Getting clean water to communities in parched areas of the planet remains an ongoing challenge. Recent developments that harvest water from air have been proposed as a solution. Based on new modeling results, scientists report that a new system design would require less energy and produce high-quality water.
Researchers have developed a panel with textile waste that improves both the thermal and acoustic conditions of buildings and reduces the energy impact associated to the production of construction materials and greenhouse gases emissions.
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.
