Different energy conversion technologies have their applications, but no single option does it all. Wind, solar, and hydro options don’t use any fuel, so shouldn’t we just rely on these technologies? Wind power is best sited where the duration/velocity makes sense, away from migration pathways, and away from neighbours who would object to noise and fluttering shadows. It will likely require 100 per cent back-up or additional energy storage systems, and new longer transmission lines to load centres are often required. There are similar requirements for solar power, just substitute lumens for velocity.

...Hydraulic fracturing, otherwise known as fracking, is a 60 year old practice of pumping high pressure water into shale rock thousands of feet below the earth’s surface. The pressurized water is pumped through cement encased pipes at pressures reaching 9000 pounds per square inch. The treated water is forced into small cracks in the gas-rich shale rock, resulting in the breaking of the rock and the release of natural gas that would otherwise be unobtainable. Hydraulic fracturing is a safe, economically efficient way to drill for natural gas, create jobs, and lessen America’s dependency on foreign oil. Safety is always an important factor when considering new methods for obtaining raw energy sources such as coal, oil, and natural and shale gas. The process of fracking can be considered relatively safe when compared to oil drilling and mining. For example, in 2010 an offshore drilling station suffered a malfunction in a blow back valve that caused a massive explosion killing 11 people and spilling an estimated 200 million gallons of oil into the Gulf of Mexico (Center for Biological Diversity, 2011). While the cost of lost lives is immeasurable, the costs of lost profits from the spilling oil, and the clean-up, are astronomical. The consequences of oil spills are not only immediate, but can also be felt for years after. Similar to the BP oil spill, in 1989 the Exxon Valdez ship ran aground spilling an estimated 750 thousand barrels of crude oil, an amount that equals almost...

In the 1700s, people found that it would heat cleaner and hotter than wood charcoal. The Industrial Revolutions overwhelming need for energy to run the new technologies providing the real opportunity for coal to dominant as a worldwide supplier of energy. (A brief history of coal use). As other sources of energy was discovered the use of coal diminished. However, 4 decades ago it became popular again as an energy source. The 1970’s brought about an oil crisis that showed industrialized countries that any disruption in the petroleum supply line would send a shockwave through energy production. (Morse, 2012).

...Demand And Supply Of Crude Oil 10/10/2009 Introduction Crude oil is a naturally occurring substance (i.e., “Fossil Fuel”, formed from organic remains over a period of millions of years) found in certain rock formations in the earth. It is a dark, sticky liquid which, scientifically speaking, is classified as a hydrocarbon. This means, it is a compound containing carbon and hydrogen, with or without non-metallic elements such as oxygen and sulfur. Crude oil is highly flammable and can be burned to create energy. Derivatives from crude oil make an excellent fuel. Uses Different types of oil that are obtained from crude oil are as mentioned below: 1. Ethane and other short-chain alkanes 2. Diesel fuel (petro diesel) 3. Fuel oils 4. Gasoline (Petrol) 5. Jet fuel 6. Kerosene 7. Liquefied petroleum gas (LPG) 8. Natural gas Certain types of resultant hydrocarbons when mixed with other non-hydrocarbons, create other products like: 1. Alkenes (olefins), which can be manufactured into plastics or other compounds. 2. Lubricants (produces light machine oils, motor oils, and greases, adding viscosity stabilizers as required). 3. Wax, used in the packaging of frozen foods, among others. 4. Sulfur or Sulfuric acid. These are useful industrial materials. Sulfuric acid is usually prepared as the acid precursor oleum, a byproduct of sulfur removal from fuels. 5. Bulk tar. 6. Asphalt 7. Petroleum coke, used...

...Energy Chapter 13 Section 13-1 WHAT IS NET ENERGY AND WHY IS IT IMPORTANT? Basic science: Net energy is the only energy that really counts • The usable amount of high-quality energy available from a given quantity of an energy resource is its net energy yield: the total amount of useful energy available from an energy resource minus the energy needed to make it available to consumers. • We can express net energy as the ratio of energy produced to the energy used to produce it. As the ratio increases, the net energy also rises. When the ratio is less than 1, there is a net energy loss. Net energy ratios for various energy systems over their estimated lifetimes differ widely Fig. 13-2a, p. 301 Fig. 13-2b, p. 301 Fig. 13-2c, p. 301 Fig. 13-2d, p. 301 Energy resources with low or negative net energy need help to compete in the marketplace • Any energy resource with a low or negative net energy ratio cannot compete in the open marketplace with other energy alternatives with higher net energy ratios unless it receives financial support from the government (taxpayers) or other outside sources of funding. – For example, the low net energy yield for the nuclear power fuel cycle is one reason why many governments throughout the world must heavily support nuclear power financially to make it available to consumers at an affordable price.

Assistant Professor Fundamentals of energy and its impact on society and the environment. What is energy? • Energy :defined as the ability or capacity to do work. Energy is measured in BTU (British Thermal Unit) or Joule • According to Max Planck, energy is defined as the ability of a system to cause external action. • The term energy carrier – thus a carrier of the above defined energy – is a substance that could be used to produce useful energy, either directly or by one or several conversion processes • In this respect the following forms of energy are distinguished: mechanical energy (i.e. potential or kinetic energy), thermal, electric and chemical energy, nuclear energy and solar energy etc. Why Energy is needed ? • Think about how you use energy every day. You wake up to an alarm clock. You take a shower with water warmed by a hot water heater. You listen to music on the radio as you dress , u eat breakfast….. And so on……. • Food items, medicines, groceries, the accessories which we use, Cosmetics, electronic appliances, lighting, heating cooling, • Everything needs energy in direct or indirect way Why Energy is needed ?

...Reproduced with permission from Energy for Sustainable Development Articles Synthetic fuel production by indirect coal liquefaction Eric D. Larson Princeton Environmental Institute, Princeton University Guyot Hall, Washington Road, Princeton, NJ 08544-1003, USA E-mail: elarson@princeton.edu Ren Tingjin Department of Thermal Engineering, Tsinghua University, 100084 Beijing, China This paper reports detailed process designs and cost assessments for production of clean liquid fuels (methanol and dimethyl ether) by indirect coal liquefaction (ICL). Gasification of coal produces a synthesis gas that can be converted to liquid fuel by synthesis over appropriate catalysts. Recycling of unconverted synthesis gas back to the synthesis reactor enables a larger fraction of the coal energy to be converted to liquid fuel. Passing synthesis gas once over the synthesis catalyst, with unconverted synthesis gas used to generate electricity in a gas turbine combined cycle, leads to less liquid fuel production, but provides for a significant second revenue stream from sale of electricity. Recently-developed liquid-phase synthesis reactors are especially attractive for ‘‘oncethrough’’ processing. Both ‘‘recycle’’ and ‘‘once-through’’ plant configurations are evaluated in this paper. Because synthesis catalysts are poisoned by sulfur, essentially all sulfur must be removed upstream. Upstream removal of CO2 from the synthesis gas is also desirable to maximize synthesis productivity, and it provides...

...CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF STUDY Removal of heavy metals such as cadmium, lead, nickel, chromium and copper from aqueous solution is necessary because of the hazardous effect it does on the environment ,thereby making environmental protection important, however waste solutions containing heavy metal elements need treatment systems that can remove these contaminants effectively (Harvey and Chantawong, 2001). Frequent appearance of these metals in waste streams from many industries, including electroplating, metal finishing, metallurgical, tannery, chemical manufacturing, mining and battery manufacturing. This problem has received considerable attention in recent years, primarily due to the concern that those heavy metals in waste streams can be readily adsorbed by marine animals and directly enter the human food chain, thus presenting a high health risk to consumers (Lin et al., 2000). A number of technologies for treating contaminated effluents have been developed over the years. The most important of these techniques include chemical precipitation, filtration, ion- exchange, reverse osmosis and membrane systems. However, all these techniques have their inherent advantages and limitations in application. In the last few years, adsorption has been shown to be an alternative method for removing dissolved metal ions from liquid wastes (Bayat, 2002). The removal of heavy metal ions from industrial wastes using different adsorbents is currently...
