Sustainable rooftop technologies - including green roofs, white roofs, and solar photovoltaic panels - can provide great environmental benefits, but studies of these technologies often look only at their use in hot climates and do not assess their full environmental consequences.
Researchers discovered a way to create hydrogen fuel using a biological method that greatly reduces the time and money it takes to produce the zero-emissions fuel; this method uses abundantly available corn stover.
In one of the first studies to examine the potential for using municipal wastewater as a feedstock for algae-based biofuels, scientists found they could grow high-value strains of oil-rich algae while simultaneously removing more than 90 percent of nitrates and more than 50 percent of phosphorous from wastewater.
Glass-fronted office buildings are some of the biggest energy consumers, and regulating their temperature is a big job. Now a facade element developed by Fraunhofer researchers and designers for glass fronts is to reduce energy consumption by harnessing solar thermal energy.
A new study offers a comprehensive reimagining of the power grid that involves the coordinated integration of small-scale distributed energy resources. The study asserts that the proliferation of renewable energy must happen at the periphery of the power grid, which will enable the local generation of power that can be coordinated with flexible demand.
In the first study of its kind, scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) quantitatively show that electric vehicles (EVs) will meet the daily travel needs of drivers longer than commonly assumed.
There is no single fuel solution for the future and therefore other alternatives based on the global combination of alternative fuels need to be explored. That is why BIOLCA has been developed. It is a tool that helps to specify, select and encourage more sustainable fuels.
Materials that change temperature in response to mechanical stress could make possible solid-state refrigerators that are not only more efficient than traditional vapor compression cooling technology, but environmentally-friendly replacements.
Poop could be a goldmine - literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now researchers are looking at identifying the metals that are getting flushed and how they can be recovered.
How do you take the sea of gases that makes up our atmosphere and convert that into liquid fuels? Or how do you remediate greenhouse gases and turn them into something usable for the chemical industry?
Construction crews may someday use a plant molecule called lignin in their asphalt and sealant mixtures to help roads and roofs hold up better under various weather conditions. It also could make them more environmentally friendly.
Adapting to climate change could have profound environmental repercussions, according to a new study. It reveals that adaptation measures have the potential to generate further pressures and threats for both local and global ecosystems.
Electric vehicles are cool, research shows. Literally. A new study adds more fuel to the already hot debate about whether electric vehicles are more environmentally friendly than conventional vehicles by uncovering two hidden benefits.
