Non-Carbon Sources For Electricity

The British government wants to do something about climate change and their advisors are promoting electricity from non-carbon sources (Black, Richard, "Climate Advisors Take Electric Road,"http://news.bbc.co.uk/2/hi/science/nature/7758752.stm). The Committee on Climate Change advises in a 500-page report that the UK should first wean the power providers off fossil fuels, then invest in electricity from emission-free sources in order to reach greenhouse gas emission targets: "by 80% by 2050" (ibid). Eventually they want to provide emission-free electricity for "'road transport and the heating of buildings'" (ibid).

It can be done--in the UK, the US, and everywhere--and much sooner than 2050. For more information, please see www.campaignforgreen.com.

Biomass Limitations and the Alternative

Biomass, which includes buring wood for fuel, has its limits (http://news.bbc.co.uk/2/hi/science/nature/7997398.stm). If not done sustainably, we could end up with more greenhouse gas than we have had with fossil fuels: "At its best, biomass could produce as little as 27kg of CO2 (equivalent) per megawatt hour - 98% less than coal, saving around two million tonnes of CO2 every year . . . However, the study also found that in some cases overall emissions could be higher than those of fossil fuels" (ibid). But it could be used in combination with other things (ibid).
Why bother, though, with something so difficult when there's a totally green, totally emissions-free alternative? For more information, please see www.terrahumanafoundation.org.
