While water-related conflicts and shortages abound throughout the rapidly changing societies of Africa, Asia and Latin America, there is clearly sufficient water to sustain food, energy, industrial and environmental needs during the 21st century, argues the Challenge Program on Water and Food (CPWF) of the CGIAR in two special issues of the peer-reviewed journal, Water International (Volume 35, Issue 5 and Volume 36, Issue 1), released at the XIV World Water Congress.
Scientists at Cambridge University are exhibiting a prototype table that demonstrates how biological fuel cells can harness energy from plants.
Because costs of trash collection have increased significantly while landfill space diminishes, radio frequency identification (RFID) holds the potential to dramatically reduce the volume of trash and increase the amount of materials being recycled.
Global emissions of carbon dioxide (CO2) increased by 45 percent between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010. Increased energy-efficiency, nuclear energy and the growing contributions of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries.
Even though many view environmental protection as coming with an extra cost, a California caterer has managed to cut costs tremendously by going green.
Modifying soybean seed to increase phosphorus content can improve animal nutrition and reduce feed costs and nutrient pollution. However, further research is needed to commercialize this valuable technology.
Deforestation in the rainforests of West Africa reduces rainfall over the rest of the forest, according to new University of Leeds research published in Geophysical Research Letters. The study shows that changing land use from forest to crop land reduces rainfall over neighboring trees by about 50 percent due to changes in the surface temperature, which affects the formation of rain clouds.
Our most reliable models rely on data acquired through a range of complex measurements. Most of the important measurements - such as ice cover, cloud cover, sea levels and temperature, chlorophyll (oceans and land) and the radiation balance (incoming to outgoing energy) – must be taken from space, and for constraining and testing the forecast models, made over long timescales.
the Energy Department has awarded more than $30 million to 24 universities in 23 states across the country to train undergraduate- and graduate-level engineering students in manufacturing efficiency to help these students become the nation's next generation of industrial energy-efficiency experts.
The new material can store and release hydrogen extremely fast and at low temperatures compared with similar materials, and it's rechargeable. These attributes could make it ideal for use in onboard hydrogen storage for next-generation hydrogen or fuel cell vehicles.
Capturing CO2 from power stations and storing it deep underground carries no significant threat to human health, despite recently voiced fears that it might, a study has shown.
The past decade has seen 77,951 fires burn about 6.7 million acres in the United States. One condition that facilitates the spread of wildfires is invasive plant species. Nonnative weeds can modify the vegetation of a landscape and provide a source of fuel that did not previously exist.
Today’s wireless-sensor networks can do everything from supervising factory machinery to tracking environmental pollution to measuring the movement of buildings and bridges.
A team of students from Embry-Riddle Aeronautical University demonstrated a first in aviation history.
The list highlights vulnerable elements where global production is concentrated in a small number of countries, including metals that are critical to development of a low-carbon digital economy. The list helps to focus future research on diversifying supply from new resources, using greener production technologies and cost-effective recycling.
The project is slated to be the first plant in the United States to produce GTL transportation fuels and other products.
Alternative fuel sources for cars may have a glowing future as a Kansas State University (K-State) graduate student is working to replace petroleum fuels with ones made from sunlight.
The Empire State Building has been awarded LEED® Gold for Existing Buildings certification as further recognition from the $550 million Empire State ReBuilding program.
California beach towns could face hefty economic losses caused by sea level rise in the next century, according to a new state-commissioned study.
