No More Consumption of Coal After the industrial revolution, energy is urgently needed for both daily life and industries. For hundreds of years, human beings have relied on the consumption of energy. People not only cannot live without them but also have to increase the amount for their better living methods and better life quality. Problems come along with increasing energy, especially when the major part of the energy comes from burning coal. Pollution caused by excess burning of coal and trade problems caused by coal prices and coal reserves are so apparent that need to be addressed. However, the advantages of burning coal for energies are so clear for its cheaper

What’s more, if this 40% of energy comes from solar energy instead of burning coal, the cost of transportation and the excess emission of carbon dioxide can be left out.
Moving water can generate energy, which is called the hydropower. Hydropower is a main renewable energy which produces 20% of the total electricity-generation in the world. It is also a green energy which will not emit carbon dioxide. If hydropower is used in appropriate way, it can be considered an unlimited energy. Unlike nuclear energy or solar energy, humans have used water as energy for a long time (Ngo and Natowitz, 121). The technologies are sophisticated and worth spread worldwide. Besides the renewable energy and new energy mentioned above, wind power and geothermal power are also contributing to a healthy energy market. Germany generates their energy by not only solar energy and hydropower but also wind power and geothermal power which are much cleaner for environmental and human health.
The renewable energy and new energy mentioned above like nuclear power, solar power, hydropower, wind power, and geothermal power can help restrict the consumption of coal for their ability of being re-generated which is the biggest advantage comparing with coal. No matter for current or future generations, finite resources not only limits development but also has impact on human survivals. It can be a good method for the
The pollution is leaving our footprint rate out of control! Knowing that they have gotten rid of all the coal generators is a big reduction of the ecological footprint. Without the generators burning off the coal, the pollution will stay at a lower rate causing the footprint to decrease. It is more sustainable now than before because our city doesn't have to worry about trying to maintain the pollution levels as much as we used to and we can focus on more of the major projects.
As the time goes on and the world population grows, our nonrenewable resources will become less prevalent. Coal powers a large portion of the world’s electricity. As the population increases, so will the level of electricity needed. When coal burns it pollutes the air, causing climate change. Mining coal can destroy the natural environment around the mines.
We should invest in cleaner alternatives that will not only be better for us but the environment. Although coal is used for electricity, there are other ways to produce electricity like water power, wind generators, and solar energy. Water power, or hydropower is power that is derived from the weight of the water. Hydroelectric power plants use dams or rivers to store water to then release the water through turbines that spin it that produces electricity. Wind generators are like water power but instead of water its wind. Wind turbines converts the wind’s energy into electric energy. Solar energy is similar but the energy comes from the sun. Some people use solar energy for their homes so they save money and will not have to pay an electric bill. Instead of burning coal, there are other alternatives as stated
CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the
As we go throughout life, we use various kinds of energy sources for our needs. Whether it be from solar energy to wind energy, there is a multitude of sources that allow us to do the things we do each and every day. Throughout the world, however, coal and nuclear power have risen to the
Coal power is the cheapest fuel to power the ever growing population with Australian mining industry still putting in billions of dollars into a vast amount of coal projects never the less coal power is a fossil fuel, a fuel which takes hundreds of year to form so the future of coal is undetermined. Coal is a reliable power source but one of the many concern with coal is the mining process used to remove it from the ground. Ecological effects are developing worries for the industry, with the carbon emissions possibly contributing to global warming.
Coal has been the backbone of American electricity generation for decades. This is a result of it being reliable, affordable, and abundant. Many of those in opposition of coal use in the U.S., and globally, point at the environmental impacts that coal has. But new innovations in clean coal technology has made coal substantially cleaner, and noticeably more environmentally friendly. On top of its lack of large downsides, without the use of coal, the U.S. would suffer an uncompensatable 40% loss in electricity generation.
One of these concerns is that the cost transitioning to clean energy would be too expensive. It is true that shifting to green energy would have notable start-up costs; however, generating energy from these
Coal is considered a fossil fuel great in number but is bad to the environment. This fossil fuel is one of the well-known use in this work. It’s very cheap and its reserves are large. Coal is widely distributed. The united states have over a quarter of the world reserves.
Humans have made significant discoveries in utilizing the countless benefits of water, one of the most important being the ability to use water to perform work. This is the concept of hydropower. Hydropower is using the energy of moving water to create power. This clean and renewable method of power generation is used all throughout the globe, and accounts for a small percentage of global electricity demand. Hydropower hasn’t always existed as the large scale dams that are abundant today. Hydropower technologies have been slowly evolving for many centuries.
The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could
Hydroelectric is a form of energy it is a renewable resource. Hydroelectricity is the most important and widely used renewable source of energy. Hydroelectric relies on water, which is clean and renewable energy source. Renewable energy comes from natural resources. Non-Renewable energy source includes coal, oil and natural gas. Water is renewable because water continually recycles itself. To harness energy from flowing water, the water must be controlled; a large reservoir is created, usually by damming a river to create an artificial lake or reservoir. Water is channeled through tunnels in the dam. The energy of water flowing through the dam causes the turbines to turn and make the
Firstly, and put very simply, fossil fuels are non-renewable! Once the finite deposits of brown and black coal are exhausted around the planet there will be no more energy generated by this process. Current estimates predict that all known coal deposits will be exhausted within the next 120 years.
Power plants are stations that burn fossil fuels such as coal to generate electricity. The burning of coal is used to heat water until it forms into high pressure steam that turns turbines to generate electricity. The burning of coal in the power station is incomplete and produces toxic gases that have negative effects on humans and the environment. This essay will discuss the advantages and disadvantages of using coal
It is the most important and abundant fossil fuel in India. It accounts for 55% of the country 's energy need. The country 's industrial heritage has been built upon indigenous coal. Commercial primary energy consumption in India has grown by about 700% in the last four decades. Considering the limited reserve potentiality of petroleum & natural gas, eco-conservation restriction on hydro projects and geo-political perception of nuclear power, coal will continue to occupy centre-stage of India 's energy. With hard coal reserves around 246 billion tonnes, of which 92 billion tonnes are proven, Indian coal offers a unique eco-friendly
