to an electrolysis system that does not rely on rare metals.
Plastic food packaging not only creates a lot of non-recyclable, non-biodegradable waste, but thin plastic films are not great at preventing spoilage. And some plastics are suspected of leaching potentially harmful compounds into food. To address these issues, scientists are now developing a packaging film made of milk proteins - and it is even edible.
