Biofuel boost
permafrost). Of the remainder, the vast majority is groundwater, so that just 0.4 per cent of the world's total freshwater is available at the surface as lakes, soil moisture, air humidity, marshes, wetlands, rivers and biomass. And water is proving an increasingly critical component in agricultural activities. Earlier this month, the Chinese government declared an emergency for the first time ...
متن کاملBiofuel boom
A recent report by the Earth Policy Institute estimated that one quarter of the US corn crop is being channelled into biofuel production, raising fears of increased food prices and worldwide hunger. An excerpt from the report reads, “The amount of grain needed to fill the tank of an SUV with ethanol just once can feed one person for an entire year. The average income of the owners of the world’...
متن کاملIi. Greenhouse Gas Markets, Carbon Dioxide Credits and Biofuels A. Ghg Policies as a Way to Boost Biofuel Demand
The previous chapter analysed mandatory blends and utilization targets as policy measures that can provide incentives for expanded biofuels production. GHG policies that create a carbon price either through an emissions trading system or directly by taxing GHG emissions also generate increased demand for biofuels. They do so by raising the price of burning the fossil fuels with which biofuels c...
متن کاملGlucose-based Biofuel Cells: Nanotechnology as a Vital Science in Biofuel Cells Performance
Nanotechnology has opened up new opportunities for the design of nanoscale electronic devices suitable for developing high-performance biofuel cells. Glucose-based biofuel cells as green energy sources can be a powerful tool in the service of small-scale power source technology as it provides a latent potential to supply power for various implantable medical electronic devices. By using physiol...
متن کاملAn Optimization Model for Biofuel Supply Chain
Biofuels have attracted much attention as a sutuible substitute for fossil fuels in last decade. Designing an efficient supply chain is an essential requirement for commercialization of biofuel production. This paper presents a mixed integer linear programming (MILP) model to design biofuel supply chains in which the biofuel demand is under ARMA time series models. It is studied how ARMA time s...
