Energy resources
Energy resources are things that can provide energy to give light, heat or provide mechanical power. Energy resources are; wind, coal, solar energy, geothermal wells, ocean tides and moving water. Some energy resources can be transformed and transferred from their natural form or location to be other consumption sites (Dewulf 2221).
We shall discuss electricity and coal. Electricity is obtained from the environment by harnessing mechanical power from wind, moving water, ocean tides, coal and others. We shall focus on electricity collected from geothermal wells (Ruth 36). Steam is gathered and directed to turbines that rotate generators to produce electricity. Coal is mined from fossil sites in solid state. Electricity is the most versatile form of energy as it is found in many forms and can also be used for lighting, heating, running electronics and others. Unlike electricity, coal can be used in fewer applications mostly to heat and production of mechanical power. Unlike electricity, it is bulky and emits carbon dioxide that is harmful to the environment therefore, it is limited in usage. Contrary to coal, electricity can be transported miles away from the thermal station with extremely low costs and delivered instantly unlike coal that will have to use road or rail and transported to consumers.
Geothermal energy is gaining popularity as it is a clean energy source while coal is losing and becoming outdated (Zavattoni 124). Geothermal energy is obtained from wells and has very little cost in comparison to coal. Coal produces heat and emits carbon dioxide as a by-product.

Energy Resources and the 21st Century

...Most conversations regarding the planets energy resources and their appropriate place in today’s society reveal extensive ignorance on the subject and deliberate misinformation by both sides of the argument;, the energy producers and the environmentalists. Any honest appraisal of the future of global energy must begin with a full and balanced understanding of resources and their uses. The earth provides us with two basic natural energy resources, fossil fuels and renewable flows of energies stemming from the heat of the sun, as solar energy and the winds which circle the planet, as well as the movement of water and the internal energies of the planet (geo-thermals). Fossil fuels are the products of the conversion of biomass, which, through fossilization, yields coal, oil and natural gas. Coal became the world’s most important solid fuel during the 1890s, when their energy content surpassed that of the traditional fuels of the day (wood and crop residues). Today, coal provides less than 25 percent of the world’s total primary energy supply. A ton of coal has an energy equivalent to about ½ ton of crude oil. The energy content of all crude oils and liquids produced by their refining is very similar: about twice as large as that of coal and almost three times as large as that of cord wood. Crude oil became the world’s most important primary fuel during the 1970s and now it provides about 40 percent of the world’s total primary energy supply. Natural gases are usually......

Energy Resource Plan important to conserve energy especially when it is produced by non-renewable resources. We use non-renewable fuels to crank our cars, to hear our homes and to cool our homes. When pollutants from these non-renewable fuels are released into the air it contaminate the air we breathe along with the water that we drink. With that being said it is important to conserve energy to keep the air that we breathe cleaner. Conserving energy is also important because it reduces the electric bill and the gas bill which in turns save you money. Using renewable resources are the better ways to conserve energy and to maintain a healthier atmosphere for all humans, plants, and animals. There are two types of energy resources and they are renewable and non-renewable resources. There are three top renewable resources and they are but not limited to solar energy, wind energy and hydropower. Solar energy comes directly and indirectly from the sun which contributes to the growth of plants and trees. Wind energy is the movement of air when warm air descends and cooler air comes in. This type of energy is beneficial for sailboats. Hydropower comes directly from the energy of flowing water which make electricity. All of these renewable resources come directly from the earth. Non-renewable resources are coal, petroleum, natural gas, and nuclear energy. These resources come from underground and most of them derive from the fossil of dead plants and animals. This resources are not reusable......

Energy Resource Challenges

...Energy Resource Challenges SCI/275 Joshua Dodson 11/04/11 Renewable energy alternatives have many challenges, and managing these resources has become a nightmare. Renewable alternatives such as wind, solar, biofuels, and hydroelectric have become very popular as an alternative to nonrenewable energy resources. The first renewable energy alternative is wind energy. Because wind will always be around, the use of wind turbines is an energy alternative. A big challenge is that we cannot control the wind; some days it is strong and other days it is calm. Solar energy is another energy alternative. Photovoltaic solar electricity is the technology that is most cost effective to consumers in the United States. The greatest challenge to solar energy is that for 12 hours a day we do not have any sunlight, and there are days when it is to cloudy. Biofuels are derived from biomass (organic material) plants and animal waste. With today’s technology we can gather the leftovers from a harvest of corn such as, stalks, and stubble to produce ethanol. The challenge with this process is that it takes a great deal of organic material to produce a small amount of biofuel. Another renewable alternative that was not mentioned is hydroelectricity. The use of dams to produce electricity is very costly, and it takes a great deal of water to generate a small amount of electricity. Nonrenewable energy resources include coal, oil, and natural gas, which pollute our......

Energy Resource Challenges

...Energy Resource Challenges Checkpoint SCI/275 August 25, 2010 Bridgette Mack The Alternative video talked about different types of renewable energy wind power, solar power and biofuel. Wind power a method that solely depends on if there is wind that will make these very large turbines turn and if there is no wind they don’t turn. Another type of renewable energy would be solar power and it depends on the sun and uses panels that collect sun light beams and with the use of generators to form energy. You also have biofuel that is use to produce ethanol which comes corn scientist want to use other materials from farmers after they have harvest their land to see if it can also be made into liquid fuel. Having a different method of energy I think would be good especially if these methods aren’t harming our environment but with the good there is some bad. The challenges I think would be with wind energy this object depends on if the wind is blowing strong enough to turn those turbines and what if there isn’t any wind at all that mean there no energy to produces and the solar panel I think would be costly in the begin and they may off in the long run but it would have to take many miles and much land to produce enough of these panels to supply everyone with solar power and what it there is no sun what then. One other source of renewable would be water power which you can produce power from the use of water. I think that we need to start now to find some other way to......

...meeting to discuss the importance of the energy issue we are facing in our community. The reason why conserving energy is important right now is so we can save our environment from further damage, conserving energy will also save our community money. We need to know the difference between renewable and non-renewable resources, and what methods we need to take to conserve energy. Non – renewable resources are oil, coal, natural gases, and nuclear energy; non - renewable means that once we run out it cannot be replaced. These non-renewable resources are also harmful to our environment with their chemicals when burning fills our air, and their leaks and spills of oil in our ocean. Renewable resources are solar power, wind, biomass, tidal energy, and a few more; renewable energy generates directly from the sun, wind, rain, and tides. Renewable technologies will save money and boost our economy in the process. Each of you can help save energy indoors by: 1. turning off lights and electronics when not in use 2. use energy saving light bulbs 3. insulating your doors, and windows and the environment by: 4. plant trees 5. recycle 6. drive less The government effort in conservation has many applications for helping our environment. “Opportunities for energy conservation are increasingly available in almost every application in any setting. Home, school, office, and industrial environments have all benefited from cost-saving and energy-saving innovations” (U.S.......

Midland Energy Resource

...Midland Energy Resource Report for Cost of Capital October 16, 2014 Abstraction General Analysis of Midland Energy Resources Cost of Debt • • • • Consolidated Company Exploration & Production Refining and Marketing Petrochemicals Cost of Equity Equity market risk premium of 5% is reasonable. According to the Exhibit 6, the U.S. stock return minus Treasury bond yields for each period varies. Since each period has different standard error, it will be better to take the weighted average of the data, then EMRP is approximately 5.9% or lets say 6.0%. Comparing to the EMRP that Midland would use in the calculation of WACC which is 5%, the historical data reflects a higher EMRP. But from the market risk premium survey results, we see that finance professors, CFOs and fund managers advocate a lower rate on risk premium. Because these people have better understanding in the performance of the market and be more aware of how economics works, then the analysis from them should be taken into great consideration. Therefore, 6.0% from the past data balanced with some lower rates that suggested by bankers, auditors as well as Wall Street analysts, 5% should be appropriate. Weighted Average Cost of Capital WACC = λ(1 − t)KD + (1 − λ)KE The Effect of Leverage on the Cost of Equity and WACC Cost of Equity The relation between cost of equity and leverage can be shown as follows: βEquity = 1 βU (1 − λ) Asset Cost of Equity = Risk Free Rate + βEquity × (Risk Premium) We further......

Energy Resource Plan

...Energy Resource Plan Andria Cogar Axia College Our utility bills have been increasing in past months that have raised many questions about the cause. Is no one in the family is turning off the lights when a room is not being occupied, doing less than a full load of laundry, and not taking shorter showers? Energy conservation is on the rise, even though few try to stick with what will make the environment better. Conserving energy can be helpful in a number of ways; whether it be to save money for a family vacation, decreasing pollutions in the air we breathe; or just stopping the amount of green house gases being emitted into our atmosphere. We are using nonrenewable energy to supply us with energy to cook, clean, and keeping us warm; without even thinking of its consequences, which in turn will not last forever. There are distinctions between nonrenewable and renewable energy that will help in the future to ensure a better way of life. Nonrenewable energy is energy that comes from the ground, and is not replaced in a short amount of time. Fossil fuels are the main source of nonrenewable energy, which includes; oil, natural gas, and coal. Steaming from plants, and animals’ decomposed remains; that have been in the soil for millions of years. Renewable energy is energy is energy that replenishes itself automatically from natural processes. Examples include; wind, sunshine, biological processes, flowing water, and geothermal heat flows are all methods of renewable......

Energy Resource Challenges

...Week Eight Checkpoint Energy Resource Challenges SCI/275 Cindy Walker Conserving energy is a key factor in the improvement of the planet in which we live. I practice conserving energy by doing little things such as turning lights off when I leave the room and turning the heat or the air conditioner down a little lower than I normally would. I believe if everyone in the world would take these little steps we can make a momentous impact on the environment. Natural gas and oil are the most common natural resources used to run our homes efficiently. Consequently, these natural resources can and will run out in the future if we do not begin to conserve today. I have challenged myself to reduce the size of the ecological footprint which I put on the earth. I am proud to say that I am a recovering shopaholic. You see, I am a mother of three little girls and love for them to look their best at all times. So, I would go out and buy them new clothes for just about every occasion. During this time I thought I was being resourceful by purchasing cheap trendy clothes for them to wear instead of the more expensive higher quality clothing. However, after completing an environmental science course, I realized I wasn’t being resourceful; instead I was being quite wasteful. I realized that buying a large amount of cheap trendy clothes was costing me more money and creating more trash than buying higher quality clothing. I noticed that the cheap clothes could only be worn a......

Natural Resources and Energy Paper

...Natural Resources and Energy Paper A forest is a natural resource needed by the earth, humans, and species. There are three types of forests. The three types include “tropical, temperate, boreal forests” (The forest biome p. 1, 2006). Recently forests occupy about “one-third of Earth’s land area, and account for over two-thirds of the leaf area of land plants, and contain about 70% of carbon present in living things” (The forest biome p. 1, 2006). Forests produce vital oxygen and provide homes for people and wildlife. Forests play a critical role in mitigating climate change. A forest have several management practices for sustainability and conservation. There are several risks and benefits of extracting and using one type of nonrenewable and one type of renewable energy. The growth of human population has affected forest resources in several ways. The affected forests have caused harm to the population of wild species and have majorly impacted agriculture. Impacts associated with agriculture Between 2000 and 2010 about 13 million hectares of forests were lost per year to agriculture and other uses (Food and Agriculture Organization of the United Nations, 2013). Agroecosystems are very different from the ecosystems seen in nature. Unlike natural ecosystems, agroecosystems are large areas that have been planted with a single species or single strain or subspecies. This often makes them more susceptible to disease. Also, the agroecosystems are often planted in simple......

Energy Resource Challenges

...renewable energy alternatives to compete with fossil fuels are described. Among them presented in this video were wind power, solar energy, and biomass fermentation. Although each of these energy sources provides efficient energy without extensive harm to the environment from byproducts, they each possess their own challenges while using and managing them. Wind power is generated through the use of a turbine, usually mounted on a tower. The turbine collects wind energy and converts it to electricity which is transferred to your houses breaker pane. Energy from wind powered devices depends on strong enough winds to move the large turbines, which makes the turbines create energy. Without wind to spin the turbines, energy would not be created through this method. Solar energy is energy produced from the sun using panels. Solar panels are very expensive to purchase and maintain. A challenge with using solar panels is the intensity of sunlight affects the output of energy. If the solar panels do not receive enough sunlight, they will not produce enough energy for use. Biomass Fermentation involves converting biomass into ethanol. The fermentation process converts sugars into ethanol using yeast or bacteria which feed on sugars. Ethanol and carbon dioxide are produced as the sugar is consumed. A challenge with using biomass fermentation as a means of energy is getting farmers to collect the material after harvesting to convert it into fuel. In addition to the renewable......

...Energy Resource Week 8 There are several types of renewable energy available for use. Solar, wind and are at the top of the list. Others that are beginning to generate more interest are grains and corns by products. Due to higher costs for fossil fuels people are looking at all the alternatives. The rising cost of gasoline is challenging people to think outside the box. [The National Renewable Energy Lab uses leftover cornstalks and stubble to create a fuel grade ethanol] (University of Phoenix, 2008). The idea is good in theory. However, the feasibility of transporting the leftover cornstalks and stubble to a plant that would convert it to a fuel might be too far a distances to make it worthwhile. Another option is solar power, using the sun can produce clean electricity, to power a home or charge a car. [Excess electricity from an efficient solar electric system can be sold to the electric company generating money for the owner] (University of Phoenix, 2008). The renewable energy sources are becoming more competitive as energy prices increase. [Wind power is being heard near the Rocky Mountains when the wind picks ups] (University of Phoenix, 2008). Decreasing the usage coal, oil, and natural gas is vital to our existence on earth. These resources are nonrenewable; they will run out, they cost too much to produce, and the impact of taking from the earth is harmful to the environment.

Midland’s corporate treasury staff had begun preparing annual cost of capital estimates for the corporation and each division in the early 1980s. The estimates produced by treasury were often criticized, and Midland’s division presidents and controllers sometimes challenged specific assumptions and inputs.
