Transitioning from a carbon-intensive economy to a low-carbon future presents challenges and opportunities for developing countries. The Sustainable Energy Roadmaps help countries successfully navigate the change to an infrastructure capable of meeting the energy challenges of the 21st century.
The approach examines a country’s potential for renewable energy production such as wind, solar, small hydropower and biomass. Existing energy infrastructure is analyzed to identify the potential for, and hurdles to, increased efficiency and energy storage. At the same time, current socio-economic and policy environments are factored into the analysis to identify barriers to low-carbon development and determine international best practices to suggest how they can be overcome. Equally important, funding options that might be available from private, public, and multilateral institutions to help bring renewable energy projects into being are assessed.
The project strengthens government and civil society capacity, enhances stakeholder engagement, and advances policies that combat climate change...

With Superstorm Sandy leaving so many without power for days on end, a lot of people are thinking harder about what alternative energy solutions they should add to their emergency kits. We have quite a few suggestions for where to start looking for the best options.
First, check out our 5 Best Portable Solar Laptop Chargers. These are great options for laptops from companies like Brunton, Go Power, and Sunlinq, and you can also use them to charge up smaller devices like cell phones. The prices make them an investment but they'll get the job done.
Next, we like the solar chargers launched by Swiss Army. It folds up nicely to fit in an emergency backpack and is a much lower price tag. But that also means less charging capability. It'll work for cell phones, flashlights, extra batteries and radios, but it would take ages to charge something as large as a laptop.
Solar thermodynamic panels are an exciting innovation in renewable energy for heating in homes and businesses. This technology has been in development and use for 30 years in Scandinavian countries and is now entering the U.K. market. In addition to savings on electricity and fossil fuel bills, installing solar thermodynamic panels makes homeowners and businesses eligible for government backed energy incentive rebate schemes for the cost of installation.

(Phys.org)—Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today's electricity expenses, according to new research by the University of Delaware and Delaware Technical Community...
Princeton researchers have found a simple and economic way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.
Chou said the research team used nanotechnology to overcome two primary challenges that cause solar cells to lose energy: light reflecting from the cell, and the inability to fully capture light that enters the cell. With their new metallic sandwich, the researchers were able to address both problems.
The sandwich – called a subwavelength plasmonic cavity – has an extraordinary ability to dampen reflection and trap light. The new technique allowed Chou's team to create a solar cell that only reflects about 4 percent of light and absorbs as much as 96 percent...

Neuf industriels s’associent sous la direction de Panasonic pour construire 1 000 foyers qui redéfiniront l’urbanisme écologique. Construit sur un ancien site industriel japonais, ce projet ambitieux s’appuiera sur un florilège de technologies propres. Cette ville côtière nommée Fugisawa est située à 50 km à l’ouest de Tokyo.
Even as more affordable photovoltaics and government incentives for adopting renewable energy sources have made solar a financially attractive alternative in some areas, it can still be hard to find accurate, easy-to-understand information to help make the leap. The Solar Tool, developed by the Sustainable Design Lab at MIT and Boston-based design workshop MoDe Studio, aims to solve that problem for the city of Cambridge. Simply enter your address, and a comprehensive satellite map of Cambridge shows you how efficient your own
rooftop is for soaking up the sun’s rays, from excellent to poor, down to the square meter.
