We have selected most recent peer-reviewed publications showing that biomass stoves implementation can improve household income and reduce deforestation caused by uncontrolled fuelwood collection.
The European Union assembly fixed a 6 percent limit on the use of crop-based biofuels in ground transport, seeking to spur the development of clean fuels from non-food sources.
From food debate and land use changes effects to biofuels sustainability, a lot of scientific findings show great differences among alternatives. We joined best scientific information.
Following our recent post on sustainability and land use changes, we include here a new study on land use changes that challenges the EU commission regarding biofuels.
A very recent research publication found harvested area with food crops to be increasing during 2000-2010 period simultaneously with biofuel expansion.
Lignocellulosic crops have shown in recent decades a more efficient pathway to produce energy and also lower environmental impacts. Life cycle assessments show that fertilizers efficiency is critical as well as expected yields and extractions levels when producing energy crops. We discuss implications and criteria to apply.
A semiarid country like Spain, often have very low grain yields and per hectare income from winter cereals. Since a 16MW straw based power plant in Bivriesca, Burgos, started 200.000 tons/yr and 12M € have been part of the local economy.
Most recent developments and scientific evidences regarding biofuels’ impacts and sustainability but also methods to evaluate land use changes and bioenergy sustainability have been showing truly complex discussions.
The sustainable use of energy crops for biogas is a possible solution to reduce the contribution to climate change of human activities. Power based on biomass, in particular biogas, is increasing, with a concomitant increase in the need for energy crop production.
The Chinese National Energy Administration (NEA) has unveiled its 12th five-year plan for renewable energy. Unsurprisingly, the plan focuses on the mature renewable technologies of hydropower, wind power, solar energy and biomass.
