  • Mining the Soil for Biomass Energy

    Min­ing the Soil for Bio­mass Ener­gy — Thurs­day, April 16 at 1 pm PT / 4 ET Jon Rhodes, water­shed hydrol­o­gist, has more than thir­ty years of pro­fes­sion­al expe­ri­ence eval­u­at­ing the impacts of log­ging and road build­ing on for­est ecosys­tems and water­sheds. Jon runs Plan­e­to Azul Hydrol­o­gy, which pro­vides afford­able water­shed exper­tise for a wide vari­ety of con­ser­va­tion…

  • Biomass: The Unsustainable Energy Source

    - by Atheo, Aletho News The pro­mo­tion­al mate­r­i­al from Big Green Ener­gy, aka Bio­mass Gas & Elec­tric, presents bio­mass as “clean, renew­able ener­gy,” sus­tain­able and green. The US Depart­ment of Ener­gy uses the terms “clean and renew­able” when intro­duc­ing vis­i­tors at its web­site to the topic. But is it accu­rate to describe the repeat­ed removal of bio­mass…

  • Soil Erosion May Get Us Before Climate Change Does

  • Study: Logging Destabilizes Forest Soil Carbon

    - by John Cramer, Decem­ber 2, 2014, Dart­mouth College Log­ging does­n’t imme­di­ate­ly jet­ti­son car­bon stored in a forest’s min­er­al soils into the atmos­phere but trig­gers a grad­ual release that may con­tribute to cli­mate change over decades, a Dart­mouth Col­lege study finds. The results are the first evi­dence of a region­al trend of low­er car­bon pools in soils…
