Electricity is a basic necessity that people need to manage day-to-day activities. Science paves the way for continuous development and improvement of different technologies for power generation and distribution worldwide. Science led to the discovery of both the positive and negative effects of power generation on nature and mankind. With the passage of time, experts in the field realized that there are renewable sources of electricity with limited impacts on the environment. The rapid growth of industrialization as well as the increasing reliance of people to manufactured goods and services has significantly contributed to waste problems worldwide. As a result, scientists introduced a number of waste-to-energy (wte) or energy-from-waste (efw) technologies.
An objective of wte technologies is to address global waste management problems, such as the congestion of landfills and difficulties in the proper disposal of garbage or municipal solid waste (MSW). Another is to find a solution to meet an overwhelming increase in demand for electricity worldwide as a result of continuous population growth. The waste management problem and power consumption challenges led to the discovery of wte technologies. Figuratively speaking, wte technologies seemed to have hit two birds with one stone as it helped address two significant global issues with one solution.
Incineration, which is a key process in wte technologies, has been found to also have negative effects on the environment as it leads to the release of potentially harmful gases and other components to the environment. Scientists continuously seek ways on how to limit the negative impacts of incineration to natural resources and humans in line with government mandates and policies. Th...

...find ways on how to better apply processes in wte technologies that would not harm people and the environment while at the same time supporting economic growth and development. As Otto suggested in his report, wte technologies is capable of encouraging people to recycle and segregate waste for proper disposal. It also benefits the environment by limiting the impacts of climate changes through the control of carbon emissions and other harmful components in the atmosphere. Wte technologies are also generally effective in supporting the economy as it helps address the need to meet increasing demands for electricity. This is especially evident with the growing number of wte plants built in several countries such as the U.S. as well as Germany, the Netherlands, Austria, Belgium and Sweden, five European nations with the highest wte usage and recycling rates (Otto, 2013).
The energy which is lost to the environment is used here to recover a wide application based product.
As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.
Boeing took a big step forward with the announcement relating to the joining of the World Environment Center (WEC), “a global non-profit organization that helps companies around the world implement environmentally sustainable business strategies and operations” (WEC, 2005,CRS wire, ¶ 1). With Boeing recognizing the major challenges facing the eco-system of the planet, aggressive but realistic targets for reducing the impact of Boeings operations and lifecycle of their products on the environment. By implementing the aggressive tactics, Boeing improved by 25 percent with solid waste recycling rate and by 2012 the company will increase energy efficiency by cutting greenhouse gas emissions along with comparable goals for hazardous waste reduction.
...ing nuclear waste is a new and unsound technology, but still a solution to the problems of excessive waste. Where in the future, new technologies may allow for the waste to be completely recycled and reused in the reactors to create more energy. With both positives and negatives of nuclear energy, the real question that remains is “if not nuclear, then what else?” (Rutgers’s Felder)
As our population increases, so will our demand for electricity. Air conditioners, computers, televisions, microwaves, and many other appliances have become necessities for Americans. All methods of producing electricity have drawbacks. As the earth becomes warmer, we must look for ways to decrease our use of fossil fuels. There are several ways to produce electricity without releasing air pollution. The most feasible method at this time is nuclear energy. Nuclear energy presents a safe, clean, and inexpensive alternative to other methods of producing electricity. Nuclear waste can either be reprocessed or disposed of safely, provided certain precautions are taken.
Since the end of the World War II, nuclear energy has been one of the most potent forces on the planet. Nuclear powered submarines and aircraft carriers dominate the oceans and nuclear power plants provide nearly 20% of the nation’s power supply (Bayh & Gregg, 2014). All of this nuclear production produces tremendous amounts of nuclear waste. This waste must be disposed of safely, creating a problem for scientists and politicians for decades to come.
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
Energy is what makes the world go around. All of our technologies are designed and developed based on readily available resources, most common of which are fossil fuels. What happens when we run out? The technologies we so heavily rely on for generating food, shelter, and transportation will cease to function. Throughout this article, I will elucidate the importance of developing and implementing alternative energy sources, specifically those that are renewable, into everyday technologies, and the resulting positive and negative consequences that could follow .
Waste incineration units produce a lot of carbon dioxide gas approximately around one third of the greenhouse gasses. It also impacts people’s health as they get exposed to the toxic emissions by breathing in the air or consuming contaminated food and water. Additionally, when the garbage gets burnt by the incinerators they end up as ashes which are then emitted from the chimneys, including the toxic materials and end up in specialist landfill sites for hazardous waste.
The present world with its sustainable resources, environment and way of life became developed. The population growth, consuming almost all the available resources, to meet people’s needs, should be a major concern. The consumption of material and energy around the world which is about to eliminate the available supply, has increased over the last two decades, especially in the built environment. In order to access other reserves of fuel, the more energy will be needed to use.
Today our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed. One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need of energy in today’s current world, exploring different ways of producing power are necessary. The differences and similarities of nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production.
Over the past decades, geologists and scientists alike have determined that the Earth is running out of non-renewable resources, particularly those resources that provide us with energy that fuels our world’s economies, jobs, and most importantly our daily lives. Without this energy, whole countries can collapse, and the human race would struggle to survive. Therefore, it is safe to assume that we as a nation are entirely dependent on energy, or the ability to do work (Gale Science in Context). Consequently, we are now actively searching for more cost efficient and useful forms of energy to replace those we currently use. By doing this we will be helping the earth by reducing carbon emissions and cutting down on air and water pollutants. This may ultimately prolong the life of our planet, and save money and resources while doing so.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
As humanity develops new technology, the magnitude and severity of waste increases. When computers were developed, it widely was believed that the need for paper would be eliminated. On the contrary this was widely proven false and we are now utilizing more paper than ever. Canada is not an exception as the typical Canadian generates an average of three pounds of solid waste each day1. This alone shows what a careless species we have become- using and disposing materials without even considering the damage we are causing. With half a trillion tones of waste around the world, only 25% may be reused for a second or third time and less than 5% can be renewed limitlessly1. These facts are true only in developed countries. Since these traditional waste reduction methods have been proven inefficient, we must endorse new innovative technology to arrive at a solution.
One distinctive element in world stories is that economics was developed within the context of an engineering technology, therefore industrial world require better economic technique and innovation for getting proper benefit from their goods. For this purpose the equipments by which the goods are manufacture are likely to be cent percent efficient or approaches to it. regardless of their nature and purpose.Moreover the globe facing the energy decline and energy along with their resourses is becoming rare and rare in every tick of the clock. Today!.. the burning question is that how the man can save the natural resourses whether it is power,water or even gas. The report deals with the technology by which industrial sector can reduce their energy consumption also their supplier reduce the distribution cost.
