Assignment 1: Explain How Energy Evolved Into A Consumable Good
WK 1-DQ1:
Explain how energy evolved over time into a consumable good. Does it still satisfy the original need for which it was created? Why or why not? How have our basic needs for energy changed?

According to Aubrecht (2006), the daily energy use per person has increased from 2,000 kcals when humans were just hunters to 244,526 kcals in 2000. From the beginning of the human race, we have used energy; First by setting wood and other materials on fire, using animals to assist in daily tasks, to using machinery, to finally evolving to the massive use of energy today. Today energy is still needed to cook our food and make our daily lives easier thus satisfying the original need. Although energy is still necessary, I believe humans use too much

WK2-DQ2:
Explain what is meant by base load, intermediate load, and peak load. Why are these concepts important to understanding the production of electricity and energy management? How do these relate to the end users of the product?

According to Aubrecht, base load is the basic amount of electricity that is always required. Base load is generated by the utilities large facilities. Intermediate load is the amount of electricity that slowly cycles on and off. Peak load is the time in which demand for electricity is the greatest. Peak load is usually only a few hours a day. Utilities meet peak load demand by using additional generators that can be stated quickly.

Electricity cannot be easily stored. Therefore, demand has to be anticipated by the utility company. Season and time of day are the predominate drivers of consumption. Enough electricity needs to be supplied to meet demand on the hottest day of summer. Maintaining a reliable electric system without interrupting power to the consumer cannot be accomplished without the balance of supply and demand.

    Energy is defined as the ability to do work, such as propel the body forward by taking a step (motion). Energy and its ability to do work are measured in joules: power (watts) x time (seconds) and work joules = force (newtons) x distance (Trefil et al, 2010). Energy exists in many forms; kinetic (motion or movement), potential (stored), thermal/heat (atoms and molecules), wave and mass (Trefil et al, 2010) to name a few. Energy is interchangeable, thus it can be changed from one form to another. Where might all of this energy come from? All living systems and/or organisms are sustained through a process call photosynthesis which harnesses energy from the Sun for the purpose of providing dietary sustenance to the inhabitants of the Earth. Conversely, the Sun supplies the radiation necessary to heat and light the Earth, which is beneficial to all living systems and/or organisms. Hence, the Sun is the origin of energy. The focus of my essay will be to explore the current ways in which we use the Sun’s energy to supply heat and light on Earth, the advantages and disadvantages of our current energy methods and/or sources, and ways in which we can utilize renewable energy sources and reduce and conserve our current energy consumption.…

    Sci 275 Week 9 Final Project

    As human beings, we need energy for just about all functions associated with the luxuries of our daily lives. We need energy to heat our homes, to fuel our cars, to watch television in addition to industrial and agricultural purposes. How often do we stop and think about where all this energy is coming from? Energy is formed and disbursed through an industrial process that is performed using a number of different sources. Although there are a number of different sources, there are only two types of energy, renewable and nonrenewable. Renewable energy sources are naturally replaced in time. Because of this factor, there is little concern with running out of these energy resources. On the other hand nonrenewable energy resources are quite the opposite. These resources have the potential to run out because they are not replaced naturally in short periods of time.…

    Energy has easily become one of the most important necessities for our everyday lives. Without it we would simply not be able to have transportation or be able to gather any of our other resources that we depend on. If at anytime our energy supply ceases or no longer attainable the results may be horrific. However, it is quite easy to keep this from happening, It is crucial that our current population realize the importance of sustaining our present non-renewable resources. An examination of all the present energy issues and human impacts of energy conservation along with the a resource plan will show importance of energy sustainability how it must be a success.…

    From the moment we wake up in the morning until the time we go to bed each night, we all use different forms of energy to perform our daily activities. On a daily basis I use energy for transportation to commute to and from work and run errands; for cooking meals using either my gas range, microwave or charcoal grill; for heating my home in the winter and cooling my home in the summer; for daily showering, and for lighting my home in order to be comfortable and productive. Most of the resources we rely on for energy are nonrenewable and will soon be depleted.…

    Conserving Energy, Arguing to Inquire

    In order to understand how to conserve energy, there needs to be a definition of what non-renewable resources are. According to Ingrid Kelley, author of Energy in America: a Tour of Our Fossil Fuel Culture and Beyond, coal, oil, and natural gas are called fossil fuels because they were formed from layers of carbon-based organic matter that had been plants and simple marine creatures many millions of years ago (Kelly 14). While they were buried under sediment, these organic layers were concentrated by time, pressure, and terrain into various carbon deposits containing significant amounts of energy, which ancient swamps and forests soaked up from the sun (Kelley 14). This means that the energy that we use today for fuel and power to provide electricity for our homes and offices is a dying source. Fossil fuels take millions of years to be reproduced, and the way America burns through them, it would be impossible for them to be a consistent source of energy. From looking at the way energy consumption is at this point and time it does not seem to add…

    What Is the Force That Moves Continents and Tectonic Plates?

    Energy is an important part of our everyday lives. Energy can come in many different types, and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people's bodies with energy. Another form of energy is how coal is converted into electricity. Fuel is another form of energy that can be used for many different usages as well. Fuel is used for much different reason such as allowing our cars to function and our lawnmowers to cut grass. There are many different reasons why people use energy in the many different ways that we use it. Even though people rely on energy usage, some of the forms of energy we use are very harmful to the environment and even dangerous to ourselves. The harmful and dangerous fuels that we use can be changed to alternative methods of energy usage. There are two different types of alternative energy, which is known as renewable energy. Renewable energy is very resourceful and is able to be used because it is all around us there will not be a shortage of material and it is safer on every living thing and being. Energy and fuel usage just like everything else in the world has its advantages and disadvantages about using it. We must collectivity figure out which source of energy is right for everyone but for now we will find out which is best to use in your…

    Energy Essay

    The amount of energy that the world uses is undeniably tragic and we may not have influence over the national use of energy but we have every opportunity to change ours. Guam is an island of intimate relations, a vast network of cause and effect. There are many ways to sufficiently monitor our use of energy usage ranging from the smallest of acts; cutting down on computer hours, remembering to flip the light switch, or even the simple act of using the stairs instead of an escalator, to the largest of acts; using a bike instead of a car or even air-drying our laundry. We are not only doing our island a favor through sufficient energy procedures but we are doing ourselves a favor as well. The state of our economy is unquestionably in par with our usage of energy, as the uses of energy rises so will our bills. Through cause and effect every choice we make comes hand in hand with an equally weighed consequence. We have the ability to control our choices therefore we control the consequences. If we can make the right choices in energy efficiency then we can achieve the right outcome. Imagine a project for the entire island introducing a more efficient use of insulation, not only would we attain cooler conditions indoors but we would substantially lower the use of energy and our bill towards that. A utopia of efficient energy uses is not far from sight, it is possible by acknowledging the problem, making a choice, and taking action. We live in a “paradise”, so let us be true to that word; energy efficiency, not only good for us, but good for…

    Energy Conservation

    Energy conservation is the elimination or reduction of energy we and waste every. Energy is a very important to our society. We use energy for everything transportation, cooking, heating and cooling, manufacturing, lighting, and entertainment. Energy is the vital force powering business, manufacturing, and the transportation of goods and services to serve the American and world economies. Can you imagine what life would be like if we did energy? Every year the United States spends over 500 billion dollars on energy. As you se we use a lot of energy. Accordibg to Doe “The average American family spends more than $1,600 a year on home utility bills.” Energy is the foundation for everything in life. We rely on energy to make our lives comfortable, productive and enjoyable. Energy conservation is most important because it is where we get most of our energy from non-renewable energy sources. Nonrenewable energy sources come out of the ground in forms of liquids, gases and solids. These sources include, nuclear, natural gases, and coal. They are considered nonrenewable because they cannot be replenished in a short period. Actually, it can take thousands of years in order for them to reproduce themselves. As of now, crude oil or (petroleum) is the only naturally liquid profitable fossil fuel. In addition, natural gas and propane are normally gases, and coal is a solid. If these nonrenewable run out they will become to costly to harvest then humans would have to use other sources for energy. Scientist believe that coal, petroleum, natural gas, and propane are all fossil fuels because they where formed from non living factor such as buried remains of plants and animals that lived millions of years ago. A final non-renewable energy source is Uranium. One would think Uranium is a fossil fuel, but it is not. Uranium is a…
