Fossil fuel consumption global

The EGA considers fossil fuel consumption, global warming potential, summer smog potential, acidification, eutrophication, carcinogenic risk, and human toxicity. The EGA did not consider waste generation or water consumption. To provide a more complete EGA, the waste generation and water consumption were calculated for each plastic based on reference sources. 

Coal forms about 60% of the global fossil fuel resources that are relatively evenly distributed around the world in more than 90 countries. The relative share of the coal consumption had a peak of 70% around 1900, but since then the relative importance has been on decline. Nowadays approximately % of the global fossil fuel consumption is by solids, from which 60 % is used for power generation. 

Table 7.7 illustrates the rapid increase of global fossil fuel consumption from the data of the World Resources Institute for 1950-2003. We shall now consider more detailed statistical data for different kinds of fossil fuel and energy resources in general, with emphasis on extremely non-uniform distributions of energy consumption for different countries (Table 7.8). 

We now synthesize much of the knowledge outlined in previous sections on the global budget of C02. Firstly, the relative sizes of the natural reservoirs are considered and then the natural flows between them, followed by how anthropogenic C02 partitions between the boxes. Finally, likely future levels of atmospheric C02 are discussed in terms of possible scenarios of fossil fuel consumption. 

In the past few years, application of improved measurements and models suggests a robust partitioning of CO, emissions from fossil fuel consumption and land use about one-third remains in the atmosphere, one-third is reassimilated by land surfaces, and one-third is absorbed by the oceans (Keeling el ah, 1996). The terrestrial component of the sink has special political interest, because it is that part of the global carbon which can most directly be managed. If we were able to change the large fluxes of assimilation and respiration, as they were summarized by Schimel... 

Given the global impact of fossil fuel consumption in terms of particulates and atmospheric pollution, many international organizations are taking an active interest in hioenergy technology and have released a number of statements regarding the adoption of... 

Natural gas consists usually of a mixture of 80-95 % (by volume) methane (CH4) and the remaining 5-20 % heavier hydrocarbons, mainly ethane (C2H6) and propane (C3H6), and varying amounts of carbon dioxide and nitrogen. Current global consumption of natural gas amounts to about 10 g of carbon per year, which is 20 % of the total fossil fuel consumption rate [29]. The current atmospheric content of ethane is equal to about 6 x 10 g of carbon, based on observations indicating amounts of 1 ppbv (1 ppbv = 10 by volume) in the Southern...
