  • When fuel cells were first suggested and discussed back in the nineteenth century, it was firmly hoped that distinctly higher efficiencies could be attained with them when converting the chemical energy of natural fuels to electric power. Now that the world supply of fossil fuels is seen to be finite, this hope turns into a need, into a question of maintaining advanced standards of life.

  • Hydrogen and fuel cells are seen by many as key solutions for the 21st century, enabling clean efficient production of power and heat from a range of primary energy sources. The High Level Group for Hydrogen and Fuel Cells Technologies was initiated in October 2002 by the Vice President of the European Commission, Loyola de Palacio, Commissioner for Energy and Transport, and Mr Philippe Busquin, Commissioner for Research.

  • Renewable energy sources such as solar power, wind power, hydroelectric power, geothermal power, and so on have attracted much attention as alternatives to fossil fuels, because toxins and pollutants are not produced by these sources. For this reason, these energy sources have come to be known as clean energy.

  • Although there were many books and papers that deal with gasification, there has been only a few practical book explaining the technology in actual application and the market situation in reality. Gasification is a key technology in converting coal, biomass, and wastes to useful high-value products. Until renewable energy can provide affordable energy hopefully by the year 2030, gasification can bridge the transition period by providing the clean liquid fuels, gas, and chemicals from the low grade feedstock....

  • This book is concerned with the subject of Wind Energy, as a source of clean and renewable and free for all. The need for this type of book is very well documented, the current consumption of energy is unsustainable and humans have to change their habits and or utilise this source, but there is so much work before we can rely completely on renewable energy. This book aims to describe the fundamentals of wind energy and the pertinent parameters that control the amount of energy available from a given wind turbine....

  • Desai et al. (2004) provide a meta-analysis of health effects from household solid fuel air pollution. Health effects were categorized by level of evidence from the research literature. Relative risk ratios associated with solid fuel use, relative to clean fuels such as LPG, were derived for each health outcome (table 3.1). 11 The national and global mortality and DALY estimates presented by WHO (2007) reflect the relative risk ratios in Desai et al, limiting the health effects to ALRI in children u5, and COPD and lung cancer in adult women and men. ALRI...

  • Ezzati and Kammen (2001, 2002) present indoor PM concentration measurements also for several types of charcoal stoves. PM concentrations are found to be substantially lower than concentrations from fuel wood stoves. Charcoal is often considered by households as an intermediate fuel on the energy ladder. While it certainly is not considered a clean fuel, it is often a preferred choice in many urban areas whenever available instead of fuel wood, before households can afford LPG or other clean alternatives.

  • If your car doesn’t start in the morning, you should check three things first: the battery, the fuel level and the spark plugs. It is easy to repair three faults. If the battery is flat, you should recharge it. If it doesn’t work, you should replace it. If the petrol tank is empty, fill it up. If the spark plugs are dirty, clean them, and if the gap in a spark plug is too narrow or too wide, adjust it to the correct width. Read the text and match these pictures in Figure 7.1 with words from the passage: If your car still doesn’t start, the petrol pump may...

  • Hydrogen and synthesis gas (syngas) are indispensable in chemical, oil, and energy industries. They are important building blocks and serve as feedstocks for the production of chemicals such as ammonia and methanol. Hydrogen is used in petroleum refi neries to produce clean transportation fuels, and its consumption is expected to increase dramatically in the near future as refi ners need to process increasingly heavier and sour crudes.

  • Ethanol use has also been boosted by the U.S. Clean Air Act and its various progressions. Originally, the Clean Air Act required wintertime use of oxygenated fuels in some urban areas to ensure more complete burning of petroleum fuels. Since ethanol contains 35 percent oxygen, this requirement of the act could be met by using an ethanol-containing blend. The current Energy Act eliminates the need for oxygenates per se in RFG, but it speci- fies the minimum amount of renewable fuels to be added to gasoline....

  • The contributions in this book present an overview of utting edge research on natural gas which is a vital component of world’s supply of energy. Natural gas is combustible mixture of hydrocarbon gases, primarily methane but also heavier gaseous hydrocarbons such as ethane, propane and butane. Unlike other fossil fuels, natural gas is clean burning and emits lower levels of potentially harmful by-products into the air. Therefore, it is considered as one of the cleanest, safest, and most useful of all energy sources applied in variety of residential, commercial and industrial fields....

  • The problems associated with the frenetic combustion of fossil fuels are many: pollution, global warming, and foreseeable exhaustion of resources, among others. Although difficult to estimate, the costs associated with these problems are huge and indirect,8 and may be financial, human, or both. Costs induced by pollution include, but are not limited to, health expenses, the cost of replanting forests devastated by acid rain, and the cost of cleaning and fixing monuments corroded by acid rain. Health expenses probably represent the largest share of these costs, especially in developed...

  • Clean air is a basic requirement of life. The quality of air inside homes, offices, schools, day care centres, public buildings, health care facilities or other private and public buildings where people spend a large part of their life is an essential determinant of healthy life and people’s well-being. Hazardous substances emit- ted from buildings, construction materials and indoor equipment or due to hu- man activities indoors, such as combustion of fuels for cooking or heating, lead to a broad range of health problems and may even be fatal....

  • Work and Employment. Women play an extremely important role in all dimensions of agricultural production. In certain regions, women's time input equals men's, but in other regions traditions restrict their work to the household where they are involved in crop processing (threshing, cleaning, drying, preserving) and also are in charge of most of the household-based activities (water and fuel collection, cooking, cleaning, sewing, tailoring, weaving, and child rearing). Women play an increasingly important role in opium production, livestock production and processing of dairy products.
