Until now, it has taken weeks to make biofuel from trees. This slow pace has been a bottleneck for the industry. Researchers from the Norwegian University of Science and Technology have now shortened the process to a few hours.
The information has been collected in the European ECO2 research project. The main objectives of the project were to define principles for carbon footprint assessment, and to assess greenhouse gas impacts of wooden building products and buildings.
Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below. According to the researchers, many wind turbine array studies overlook the fact that important airflow changes occur inside the array.
With winter around the corner some homeowners may be thinking about plugging all the leaks in their home to make them less drafty. Imagine if every homeowner in the country did that -- how much energy could be saved? Using physics-based modeling of the US housing stock, researchers from Lawrence Berkeley National Laboratory found in a new study that upgrading airtightness to a uniform level could achieve as much as $33 billion in annual energy savings.
Straw from agriculture could play an important role in the future energy mix for Germany. Up until now it has been underutilized as a biomass residue and waste material. These were the conclusions of a study conducted by the Thueringian Regional Institute for Agriculture, the German Biomass Research Center, and the Helmholtz Center for Environmental Research.
The predominant view is that CO2 is a waste product, and a polluting one at that, even though small amounts are used to carbonate fizzy drinks, or to make urea or useful industrial solvents. But because of our fossil fuel energy use, we have large amounts of CO2 available that could be put to better use as a resource. This could be done without disrupting the natural carbon cycle, while reusing the carbon to create new products would also decrease fossil fuel use.
Much more is expected of cars and trucks than in the past. Pollution has been cut dramatically and fuel efficiency has risen. That's a difficult feat for manufacturers to pull off, since equipment to reduce pollution typically adds weight, potentially reducing fuel economy.
The California Public Utilities Commission (CPUC) today established an energy storage target of 1,325 megawatts for Pacific Gas and Electric Company, Southern California Edison, and San Diego Gas and Electric by 2020, with installations required no later than the end of 2024.
The EU-funded project BRITER-WATER ('Market replication of bamboo remediation of food industry effluent grey water for re-use') looked at developing and demonstrating an innovative wastewater treatment system using bamboo.
Researchers based at Princeton University found that Earth's terrestrial ecosystems have absorbed 186 billion to 192 billion tons of carbon since the mid-20th century, which has significantly contained the global temperature and levels of carbon in the atmosphere.
