The significance of energy use and conservation of Environmental Management
INTRODUCTION
Energy flows from many sources, exists in a variety of interchangeable forms, and units of all systems. It is essential to the quality of our lives and now, we are fully dependent on an abundant and continuous supply of energy to live and work. It is without doubt the key ingredient in all sectors of modern economies.
Fossil fuels and nuclear technologies as a principal source of world energy production since the beginning of the decade of 1970, left a legacy of thousands of natural gas thermal power plants and oil spread over the world. Emissions of carbon gases and nuclear non-degradable waste produced by these plants have caused serious environmental problems as global warming leads to a virtual chain reaction of ozone depletion followed by global warming and climate change.
Meeting the energy needs of developing countries in coming decades in a way that promotes economic development and prevent environmental degradation environment is one of the most important challenges in the world. Meeting the energy needs for development in a way that avoids environmental degradation is not only a concern of developing nations, to be feeding, clothing, health care, education, housing and finding jobs for people to exploit. Is also a challenge for developed countries, which suffer from environmental degradation, rising fuel prices, the loss of great potential in countries developing markets, confiscation of the debt, and huge international security costs arising from instability in developing countries, where energy needs to drive development are deeply satisfied.
Environmental management is the field of study that includes the protection, conservation and Sustainable various elements (eg, biodiversity, energy, etc.) or environmental components. Environment includes physical factors of the human environment, including air, land, water, Climate light, sound, taste, smell, microorganisms, biological factors of animals and plants, cultural resources and socio-economic factors aesthetics, and includes both natural and built environment and how they interact.
Energy is the ability of a physical system to do the job. Energy exists in various forms, such as heat, kinetic energy or mechanical energy light, power, electrical, or other forms. There are also two types of energy sources: renewable and nonrenewable. Renewable sources like wind, energy solar and water is constantly renewed. non-renewable sources of energy such as oil, gas and coal can not be replaced and are in limited quantities.
Energy conservation is the reduction in the amount of energy consumed in a process or system, or by an organization or society, through the economy, waste disposal and wise use. Energy conservation can be achieved through more efficient use of energy, related to decreased energy consumption and / or reducing consumption of conventional energy sources. Energy conservation may result in increased financial capital, environmental quality, national security, personal safety and human comfort. Individuals and organizations that are direct consumers of energy choose to conserve energy to reduce energy costs and promote economic security. The industrial and commercial users can increase the energy efficiency to maximize profit. Know the definition of energy conservation is important because it will help save non-renewable energy resources so that they are available for future generations.
Developing countries are countries that behind the level of economic development in the North. They known as the South and are the nations of Latin America, Africa and Asia, except Japan.
Sources of energy in developing countries developing
About half of all people in developing countries depend on fuel wood, dung and crop residues, collectively known as "traditional biomass. Three quarters of them live in China, India and sub-Saharan Africa. The International Energy Agency (IEA) has predicted I use traditional biomass will decrease in many countries, but is likely to increase in South Asia and Africa, along with population growth.
In general, the IEA forecasts that by 2030, the total number of people relying on biomass were not significantly changed. Although the use of sources traditional power is not necessarily desirable in itself, concerns have been raised over how they are currently using.
sources modern energy such as electricity and fuel oil, generally provide only a small part of the energy use of the population rural poor. This is mainly because they are too expensive and because it can be difficult to get a regular supply to isolated rural communities.
Energy Use in developing countries
Developing countries produce 43% of world energy, but they represent only 29% of total energy consumption. However, energy consumption varies greatly between countries. Developing countries in Asia (China, India, Korea, Thailand and Indonesia), for example, consume 60% of energy in the developing world.
However, Third World countries are rapidly increasing energy consumption the 21 st century as they develop their economies. Its consumption of coal, oil, gas and electricity will triple over the next 30 years, according to Agency International Energy Agency (IEA). This growth in energy consumption could seriously affect the environment, not only in developing countries, but at Overall, the IEA warned in its recent report Energy in Developing Countries.
Rapid population growth and accompanying demand for higher living standards are among the factors contributing to increased energy consumption, according to the IEA. In addition, high energy devices consumers have become cheaper and more readily available, making many of the "advantages" of the developed world in the hands of people all the time.
The production of energy needed to meet this growing demand have substantial environmental effects, says the IEA. Although developing countries currently consume proportionately less energy per person than do industrialized countries, its expansion is much faster. Third World participation in the total global emissions of carbon dioxide from burning fossil fuels is projected to increase from 25% today to 44% in 2025. If the impact of tropical deforestation levels of carbon dioxide is taken into account developing countries' participation in the responsibility for global warming is elevated, the IEA says.
Further east, in addition to the burning of fossil fuels, coal mining and the construction of dams, degrade the environment. And the use of biomass, the main source of fuel for much of the Third World, not only contributes to the problem of deforestation, but also produces pollution air.
The magnitude of these problems emphasizes the need for more efficient production, processing, distribution and use of energy, says the report. Improved efficiency would allow countries to meet increasing energy needs of their growing economies without increasing production of environmentally hazardous energy levels. For example, modern kitchen stoves are four times more fuel efficient than traditional stoves, notes IEA. iron plants by the state of the art steel and use half the energy per tonne of crude steel produced as iron inefficient integrated steel plants and operating in China and India.
However, financial constraints prevent households from the purchase of fuel efficient stoves, and industrial users must against outdated machinery and erratic fuel supplies of dubious quality. May be needed even more than new technologies, more efficient is the push policy makers to adopt.
Developing Nations Energy Efficiency
Demand for energy in developing countries development is increasing at a rapid pace and this is a major concern for the world. In order to stimulate economic growth, countries developing countries have been promoting its industrial sector. With the emergence of new enterprises, energy consumption and pollution has been increasing. In these situations, promoting energy efficiency in developing countries has become a major challenge for international organizations.
Several reports of the survey show that almost 50% of total energy consumption in developing countries is the industrial sector of these countries. The rate of primary energy consumption developing countries has increased at an average of 5% per year while in developed countries, this rate is between 0.5% -0.6%. Energy intensity industrial sector is very high, since there are a number of activities related to this sector, ranging from resource extraction to the production of finished products. This diversity of work is the main problem in reducing energy consumption in this sector. More than this, the dilemma facing national governments in these countries in development is that if they reduce energy consumption, industrial sector growth will slow and reduce the rate of economic development and offer no alternative sources consumption of energy such as solar energy, wind energy, nuclear energy and high and costly for them. That's not a politically acceptable in many if not most developing countries.
Another important factor related to energy consumption in developing countries is to population growth. The population growth are very high in several developing countries and with this population growth, demand for new homes, office buildings, electrical etc. the appliances will also increase. With this trend in energy consumption is also expected to increase rapidly.
In such situations, increasing energy efficiency is the most important factor. A large number of international organizations such as UN organizations, World Bank and other alliances want to save energy. These organizations, along with the national government and national organizations in developing countries are resorting to the creation of various strategies to promote energy efficiency in developing countries. These organizations also organize the necessary funds for the purpose through several grants and private investment. At the same time, ESCOs (Energy Service Companies) are also playing an important role in reducing energy consumption in developing countries.
Energy Production and environmental impacts
Energy plays a key role in promoting the transition from traditional to modern society and therefore helps the economic and social development. In turn, this energy is drawn from rural areas, either fossil fuels or renewable energy and can be a significant impact on the rural economy and the environment.
Used wisely, the energy can provide environmental benefits, if misused, can also exact significant environmental costs to land, water and air. Environmental costs of extraction and transportation of energy resources of greatest use in developing countries today are coal, oil, gas, hydropower, biomass and other forms of energy are discussed below.
Coal
Coal has significant effects on the environment throughout the life cycle of the fuel. The environmental effects of coal mining depends on the techniques used. mining methods are selected according to the depth of coal seam thickness, and the availability of capital and equipment. In the area of mining, the topsoil and debris are removed for expose the coal. The mining process can disturb the land surface and water and can contaminate groundwater or distort. increased erosion, downstream sedimentation and water pollution may follow if the excavated material is not handled properly during mining.
resource productivity of soil and water can be broken if the land is not properly recovered. The most severe impacts associated with groundwater mining surface subsidence over mined-out areas, disruption of aquifers and water pollution from acid drainage. In addition, dust and emissions coal mining, preparation and transport or teams can contribute to local air pollution.
Oil and Gas
Oil and gas have similar environmental impacts. During the exploration and production, environmental concerns major alterations in land include land, pollution of the aquifer, leakage and spills, and disposal of liquid and solid wastes. For offshore operations, concerns include the impacts of fishing operations and marine habitats, leaks and spills, and waste disposal.
Large spills of oil or petroleum products, which sometimes occur during production, storage or transport, are perhaps the environmental threat most dramatic related to oil production.
Small leaks and spills are much more common, however, and may have a greater global impact on the environment. Oil spills can poison fish life and aquatic animals and plants. In addition, sediments can trap oil, creating a long-term source of pollution.
Moreover, petroleum refining generates liquid and solid wastes and air emissions. These facilities have requirements for pollution control similar to many other large industrial and chemical plants, but the leakage of toxic compounds are produced, however.
Hydropower
Themajor environmental impacts of hydropower projects large number of initial construction of hydroelectric facilities, complete deposits, and changing river flow. This is in contrast with other sources of energy, so that the main effects extend the fuel cycle. the construction of large dams often requires land clearing for access routes and times for the removal of construction materials with consequent land degradation and erosion. Fill the tank can flood large tracts of land, uprooting people and leads to loss of forests, wildlife habitat and species diversity. For example, the Akosombo Dam on the Volta in Ghana, the land requirement of 8,730 km2, is approaching the size of these small countries such as Lebanon and Cyprus. Some dam projects currently proposed large flooding densely populated valleys and require large-scale resettlement of residents local.
Dams disrupt the natural flow of rivers. Change in flows can erode riverbeds, flood patterns alter, damage aquatic ecosystems, and disrupt spawning and migration patterns of fish and other species. The introduction of a new lake can affect groundwater and streams groundwater and interfere with the necessary flow of nutrients, and can induce microclimatic changes in humidity, cloudiness and precipitation. Furthermore, if the vegetation not deleted from the reservoir area before flooding, decaying organic matter releases large amounts of C02 and methane, two potent greenhouse gases.
Hydropower plants, in turn, are vulnerable to environmental degradation, heavier than expected sedimentation of the reservoir land deforested or degraded upstream can reduce the life of hydroelectric projects.
Although the production of hydroelectric power has many effects on the environment, which offers several advantages;
i) Its relatively cheap compared with other services
ii) is free pollution
iii) There is potentially renewable resource, provided you can stop filling deposits of sediment.
Biomass
BiomassFuels-biomass-wood, waste agricultural and animal manure are the main fuel for people in rural areas, and in many regions of developing countries is also important for the poor urban. Until recently, it was widely believed that many developing countries were on the verge of becoming desert with no trees or mountain plateaus due to demand wood. These predictions are based largely on the "gap" model, which represents a per capita demand for freedom of wood and a growing population and while the forest base is shrinking due to agricultural expansion and overharvesting of forest.
Biomass can be produced on-farm energy and in many cases, the costs to produce bio-energy can be much lower than the world price of oil. bioenergy production is attractive, where unemployment or underemployments are chronic, as large amounts of labor are involved in the cultivation and conversion of biomass. bioenergy can provide decentralized sources of energy, helping to boost rural development in developing countries and to minimize migration to urban areas.
In recent studies, however, has found that the use of fuelwood is very elastic in terms of their availability and labor required to collect or, if have been negotiated price. When the wood is difficult to obtain food, people quickly resort to low quality wood, agricultural residues manure. More generally, the rural subsistence farmers causes relatively little damage to forests, as they often have only dead wood or small branches. They do not have the tools cutting large trees. Much of the wood is collected fromhedgerows or other sources near their farms. In Kenya, For example, trees outside forests provide half the demand for firewood.
In contrast to rural collectors, firewood sold and operations charcoal to supply urban households, commercial facilities and industrial operations often cut whole trees and may damage or destroy areas wooded. Theimpact commercial demand for fuelwood are limited, however, as users will switch to fossil fuels when wood becomes scarce and prices rise. The extent of damage to the forest because of the demand for fuel sold next depends on the distance between the user and the forest, forest size, the size of demand, the rate of re-growth and other factors. The use of biomass as fuel is usually not a cause of deforestation. It does, however, adds additional pressure on forest resources.
In arid or semiarid regions where forest growth is slow and there is a high population density or concentrated urban demand for firewood, as the African Sahel, the use of biomass fuels can contribute significantly to deforestation.
Biomass burning produces large amounts of air pollution in developing countries. The food is usually cooked on open fires or poorly ventilated oven at present women and children and other family members to high levels of toxic smoke. The same Thus, in colder climates, houses in rural areas are often heated by open fires, further increasing exposure to toxic smoke. Impact This indoor air pollution is an exacerbation of one of the deadliest types of infectious diseases, acute respiratory infections in children.
The use of biomass as fuel, forest land clearing for agriculture, grazing and burning to produce forage for livestock, produce large amounts of smoke contributing to regional air pollution.
These activities also pump greenhouse gases into the atmosphere, which could contribute to global climate change.
In fact, Wood is not only one of many forms of biomass that can be used to produce energy. Waste can be incinerated to produce steam heat and electricity. Manure, human waste and other organic waste can be used to produce methane gas. However, all these systems capital needs over production for energy efficiency and therefore developing countries lack the capital so enormous and especially the concentration of wood energy use.
Nuclear Energy
Nuclear power currently accounts for bit to the overall energy requirements of developing countries. Seven developing countries uranium:
South Africa, Niger, Gabon, India, Argentina, Brazil and Pakistan, eight developing countries for operating reactors 1989 and commercial reactors had several more under construction. A total of 28 developing countries for research reactors.
Fuel cycle conventional nuclear includes uranium mining and processing, fuel fabrication, power generation, and disposal of radioactive waste.
Each of these steps has the potential to release different amounts of toxic and / or radioactive materials into the environment. Usually reported form of small losses, but on rare occasions, also led to disasters like Chernobyl. In addition, the option of nuclear energy released little carbon dioxide or other greenhouse gases into the atmosphere, or emit a lot of sulfur dioxide, nitrogen oxides, or other air pollutants. These advantages and disadvantages pose difficult environmental decisions.
Solar, wind, and Other renewables
Solar energy can be used to heat water or dry crop, or can be converted directly into electricity by photovoltaic cells. The winds can be harnessed to pump water or generate electricity. While holding great promise for providing decentralized forms energy to remote areas, so far, these sources provide only small amounts of energy to developing countries.
Energy geothermal, though still a tiny fraction of the total energy supply in developing countries, is being used in several Latin American countries and developing Asian countries and Kenya. The environmental problems associated with geothermal energy production is highly dependent on the geochemical characteristics each specific site and the extent to which good environmental practice is followed.
Potential adverse environmental impacts include the release of gases (in especially CO2), contamination of local aquifers by saline (and sometimes toxic) geothermal fluids into groundwater, land subsidence covering the wells where geothermal fluids have been removed, and the generation of high temperature effluent liquid containing metals and dissolved solids. With proven technologies and economically sound management, however, these potentially adverse impacts can be kept under control.
Energy Conservation in Developing Countries
Because of the limited amount of renewable energy sources on earth (eg oil, coal and natural gas), it is important to maintain our current source or the use of renewable sources for our natural resources resources will be available for future generations. Energy conservation is also important because consumption of nonrenewable resources, impacts to the environment environment, and the high cost to developing countries produce. In particular, the use of fossil fuels contributes to air pollution and water. For example, Carbon dioxide is produced when burning oil, coal and gas power plants, heating systems, and automobile engines. Carbon dioxide in the atmosphere acts as a transparent blanket that contributes to global warming of the earth, or "greenhouse effect." This may warming trend could affect our climate. Potential impacts are a threat to human health, environmental impacts such as rising sea levels that can damage coastal areas, and major changes in vegetation growth patterns that could cause some plant and animal species threatened with extinction. Dioxide Sulfur is also emitted into the air when coal is burned. Sulfur dioxide reacts with water and oxygen in the clouds to form precipitation known as "Acid rain". Acid rain can kill fish and trees and damage buildings and statues of limestone.
Renewable energy use indeed natural resources such as sunlight, wind, tides and geothermal heat, which is naturally replenished. renewable energy technologies ranging from energy solar, wind, hydro and biomass and biofuels for transport. A nonrenewable resource is a natural resource that can not be re-done, re-production or reclaimed at a comparative level of consumption. There is a fixed amount is renewed or is depleted more rapidly than can be done by nature. Fossil fuels (Such as coal, oil and natural gas) and nuclear energy are nonrenewable resources, as they do naturally, never to be at a pace that makes the way the using sustainable materials and consumables to produce electricity.
Energy conservation in developing countries of their task is not easy, its need to introduce technological efficiency, political agreements, aid provision (developed countries) to use alternative energy sources that reduce cost and environmentally friendly, for example, Brazil has the transfer of oil consumption to ethanol, also needs changes in personal behavior that contribute to reduce energy consumption in households. Changing attitudes toward personal use energy consumption is very difficult for most developing countries, because needed awareness and personal involvement as long as most people in developing countries lack knowledge about the effect of energy human health and the environment.
We star in renewable energy technologies, as they may be particularly attractive dispersion 'out network 'applications and therefore represent an important option for rural areas without electricity transmission and distribution infrastructure. To conserve renewable energy in developing countries, is an efficient technology necessary to replace traditional energy consumption and its counterpart did (developed countries). If developed countries are willing to play an important role in helping developing countries, it is doubtful that the same Northern development path should be promoted. For instances of the solar route is especially attractive to many climates in the developing world, where electricity is estimated 2 million people lack. For example, a photovoltaic system installed 80,000 in Kenya over a 10 – period of one year now provide power to more than 1% of the rural population in Kenya. This system, costing between $ 300 to $ 1,500, is successfully marketed to people with average incomes less than $ 100 per month, and the environment.
In fact, energy technology has the greatest potential to immediately improve human health and welfare in many developing countries is relatively simple. Is the improved stove. The use of traditional fuels such as wood and dung for cooking is inefficient and generates levels extremely high indoor pollution. Accelerating the transition to kerosene more expensive but cleaner now, liquefied petroleum gas (LPG) or electric stoves, drastically reduce exposure to unhealthy levels of particulate pollution in many developing countries, in particular women and children. Other sectors that offer great opportunities to reduce levels of emissions of conventional air pollutants and improve public health are Transport production and electricity.
More over, like most developing countries, firewood is the only source of fuel to cook more than one billion people. In fact, 90% of the wood of the world is produced and used in developing countries and these results deforestation consumption environmental damage caused by global warming, we need a solution to this problem, such as the development of a timber that encourage people to land planting trees as cash crops. When people have to pay for firewood, trees become important resources that can be put under the administration local communities or private owners, and sustainable use of forests can produce. Then all the other benefits of goods and services provided by forests maintained or used. In effect, this requires the stimulus of developing countries or NGOs.
Research and funding institutions should be brought to change and emphasis on renewable energy and efficiency measures. They (LDCs) should assist developing countries in establishing regional research and development facility focused on renewable energy and efficiency technologies.
A more sustainable energy policy, the need to improve energy efficiency and to help develop countries to avoid or minimize such consequences. None is easy to implement. All they require the active participation of all sectors of society, including individual consumers and local communities, nongovernmental organizations, private companies and industry, the research community of science and technology, governments, intergovernmental institutions and charitable organizations. Developing countries should take the lead in charting new courses of energy themselves. However, developed countries must be willing to provide support, recognizing that have a vital interest in the outcome. These policy actions include:
• Promote energy efficiency and adopt minimum efficiency standards for buildings, appliances and equipment and vehicles.
• Reform of energy subsidies and re-direct.
• Identify the most promising renewable energy resources and implement policies to promote sustainable development.
• Seek support from developed countries to transfer advanced energy efficient technologies, while building the indigenous human and institutional capacity needed to support energy technologies sustainable.
• Accelerate the diffusion of clean technologies, stoves, cooking affordable.
However, most conservation energy is a function of the behaviors and attitudes of staff and the community is composed of individuals. If we come with good attitudes towards conservation at home waiting, we can succeed. Here, as in steps as follows;
I. It should begin with reduced consumption of energy we use in our daily lives as electricity, fuel and water, it is necessary to conserve water and because the water we have in our homes is the result of purification that also requires energy in some form. Most of us have the bad habit of leaving lights, fans and TV on, even when we are not in the room. So we become a little more attention and care you can save lots of energy.
II. Your refrigerator house has a thermostat controlling the temperature inside her, but then there are the saving of energy or power savings that make it more effective than others. Addition this also look for leaks where outside air can enter the refrigerator, if yes, then try to block the leakage.
III. Then let's go your dishwasher, which waste less energy when it is put into lots of dishes and wash all the dishes that handwashing. But if you try to make two compartments in your sink, so you can wash and clean soap dishes in a compartment full of water that could save a lot of energy.
IV. When you take a bath and water heater need to try to lower the temperature when the thermostat interrupts the electricity supply, so that a higher temperature is not established and electricity supply can be cut at a lower temperature.
V. Here come the washer, which can also be used with caution to save some energy. When you set the machine set to warm, not hot as it takes up more power, but output remains the same.
VI. When you use the heater room to check if the dampers are either not working because the energy absorbers against the heater, therefore, more is required for heating. When the summer season is about using the air conditioner fan mode for the use of electricity is reduced.
- Also can keep the oil, opting for public transport that goes into your car and spend four times more oil than it really needs.
CONCLUSION
The mission of the energy needed to achieve a high standard of living in developing countries while preserving the global environment is formidable. The capital requirements are huge and institutional changes required by all parties involved are considerable. With the proper will, the goals are achievable. The consequences of failure would be much more painful than the costs of implementation.
