Introduction (background) http://renewable-solarenergy.com/non-renewable-energy-sources.html What was used before to generate energy? * Fossil fuels(The term ‘fossil fuel’ refers to fuels such as coal, oil and natural gas. ) * Where do it come from? How can it be used? It can be used to produce electricity, heating, cooking, transportation and manufacturing. 85% of the energy used in the industrial processes is form the non-renewable type of energy. * Transportation?... http://renewablegreen.net/?p=124 What limitations or disadvantages does non-renewable energy have? * However, after never-ending mining and ‘drill baby drill,’ we realized that there is was limitation to how much we can use them. Because one day, the mines will be empty and drilling pipes would dry out. Over the years, their demand has been far outstripping their availability. * Pollution created (air, water) => Global warming and greenhouse effect * Increasing oil price (because of limited resources) And with demand overpowering supply, prices will continue to rise dramatically. Combustion of fossil fuels emits harmful gases like sulfur dioxide (causing acid rain) and carbon monoxide (contributing to greenhouse effect). Due to the adverse affects, the globe is heating up and the polar ice caps are melting faster. A need to shift to substitutes (renewable energy) 1. Produce harmful green house gases which contribute global warming...

Without some form of energy we would not have the essentials such as: refrigerators, lights, cars, etc... Now we are faced with the decision, whether or not we should continue using non-reusable energy or should we invest in renewable energy. Non-renewable sources of energy productions come from the ground and cannot be used again and again. These sources are from fossil fuels such as coal, oil, and natural gas. The advantages of non-renewable energy are; naturally found in the earth, easy to mine, and cheap, which make it available and affordable. The disadvantage from using this energy sources are; one day we will deplete these natural resources and they take about a hundred million years to replenish. Unfortunately, at the rate we consume these fuels; there are not enough resources to sustain our future energy demands. Furthermore, this energy source is causing serious damage to our environment...

... “Energyconservation refers to efforts made to reduce energy consumption. Energyconservation can be achieved through increased efficient energy use, inconjunction with decreased energy consumption and/or reduced consumption fromconventional energy sources” ("Energy conservation," 2011). The twotypes of energy are renewable and nonrenewable. Renewable energy sources areconstantly renewed or restored and include wind (wind power), water(hydropower), sun (solar), vegetation (biomass), and internal heat of the earth(geothermal). On the other hand, nonrenewable energy sources are naturalresources that cannot be replenished. Fossil fuels such as oil, gas, and coalare the most commonly used types of non-renewable energy. However,non-renewable energy sources are being depleted at a rapid rate. In fact, (dueto this depletion) there may not be enough non-renewable energy sources forfuture generations. Additionally, (in this paper) I will discuss methods toconserve energy, save money, and help the environment as well. Because fossil fuels (such as oil,gas, and coal) are the most commonly used types of non-renewable energy, I willfocus on these types of non-renewable energy sources. “World energy consumptionhas increased every year since 1982, with most of the increase occurring indeveloping countries” (Berg, & Hager, 2007). “Additional energy demands inhighly developed nations may be met by increasing the energy efficiency ofthings like appliances, automobiles, and home insulation”...

...Frackopoly by Wenonah Hauter is a nonfiction environmentalist novel about the history of energy sources in the United States. This book shows how the influences in politics took control of our energy and pushed it towards fossil fuels and other nonrenewable resources. The United States spends $37.5 billion dollars annually on the exploration and production of fossil fuels. (Kretzmann, 2015) Fossil fuels have a very heavy use in today’s society, being used for heating and fueling our everyday lives. Only 12% of the energy research budget was spent on trying to expand the renewable side of energy and 10% on efficient use of energy. (Hauter, 2016) Most of the federal money being spent on energy is going towards increasing our oil and gas companies....

...Michael Allen October 16, 2012 According to the Iowa Department of Natural Resources, the fuels Iowans use fall into two main categories: nonrenewable in the form of fossil (coal, petroleum, and natural gas) and nuclear fuels and renewable energy resources (water for hydroelectricity, biomass, wind, and solar). The use of energy is divided into four sectors: Commercial usage is 15%, Residential usage is 22%, Transportation 22%, Industrial 41% Energy, in all its varied forms, is an essential part of every aspect of our lives. It’s the foundation for our economy and our lifestyles. In my home, most of my energy dollars goes to heat my home in the winter and make hot water. During the summer months the dollars spent on heating the home is switched to cooling the home. A small percentage goes to powering appliances and electronics. We use natural gas as a single heat source and all of my appliances are electric including the stove, washer, and dryer. I am very conscious about energy conservation in the home. We adjust the thermostat by lowering it in the winter to 68 and raising it in the summer to 78 by day and 60 and 82 during the evening. We change the furnace filter every 3 months and unplug TV’s, cell phone charges, computers, electronics, toaster, microwave, radios when we are not in the home. All lighting sources in the home are now equipped with compact fluorescent lamps vs the traditional light bulbs. Using the fluorescent lamps, we even use a lower...

...greater than the capacity of available resources to provide those wants. 3 Parts: 1. People want it 2. There is a limited amount of it 3. It has more than one productive use Scarcity Scarcity vs. Abundance – people see many signs of abundance (e.g. cell phones, iPods) and also see resources wasted daily (e.g. water and food). However, as long as resources are limited and people’s wants are unlimited, scarcity (in the economic sense) will exist. Scarcity In economic reasoning, scarcity is a relative concept, not an absolute one. Scarcity does not mean “not plentiful.” In economics, something is scarce when it has more than one valuable use. = & Opportunity Cost Opportunity cost is what you give up to obtain something else, the second-best alternative. However, what you must give up is not money – it is whatever good or service you would have spent the money on as your next favorite choice. Goods v.

It addresses two hypotheses; (1) life, since its inception, has greatly affected the planetary environment and (2) life has altered Earth’s environment in ways that have allowed life to persist. Do you agree with these two hypotheses? Why or why not? Energy and Food Supplies. The underlying theme of this course is energy. As a whole, the global society needs to find ways to reduce our energy consumption. The food pyramid is a prime example of energy transfer within individual ecosystems and the biosphere. As you increase the trophic levels, a greater amount of energy is lost. Some environmentalists argue that humans should eat a vegetarian diet in order to conserve energy. What are some of the pros and cons of this action? Consider the impact to the agricultural industry? How low on the food chain do you eat? Would you consider eating lower? Model Ecosystems.

...1 Chapter 16 Externalities Consumers and producers are internal to a transaction. Consumers receive a benefit from the goods they purchase, while producers pay the costs of production. An externality (sometimes called a spillover) is a cost or benefit that goes to someone external to a transaction. Pollution is a negative (cost) externality. Education and research create a positive externality. Externalities can result from consumption or production. 2 An Example: Suppose that the costs of raising livestock are mostly borne by the rancher, but there is a spillover cost. Streams nearby get polluted, and this affects people (and other species) who use the stream as well as spinach farmers who also use the water for irrigation. Ranchers will consider their own costs of production, but the costs to others could be greater than the surplus from cattle production. 1 3 Negative Externalities • If there is an external cost from production, the Marginal Social Cost is higher than the producer’s Marginal Cost (competitive Supply). • The competitive equilibrium will produce more than the optimal quantity for Society. • If there is an external cost to consumption, the Marginal Social Value is less than Demand. 4 Positive Externalities • If there is an external benefit from consumption, the Marginal Social Benefit is higher than consumer Demand. • The competitive equilibrium will produce less than the optimal quantity for Society. • If there is an external benefit...

... The U.S. economy is dependent upon nonrenewable fossil fuels (oil, natural gas and coal) to thrive. Because of this, it faces big problems due to that economy failing and an environment that is being devastated by carbon emissions. This dependency has to stop. Consumer demands for greener products and services are putting increased pressure on businesses and the federal government to be the catalyst in ensuring the change efforts succeed and at the same time help to grow the economy. The environment has become a scarce resource and with that scarcity come impacts to the economy of the United States. According to Van Jones, founder and president of Green for All, two of the biggest problems facing the United States are “a failing economy and a devastated environment.” (Van Jones, 2008, pg 5). Focusing on how the environment is impacting the economy is key to getting on the right track toward solving these problems. The U.S. economy is dependent upon fossil fuels (oil, natural gas and coal) to thrive. All of these fossil fuels, unfortunately, are nonrenewable resources that are in high demand by the American people. When you apply the laws of supply and demand into the equation, scarcity of resources with increasing demand means higher prices to consumers. Americans have experienced the higher prices firsthand at the gas pump. In addition to the costs associated with the high demand for these nonrenewable resources there is also concern for what they are doing...

...Capstone Assignment International Forces Paper International Forces EXECUTIVE SUMMARY Companies are under pressure to make profit that are satisfactory to the shareholders. The pressure to make profit prompts most companies to go global and look for new markets outside the country. When a company goes global, it becomes a multinational or international company because it has operations in more than one country. Multinational companies usually have increase profits and sales than their domestic counterpart. International companies encounter different kinds of international environmental forces that impact their business. Most of the international environmental forces are; Cultural, Physical, Political, Intellectual, Legal, International Monetary system and Financial forces. These force are very important for a company to consider carefully before it ventures into any country for business. International companies that did not manage these international environmental forces properly have gone out of business. Most Multinationals in recent times have dedicated departments that handle these forces. This capstone project will discuss the impact of international environmental forces on Shell Petroleum Development Company. Shell is a Royal Dutch company that has many locations globally, and is one of the major oil companies in the world. Most of its international environmental forces issues will mainly focus on Nigeria, where the company has been operating since 1937 and also...
