Green Options

Australian scientists at CSIRO’s Victorian Organic Solar Cell Consortium (VICOSC) are on a quest to make solar cells as easy to print as money. Trials of the flexible, large area, cost-effective, reel-to-reel printable plastic solar cells will even be conducted by Securency International — a banknote printing company.

Australian researchers have figured out a cool new way to tackle the threat of global warming, by setting up a network of ‘talking’ fridges.

But wait, the idea isn’t as crazy as it might sound. The fridges feature cutting-edge technology enabling them to communicate with each other via a network to share and store energy from renewable energy sources such as solar panels or wind turbines.

According to inventor, Sam West, “The fridges are designed to talk to each other, negotiating when it’s a good time to consume electricity and when it’s better not to.”

According to The Guardian, Fatih Birol, Chief Economist with the International Energy Agency (IEA), has candidly revealed his position that world oil demand will start outpacing supply “around 2020.”

Peak Oil — that most controversial and elusive of concepts. Everybody seems to have their own opinion. There are experts on both sides who alternately claim we have at least 30 years before we reach it and those who claim we’ve already reached it.

So, for a top-level official in an agency with the respect of the IEA to state that we’ll reach an oil supply plateau around 2020 is pretty substantial news — especially considering that his own agency has previously stated that the date was 2030.

Editor’s Note: I’m in Houston, TX, this week, celebrating the International Year of the Planet by posting on topics covered at the first ever joint meeting between the American societies of Soil Science, Geology, Crop Science and Agronomy. With a significant focus on biofuels, this conference should be rife with interesting materials.

According to Dr. Peter McCabe, a world-renowned scientist currently working at CSIRO in Australia, any realistic analysis of future energy sources can only conclude that, barring some complete and miraculous harmony between all the world’s economic superpowers, fossil fuels will dominate our energy mix for at least the next few decades — and we should just accept it.

To get a perspective on where Dr. McCabe is coming from, it struck me that he is a man who thinks in terms of quadrillions of BTUs and exajoules of energy. His views come from an analysis of global markets and global energy use. To him it probably seems that a grassroots coordinated global effort is beyond the reach of humanity.

Being a bit of a realistic skeptic myself, it seemed like it would be worth my while to temporarily suspend my deep held belief that not only is it possible for the U.S. and most of the rest of the world to kick its oil habit within a decade, but also a simple requirement for survival, and take Dr. McCabe at face value.

It seems like new reports are practically coming out daily about the next great gasoline alternative— furfural, algae, and switchgrass, just to name a few. Now 3 more contenders have entered the ring: leaves, twigs, and bark.

Australia’s Commonwealth Science and Research Organization (CSIRO) reports that lignocellulose, a component of plants and wood, could potentially be used as a cheap fuel—as inexpensive as $40-60 a barrel.

Even better, lignocellulose biofuels are compatible with current facilities. All they need for conversion is an extra unit in front of any existing sugar biofuel facility.
