...company discarded the old extractive-industry model and formed a power-generation arm to build biomass power stations for Liberia, starting with a 35-megawatt station for Monrovia due to be switched on in 2010. (The capital's million or so residents currently make do with just two megawatts...
...emerging as a leader in electric cars, solar power and wind power. South Korea is not yet known for anything environmentally friendly, but that is about to change. The South Korean government is spending $31 billion to fund research in 27 green technologies, including non-silicon-based solar cells, biomass fuels and carbon collection, storage and processing. (See the top 10 green stories...
...President Barack Obama appears to recognize the tectonic shift. Part of Washington's $787 billion stimulus spending is meant for green initiatives: $2 billion to support lithium-ion batteries and hybrid electric systems, $800 million for a biomass program, $400 million to add electric technologies to vehicles and $400 million for geothermal technologies. But with public debt now equal to 82% of GDP and the budget deficit forecast to hit $1.4 trillion next year, the U.S. is in no position to spend more...
...carbon, too, bioelectricity was a winner. On average, the carbon offset from using bioelectricity is 100% bigger than the offset for using ethanol. (Even though biomass releases carbon when it is burned, just like oil, when new plants are growing they absorb carbon dioxide from the atmosphere, reducing the overall carbon footprint.) "It's simply the case that bioelectricity is just a lot more efficient than using ethanol, in most ways," says Campbell...
...Science study doesn't take into account other impacts that bioelectricity might have compared to ethanol, like water consumption or air pollution. Growing biomass, even on marginal agricultural land, does require water, as does making electricity. There's a bigger problem - electric cars still remain few and far between, while there are already millions of U.S. vehicles on the road that can run on an ethanol blend. Creating the sort of infrastructure that can support electric cars on a mass scale won't be cheap, and it's not a cost that Campbell and his colleagues included in their study...
