Windows with transparent photovoltaic modules or façades in which microalgae are being bred to provide the house with its own biofuel are just some of the aspects buildings of the future could feature. 

A new international research effort, coordinated by  Friedrich Schiller University in Jena’s materials scientist Lothar Wondraczek, is aiming to change this. In the project ‘Large-Area Fluidic Windows – LaWin’ the scientists intend to develop functional façades and window modules, together with an integrated production process to achieve an as to yet unmatched readiness to market.

Though the New York governor recently made a pretense of banning fracking in the state (it was already not allowed) and the California governor said they should do the same thing, they're both being a little hypocritical. New York would have brown-outs without the energy they buy from Pennsylvania fracking and California has no fracking and 50 percent higher utility costs than the rest of the country because they subsidize alternatives and have to buy so heavily on the spot market.

American CO2 levels are down and while some contend it is more due to federal economic mismanagement and unemployment than cleaner natural gas, emissions from coal, the dirtiest energy source, are back at early 1980s, and natural gas gets credit for that.

Leading conservationists from around the world have called for environmental lobbyists to stop blocking nuclear energy in defiance of the science consensus. It's clean, it's green, and it's needed to mitigate climate change and protect biodiversity.

In an open letter to environmentalists, over 60 scientists ask the environmental community to "weigh up the pros and cons of different energy sources using objective evidence and pragmatic trade-offs, rather than simply relying on idealistic perceptions of what is 'green'".

Organized by ecologists Professor Barry Brook and Professor Corey Bradshaw from the University of Adelaide's Environment Institute, the letter supports their recent article (DOI: 10.1111/cobi.12433) in Conservation Biology.

Wind farms like this one probably wouldn't exist if the government didn't provide a hefty subsidy. Shutterstock

Congress passed the wind production tax credit (PTC) more than two decades ago to spur development in an industry still in its infancy. The wind sector has since matured into adulthood, prompting thousands of turbine farms to sprout in fields across the country.

A British “poo bus” went into service last week, powered by biomethane energy derived from human waste at a sewage plant.

There is no shortage of shouting and dire warnings about the state of the climate and our need to phase out fossil fuels. But there is a more silent revolution happening too — in micropower.

Bacteria are everywhere and so efforts to make cleaner energy using them are ongoing.

A report today shows how electrons hop across otherwise electrically insulated areas of bacterial proteins, and that the rate of electrical transfer is dependent on the orientation and proximity of these electrically conductive 'stepping stones'. It is hoped that this natural process can be used to create viable 'bio batteries' which could produce energy for portable technology such as mobile phones, tablets and laptops - powered by human or animal waste. So using your tablet on the toilet would then make even more sense.

Remember the big, somewhat bulky Mercedes Benz cars of the early 1990s?
