Energy Consumption Spectrum And Its Impact On The Global Warming Issue

2909 Words12 Pages
The chapter provides a brief outline on World’s energy consumption spectrum and its impact on the global warming issue. An overview of absorption and adsorption technologies for post-combustion CO2 capture from coal-fired power plants is discussed. The advantages of adsorption over other absorption and subsequently the importance of amine tethered mesoporous silica adsorbents for CO2 capture is discussed. Thereafter, the chapter presents the outline of objectives of the doctoral work followed by organization of the thesis. 1.1. Introduction In the recent years, World’s energy consumption has been increasing at a rapid rate due to economic development and population growth. The International Energy Outlook report released in July 2013 (IEO2013) projects that there will be 56% rise in the world energy consumption by 2040 (ref). It has been projected that total world energy use rises from 524 quadrillion British thermal units (Btu) in 2010 to 630 quadrillion Btu in 2020 and to 820 quadrillion Btu in 2040, which corresponds to an increase of 16% and 36% respectively (Figure 1.1). It has been predicted that much of the growth in energy consumption may occur in countries that are not included in Organization for Economic Cooperation and Development (OECD) (ref). At present, there prevails huge variation in the economic performance of various countries world-wide. For OECD countries, the pace of economic growth varies but is relatively slow when compared to emerging
