Currently, the world economy and western society in general runs on fossil fuels. We've known for some time that this reliance on finite resources that are polluting the planet is unsustainable in the long term. This has led to the search for alternatives and hydrogen is one of the leading contenders. One of the problems is that hydrogen is an energy carrier, rather than an energy source. Pure hydrogen doesn't occur naturally and it takes energy - usually generated by fossil fuels - to manufacture it. Now researchers at Pennsylvania State University have developed a way to produce hydrogen that uses no grid electricity and is carbon neutral and could be used anyplace that there is wastewater near sea water.

There are a number of reasons that many people are opposed to fish farming. Among other things, they claim that the caged fish release too much concentrated waste into the surrounding waters, too many antibiotics and anti-algal chemicals are used, the ecological balance is upset when non-native fish escape from their pens, and strain is put on populations of local fish that are captured for use in feed for carnivorous farmed fish. Unfortunately, wild-fish-capturing methods such as drift net fishing and bottom trawling have big problems of their own. A new system that involves raising fish in mesh spheres that float in the open ocean, however, is claimed to sidestep many of the drawbacks of traditional marine aquaculture. The Velella Research Project is pioneering the technology. Read More

The Climate Reality Project (formerly known as the Alliance for Climate Protection) has just kicked off its "24 Hours of Reality" live streamed event. The presentation runs 24 hours, is available live in 13 languages, and is the beginning of a worldwide campaign to present the latest information about the climate crisis and reject misinformation.

In the wake of the Fukushima Daiichi nuclear disaster, tens of thousands of German citizens took to the streets calling for the phase out of atomic energy. In May, the German government bowed to public pressure and unveiled its plan to shut down the country's 17 nuclear power plants by 2021 - with the possibility that three will continue operating until 2022 if the transition to renewable energy doesn't go as quickly as hoped. Providing some hope that Germany will achieve its ambitious goals, Spiegel Online International has quoted a newly released German Association of Energy and Water Industries (BDEW) report that says, for the first time, renewable sources accounted for more than 20 percent of the country's electricity generation in the first half of 2011.

While some see carbon capture and storage as akin to sweeping CO2 emissions under the carpet, others believe it is a necessary short-term solution in the transition to a clean energy future. Last week, ground was broken on construction of the U.S.'s first large-scale industrial carbon capture and storage (ICCS) facility that aims to demonstrate that CO2 emissions can be stored permanently in deep underground rock formations.

Hopefully, your old newspapers don’t just end up in the landfill. In the future, however, they might not even be used to make more paper – instead they may be the feedstock for a biofuel-producing strain of bacteria. Named “TU-103,” the microorganism was recently discovered by a team of scientists at New Orleans’ Tulane University. It converts cellulose – such as that found in newspapers – into butanol, which can be substituted for gasoline. Read More

There’s no doubt that skylights make for psychologically-nicer buildings, while also reducing the amount of electricity required for daytime artificial lighting. If they let in too much sunlight, however, they can actually increase the amount of electricity needed for air conditioning. California-based EnFocus is attacking the situation from two ends – its Diamond-Power panels diffuse sunlight to keep interior heat down, while also harnessing it to create electricity. Read More

In a world increasingly concerned with waste, the smart manufacturers are identifying ways of utilizing the by-products of manufacturing and creating two products from one process. One example – a graduate student in agriculture at the Hebrew University of Jerusalem has developed a way of creating foam from the waste from paper mills, radically reducing waste from paper production and creating two products that are highly valuable and in demand.

Ecotricity has unveiled plans to install green-energy-powered electric vehicle (EV) charging points at selected motorway service stations running up the UK's automotive backbone. Aiming to end potential range anxiety and speed up the adoption of EVs in Britain, the national network of charging posts will be rolled out to every Welcome Break service station, as well as other key locations, in the UK by the end of the year. Each charging post will receive its power from the company's wind and solar parks across the country, and one of the first three to go live is directly connected to the resident wind turbine at Reading's Green Park business park - offering electric motorists true zero emission driving.
