In a breakthrough, scientists have developed a new low cost, efficient and environment-friendly solar cell that uses tin instead of the hazardous lead.

Researchers from Northwestern University are among the first to create a solar cell that uses a structure called perovskite, with tin as the light-absorbing material instead of lead.

"Exculding the use of lead is a quantum leap in the process of creating a very promising type of solar cell called a perovskite," said Mercouri G Kanatzidis, an inorganic chemist with expertise in dealing with tin.

hailstate.com - April 30, 2014

STARKVILLE, Miss. -- A day after destructive tornadoes swept through the state of Mississippi, Mississippi State student-athletes from all sports responded as volunteers in the relief efforts.

MSU student-athletes, graduate assistants, athletic department staff, weight room staff and equipment staff quickly set up a tornado relief center and shelter in the parking lot of the Palmeiro Center on the MSU campus. The relief center is being coordinated by the Mississippi Emergency Management Agency.

Government underpins £12bn investment in renewable energy

Walney offshore windfarm named in first wave of green energy projectsImage: Walney offshore windfarm named in first wave of green energy projects

clickgreen.org.uk - April 23rd, 2014

The UK Government has announced the first wave of renewable electricity projects to receive financial guarantees, providing a huge boost to the nation’s green growth and green jobs.

By 2020, the eight projects unveiled today will provide up to £12 billion of private sector investment, supporting 8,500 jobs, and they could add a further 4.5GW of low-carbon electricity to Britain’s energy mix, or around 4% of capacity.

The five offshore wind farms and three biomass power plants have progressed through the Final Investment Decision Enabling for Renewables (FID-ER) process, and have been offered contracts for financial support.

11 Innovative Companies Giving Energy Storage a Jolt

      

PowerFactor is part of GridSTAR, a demonstration smartgrid project deployed at the Philadephia Navy Yard.

greenbiz.com - by Garrett Hering - April 21, 2014

Technological and market forces have converged to make energy storage one of the most exciting — and potentially game-changing — opportunities for commercial and industrial facility managers, grid operators, homeowners and investors.

Forward-thinking utilities, battery suppliers, power inverter producers, system integrators and public-sector supporters are driving a massive expansion of energy storage solutions aimed at enabling the grid of the future — or even a grid-less future.

Although the energy storage value chain includes hundreds — if not thousands — of players, the following are leading the charge.

Scientists Discover How to Generate Solar Power in the Dark

Meet 'photoswitches,' a breakthrough set of materials that act as their own batteries, absorbing energy and releasing it on demand.

theatlantic.com - by Todd Woody - April 15, 2014

The next big thing in solar energy could be microscopic.

Scientists at MIT and Harvard University have devised a way to store solar energy in molecules that can then be tapped to heat homes, water or used for cooking.

The best part: The molecules can store the heat forever and be endlessly re-used while emitting absolutely no greenhouse gases.

Killing superbugs dead with “molecular drill bits”

Submitted by Luis Kun

homelandsecuritynewswire.com - March 18th, 2014

Tuberculosis (TB) is a well-known, treatable disease, but resistant strains are cropping up. The World Health Organization (WHO) estimates that about 170,000 people died from multidrug-resistant TB in 2012. In response to drug-resistant “superbugs” that send millions of people to hospitals around the world, scientists are building tiny “molecular drill bits” which kill bacteria by bursting through their protective cell walls.

NCFPD Webinar - Community Resilience and Impacts of Interdependent Infrastructure Disruptions as Experienced from Hurricane Sandy

       

ncfpd.umn.edu - Friday, April 4, 2014

Under the dynamic conditions of rapid climate change and broader global changes, resilience and sustainability are not being achieved through traditional emergency management and humanitarian approaches alone. While community-based resilience networks are now beginning to emerge in a race to stabilize New York City's coastal communities significantly impacted by Superstorm Sandy in 2012, many impacted neighborhoods are still trending toward greater vulnerability plaguing recovery and preparedness for the next wave of potentially larger storms.
