Where you live could mean 'greener' alternatives do more harm than good

Whether it's swapping your car for an electric vehicle, or your natural gas furnace for geothermal heating, transitioning from fossil fuels to electric-powered technology is widely believed to be the best way to lower carbon emissions. But knowing where the electricity comes from to power those 'eco-alternatives' is critical. If that electricity comes from burning oil and coal, it might mean that green alternatives aren't that green after all.

Water in smog may reveal pollution sources

The chemical signature of water vapor emitted by combustion sources such as vehicles and furnaces has been found in the smoggy winter inversions that often choke Salt Lake City. The discovery may give researchers a new tool to track down the sources of pollutants and climate-changing carbon dioxide gas.

The biobattery

Sewage sludge, green waste, production residue from the food industry, straw or animal excrement - with the biobattery's modular concept a much larger range of biomass can be utilized for energy recovery than previously. Researchers show that they can convert organic residues into electricity, heat, purified gas, engine oil and high quality biochar using this process.
