7. Coal tar- It is achieved as a byproduct in the process of making coke. Though its color is the same as coke, tar is a highly viscous liquid. It also has an awfully unpleasant smell. Coal tar is broadly used to manufacture paints, perfumes, synthetic dyes, photographic material, drugs and explosives.
Lauren Ryan Professor Buckingham GEOG 123, Section AN 8 December 2014 Costco: A Cut Above the Rest Introduction Costco Wholesale Corporation, in terms of their business practices and ethical standards, stands out above the rest. From the beginning, the owners, James Sinegal and Jeffrey Brotman, decided they wanted to avoid the corrupt practices associated with globalizing. No company is completely free from or unaffected by globalization; but Costco has done a pretty good job being fair in all of its transactions and affairs. From when it started to where it globalized, Costco’s process for globalizing and the reasoning behind it have made them not only a great company but also an incredibly successful company. Furthermore, many company’s
This energy can reach many houses at once without any problems. Coal is effective unlike solar energy which has to be installed on top of the roofs of the houses and not one common place for all the solar panels which can be a disadvantage as not all houses will have them or the amount of energy distributed depending on the location of the houses of which some can be under the mountain which creates shade and have less sun coming out. Equal distribution of power depending on when it is used is an advantage to coal energy using households and still continues to be effective. . [Source: Coal
Boli Monger Danny Bellinger English 1101, 60499 July 11, 2017 Compare and Contrast Solar energy is better than Coal In today’s world energy is one of the essential things that we all need in our daily life. We human being use energy for everything from doing simple work at home to doing big work, like sending astronauts into space. There are various sources of energy, among them, the healthiest and environmentally safe is solar energy. Solar energy is defined as a renewable form of power or heat which is naturally produced by the sun light. According to the Energy Information Administration (solar vs coal 2), 15 years ago, the electricity industry made a huge shift towards renewable sources of energy because of its cheap availability and increasing popularity.
Introduction Coal is a variety of solid, combustible and organic sedimentary rocks formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years (IEA, 2017). Around the world, requirements for energy and electricity are met by fossil fuels amongst which coal is the most abundant and broadly distributed. It is the most common fuel choice because it is a secure and low cost energy source and is relatively easy to mine, ship, and store. Coal is the second source of primary energy after oil and is mostly used for power generation. Over 40% of worldwide electricity is produced from coal (IEA, 2017).
1. INTRODUCTION Coal gasification is a process for producing a mixture gas consisting mainly of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapor (H2O) -from coal and water, air and / or oxygen. This gas mixture is called synthesis gas. Earlier, coal was gasified using old technology to produce coal gas (also known as the "town gas"), which is a fuel gas used previously for municipal lighting and heating before the advent of the commercial scale production of natural gas. In current practices, instances of large coal gasification is used to generate electricity, as in the combined cycle with an integrated gasification for production of chemical feed stocks or for the production of gas natural synthesis.
Coal has traditionally dominated the energy supply sector in South Africa, from as early as 1880 when coal from the Vereeniging area was supplied to the Kimberley diamond fields. Presently, about 77% of our country 's primary energy needs are provided by coal. All of us want an affordable and reliable energy source which we can only get by using coal energy. Although using coal energy is significant for us and living without it would become impossible, we should always open our minds to the damage the continuous use of coal energy will eventually bring to us and to our

Costco’s intensive growth strategy is to remain strong despite of the tough competition with Wal-Mart and local players such as E-Mart, Carrefour, and Sam’s Club. Twelve years ago, 1994, Costco entered a joint venture Shinsegae Department Store for learning. Costco learned Korean retailing with Korean customers; Shinsegae learned wholesale discount business for profit. Nevertheless, two companies had divided apart by Costco buying out most of Shinsegae interests for $94 million. Later Shinsegae Department Store, now E-Mart in Korea, bought Wal-Mart in Korea for approximately $825 million.
