The Best Essay on Renewable Energy | Energy Management
The United States currently relies heavily on coal, oil, and alternative energy essay intro gas for its energy. Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. Alternative energy essay intro contrast, renewable energy resources- such as wind and solar energy-are constantly replenished and will never run out. Most renewable energy comes either directly or indirectly from the sun.
Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
When this water vapor turns into rain or snow and flows alternative energy essay intro into rivers or streams, its energy can be captured using hydroelectric power. Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals.
The use of biomass for any of these purposes is called bioenergy. Hydrogen also can be found in many organic compounds, as well as water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity. Not all renewable energy resources come from the sun. In fact, alternative energy essay intro, ocean energy comes from a number of sources.
The sun also warms the surface of the ocean more than the ocean depths, creating a temperature difference alternative energy essay intro can be used as an energy source.
All these forms of ocean energy can be used to produce electricity. Do you know what renewable sources of energy are and why we should think of these alternative energy sources?
In the past century, it has been seen that the consumption of non-renewable sources of energy has caused more environmental damage than any other human activity, alternative energy essay intro. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere.
This has in turn led to many problems being faced today such as ozone depletion and global warming. Vehicular pollution has also been a major problem. These sources, such as the sun and wind, can never be exhausted and therefore are called renewable. They cause less emissions and are available locally. Their use can, to a large extent, reduce chemical, radioactive, and thermal pollution.
They stand out as a viable source of clean and limitless energy. These are also known as non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean though biomass, a renewable source, is a major polluter indoors. We know where the non-renewable energies — coal, oil and gas — are alternative energy essay intro and how these fuels are transported, combusted, and the power transmitted throughout the country over the power grid.
Because of its location between the Tropic of Cancer and the Alternative energy essay intro, India has an average annual temperature that ranges from 25°C — This means that India has huge solar potential. Solar energy has several applications; photovoltaic PV cells are placed on the roof top of houses or commercial buildings, and collectors such as mirrors or parabolic dishes that can move and track the sun throughout the day are also used.
This mechanism is being used for concentrated lighting in buildings. Photovoltaic PV cells have a low efficiency factor, yet power generation systems using photovoltaic materials have the advantage of having no moving parts. PV cells find applications in alternative energy essay intro home rooftop systems, community street lights, community water pumping, and areas where the terrain makes it difficult to access the power grid. High efficiency cell with concentrators are being manufactured which can operate with low sunlight intensities.
India has an expanding solar energy sector; 9 solar cell manufactures, 22 PV module manufactures, and 50 PV systems manufacturers.
Therefore, technology resources exist in country and a growing market would lead to job growth in country. By the mid s, the subcontinent was installing more wind generating capacity than North America, Denmark, Britain, and alternative energy essay intro Netherlands.
The ten machines near Okha in the province of Gujarat were some of the first wind turbines installed in India. These meter Vestas wind turbines overlook the Arabian Sea. Now, inthere is an installed capacity of 4, MW; however, ten times that potential, or 46, MW, alternative energy essay intro, exists. vi The capital cost is comparable with conventional power plants. For a wind farm, the capital cost ranges between 4. The essential requirements for establishment of a wind farm of optimal exploitation of the wind are the following:.
Wind energy generation has limitations which will influence the extent and type of role it will ultimately play in overall generation of electricity in India. ii Because winds do not blow strongly enough to produce power all the time.
Therefore, electricity from wind farms must alternative energy essay intro a back-up supply from another source. iv Wind towers and turbine blades are subject to damage from high winds and lighting. Rotating parts, which are located high off the ground can be difficult and expensive to repair, alternative energy essay intro.
v Electricity produced by wind power sometimes fluctuates in voltage and power factor, which can cause difficulties in linking its power to utility system. vii Some environmental groups have complained about aesthetics and avian mortality from wind machines. The hydroelectric power refers to the energy produced from water rainfall flowing into rivers, etc. Consequently, rainfall can be a good indicator to investors looking for a location to implement or build a new hydroelectric power plant in India.
Most hydropower plants are situated in regions of the major rainfall. The most successful forms of biomass are sugar cane bagasse in agriculture, pulp and paper residues in forestry and alternative energy essay intro in livestock residues. It is argued that biomass can directly substitute fossil fuels, as more effective in decreasing atmospheric CO 2 than carbon sequestration in trees.
The Kyoto Protocol encourages further use of biomass energy. Biomass may be used in a number of ways to produce energy. India is very rich in biomass. It has a potential of 19, alternative energy essay intro, MW 3,MW from bagasse based cogeneration and 16, MW from surplus biomass.
Currently, India has MW commissioned and MW under construction. The facts reinforce the idea of a commitment by India to develop these resources of power production. Renewable energy technologies alternative energy essay intro clean sources of energy that have a much lower environmental impact than conventional energy technologies.
Renewable energy will not run out. Other sources of energy are finite and will someday be depleted. Most renewable energy investments are spent on materials and workmanship to build and maintain the facilities, alternative energy essay intro, rather than on costly energy imports. Renewable energy investments are usually spent within the United States, frequently in the same state, alternative energy essay intro often in the same town.
This means your energy dollars stay home to create jobs and fuel local economies, rather than going overseas. Meanwhile, renewable energy technologies developed and built in the United States are being sold overseas, providing a boost to the U. trade deficit.
After the oil supply disruptions of the early s, our nation has increased its dependence on foreign oil supplies instead of decreasing it. This increased dependence impacts more than just our national energy policy. From tothere was 3, MW of renewable grid-tied power planned, but the actual capacity addition exceeded 6, MW by A large share of this was the result of exceptional growth of wind energy in India.
Wind energy is expected to add more than 10, MW of additional capacity byfollowed by small hydro 1, MWco-generation 1, MW and biomass MW.
In the past five years, the government of India had withdrawn subsidies for grid-tied solar power because its costs were not considered viable. Plans for a MW Integrated Solar Combined Cycle plant at Mathania, Rajasthan were cancelled after an unfavorable technical and commercial review.
But recently this alternative energy essay intro has experienced a turn-around, alternative energy essay intro, with new technologies and manufacturing capacity in India See Scaling up Solar in India, alternative energy essay intro.
With the success of grid-tied solar electricity in other countries, and new state-level initiatives for feed-in tariffs, the outlook for this segment is now positive. Financial assistance is available in various forms, such as direct installation subsidy, feed-in tariffs, tax rebates, and low interest loans. Increasingly Indians are seeing a shift away from subsidizing installed capacity and towards subsidizing power generation with feed-in tariffs and tax rebates.
Preferential tariffs are being worked out at the state level. While the new framework for supporting renewable energy generation is evolving, most of the direct subsidy has thus far been designed for installed capacity. Some of the highest direct subsidy rates have been announced for alternative energy essay intro of grid-tied wind and small hydro, alternative energy essay intro, and off-grid solar photovoltaic PV projects.
See the chart below for more information. Subsidy support is for firms with majority Indian stake. In the past a significant proportion of allocated funds have gone underutilized, alternative energy essay intro, possibly due to lack of availability of suitable projects and procedural delays. One area of concern is the lack of bankable projects in bagasse-based cogeneration and urban waste-to-energy space. With maturing technologies and integrated business models in renewable energy business, the suitability of projects is likely to improve, resulting in higher utilization of available government funds and faster market growth.
This has been the case of wind energy in India. Integrated installation, operations and repair contracts are common in the wind energy business. This has provided a viable and investor-friendly business model.
Thin-film solar production is alternative energy essay intro to lead to the development of PV-based electricity generation. Technologies in the wind, bio-mass, waste-to-energy and small hydro markets are at the venture capitalist stage, waiting for funding to begin commercialization and scaling up of their projects. Policies at state and local levels, like feed-in tariffs, alternative energy essay intro, tax incentives, technical training, financing mechanisms and revenue recovery can go a long way in building a successful renewable energy market in India.
Improvements in energy efficiency can reduce recurring cost of energy using technology that is often priced even higher than the cost of renewable energy. This will make investments in this sector attractive. Building renewable energy infrastructure also requires mapping the natural resource base. In a continuing effort to build the information infrastructure for renewable energy, GIS geographic information systems mapping of renewable sources will continue with government funding.
