The need for alternative and renewable transportation fuels continues to be high on the nation's agenda. Substituting these fuels for petroleum can reduce dependence on foreign oil imports, improve air quality, and mitigate greenhouse gases. Renewable fuels offer the same advantages as...

The first objective of this paper is to update earlier assessments of mineral dependence in lower-income countries. In 2018, the mining of metals and coal continued to be an important contributor to the economies of several low- and middle-income countries. As in our previous calculations of the...

This paper explores the potential impacts of the transition to a low-carbon future for the taxation of extractive resources. The global debate on climate change has firmly moved on from the question of whether countries ought to shift towards such a future to that of how they are going to...

Greenhouse gas emission reductions are at the centre of national and international efforts to mitigate climate change. In road transportation, many politically incentivised measures focus on increasing the energy efficiency of established technologies, or promoting electric or hybrid vehicles....

European Union supports alternative fuels, in particular, biofuels to comply with the triple objective of reducing greenhouse gases emissions, diversifying fuel supply and developing long-term replacements for fossil fuels. The European Community set the goal to substitute 20% of the fossil...

The National Renewable Energy Laboratory's (NREL) process development unit has been operating since 1995 to test technology to convert lignocellulosic biomass to fuel ethanol. Following this type of testing, a pre-commercial scale engineering demonstration is likely to be needed to demonstrate...

The effects of ethanol addition to gasoline on an SI engine performance and exhaust emissions are investigated experimentally and theoretically. In the theoretical study, a quasi-dimensional SI engine cycle model, which was firstly developed for gasoline-fueled SI engines by author, has been...
