Study Aims to Spur Energy Savings, Reduce Emissions in U.S. Cities

A new NREL study provides insight into actions being taken to reduce energy use and emissions in 20 U.S. cities, highlighting additional steps they can take.

Analysis Shows Benefits, Costs of Climate Change Action, Inaction

12,000 deaths a year in 49 US cities could be avoided if strong actions to reduce GHG emissions and address climate warming, according to a peer-reviews analysis released Monday by the EPA’s Climate Change Impacts and Risk Analysis project. That’s just one benefit. Compared to a scenario of inaction, taking strong climate action would avoid approximately 13,000 deaths in 2050 and 57,000 deaths annually in 2100 from poor air quality. Delay will result in these costs rising over the course of the 21st century, the report says.

More Wind & Solar Can Reduce Utility Costs and Emissions

Those opposed to spurring development and adoption of renewable solar and wind energy resources continually assert that their intermittent nature not only reduces grid reliability and raises the cost of electricity, but negates the carbon and greenhouse gas emissions reductions that contribute so greatly to their rapid adoption in the first place. While it’s true that bringing greater amounts of…

More efficiency is possible using quantum dot solar cell technology

Quantum Dot Solar Cells Show Promising Results

Conventional solar cells capture photons in sunlight and turn it into electricity. This is also true for solar cells that use quantum dots as the photovoltaic material, but with quantum dots, it`s actually possible to harvest “lost” energy that otherwise would end up as heat. This feature is promising to improve overall conversion efficiency of solar cells, which in turn will…

US, Iceland & New Zealand Launch Renewables Pilot Projects in the Caribbean, South Pacific

Iceland, New Zealand and US teams, part of the EDIN partnership to help island nations develop and make a transition to renewable energy powered economies and societies announced its first three pilot projects last week.

New Orleans Gets Smart on Energy as it Rebuilds

Energy efficient buildings and solar power are key elements of efforts to rebuild and revitalize New Orleans. The Dept. of Energy and National Renewable Energy Lab are joining with other public and private sector organizations as the “Big Easy” recovers from the aftermath of Hurricane Katrina.

Bringing Down the Cost of Solar PV: A Match Made in Heaven?

It’s like that serendipitous combination of chocolate and peanut butter, only the Dept. of Energy’s National Renewable Energy Lab and Optony are purposely setting out to combine their leading edge efforts to bring down the costs of solar power by wedding the former’s record-setting thin-film solar photovoltaic (PV) cells with the latter’s concentrating solar power (CSP) system. NREL and Optony…
