Energy world-wide

With shortages of fossil energy and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Currently, a heavy focus is on biofuels made from crops, crop residues and wood. Though it may seem beneficial to use renewable plant materials for biofuel, their use raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources.

The increasing demand for energy worldwide, together with the depletion of crude oil reserves, environmental threats due to greenhouse gas emissions and new national and international legislation, is resulting in the imperative for petroleum-derived fuels to be complemented or substituted by biofuels. Such an alternative, renewable, biodegradable and nontoxic biofuel is biodiesel. The book “Biodiesel: Feedstocks and Processing Technologies” is intended to provide a professional look on the recent achievements and emerging trends in biodiesel production.

The empirical results indicate that the state owned oil companies underperform the private oil companies and a political preference for a state ownership oil companies will come at an economic cost. Even though the results seem to suggest privatization for KNOC, there are some empirical evidences that the existence of state ownership is still important for the stability of the domestic energy market.

Solar energy technology is very important tool which can lowers worldwide carbon emissions. The present study was conducted in Jaipur district of Rajasthan. There are total sixteen tehsils in Jaipur district of Rajasthan, out of which, two tehsils namely Chomu and Amber were selected on the basis of maximum number of installed of solar pump. Ten villages from each selected tehsils were selected randomly by using proportional allocation technique. One hundred twenty (120) farmers were selected from twenty selected village by using proportional allocation technique.

The fossil fuels that are principally used to provide energy today are in limited quantity, they are diminishing at an alarming rate, and their worldwide supplies will eventually be exhausted. Fossil fuels provide approximately 60 percent of the world’s global electric power. Carbon dioxide levels in the atmosphere will continue to rise unless other cleaner sources of energy are explored. Biomass has the potential to become one of the major global primary energy source in the years to come.

The use of biodiesel worldwide is becoming increasingly important, because of the widespread shortage of oil resources, which has raised the prices of fossil fuels. This biofuel also offers an opportunity to meet the energy demands with less impact to the environment due its renewable characteristics. This book entitled "Biodiesel – Quality, Emissions and By-Products" comprises 20 chapters and covers topics related to biodiesel quality, performance of combustion engines that use biodiesel, and the emissions they generate.

The sustainability and prosperity of the ancient civilizations of China, Egypt, Babylonia, Phoenicia, Persia and Roma were based on the extensive use of water for human consumption, crop irrigation, canal navigation and energy generation. Today, the worldwide scarcity of water and clean energy constitutes a central and critical problem for the whole humankind. This situation is aggravated as industrial, agricultural and municipal effl uents reach the water bodies, or the coastal seawater that is used as feed for desalination plants.

As shown in Table 2, the area of agricultural land worldwide is larger than that of forests (FAOSTAT Resources 2009). Furthermore, non-wood fibres usually have high annual biomass yields per hectare which are equal or superior to that of woods (Pierce 1991). Approximately 30% of the forest area is used primarily for the production of wood. An additional 24% of the forest area is designated for multiple uses, which also includes the production of wood in most cases (FAO 2010).

The main objective of this work is to develop an economically viable process for producing papermaking fibres of adequate quality and generating energy from wheat straw. Wheat straw was selected as the raw material since wheat is cultivated and available worldwide (Curtis 2002) and only a minor part of the straw is used for energy production or animal feed. One of the primary aims in this work is to find ways to store the raw material chemically between the harvesting periods and examine the effects on pulping and pulp properties (Paper IV). In addition, the aim of this work is...
