28 peer-reviewed research has generally not supported these claims. 29 Aesthetic aspects of wind turbines and resulting changes of the visual landscape are significant. 30 Conflicts arise especially in scenic and heritage protected landscapes. Geothermal power edit main article: Environmental impact of geothermal power Mitigation edit Energy conservation edit main article: Energy conservation Energy conservation refers to efforts made to reduce energy consumption. Energy conservation can be achieved through increased efficient energy use, in conjunction with decreased energy consumption and/or reduced consumption from conventional energy sources. Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and human comfort. Citation needed Individuals and organizations that are direct consumers of energy choose to conserve energy to reduce energy costs and promote economic security. Industrial and commercial users can increase energy use efficiency to maximize profit. Energy policy edit main article: Energy policy Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy production, distribution and consumption. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques.

According to the ipcc, in assessments of the life-cycle global warming potential of energy sources, wind turbines have a median value of between 12 and 11 ( g CO2 eq / kWh ) depending, respectively, on if offshore or onshore turbines are being assessed. 23 24 Compared with other low carbon power sources, wind turbines have some of the lowest global warming potential per unit of electrical energy generated. 25 While a wind farm may cover a large area of land, many land uses such as agriculture are compatible with it, as only small areas of turbine foundations and infrastructure are made unavailable for use. 26 27 There are reports of bird and bat mortality at wind turbines as there slogan are around other artificial structures. The scale of the ecological impact may or may not be significant, depending on specific circumstances. Prevention and mitigation of wildlife fatalities, and protection of peat bogs, affect the siting and operation of wind turbines. There are anecdotal reports of negative health effects from noise on people who live very close to wind turbines.

The public is sensitive to these risks and there has been considerable public opposition to nuclear power. Despite this potential for disaster, normal fossil fuel related pollution is still considerably more harmful than any previous nuclear disaster. The 1979 Three mile Island accident and 1986 Chernobyl disaster, along with high construction costs, ended the rapid growth of global nuclear power capacity. 22 A further disastrous release of radioactive materials followed the 2011 Japanese tsunami which damaged the fukushima i nuclear Power Plant, resulting in hydrogen gas explosions and partial meltdowns classified as a level 7 event. The large-scale release of radioactivity resulted in people being evacuated from a 20 km exclusion zone set up around the power plant, similar to the 30 km radius Chernobyl Exclusion Zone still in effect. Wind power edit main article: Environmental impact of wind power livestock grazing near a wind turbine. The environmental impact of wind power when compared to the environmental impacts of fossil fuels, is relatively minor.

Editorializing When the environment gets polluted, not only do humans get forced to live with it, but the rest of the species on Earth must live with it also. 21 Reservoirs edit main article: Environmental impact of reservoirs The environmental assignment impact of reservoirs is coming under ever increasing scrutiny as the world demand for water and energy increases and the number and size of reservoirs increases. Dams and the reservoirs can be used to supply drinking water, generate hydroelectric power, increasing the water supply for irrigation, provide recreational opportunities and for flood control. However, adverse environmental and sociological impacts have also been identified during and after many reservoir constructions. Whether reservoir projects are ultimately beneficial or detrimental—to both the environment and surrounding human populations— has been debated since the 1960s and probably long before that.

In 1960 the construction of Llyn Celyn and the flooding of Capel Celyn provoked political uproar which continues to this day. More recently, the construction of Three gorges Dam and other similar projects throughout Asia, africa and Latin America have generated considerable environmental and political debate. Nuclear power edit main article: Environmental impact of nuclear power Nuclear power activities involving the environment; mining, enrichment, generation and geological disposal. The environmental impact of nuclear power results from the nuclear fuel cycle, operation, and the effects of nuclear accidents. The routine health risks and greenhouse gas emissions from nuclear fission power are smaller than those associated with coal, oil and gas. However, there is a "catastrophic risk" potential if containment fails, 22 which in nuclear reactors can be brought about by over-heated fuels melting and releasing large quantities of fission products into the environment. The most long-lived radioactive wastes, including spent nuclear fuel, must be contained and isolated from humans and the environment for hundreds of thousands of years.

According to the ipcc fourth Assessment Report, 20 in 2004 natural gas produced about 5,300 Mt/yr of CO2 emissions, while coal and oil produced 10,600 and 10,200 respectively (Figure.4 but by 2030, according to an updated version of the sres b2 emissions scenario, natural. ( Total global emissions for 2004 were estimated at over 27,200.) In addition, natural gas itself is a greenhouse gas far more potent than carbon dioxide when released into the atmosphere but is released in smaller amounts. Electricity generation edit main article: Environmental impact of electricity generation The environmental impact of electricity generation is significant because modern society uses large amounts of electrical power. This power is normally generated at power plants that convert some other kind of energy into electrical power. Each such system has advantages and disadvantages, but many of them pose environmental concerns. Current Technology technological advancement will cause those working with fossil fuels, need to further educate themselves, in order to stay in the energy field.

The main advanced technologies are hydrogen fuel cells, solar cells, and wind turbines. Some good companies to work for might be tesla, toyota, solar City, and Solar roadways. Editorializing The future generations deserve to live in a clean environment, so this is a good transition. Vehicle exhaust using combustion engines, is toxic. Why do humans still fill the air with this toxic substances when there are great alternatives? Editorializing humans do not need fossil fuels to survive as a species, but water and oxygen are necessities of life.

Coal edit main article: Environmental impact of the coal industry The environmental impact of coal mining and burning is diverse. 18 Legislation passed by the. Congress in 1990 required the United States Environmental Protection Agency (EPA) to issue a plan to alleviate toxic pollution from coal-fired power plants. After delay and litigation, the epa now has a court-imposed deadline of March 16, 2011, to issue its report. Petroleum edit main article: Environmental impact of the petroleum industry The environmental impact of petroleum is often negative because it is toxic to almost all forms of life. The possibility of climate change exists. Petroleum, commonly referred to as oil, is closely linked to virtually all aspects of present society, especially for transportation and heating for both homes and for commercial activities. Gas edit natural gas is often described as the cleanest fossil fuel, producing less carbon dioxide per joule delivered than either coal or oil., 19 and far fewer pollutants than other fossil fuels. However, in absolute terms it does contribute substantially to global carbon emissions, and this contribution is projected to grow.

According to essay the. The African continent is losing forest twice as fast as the rest of the world. "Once upon a time, africa boasted seven million square kilometers of forest but a third of that has been lost, most of it to charcoal." 15 Fossil fuel use edit Global fossil carbon emission by fuel type,. The three fossil fuel types are coal, petroleum and natural gas. It was estimated by the Energy Information Administration that in 2006 primary sources of energy consisted of petroleum.8, coal.6, natural gas.9, amounting to an 86 share for fossil fuels in primary energy production in the world. 16 In 2013 the burning of fossil fuels produced around 32 billion tonnes (32 gigatonnes ) of carbon dioxide and additional air pollution. This caused negative externalities.9 trillion due to global warming and health problems ( 150 /ton carbon dioxide). 17 Carbon dioxide is one of the greenhouse gases that enhances radiative forcing and contributes to global warming, causing the average surface temperature of the earth to rise in response, which climate scientists agree will cause major adverse effects.

1995 to 2005 found that the cost of producing electricity from coal or oil would double over its present value, and the cost of electricity production from gas would increase by. It was estimated in the study that these external, downstream, fossil fuel costs amount up to 1-2 of the eus entire Gross Domestic Product (GDP), and this was before the external cost of global warming from these sources was even included. 12 The study also found that the environmental and health costs of nuclear power, per unit of energy delivered, was.0019/kWh, which was found to be lower than that of many renewable sources including that caused by biomass and photovoltaic solar panels, and was thirty. 13 biofuel use edit further information: Environmental impact of biofuels biofuel is defined as solid, liquid or gaseous fuel obtained from relatively recently lifeless or living biological material and is different from fossil fuels, which are derived from long-dead biological material. Various plants and plant-derived materials are used for biofuel manufacturing. Bio-diesel edit main article: Environmental effects of biodiesel see also: Indirect land use change impacts of biofuels and Sustainable biofuel High use of bio-diesel leads to land use changes including deforestation. 14 Firewood edit Unsustainable firewood harvesting can lead to loss of biodiversity and erosion due to loss of forest cover. An example of this is a 40-year study done by the University of leeds of African forests, which account for a third of the world's total tropical forest which demonstrates that Africa is a significant carbon sink. A climate change expert, lee white states that "To get an idea of the value of the sink, the removal of nearly 5 billion tonnes of carbon dioxide from the atmosphere by intact tropical forests is at issue.

3, in recent years there has been a trend towards the increased commercialization of various renewable energy sources. Rapidly advancing technologies can potentially achieve a transition of energy generation, water and waste management, and food production towards better environmental and energy usage practices using methods of systems ecology and industrial ecology. 4 5, contents, climate change edit, global mean surface temperature anomaly relative to 19611990. Main article: Attribution of recent climate change, the scientific consensus on global warming and climate change is that it is caused by anthropogenic greenhouse gas emissions, the majority of which comes from burning fossil fuels with deforestation and some agricultural practices being also major contributors. A 2013 study showed that two thirds of the industrial greenhouse gas emissions are due to the fossil-fuel (and cement) production of just ninety companies around the world (between 17, with half emitted since 1986). 7 8, although short there is a highly publicized denial of climate change, the vast majority of scientists working in climatology accept that it is due to human activity. Ipcc report, climate Change 2007: Climate Change Impacts, Adaptation and Vulnerability predicts that climate change will cause shortages of food and water and increased risk of flooding that will affect billions of people, particularly those living in poverty. 9 One measurement of greenhouse gas related and other Externality comparisons between energy sources can be found in the ExternE project by the paul Scherrer Institut and the University of Stuttgart which was funded by the european Commission.
