Pros and cons of renewable energy - wind power, solar and biomass.
Advantages and disadvantages of wind power A wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. Advantages * The wind is free and with modern technology, it can be captured efficiently. * Once the wind turbine is built, the energy it produces does not cause green house gases or other pollutants. * Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue. * Many people find wind farms an interesting feature of the landscape. * Remote areas that are not connected to the electricity power grid can use wind turbines to produce their own supply. * Wind turbines have a role to play in both the developed and third world. * Wind turbines are available in a range of sizes which means a vast range of people and businesses can use them. Single households to small towns and villages can make good use of range of wind turbines available today. Disadvantages * The strength of the wind is not constant and it varies. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce
La Mesa Watershed
Michael Diamond February 27, 2009 Block F Mr. Cheatle The Current State of Water Supply to Metro Manila from La Mesa Watershed A) The Physiological, Hydrological, Ecological and Management Issues at La Mesa Watershed Reservation . Introduction La Mesa Dam (Figure 1.0) is located in the Novaliches Watershed. The Novaliches Watershed is a drainage basin that covers land in Quezon City, Caloocan City and the Rizal Province. The drainage basin surrounding the La Mesa reservoir covers 2700 hectares, of which 2000 hectares is forest cover. It supplies around 4 billion liters of water per day. Ninety seven percent of Metro Manila's water supply comes from this source. Therefore, careful management is needed for this area, because of its vital importance to the health and life of the 12 million people in Metro Manila. This report will showcase the physiographic features and vegetation of La Mesa. It will also explain the hydrological system of La Mesa, the water supply, the way the water is treated and made safe for drinking. Finally, it will also include ideas as well as the pros and cons for new water sources. Figure 1.0 2. The Setting: Physiographic Features, Vegetation, Soils and Rocks Figure 1.1 The main physiographic features include: a gently
How the types of shops in Stourbridge Change from street to street.
CONTENTS Study Area- 2 Study Area I am doing my survey in the dormitory town of Stourbridge, which is just outside Britain's second city of Birmingham and is on the edge of an area called the Black Country. Most of the people who live here usually commute into places like Merry Hill or into Birmingham where there are more jobs. The main industry in Stourbridge is its glass works and it is world famous for building the first steam locomotive to run in U.S.A called the Stourbridge Lion. Introduction The issue that I am going to be studying is how the types of shops in Stourbridge Change from street to street. This would be a good topic to study because of the different types of shops in the area vary a lot and I can see how the increase of the retail market in the area has attracted different types of shops there. I am conducting my study in Stourbridge town centre, which is the central retail district (CBD) in the area. There are three main streets in the town centre High Street, Talbot Street and Market Street. There is also a main covered shopping centre called the rye market where the main shops are. I am doing Talbot Street and Market Street as one whole street as the lack of data I got from the each street. Aims I intend to prove that the groups of shop in Stourbridge town centre are based on where their competitors in the shops field are. Hypotheses My
An Attempt to Delimit the C.B.D of Stamford.
G.C.S.E Geography Coursework An Attempt to Delimit the C.B.D of Stamford- Introduction: The aim of this coursework is to define the edge or the boundary of the Central Business District of Stamford. Stamford is a market town that is situated 100 miles north of London, just off the main A1 road to York and Edinburgh. It is located at the southernmost tip of Lincolnshire, where it meets the counties Cambridgeshire, Northamptonshire and Rutland. Stamford is part of the South Kesteven District. The town is centrally located to the east of the existing motorway network and has good links to the rest of the country. The C.B.D is the central area of the town, which contains the main concentration of shops, offices, places of entertainment and public buildings. These are some of the characteristics of the Central Business District: ) Multi-storey development-High land values force buildings to grow upwards so the floor space of the C.B.D is much greater than the ground space. 2) Concentration of retailing-High levels of accessibility attract shops with high range and threshold characteristics such as department stores in the most central areas and the specialist shops in less accessible areas. 3) Public transport is concentrated-There is a convergence of bus routes on the C.B.D. 4) Few people live in the C.B.D- These are limited to a few luxury flats as well as some
Hurricane Felix Hurricane Felix was the 6th named tropical storm and the 3rd hurricane of the unusually active 1995 Atlantic hurricane season. Though it never made it to land, Felix stalled off the coast of North Carolina, resulting in great uncertainty over its track. The hurricane caused eight Deaths and severe beach erosion from North Carolina to Massachusetts. Storm Path A tropical Wave moved off the coast of South Africa on 6th August. Deep Convection rapidly organized around the centre, and the system progressed into tropical depression seven on the 8th while a short distance Southwest of the Cape Verde Islands. The depression moved to the West-Northwest, and 18 hours after forming, it developed into tropical storm Felix. It continued to slowly intensify as it moved West-Northwest ward, a motion due the subtropical ridge, an attained hurricane status on the 11th while 620 miles (1000 Km) East-Northeast of Guadeloupe. A break in the deep layered trough over the western Atlantic Ocean resulted in Felix moving more to the North-West. There, where waters are warm and little upper level shear allowed the hurricane to quickly peak over 140 mph on 12th August. An eye wall replacement cycle, combined with upper level shear from its anticyclone being displaced over the hurricane, caused Felix to weaken and develop a broader inner core. Its Northwest motion continued,
Changes to the countryside, comparing the present day with fifty years ago.
Cara James, 7T (TE6) Monday, 5th February 2007 Changes to the countryside Present day contrasted with fifty years ago There is a huge contrast between the type of farming we have in Britain today and the farming we had fifty years ago. Machines, modern equipment, large commercial farms and chemicals did not exist in Britain fifty years back. Although all these modern day inventions have helped to make farming a lot easier and there is more environmental awareness, not all changes have been for the better. Forty years ago England was only producing 1/4 of the food that we consumed, all the rest of the food was imported mainly by ships! But in world war two, the German navy bombed many ships that were importing our food, or the food did not reach us for whatever reason. It was only then that the government started to pay farmers more money to grow more crops, and to get their buildings and farms up to scratch. As farmers got paid more money and the government began to take farming much more seriously, encouraged the production and development of machinery and fertilizers. The types of machines made, were used for ploughing, harvesting and fertilising the crops. This made a farmer's job and life a lot easier. Before the machinery was invented, some farms had about 50 people
Globalisation in India
The purpose of this paper is to identify the effects of globalisation on the development policies in India as the nation attempts to embed western style capitalist structure and technologies on to traditional way of life, and to find out how India is responding to these challenges in its drive towards economic development. What is globalisation? Globalisation is the shift toward a more integrated and interdependent world economy. This is largely the result of planning by politicians and business organisations to breakdown borders hampering trade to increase prosperity and interdependent thereby decreasing the chance of future wars. Globalisation is not a new concept, the potential effects of globalization, positive and negative were recognized 150 years ago by the political philosophers Marx and Engels. They did not use the word "globalisation", but their themes and concepts sound remarkably similar to our world in 2008 (Marx and Engels 1996, pp.98-137). The merging of historically distinct and separate national markets into one huge global marketplace, falling barriers to cross-border trade have made it easier to sell internationally. Also the sourcing of goods and services from locations around the globe to take advantage of national differences in the cost and quality of factors of production (such as labour, energy, land and capital). The development of communication
People use the cycle lanes more during weekdays than over the weekends.
Introduction Hypothesis People use the cycle lanes more during weekdays than over the weekends. The following is a fieldwork project looking at the cycle lanes in Broadstone. A cycle lane is a section of the road, which is only allowed to be used by cyclists it can also be a specifically marked path running through the woods. The lanes on the road are divided from the road using a white line; signs usually indicate the beginning and the end of the lanes. The part of the cycle paths that I am concentrating my survey on is part of the Castleman railway (see map on page 1). All around the world people are aware of the fact that pollution from cars, factories and other such man-made machinery, is causing permanent to the planet. Something has to be done to cut down the number of cars and to improve the environment. People nowadays are conscious of the fact tat that as a human race in total, we are becoming much lazier and lacking fitness due to the modern technology that we possess. The growing congestion of vehicles is beginning to become a major dilemma. Organisations, such as Sustrans, are trying to solve these problems by promoting and creating cycle lanes. Sustrans plans to complete a National Cycle Network that will be 7,000 miles long by the year 2005. It will create "safer routes and a healthier environment". But not enough people are moving to this type of transport,
My River Towards Home - Sarah Royce Imitation Paper
My River Towards Home Sarah Royce Imitation Paper At the end of the fourth week of September, 2004, I began my day with a phone call from my mother. Nearly two weeks earlier, I had bidden farewell to my parents and all my friends in Indonesia, and began living in Boston University in Boston, Massachusetts. The morning of the phone call from my mother was not very bright, nor was it very gloomy. We spoke of my well-being, the progress of my classes, and the weather. Although our conversation was engulfed by the sounds of the rain outside, it did not wash away my overwhelming nostalgia, my longing for home. After eighteen prosperous years in my homeland, Indonesia, I had only recently, for the very first time, moved across continents, countries, and miles of distance to my present destination. The journey to a foreign, unfamiliar land had awoken a part of me that was not yet conscious to my senses, a sense of longing and appreciation for home. Had I not made up my mind to encounter many storms in this great transition of my independency? If I had to pursue university, let me go when I please and meet whomever I please, bravely and willingly. These thoughts, with great force, troubled me continuously as I began my new experience away from home. So throughout the minutes of conversing with my mother, I sweetly hid my feelings of distress to appear somewhat merry and content
Hypothesis of Geography Coursework
Hypothesis 3 That people who shop in Cardiff are more satisfied with the facilities available than they are with those in Tredegar I believe that people who shop in Cardiff are more satisfied with the facilities such as cafes, restaurants and parking that are available than the shoppers are with those in Tredegar. I think this because Cardiff is a large city that attracts tourists; it is a centre of commerce and has many shopping complexes. Therefore the local council may have an interest in keeping visitors to the city happy as they bring money into the town which in turn keeps the traders happy as they will make money. To get the shoppers opinions we included a multiple choice question in our questionnaire. The answers ranged from "very satisfied" to "very dissatisfied". We asked shoppers to give their opinions on eight different facilities available in the area. Some of the responses are shown below. LITTER It can be seen from the graph above that 72% of the shoppers questioned in Cardiff were satisfied or very satisfied with how little litter there was. Whereas 74% of the shoppers questioned in Tredegar were dissatisfied or very dissatisfied. I think this is because a lot of the shoppers questioned in Tredegar were residents of the town and would notice the litter more. This may be because they see it everyday or because to them it is their town that people are
