Introduction

In our time, we are used to satisfy our nutritional requirements by simply buying raw or cooked food products at grocery stores or restaurants. Nowadays we can access pretty much any type of food product even if is coming from remote locations at affordable prices. However, there is an extra price to pay: unprecedented amounts of liquid and solid residues continuously accumulate in our soil, air, and water resources as a result of activities associated with food production and consumption. At the consumption end of the food chain, farm products are processed and packaged, distributed and finally eaten. Each of ...

Abstract

Carbon capture is an essential approach for reducing greenhouse gas emissions. Different plants utilize various technologies in reducing carbon dioxide emission. Some of the conventional techniques employed include oxy-fuel, pre, and post-combustion carbon capture. These approaches have a high potential for capturing carbon dioxide. However, their massive initial and implementation costs have been a challenge to plants globally. Additionally, most of them are yet to experience large scale applications. Therefore, it is essential for research and development activities to be conducted. This can ensure a reduction in the cost of production. The carbon capture technologies differ in costs. This ...

Introduction

Coal is a very cheap and abundant provision of energ. In fact, it is the most abundant fuel in the United States; U.S. has the highest coal reserve in the world, with up to 25% of the known world coal present in America and being mined in 26 out of the U.S. 50 states (fe.doe.gov, 2013). However, this abundant energy is seldom used because it is a very dirty energy. According to Hong & Slatick (1994), up to 204.3 pounds of carbon dioxide per million Btu is emitted when coal having 78% carbon content is completely burned to attain a ...

Introduction:

The modern United States economy relies on fossil fuels for up to 82% of the overall energy supply. This energy supports industrial processes, commercial and residential, and transportation purposes. Oil accounts for 34% of the overall energy demand, coal accounts for 39%, natural gas represents 27%, hydropower accounts for 7%, while nuclear energy accounts for 19% (United States Energy Department, 33). However, in terms of net energy consumption, fossil fuels accounted for 67.5% while other energy sources; that is, nuclear and other renewable energy sources, such as hydro-power and wind-energy accounted for 32.5% in 2013 (United States Energy Department, ...

New facts in renewable energy

The U.S. is pushing ahead to try to increase energy production from renewable sources. This is in line with the government strategy of generating a sustainable economy that is no longer dependent on fossil fuels. Recently, much effort has been invested to accelerate and expand technological development in wind, solar, biofuels, and hydropower. For instance, last year the installed wind capacity of the U.S. doubled with respect to the previous year. Also, last year wind energy generation positioned as top one with about 40% of all new facilities. As a result, an important number of new businesses focusing on wind have ...

Compare and Contrast Analysis

The useful features of coal have been discovered by ancient people. However, it is widely used in the modern world. Furthermore, its manufacturing and products from coal are important part of economy strength worldwide. Since the time of ancient Greece and Rome coal did not only lose its significance but it had been increased because many new methods and technologies of coal application have been discovered.

One of the methods of coal processing is combustion. Since antiquity it have been used to produce heat and later electricity. Nowadays, the combustion process is most widely used on the coal of ...

I have nursed a key interest in engineering since my earlier days as a juvenile. As an apprentice of my father, a petroleum engineer, I was fascinated by his exposes on advances in technology, especially in the petroleum engineering field. When narrating his stories, he would always attach a societal perspective to the many inventions and innovations he told of. According to him, advancements in technology were solutions to problems that dogged the society. He painted engineers as supremely endearing people who had the interests of the society at heart. As a curious child growing up, I was consumed with the notion of making ...
