Globally, with the rapid growth of population, use cars is also increasing. Although there an increase in electric vehicles, vast majority vehicles used are internal combustion engine vehicles. Fossil fuel have disadvantages such as damaging environment due to their high emission values, using non-renewable energy sources fuel, maintenance costs, and complex vehicle structures. Electric many ad...

Liquid scintillation spectrometry of 14C in gasoline/ethanol and diesel oil was carried out using QUANTULUS® and straight mixtures of fuel and an organic scintillation cocktail. A linear correlation was found between the concentration of carbon that originates from the bioethanol (biocarbon) and the fuel mixture's 14C activity in the range 0 – 100 % (m/m) bioethanol content. Because of the good...

In this paper we make use of detailed, transaction-level data on automobile purchases and monthly, ZIP-code level data on retail gasoline prices to investigate the effect of fuel prices on four aspects of automobile purchasing in the U.S.: market shares, new car prices, trade-in utilization, and new car inventories. We find statistically and economically significant effects in all four aspects,...

Global discussions on the reduction of Co2 emissions and the increasing interest in alternative energy sources and production technologies have started to concern oil exporting nations. International discussions on projects such as Desert Tec might also have sparked their interest to explore a possible diversification of their energy resource production portfolio. However, extremely low in-coun...

Global economic environment has an important impact on commodity prices. Economic policy uncertainty is indicator of global and factor affecting Through empirical research the index composite index, it found that commodities comprehensive except gold (energy), fuel prices, oil prices fossil fuel, food beverage price industrial base raw materials agricultural metal in addition to agriculture as ...

Non-deforestation fire – i.e., fire that is typically followed by the recovery of natural vegetation – is arguably the most influential disturbance in terrestrial ecosystems, thereby playing a major role in carbon exchanges and affecting many climatic processes. The radiative effect from a given atmospheric CO2 perturbation is the same for fire and fossil fuel combustion. However, major differe...

The efficiency is of paramount importance nowadays due to increasing electrical energy demand, increasing awareness of environmental problems as greenhouse effects and increasing fossil fuel prices. This paper tries to show the different results between the standards for efficiency evaluation and the necessity of harmonization worldwide. Then, it is going to be explained the different standards...

globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. thus the worldwide fast depletion of conventional energy resources and impact of emissions on environm...
