Vested interests versus renewable energy (book)
Renewable Energy Transformation or Fossil Fuel Backlash? Vested Interests in the Political Economy
Renewable energy is rising within an energy system dominated by powerful vested energy interests in fossil fuels, nuclear and electric utilities. Analyzing renewables in six very different countries, the author argues that it is the extent to which states have controlled these vested interests that determines the success or failure of renewables.Wednesday, 18 June 2014
Low input maize for biofuel (#journal)
Efficient biofuel production from traditional maize under low input
Traditional crop varieties are adapted to low inputs of fertilizers, pesticides, and water. The authors tested the suitability of traditional maize varieties as solid biofuel, cultivating traditional maize varieties without pesticides and irrigation and then measuring the heating value, the ash content, and the elemental composition. Results show that plants harvested at maturity, 150 days after sowing, have about 10 % more biomass and 20–30 % less ash, N, K, and Cl than plants harvested 115 days after sowing. Traditional maize varieties can produce an energy of 15–23 · 104 MJ/ha. These findings demonstrate that traditional maize cultivation can be optimized to increase the efficiency of biomass production and to reduce the environmental impact.
