WHAT ENERGY SOURCES SHOULD BE CONSIDERED FOR THE FUTURE?
As we move ahead in time, the population growth rate is increasing at an exponential rate. As a result of this the energy demand is increasing as well. To meet this demand, more and more energy is being generated. Conventional energy sources like natural gas and coal has been the main sources of energy production. At the rate we are going, these sources will be depleted very soon. These sources contribute to a major portion of greenhouse gas (GHG) emissions associated with the power industry. It is about time that everyone start looking towards the sustainable practices or sources that contribute to GHG emission reductions and prevent natural resource depletions. Everyone is now interested in the idea of "Going Green" and this is the right way to go. Residential as well as industrial energy consumers are becoming more and more attracted towards green energy. Energy produced from sources like solar and wind have minimum environmental footprint and these sources do not deplete like conventional sources. With the enactment of facilities like net metering and various tax incentives, people are getting more encouraged towards investing in these sources. CO2 emission related problem is a major culprit for the increasingly degrading air quality and power industry is considered a major culprit for this. In case of United States, Kansas holds the 27th position in terms of CO2 emission by the power industry . Coal has

The rising issue of CO2 emissions in the United States is a problem that we cannot ignore any longer. The main sources of carbon dioxide emissions come from the combustion of fossil fuels such as coal, oil, and natural gas. These emissions also come from everyday use of electricity, transportation and industry. Automobiles, large highways, and leaving your lights in your house on are all everyday examples that emit carbon dioxide. (EPA, "Overview of Greenhouse Gases") Carbon dioxide emissions, which have increased by 7% in the U.S. since 1990, are a dangerous and potent greenhouse gas yielded at a higher rate through coal burning than most other natural gas burning. Increased levels of carbon dioxide can lead to climate change and an increased
The United States is the second largest producer of greenhouse gases in the world, and yet is doing very little to fix this startling statistic (Dennis). The US’ reliance upon outdated energy sources continues to harm both the environment and the economy by producing millions of tonnes of pollution every year and costing the government billions of dollars (“Fact Sheet: Clean Power Plan”). Fossil fuels have been the main energy sources in America since the industrial revolution, and it is time to make a change. Renewable energy is energy harnessed from sources like the sun, wind, or water, and has little to no negative effects on the environment (“Renewable Energy Technology Basics”). The United States needs to integrate and increase the use of these types of energy across the country, as well as implement positive environmental policies, to prevent further pollution of the earth and combat the effects of climate change.
Carbon emissions are changing the planet for the worse. Energy production (mostly coal) is producing a one third of the US 's global warming emissions. Renewable sources produce little to zero percent. The balance of coal and renewable energy in the U.S. needs to be evened out with renewable techniques. Statistics from the Union of Concerned Scientist’s “Benefits of Renewable Energy Use” show that most renewable resources emit less than one pound of CO2E/kWh. These have significantly less of a carbon footprint than coal, which emits 1.4 to 3.6 lbs. CO2E/kWh or natural gas, which emits .6 to 2 lbs. CO2E/kWh. This impressive difference of carbon emissions between renewable and fossil fuel is the key to caring for our environment. A 2009 USC study found that if 25 percent of the US 's
On the same note, the energy revolution spoken of above brings forth another advance in the ongoing global climate situation. The nature of the Kyoto Protocol calls for nations to increase research and eventually semi-convert their energy usage to accommodate for cleaner energy. Products such as solar power, wind power, biomass, geothermal power, and hydropower are now widely being studying to create processes that use less coal, oil, and natural gas in production. Altogether the results have
While this is great to the consumer, the renewable sector’s growth was more stagnant. Attention was diverted to use another greenhouse producing fossil fuel rather than a clean renewable. A trend in U.S. Energy Information Administration’s (2017) data showed renewable sector’s power production since 2008 grew only 5.7% as compared to natural gas production 18%. Another disadvantage to the diversion from renewables is the additional carbon dioxide generated from these additional plants operating. “About 24 percent of U.S. carbon dioxide emissions are related to natural gas in 2011” (Natural gas prices. (n.d.)). The replacement of coal-fired power plants with natural gas has let to a decrease of the green house gases, mainly particulate matter and sulfur dioxide emissions. “Sulfur dioxide (SO2) emissions produced in the generation of electricity at power plants in the United States declined by 73% from 2006 to 2015, a much larger reduction than the 32% decrease in coal-fired electricity generation over that period.” U.S. Energy Information Administration (2017). This shows that more efficient control equipment can be used to almost eliminate the trace amounts of sulfur dioxide in natural gas.
The United States relies heavily on fossil fuels as its main source of energy and with the limited supply, we 'll have to develop and utilize alternative sources for clean, renewable, cheap and effective energy to power this country and the world into the future. It will be important for the health of our planet to utilize renewable resources that have no greenhouse gas emission. Out of necessity the world will eventually need to stop using fossil fuels for energy.
Despite natural gas being cleaner compared to coal, its use still has impacts on the air quality, as well as human health. Besides, its production has enormous environmental consequences in form of habitat destruction. Moreover, the contribution of natural gas production to climate change is just slightly less compared to coal in terms of energy. Furthermore, a decrease in the natural gas reserves has led to doubling of its price. This makes it a more volatile and less attractive alternative for electricity production compared to clean sources such as solar and wind. There is also an opportunity of meeting power generation and heating needs using efficiency measures and renewable energy sources rather than natural gas. As such, Ontario is left with an alternative of considering most efficient and environmental friendly energy sources, which include hydropower, solar, ground heat, biomass, and wind.
Emissions from coal fired power plants contribute to global warming, ozone smog, acid rain, regional haze, and perhaps most consequential of all from a public health standpoint, fine particle pollution.
The world right now is facing a major disaster if our habits don’t change. Fossil fuels dominate our energy demand and at our current rate this will remain true for quite some time. The World Energy outlook claims that by 2030 84% of our energy demands will be fulfilled by fossil fuels (Shafiee et al, 181). It is believed that we possess the reserves to meet our demands until 2030 (Shafiee et al, 181) but the cost will increase as time goes on. Fossil fuels are a non-renewable resource, meaning that once we run out of what’s currently available, we cannot replenish it. Our future energy needs are heavily dependent on a non-renewable and quickly depleting energy source.
The coal industry in the United States has been a substantial job industry in states such as Wyoming, Kentucky, and Ohio providing up to over 76,000 mining careers in 2014 that area essential for the areas surrounding the mines but employment number is less than that of Arby’s, the fast food chain (Ingraham 2017). This size of the career poll brings into question what direction would be most beneficial for the United States in terms of our energy industries and where we should focus our efforts in terms of resources and time. The employment in the coal industry decreases exponentially with time due to the modern technology used to mine coal and decreasing demand. Additionally, coal mining has become
The greenhouse gases produced by the manufacturers, factories, and vehicles all around the world is still very high. And it is not helping our atmosphere. We still trap tons and tons of heat inside this planet and it is causing major changes in different parts of the world. It is melting the ice and causing extremities in weathers. Some people and other species cannot and will not survive in this cycle if this still goes on. An alternative solution? Well there is a lot that we can name. We can stop using fossil fuels such as oils and coals. These are nonrenewable resources. We are going to run out of them soon enough if we keep on relying on them. And if we do run out, then countries will have to wage wars since they are going to fight over those resources. It is as if they are wolves trying to survive in the wild by fighting over a single sheep meat. When there is many still many alternative meat to eat. One great alternative to getting convert into electricity is solar energy. Solar energy is a renewable source since it is an energy acquire with the presence of the sun. This energy also works without the presence of the sun if the energy is stored in a battery for use in the evening. Rural side of California, such as Merced, uses this
As the world population rises, we are using more and more energy and it is depleting faster than ever. Our fossil fuels (coal, oil and natural gas) will not last forever and at some point we will have to switch over completely to renewable energy sources. While most of the world still uses non-renewable energy sources, the future will rely on renewable energy and its applications. Right now, over 90% of the world still uses fossil fuels and developing countries even burn wood to generate energy. At the rate we are using our fossil fuels, they will not last us far into the 22nd century. Additionally, big consumers of fossil fuels like China, U.S., Russia, and India are creating large amounts of pollution and it is only increasing. For instance, India has major issues with pollution because of heavy traffic (which releases more fuel emissions into the air), the burning of biomass (wood and other organic matter), and runoff into lakes and rivers. Right now, our biggest goal should be to figure out how to implement more forms of renewable energy in our own society. We should start using renewable energy in America because: it is more environmentally friendly, opens up the job market, and improves the health of the public.
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
Wind, solar, geothermal, hydroelectric, and biomass provide so much benefit for our climate, health and our economy. As many reliable energy’s rise on demand and expense like oil, coal, natural gas and nonrenewable fossil fuel that draw on limited resources which will eventually diminish. Looking at all the power plants and the millions of cars that exist in the streets today and many more technologies and industries that are polluting the air it is safe to say we may be going the wrong way into saving the world our kids will grow into. People and many utilities need to focus on the positive outcome of renewable energy. Like the good it brings on stable energy price, improvements on public health as well as the prevention of global warming discharge, jobs and other economic benefits.
The most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gas in the atmosphere. These problems drive researchers and societies to search alternative energy such as switching to renewable energy or carbon-free energy to replace fossil fuels. For example Nakata et al., (2011:465) show ‘low-carbon society’
