Offering the world's becoming inhabitants with its expanding calls for for strength is an important problem for technological know-how, enterprise and society alike. power will be generated from many resources, yet no longer all resources are appropriate for each software. a lot of present day know-how has been equipped on sturdy, liquid and gaseous fuels derived from fossil resources. even though, the provision of those is finite and their combustion produces carbon dioxide, one of many gases liable for worldwide warming. for this reason, replacement resources of strength are required that are renewable, sustainable and carbon neutral.This textbook explores the creation of biofuels as possible choices to fossil fuels, targeting the technological concerns that have to be addressed for any new gas resource. every one kind of biofuel presently in creation is taken into account intimately, overlaying the advantages and issues of construction and use and the possibility of organic fabric to supply enough power for the world's inhabitants - the rules on which destiny gas improvement are established.

One of the fuels tested in an enzyme-based fuel cell is glycerol, one of the by-products of biodiesel production. , 2007). Battery electric vehicles The electric vehicle is ideal for use in cities as it emits no fumes and can be integrated into city-wide traffic systems where travelling distances are short. The electricity needed to charge the battery can be generated from renewable sources, which leads to a 48 Chapter 3 considerable reduction in carbon dioxide emissions. However, for long journeys battery technology and electricity storage is the key point.

A global carbon pricing regime based on carbon taxes and permits. Global satellite monitoring of greenhouse gas emissions. Compensating developing countries for preserving rainforests. Creation of a global market for responsible biofuels. , 2006), but it is unrealistic to see temperate regions becoming self-sufficient in biofuels. It is far more expedient to open up the Mitigation of Global Warming 43 world market and to encourage trade in biofuels, both to accelerate the utilization of biofuels as a defence against global warming, and to encourage industrial development of tropical countries as the world’s supplier of biofuels: 5.

Replacing coal with natural gas also reduces sulfur emissions as natural gas contains little sulfur. Sulfur compounds can be removed from the flue gas and the most common is the limestone/gypsum method, where the flue gas is treated with calcium carbonate slurry (limestone). The calcium carbonate reacts with sulfur dioxide to yield insoluble calcium sulfate (gypsum) which precipitates and can be removed. ● ● Photochemical smog The burning of fossil fuels also produces particulates, soot and black smoke from vehicles and power stations.
