Types Of Energy Essay Example | Topics and Well Written Essays - 1000 words

Types Of Energy - Essay Example This form of energy is obtained by the conversion of wind energy a utilizable form of energy, for example, making electricity using wind turbines, wind pumps for pumping water, windmills for mechanical power or sails to propel ships. The important features of this form of energy include being clean, plentiful, renewable and zero emission of greenhouse gases (GHGs) when in use. Large-scale production of wind power generation is done in wind farms which consists hundreds of single wind turbines connected to a network of electric power transmission. Its production is influenced by wind distribution in terms of strength and speed. This makes the production of wind power to be limited to certain places that experience winds that are substantially strong to turn turbines. This could be onshore and offshore places. Offshore wind power production involves the construction of wind farms inside in water bodies to generate electricity. Better wind speeds are available in these places compared t o on land/onshore. Some of the largest onshore wind farms are found in the US.Unlike other forms of energy, the production of wind power does take away farms from farm owners and neither does it render the land unusable for other purposes. It is highly compatible with agriculture. According to American Wind Energy Association (2009), landowners in the US receive a rental income of between $3,000 to $5,000 for each wind turbine as they continue to graze cattle or grow crops up to the foot of the turbines. In comparison to fossil fuels and other sources of power, the effects of wind power on the environment are less problematic. Their trends for the production and use of wind power have been rising and as of 2011, a total of 83 countries worldwide are using this form of energy on the commercial basis (REN21, 2011). Despite having lower levels of adverse environmental effects, wind power is not suitable for some places like Pitchandikulam because the area is forested. Trees act as windbreaks and therefore they reduce the speed and strength of the wind. This means that wind blowing over Pitchandikulam does not have sufficient power to turn turbines for generating electricity from wind. Pitchandikulam is also surrounded by other communities belonging to Auroville Green Belt and these communities are also forested and this reduces the power of the wind reaching this place. Pitchandikulam does not have an area with a very high altitude compared to its surrounding areas. This could have enabled it to utilize high-altitude winds for the generation of wind power. Alternatives energy supply or solution for Pitchandikulam which does not have a negative effect on the environment Wind power as a clean source of power could be the most suitable for Pitchandikulam. The alternative energy solutions or supplies for Pitchandikulam that do not have a negative effect on the environment is solar power. Solar power is a form of energy that is obtained from the conversion of sunlight into electricity. This is achieved through the use of various technologies that can be categorized as either active or passive depending on the mechanism through which they capture, convert and

Project Management Essay Example | Topics and Well Written Essays - 750 words - 8

Project Management - Essay Example Some of the cost are administrative, utility bills, etc. this cost are involved in the budget preparation using an agreed rate stating that indirect cost not to exceed a given percentage of the total cost, most project use 15 percent. No, because other costs e.g. taxes and interests that were not involved in execution of the project either directly or indirectly were deducted from the revenue after selling the project. From my point of view the project seems to generate revenue over time as compared to selling it at the completion which will fetch a low price. Average cost of concrete worker per hour (ACW/H) is $ 24.83 (â€Å"Average hourly and weekly earnings of production and nonsupervisory employees on private nonfarm payrolls by industry sector, seasonally adjusted†, n.d.). These overhead charges are the costs that will be incur as the pouring of the reinforced concrete is executed, also referred to as indirect cost. The total estimate cost is $ 67,596. According to (Parker & Isola, 1991) overhead charges charge should not exceed 15% It is very important when a construction project or any other project is being implemented the overhead cost ought to be considered and caution to be taken, so as to prevent budget from being in crisis. Steel is one of the vital components required in reinforcing concrete. When the price of steel increases this has a negative impact to the budget of the project. This normally happens due to inflation or other factors that affect prices in the market. An increase in price will force the project manager to reduce the fund allocated to other activities or to source other funds to overcome the deficit. In budget preparation it is advisable that a 20 percent excess of the actual estimate should be added so as to take care of scenario like this one(Parker & Isola, 1991). Whenever hurricanes occur they cause destruction or
