Researchers coax bacteria to make biodiesel | Green Tech - CNET News: "Biofuel start-up LS9 and California researchers on Wednesday claimed a breakthrough in converting non-food biomass into biodiesel using a genetically modified form of e. coli bacteria.
The research, done with the University of California at Berkeley and the U.S. Department of Energy's Joint BioEnergy Institute (JBEI), is a step toward lowering the cost of making biodiesel from wood chips, corn stover, and other residual agricultural products. The group published its results in the journal Nature on Wednesday."

Green Power Island – The Storage Solution for Renewable Energy Overflow | SocialEarth
Green Power Island – The Storage Solution for Renewable Energy Overflow | SocialEarth: "The problem of overflow storage has been a hindrance to the renewable energy industry, namely wind power, but the increasing demand for renewables has opened up new opportunities for technology to meet this challenge. Danish architectural firm Gottlieb Paludan has taken on this issue. They created a low tech solution for storing overflow energy, and have done it with high tech innovation. Green Power Island is the result of careful engineering and design, implementing technology and nature for a sustainable future."

100 Percent Renewable? One Danish Island Experiments with Clean Power [Slide Show]: Scientific American
100 Percent Renewable? One Danish Island Experiments with Clean Power [Slide Show]: Scientific American: "WIND POWER: All told, the wind turbines on Samso supply more power than the residents need--Samso exports 80 million kilowatt-hours of wind-produced electricity annually--thus offsetting some of the island's nonrenewably powered activities, such as its cars, trucks and ferries."

Titanium oxide and carbon nanostructures improve lithium-ion batteries
WWW > News Item: "Titanium oxide and carbon nanostructures improve lithium-ion batteries"
Pacific Northwest National Laboratory and Princeton University researchers devised a method for building tiny titanium oxide and carbon structures that greatly improve the performance of lithium ion batteries. This new material stores twice as much electricity at high charge/discharge rates as batteries that don't use it.

Polymer-ceramic composite electrolyte enables rechargeable lithium-ion battery
WWW > News Item: "Polymer-ceramic composite electrolyte enables rechargeable lithium-ion battery"
The solid electrolyte developed by INL chemist Mason Harrup and his colleagues is a unique mixture of a gel-like polymer ceramic – properly mixing the polymer and ceramic creates a clear membrane. Harrup and his Iteam found that the composite membrane, originally investigated by Eastman-Kodak for antistatic applications, could be sandwiched between two electrodes and act as an electrolyte. The membrane easily conducts positive ions but not electrical current, providing effective electrical insulation with virtually no electrical leak.

Thin-film lithium-ion batteries are rechargeable
WWW > News Item Solid state rechargeable lithium and lithium-ion batteries which are less than 15 µm (micrometers) thick have been developed at the Oak Ridge National Laboratory. These batteries have high energy and power densities, can be cycled thousands of times, and they can be fabricated in arbitrary shapes and to any required size to meet the requirements of a specific application.

India launches Jawaharlal Nehru National Solar Mission
Government of India is launching its ambitious solar energy initiative, the Jawaharlal Nehru National Solar Mission (JNNSM) on January 11, 2010. The highlights of the mission are:
1. Production and deployment of 20,000 MW of solar power by 2022
2. Creation of indigenous capability for solar manufacturing.
3. Off grid operation reaching 1000 MW by 2017 and 2000 MW by 2022.
4. Erecting of solar thermal collectors over 15 million square meters by 2017 and 20 million square meters by 2022.
5. Deployment of 20 million solar lighting systems for rural areas by 2022.
Dr. Manmohan Singh, the Prime Minister of India will launch the Programme today at New Delhi. For more details visit www.mnre.gov.in

Welcome to Renewable Energy Developments.
Fossil fuels like coal, petroleum, and natural gas are fast depleting and may not last over another century at the current levels of consumption. Their use leads to green house gas emissions which produce excessive global warming. Hence the survival of human civilization depends on the deployment of non-polluting and renewable energy sources like the sun,wind, earth and sea. Solar energy, wind energy, geothermal energy, energy from bio-mass, and hydrogen energy are at different levels of development today. Many new forms of sustainable energy may emerge in the future. All of these developments will be discussed here.
