From Fossil Fuels to Renewable Energy Essay Example for Free

From Fossil Fuels to Renewable Energy Essay The gas pump. As of late, it has been the bane of drivers everywhere. With the prices of crude oil skyrocketing combined with the prices at the pump and nearly everywhere else, many people are looking toward renewable energy sources to supplement or replace the use of fossil fuels. This interest in renewable resources has generated new energy policies around the world, has spawned new energy technology and has produced ideas on a different way of living. Adding to the interest is the awareness on humanity’s impact on our environment, there is so much interest that the United States and many other countries have started to explore the option of producing power by the cleanest sources possible. However, it may not be enough. With the threat of oil reserves being used up and the energy crisis unresolved it is imperative that the United States begins to utilize solar, wind, and hydroelectric power in an effort to decrease the dependency on fossil fuels. Many people notice the rising costs of just about everything. The rising costs are due to the rising cost of energy. Nearly everything in our economic system requires energy to create, to ship, to stock, or to provide and the energy costs are passed down to consumers. The price for energy has not been terribly high in the past, but now the price is rising. One look at your electric bill will tell you that energy, however inexpensive it is to make or obtain, does not come cheap; at least, not anymore. The price of fossil fuels, not just in a monetary sense, but in an ecological sense is taking a toll on the country and the world. Acid rain, carbon dioxide and global warming are all consequences of cheap acquisition of energy. Coal supplies a large part of the energy needed to produce power in US and is one of the largest sources of energy in the world (Energy Perspective, Walter Deal 2006), but strip mining ruins the landscape, destroys ecosystems, and when burned causes acid rain. Oil has been this country’s, and the majority of the world, most used form of energy for years. From powering our vehicles and homes to creating lubrications and solvents, its uses are prolific. But we’re are now faced with the possibility of oil supplies becoming scarce, and it has everyone jumping out of their pants to find a better source of energy. Combine this with the fact that the by-product of using oil (carbon dioxide) is practically burning a hole in out atmosphere and we have a doozy of a problem. Enter renewable resources. Why have we not thought of this before? What has kept the US, and indeed the world, from investing in renewable resources much earlier? The answer is technology. The green energy has always been there, but the capabilities to harness the forces were not advanced enough to take advantage of it. Perhaps it still has not reached that level yet but we are getting close. For years, people have used the sun for a variety of things: warming things, lighting torches, burning ants, and to cook. The energy radiated by the sun is phenomenal. In fact, the energy the sun shines onto the earth daily is enough to supply the world’s yearly energy needs (National Geographic, 2008). This energy potential of sunlight was not lost on seventeenth century scientists. In 1873, William Adams and Richard Day found that when selenium was exposed to sunlight it created a low charge of energy, though it could not power anything (US Dept of Energy, 2008). Later on, in 1908 William Bailey invented the solar panel whose design is extremely similar to the solar panels used today. Solar energy technology, while not developed enough to harness the full power potential of sunlight, has been used consistently since the mid-1960’s to power satellites, spacecrafts, electronics, cars and homes through the use Photovoltaic cells (US Department of Energy, 2008). The Photovoltaic cell, which produces electricity when light strikes the cell causing an electron imbalance, has gone through numerous transformations to make the cell as efficient as possible. There are solar plants littered across the country, most notably in Kerma, California where they use the Photovoltaic system to supplement Pacific Gas and Electric’s electric grid during peak power usage (US Dept of Energy, 2008). These cells can be used in homes across the country and the current technology has created a Photovoltaic cell that is more durable, flexible and easily maintained. In addition to Photovoltaic cells, parabolic trough mirrors, parabolic dishes and power towers use mirrors to direct the sunlight to a specific area where it is used to create steam, that steam is then used to create electricity (The Economist, 2008). Now SolarReserve, a development firm partnered with United Technologies and US Renewables Group, has designed a system that will capture and store sunlight for several days. The system is similar to traditional capture of sunlight by using mirrors to direct sunlight to towers where molten salt is kept, usually a collection tower. The salt is heated by the sunlight, which can then be stored or used immediately. Since molten salt is an efficient heat carrier and storage medium, it can create energy on demand or stored for later power production thus solving the problem of power generation during cloudy or stormy days. SolarReserve first demonstrated this technology at their site in Barstow, California and states that the technology is ready to be used for power production on an electrical grid (Wald, New Ways to Store Solar, para. 13). The benefit of this type of solar technology, and other solar power production, is that the fuel source is free. The acquisition of sunlight requires no drilling, no decimation of land and no major disruption of fragile ecosystems. Solar power is also a clean energy source, giving off no emissions in addition to being abundant and renewable. Sunlight also creates another renewable resource. Wind. The power of wind has been harnessed to irrigate, to grind grains, and to produce electricity. Turbines here in America only provide 1% of the electricity consumed, but the potential for the wind industry is huge. Several countries around the world use wind as a portion of their power generation. Denmark, for instance, generates 20% of their energy from wind. Spain has generated 8% of their power from wind and they are expected to raise that number in the next year (Greenpeace, 2008). Early wind turbines were used to grind grain and to bring water to irrigate crops, now the turbines are created to crank out electricity. Wind farms are cropping up everywhere; just recently T. Boon Pickens announced that he was partnering with General Electric to build the world’s largest wind farm in Texas (The Economist, 2008). This partnership comes about due to the suddenly lowered costs of turbine production. Couple that with the fact that, aside from the cost of construction, the generation of the electricity is free and (theoretically) will not go away, you have a deal of a life time. Current turbines have become more reliable than earlier ones; they are easily built and generate power as soon as they are up. Some snags manufacturers of turbines and the electric companies have come up against are the questions of storage, the issue of visual impact or noise pollution, and the effect turbines have on animals. Electric grids have traditionally used alternating current to transfer power to the grid; however, the location of turbines can sometimes be remote places, which can mean that power is lost in the transportation to the grid. The non-traditional idea of using direct current has cropped up, since direct current travels well over long distances and there is less power loss, using direct current grids to transport the power to areas where the energy can be used effectively solves the transportation dilemma (US Department of Energy, 2008). The use of DC instead of AC forces a change in the way power is transported on a grid and although many balk at the idea, Europe has already a similar system in place and plans on extending it to the United Kingdom. The system pushes power to the grid and channels excess power to help push water uphill to Norwegian hydroelectric systems. While wind has been making leaps and bounds in technology and production, the hydroelectric systems in Europe and most of the world have helped power these countries for years. In reality, hydropower has been used for centuries around the world and it had been used in ancient Greece to turn water wheels to grind wheat into flour (US Dept of Energy, 2008). The water wheel is probably the most well known way of producing energy from water, and it was this early application that spawned the idea for current turbines. The amazing thing about water is that it is perpetually recycling itself. It is evaporated into the air from oceans and streams then comes back to the ground to start the process all over again. This process is what makes hydroelectric power so attractive. Unfortunately, although hydroelectric power accounts for one fifth of the world’s power generation and is the cheapest source of energy, the building of dams can displace wildlife and destroy ecosystems. There have been some advances to making dams more eco-friendly though. By building fish ladders and developing aeration techniques, installations can have a minimal impact on wildlife and the environment (National Geographic, 2008). There are even some technologies that are being developed to harness the power from ocean waves. With mechanisms similar to wind turbines, the energy in the ebb and flow of the tides is captured to produce clean energy. Unlike wind energy, tidal energy is constant and easy to predict, which makes â€Å"coordinating the flow of electricity in the grid quite manageable† (Holzman, 2007 para. 7). Tidal turbines are also easier on the eyes. Whereas wind turbines and solar plants may mar a skyline, tidal turbines are generally not visible at all. While you may see commercials and ads touting the beneficial effects of renewable energy going on right now, the generation of clean power is not an immediate process. It is going to take a lot of hard work and a great change in lifestyle to accomplish it. Although there are many companies working hard to provide the technology or the means to produce clean power, consumers can help by investing in green energy. Many utility companies offer a green power program that allows consumers to donate a portion of their power bill to the research and development of clean energy (Environmental Protection Agency, 2008) and consumers can get tax credits for energy efficient home improvements. Although renewable resources such as solar, wind and hydroelectric power may be expensive at the outset, the use of clean energy will pay for itself in terms of environmental impact, and especially its renewability. Because it is not a change that will happen over night, it is important for consumers to remember that they too can assist in investing in the future of renewable resources. By donating a small amount every month through their power company a consumer can help his or her utility company pay for the additional costs that are accrued in using green power and the new technologies to generate green power. If a change is to come, everyone has to be on board and willing to change their lifestyles from the current â€Å"throw away† lifestyle. Change for the better has to come from consumers as well as the pioneers of renewable energy. References The power and the glory: A special report on energy (2008). The Economist, 387(8585), 1-14.

A Summons to Memphis :: essays research papers

This novel by Peter Taylor opens with James and Mary Tyrone talking. They seem to be a very loving, married couple. James compliments Mary many times about how beautiful she looks. However she seems to be insecure about her looks because she is discontent with her case of rheumatism in her hands which makes it shake all the time. Then they heard their two sons laughing, as they walk out from the dinning room. As Edmund and Jamie enter, their parents question them what they are talking about. Edmund tells the story of Harker and Shaughnessy, which he had heard from the night before. Then afterwards Edmund and Mary leave the scene, and only James and Jamie is having a conversation. They seemed worried about Edmund who is sick with a â€Å"cold,† so they hoped, but in reality they know it’s not just that. They are also worried about Mary, but it is not yet revealed what is wrong with her. James and Jamie then leave to go work out on the hedge as Mary and Edmund begins to talk. They show a loving mother and son bond, they both care a lot about each other’s health. After their talk, Mary went upstairs to rest as Edmund remained in the parlor reading. Continuing to the next scene, James and Jamie comes in from outside for lunch. They must wait a while though because James was still talking to Captain Turner. Jamie seems to imply that his mother is doing something that she has done in the past that wasn’t too good for her, but it doesn’t indicate what it is yet. Then James comes in and also says that something is wrong with her, but does not say what it is. He just say that he that why didn’t she have the strength to keep on, but Mary acts as if she does not know what he is talking about. After lunch, they all follow Mary back into the parlor. Mary is talking about how their home is not really a home, and then the phone rings. It is Dr. Hardy. He has called for Edmund to come up to the office to see him that afternoon. When Edmund and Mary leaves the scene, James and Jamie begins talking about what the Doctor said. Hardy told James that it was sure that Edmund had â€Å"consumption,† and must be sent to a sanatorium, which will cure him in a year.

Ceres Gardening Company Case Study Essay

1. How has the company grown? What is its basic strategy + how has it evolved? What have been the key factors in the company’s growth? The growth of the company has been fueled by the market demand growth in organic products. Ceres increased their revenues by over 75% in just five years, while growing profits by over 25% (based on Exhibits 2, 3 & 4). Ceres’s basic strategy started with its founder, Jonathan Wydown, to promote sustainable organic gardens and landscapes to environmentally conscious consumers. Mr. Wydown has been a proponent of soil preservation, biodiversity, and natural fertilizers and pest control. Mr. Wydown was confident that the same principles behind organic farming would eventually apply to home gardens and lawns. Mr. Wydown’ s vision evolved into the creation and development of a market niche of selected certified organic seeds and seedlings for vegetables, culinary herbs, and flowers – bringing the farm to the home per se. This market niche and products became the company’s differentiator and competitive edge. The key factors that drove the company’s growth are: * Market demand and segmentation – Ceres developed a market niche for organic-conscious consumers who are concerned about the environment. Although products are priced at a higher premium, the value from the company’s environmentally conscious go-to-market strategy and segmentation allowed Ceres to develop a loyal consumer community. * Product Offerings – Ceres expanded its products offerings to include open-pollinated, organically grown, and heirloom varieties of seeds and seedlings for vegetables, culinary herbs, and flowers. The company also added live plants, such as one-year-old trees. * Production Strategy – Ceres’ principal farm was located in central  California. As the demand for Ceres’ products increased, Ceres’s production capability was challenged. To keep up with the increased demand, Ceres developed a network of small, independent organic farms, offering them a commitment to purchase goods in exchange for an exclusive supplier relationship. These further strengthened Ceres’ production capability. * Distribution Channel – In the early years, Ceres operated primarily as a mail-order catalog company. This was their main distribution channel. The operation was ran well and valued for its quality, reliability, and hands-on customer service. Moreover, Ceres provided a free bimonthly company newsletter, which included gardening tips, introduced new products, and created a sense of community among the expanding customer base. This alternative marketing expanded Ceres’ channel from one time purchase to future incremental (post-sale) revenues. Eventually, Ceres expanded its channels to include retail channels, and direct sale through a sales force model. * GetCeresâ„ ¢ Program – enabled the average nursery or garden center to stock a sufficient inventory of Ceres’ products to meet the seasonal demands of the customer. If a retailer ran out of seasonal products, the customer would probably not return later, thus a potential loss of sale. Essentially the program meets the challenge of having the plenty of stock of the right product in the store at the right time based on consumer attitudes, behaviors, and preferences. The program also provided incentives to retail storeowners by offering deep discounts to carry inventory and extended payment plans. 2. Questions 3.1. How is Ceres’ financial health? Which specific items in the supplemental financial statements + which ratios might you calculate/research to help you assess its financial health? The financial health of Ceres is excellent and continues to show a positive trend from 2002 to 2006. (Please refer to Table 1) * Current Ratio shows Ceres’ ability to pay short-term obligations. The current ratio indicates that the company would be able to cover its liabilities in 2002 2 times over. * Quick Ratio measures Ceres’ ability to meet its short-term obligations with assets excluding inventory. The quick ratio indicates that Ceres would be able to cover liabilities 1.6 times over. * Debt Equity shows Ceres’ financial leverage and its aggressive posture in financing its growth with debt. The company could potentially generate more earnings than it would have without this outside financing. This indicates that even with Ceres’ expansion of distribution channels, extension of payment terms, and the creation of a direct sales force, Ceres was able to manage to stay below 1 with a mean average of .74. * Inventory Turnover shows an efficient turnover of inventory. Ceres does not hold inventory for long periods of time, which can incur additional costs by having assets sit without revenue generation. It shows Ceres’ ability to manage inventory in a seasonal cycle and further indicates their ability to forecast demands on product movement. * Accounts Receivable shows Ceres’ effectiveness in extending credit as well as collecting debts. The extended payment terms appear to be working. The prompt collection of debts enables Ceres’ to use the monies to reinvest into the business. 3.2. What should Ceres’ strategic plan be, given the trends in the organic gardening market? A move forward strategy is a renewed focus on market penetration and diversification of product portfolio. As the CMO, Annette O’Connell reported, â€Å"Growth in organic gardening products is strong, and the trends should support long term growth.† Market Penetration – capitalize on the movement from wholesale organic farming to weekend home gardeners and food service industries. While Ceres can continue to cement their market share in organic farming, the weekend gardener and food industry market are prime market niches. To reach these markets, Ceres has to diversify its product portfolio. Product Portfolio Diversification – Ceres’ has to consider diversifying its product portfolio from materials (i.e. seeds, samplings, 1-year-old fruit trees, etc.) to services and solutions to help organic farmers, food service industries, and weekend gardeners on the â€Å"how to’s† of organic gardening. You not only sell the seeds but also help the consumers manage the gardening process thus providing Ceres a â€Å"market differentiator† as a one-stop consumer experience. 3. How would you evaluate Ceres’ marketing efforts? Should the Ceres program be expanded? Why or why not? The GetCeresâ„ ¢ Program is a sound marketing plan but can be fraught with challenges if not managed effectively. The main purpose of the program is to address inventory and â€Å"enable the average nursery or garden center to stock a sufficient inventory of Cere’s organic products† by having the right products in the stores at the right time. Bottom line – help Ceres increase sales by helping business partners manage their inventory. With that said, stores and business partners are not willing to carry inventories on their books if they are not able to churn it appropriately. To alleviate angst and potential cost exposure, Ceres extended their payment terms from 75 to 90 days to 120 days and a 15% discount the storeowner or business partner agrees to hold a minimum stock inventory. To help protect Ceres’ average gross margins, it successfully raised prices slightly on most of its products. 4. Questions 5.3. In your opinion, did Ceres hire the right CMO? What role did that play in its financial situation? In our opinion, Ceres hired the right CMO. Through the CMO leadership, distribution channels were expanded from mail order catalog to an expanded network of storeowners and retail merchants. The CMO further increased their market reach by developing a direct sales force and the appropriately compensation plan. Inventory was managed efficiently through the introduction of the GetCeresâ„ ¢ Program. Overall, the company’s debt equity, inventory turnover, and accounts receivable ratios showed a positive trend and continue to forecast a better future. 5.4. Why is it important to ensure that you hire someone who is the â€Å"best fit† – for a position? It is important to hire someone who is a best fit because of the notion of a â€Å"shared vision† and â€Å"common values.† A strategy remains to be a strategy without the proper tactical execution. Both Wydown and O’Connell agreed,  Ã¢â‚¬Å"The best way for Ceres to build its competitive position would be to push even more aggressively† to increase profits and lower margins by expanding distribution channels and market footprint. O’Connell had a background in retail and consumer packaged goods. This was the â€Å"best fit† for Ceres’s CEO, Jonathan Wydown whose strategy for growth was to move from a mail order catalog model to building a retail presence. Wydown and O’Connell believed that Ceres’ reputation for quality and customer service would give the company an advantage over the competition. 5. If you were CEO Jonathan Wydown, what would you plan to say during your upcoming meeting with the bank – regarding Ceres’ growth prospects + cash flow projections for 2007 and the near future? During the upcoming meeting with the bank, the focus should be given on the debt equity, inventory turnover, and accounts receivable ratios and how well the company has managed its operations over a sustained period (i.e. 2002 to 2006). From the Balance Sheet provided, it is evident that operational, financing, and investment cash flow is positive. The market-projected growth is 8% to 10% per year. Ceres has kept pace with the overall industry, but Ceres has to review its financing model to sustain their own growth in the market they chose to compete in order to continue having a competitive edge. As such, the bank discussion should center on the increase of revolving credit and capitalization of investments to continue to fund the retail distribution model.
