New device, announced at Mobile World Congress in Barcelona, will include a 50% reduction in standby energy consumption + description of solar powered phone by Samsung

M-Farm service helps small-scale farmers get price information that will help them know where to get the best deal for their products through their mobile phones

"The objective of this study is to:  compile the available recent literature on ILUC emissions;  compare these emissions with the assumed gains of biofuels;  assess how ILUC changes the carbon balance of using biofuels;  formulate policies to avoid these extra emissions associated with ILUC. Trends in land use, with and without biofuels All the studies on global agricultural markets reviewed predict that new arable land will be required to meet future global demand for food and feed. Although there will be increased productivity on current arable land (intensification), food and feed demand will probably grow faster, which means that mobilization of new land is likely to occur. Biofuels produced from crops (the current mainstream practice) will add extra demand for crops like wheat, rice, maize, rapeseed and palm oil. This will increase prices for these crops (as well as for land) and lead to two impacts: intensification of agricultural production and conversion of forests and grasslands to arable land. In this report we consider the issue of indirect land use change initiated by EU biofuels policy and seek to answer the following questions:  What is the probability of biofuels policies initiating land use changes?  What greenhouse gas emissions may result from indirect land use change, expressed as a factor in the mathematical relation given above?  What technical measures can be applied and what policy measures adopted to limit or entirely mitigate indirect land use change and the associated greenhouse gas emissions? We first (Chapter 2) broadly discuss the mechanism of indirect land use change. We next discuss why there is a perception among stakeholders that there is a serious risk that EU biofuels policy will initiate indirect land use change (Chapter 3) and consider the figures cited by other studies as an indication of the magnitude the associated greenhouse gas emissions  (Chapter 4). We then broadly consid

A recent study by Logan group at Penn State University also demonstrated similar findings in that the energy contained in hydrogen gas not only can offset the energy used for the desalination process but has surplus that can be used for downstream processing.

Several years ago even the mobile phones were very expensive, not to mention computers and airplane flights.

The example of mobile phones is of little relevance here, because cost reduction is driven by the scaling laws of microelectronics. However, the reducing cost of flights - in a way the ultimate energy application - offer a good benchmark. What will happen to flights though if commodity and energy prices go up in the long run?

1.7 kWp, 2000kWh per year. How many cars per annum can you charge at, say, 5KWh each? Better stick to bicycles and phones!

South Tyrol gets serious about solar mobility: The "E-Move Charging Station", a pilot project of the Bozen entrepreneur Valentin Runggaldier, is to supply electrically operated bicycles, scooters, cars and even mobile phones with the necessary "fuel" from the sun. The solar charging stations were designed by Michael Scherer from Brixen

Aren't the terms '50' and 'Manhattan project' in the same sentence an apparant contradiction. If we have to invent the atomic bomb 50 times, we'd be in real trouble.

The event, known as the Capitol Climate Action (CCA), will be the largest mass mobilization on global warming in the country's history. The event reflects the growing public demand for bold action to address the climate and energy crises. It means no more waiting, no more excuses, and no more coal.

21-year-old student Emily Cummins has created a portable solar-powered fridge specifically for use in developing countries.

The spaghettilike nightmare that forms many consumers' collection of phone chargers, headset connectors and data cables could be set to end after a major mobile-industry forum agreed to standardize on one type of connector.

A small backward step for copper, but a giant leap forward for sustainability. Now do the same thing for laptops please.
