The transport sector represents a major item on the global balance of greenhouse gas (GHG) emissions. Natural gas is considered the alternative fuel that, in the short-medium term, can best substitute conventional fuels in order to reduce their environmental impact, because it is readily...

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...

I explain the recent peak and subsequent collapse in oil prices by strategic interaction between a limit-pricing oil cartel and an importer producing substitutes to oil, with productin costs falling with R&D investment. The model is consistent with reported narratives of the oil price collapse....

Oil seed plants have been one of the biomass sources of fuel. Vegetable oils may be employed in CI engines as an alternative fuel. In this study, diesel fuel properties of sunflower oil were determined and long term engine tests of sunflower oil were performed. Engine tests were conducted at a...

Advances in renewable alternative biomass-based fuel technologies make their commercialization likely within a decade. Substituting fuels derived from biomass for fossil fuels can reduce dependence on petroleum use, improve air quality, mitigate global warming, and strengthen a weak farm...

The Fukushima disaster has lead the French government to release novel cost information relative to its nuclear electricity program allowing us to compute a levelized cost. We identify a modest escalation of capital cost and a larger than expected operational cost. Under the best scenario, the...

The proper use of alternative fuels and materials in the cement industry is essential for the planning and promotion of different methods that can decrease the environmental impacts, lower the consumption of energy and material resources, and reduce the economic costs of this industry. Because...

Petroleum industries produce more byproduct sulfur than the market can absorb. As a consequence, most sulfur mines around the world have closed down, large stocks of yellow sulfur have piled up near remote operations, and growing amounts of toxic H2S are disposed of in the subsurface. Unless...
