Advantages And Disadvantages Of Wind Energy - 939 Words

What are the advantages and disadvantages of wind energy? Wind energy as a kind of environmentally-friendly energy, the demand of it steadily increases around the world with population growth and development of technology. Even though wind energy does not produce pollutants like other fuel based energy and it has many advantages, the disadvantages of wind energy should be given attention. As Congressional Digest (2013), a scholarly independent monthly publication, stated that wind is a form of solar energy. The generation of wind results from the uneven heat of the atmosphere by the sun, the irregular surface of the the earth, the earth rotation. Wind flow patterns can be influenced by the altitude, quantities of water, and vegetative†¦show more content†¦For coal power plants, water is also used to clean fuel. By developing the use of wind energy, water can be preserved and used for other purposes. Besides, Wind energy may help to reduce the production of air pollutants by replacing the current sources of conventional energy. (Saidur et. al., 2011) It does not generate carbon dioxide, sulfur dioxide, mercury or any other air pollutants. The data from German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety showed that approximately 67 million tonnes of carbon dioxide was avoided in a year by producing electricity through wind, biom ass, photovoltacis and hydropowe. Among there few types of electricity generation systems,wind energy play the most important role. Wind energy is easily available around the world. Thus, many countries have access to produce wind energy. What’s more, wind turbines are generally constructed on rural areas. Yusuf Alfer Kaplan, a professor in the University of Anadolu, Department of Electrical Electronics Engineering pointed out that the economies in rural communities can be improved by wind energy. Wind energy projects provide new short and long term jobs opportunities to people in rural communities relate to manufacturing, transportation, project construction, and plant maintenance (2015). Besides the advantages, it is important to consider the negative impact of wind turbines technology.

Impact Of Globalization On Politics And Public Policy

Globalization greatly expands in 1990s when it is the period of business establishments nationwide (Naime, 2009). This phenomenon allows economic and politics of one country penetrate others (Mittelman, 1997). In addition, the factors of globalization includes the spatial reorganization of production, the industrialization across borders, the expansion of financial markets, the diffusion of identical consumer goods to distant countries, massive transfers of population and emerging worldwide preference for democracy (Mittelman, 1997). It can be seen that democratizing countries have gained ability in economic improvement in the era of globalization. In fact, democratization emphasizes broad and inclusive citizenship where all citizens have equal rights in political system (Linz and Stepan, 1996). As a consequence, democratization enhances people to participate and attend to choose political leaders to develop their countries. According to Rudra’s research (2005), the significan ce of globalization is bringing about changes in politics and public policy in democratizing countries. In recent era, globalization creates new wave of political economy in transforming modernity and international markets.

Environment and Phenotype Free Essays

The environment can affect the degree to which a gene may be expressed In an Individual. For example, solo type and weather conditions may affect plant growth. Seeds deliver energy for germination and Minimal growth until plants begin to photosynthesis and create their own glucose for further development. We will write a custom essay sample on Environment and Phenotype or any similar topic only for you Order Now Aim/Purpose To demonstrate the effect of environment on phenotype to formulate a hypothesis about the effect of environment on phenotype To design and conduct a controlled experiment to demonstrate the effect of one environmental factor on a plant phenotype. Hypothesis- Radish plants that is grown in sunlight, room light and in the shade where there is absence of light, those that in the shade will display isolating where there Is pale stems and leaves, elongated stems and leaves reducing In size whilst those grown In light will be green, sturdier and shorter. The plants that are grown in the room light will be In the middle of the other two (light and dark). Apparatus and materials- 6 plant pots Beaker to measure amounts of water for the watering of plants Pack of radish seeds 30 CM ruler that has mm written as well 3 trays Soil enough for 6 pots Risk Assessment- The bean seedlings may have contagious diseases. Therefore gloves should be worn. Leather shoes is most recommended to be worn as handling glass may break and water might make you slip Method/Procedure- 1. Put solo Into each of the pots up to where the crease Is, making sure It Is even In all pots 2. Plant seeds by following Instructions on the back of the packet 3. Germinate radish seeds with equal amounts 4. Two seedlings were left as a control: it was watered and taken care of normally under shade. 5. The other four seedlings were placed in either light covered area, or one in dark covered area 6. Water occasionally and wait for observable phonological results. Note Don’t overflow the pots with water Just till moist. 7. Take notes of Plant growth and observations seen. Keep a record of all data being done Results- Observations: Dates: Task: 27. 2. 14 Germination of plants 13. 14 Watered: mall 11 . 3. 14 Watered: mall 14. 3. 14 Measured/taken pictures 18. 3. 14 Light: Stems turning purple starting from the bottom to the top of the stem Leaves vibrant green Thicker stems Control Pale looking Control g’s stem from the bottom is more thicker than control 1 Control 2 is more shriveled up while control 1 is still slightly straight Leaves have shrunk Dark Stem of dark 2 is more of white than dark 2 where it is like a pale green/grey Discussion- *trends happening Conclusion- The phenotype expressed in the light ones display green pigment for the environment influenced the need of chlorophyll for photosynthesis. The ones in the dark turned albino, in the absence of light, photosynthesis cannot take place. When these albino plants were put in the sun, over the course of 2 days they altered to a green color again. From Day 7 to Day 10 plants raised in shade displayed isolating whereas those raised in light did not Observations of plants grown in each There were some factors that have affected some of the result of the experiment. The position of the plants should have been closer together not that far apart. The plants placed in the dark under the bench were the furthest from where the plants in the light and room light were assigned. The amount of water being put in the pots and the consistent watering made the trays flood with water making the pots more than Just moist. The water in the trays wasn’t emptied so it was there for quite a while and was it got emptied a bit later on in the experiment. The dependent variables in the experiment were the growth and the progress of the Lana and this depends on the amount of water, amount of sunlight being taken into place. The control that was kept the same for each plant was the amount of water being put into the pots. The accuracy of the experiment wasn’t to professional expectations but it was taken into considerations of the factors that can affect it. There could be more to make this experiment better and also with the results that were taken. The reliability of the experiment was reliable as it was compared to another student’s similar works done in their time in year 12. But what could have made it more liable is that the experiment could have been repeated another time since the plants start sprouting after 5-7 days after being planted. The plants in sunlight grew normally but those of the same species grown in the dark where there is absence of light elongated much faster to increase their chance of finding light. They were pale in color due to the lack of chlorophyll. The plants that were place in the normal room light grew but the stem wasn’t as thick as the one in the light. The energy reserves of the seed were used up therefore it leads to the plant dying in comparison to the one exposed to light. Other factors in the environment, such as salinity and pH of soil, also affect the phenotype of a plant that would otherwise appear normal. The aim/purpose and the hypothesis were met and the results were similar. â€Å"Radish plants that is grown in sunlight, room light and in the shade where there is absence of light, those that in the shade will display isolating where there is pale stems and leaves, elongated stems and leaves reducing in size whilst those grown in light will be green, sturdier and shorter.
