Second Gen Biofuels Most Efficient Use Of EU Bioenergy

July 10, 2013 | By Barbara Vergetis Lundin Bioenergy should be produced in line with EU objectives to use resources more efficiently, according to the European Environment Agency (EEA), including reducing the land and other resources needed to produce each unit of bioenergy and avoiding environmental harm from bioenergy production, extracting more energy from the same material input, and avoiding negative environmental effects potentially caused by bioenergy production. In 2010, bioenergy comprised approximately 7.5 percent of energy used in the EU and is expected to rise to around 10 percent by 2020, according to EU Member States’ National Renewable Energy Plans. According to the EEA analysis, the most efficient energy use of biomass is for heating and electricity as well as advanced biofuels or second generation biofuels. The research shows that the current energy crop mix is not good for the environment and recommends a broader mix of crops to reduce environmental impacts, including perennial crops which are not harvested annually  like energy grasses or short rotation willow plantations to enhance ecosystem services such as flood prevention and water filtration. Bioenergy is often considered carbon neutral, as the carbon dioxide released in combustion is assumed to be compensated by the CO 2 absorbed during plant growth. However, the research shows that indirect land use change can negate any greenhouse gas savings from biofuel production based on energy crops due to the displacement of crop production onto previously unused land, which can lead to the conversion of forests and savannah to agriculture ultimately harming biodiversity and increasing greenhouse gas emissions. “Bioenergy is an important component of our renewable energy mix, helping to ensure a stable energy supply. But this study highlights the fact that forest biomass and productive land are limited resources, and part of Europe’s ‘natural capital,'” Hans Bruyninckx, EEA executive director, said. “So it is essential that we consider how we can use existing resources efficiently before we impose additional demands on land for energy production.” For more: – download the report Read more: Second gen biofuels most efficient use of EU bioenergy – FierceEnergy http://www.fierceene…0#ixzz2YfQfXVKy Subscribe at FierceEnergy Taylor Scott International
