“Compare and contrast solar power with coal powered energy”
Energy is an important factor in todays society, it is neccesary to power business, manufacturing and the transportation of goods and services all around the world. Solar powered energy is energy from the sun. This energy can be conerted into different energy like heat and electricity. Heat can be used to heat water or heat spaces, for example heating for houses, buildings or even swimming pools. Solar energy can be converted in two ways, by Photovoltaic or “solar cells” which change sunlight directly into electricity or by concentrating solar power plants which generate electricity by using heat from solar thermal collectors. Coal powered energy has played an important role in

Electricity costs in the United States average 7 cents per kilowatt-hour. A currently inexpensive solar system running at an average of 30% peak capacity due to no sun at night or cloudiness which produces 3 kilowatts will cost $6,552. This system will take about 10 years before it costs less than paying for electricity which has been made from coal. However there are some cases where solar energy makes economic sense. Photovoltaics power remote data storage devices can be highly beneficial where electricity is not available such as poor developing countries. Countries such as Africa use inexpensive solar collection devices for cooking and heating water, special design of new houses and buildings can greatly reduce the cost since much of the house becomes an effective solar collector. At the moment the price of coal is relatively cheap and stable due to easy access and an abundant amount that will last up to 250 years longer. Although solar energy is at disadvantage right now, the availability of “free” sunlight will continue to contribute to the development of new ideas that can make solar power more affordable in the future.
The biggest concern associated with coal energy is the affect it has on the environment. It is a dirty fuel that pollutes the air, water and land. Burning coal releases harmful waste such as carbon dioxide, sulphur dioxide,
It is known as the “dirty fuel” because it causes air pollution. Which harms the environment and human health. Coal releases carbon dioxide, sulfur dioxide, and nitrogen oxide and other pollutants. It causes acid rain, and it destroys forests. Even the U.S. has better regulations than other countries the lack of regulation causes climate change.
Coal is not the most abundant fossil fuel, and should not be used in the future. There are three main reasons for this, the first being that the amount of coal in the world is very close to gone. Every year, humans consume 11 billion tons of coal a year, scientists predict that the coal supply will be gone in the next 50 years (Ecotricity, 2017). Another being that coal not being a major source of energy, it is a dirty and hazardous organic matter. Coal can cause black lung disease for the miners who are harvesting the coal (Chiras, 2016). The last major reason is that burning coal is a major source of pollution for the atmosphere. The impact that coal has on the environment is detrimental. When coal is being mined it is mined by using a technique
The article, “Coal and the Environment”, provides the readers will and understanding of how coal works and also how it is dangerous to our environment. Coal on its own is not dangerous to the environment but once the coal is burned, then pollutants are released into the air causing for less clean air. The government has taken a stand on the industries polluting the air we breathe in everyday with the Clean Air Act and the Clean Water Act. These two acts put restrictions on industries that allow for safer and cleaner air.
The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. When an area is to be mined, topsoil and subsoil are removed from the rock and so is another material, call overburden, to expose the bed of coal. All living plants give solar energy through photosynthesis. When plants die the energy gets out as the plants decay. The whole decaying process gets interrupted which prevents the release of the stored solar energy, then the energy stays locked in the coal. The plant material gets subjected to high temperatures and pressures which causes physical and chemical changes in the vegetation, transforming it into peat and then into coal. The formation of peat is the first step in the geological formation of fossil fuels such as coal. Peat plants is not only the first step for formation but they also capture CO2 itself. There are many effect to the environment when it comes to coal; an example is AMD which stands for Acid mine drainage; it includes the outflow of acidic water from coal mines or metal mines. Mines exposed rocks containing pyrite which reacts to water and air to form acid and dissolved iron and can easily wash into rivers and streams. Coal is a huge impact when it comes to hurting our
While technology has led the world into such an advanced setting with intelligent machinery and automated devices, coal has remained a loyal contributor of the energy needed by these various types of equipment to function properly. Almost half of the electricity in the United States is produced in coal plants where coal is burnt to produce this energy [1]. Both beneficial and detrimental factors come with this alternative source of energy, known by the world for centuries.
Coal releases dozens of hazardous substances that can be harmful to human health. These are just four of the many things that coal releases: Mercury, particulate matter, nitrogen oxides, and sulfur dioxide. Every one of these act on the nervous system to cause loss of intellectual capacity. Exposure to coal dust can lead to black lung disease, or pneumoconiosis, which took the lives of 10,000 miners worldwide over the last decade. Black lung disease is similar to diseases you can get from smoking tobacco for a long period of time. This disease is most common with coal miners, because they are constantly exposed to the dangers coal causes. Coal affects not only the human respiratory system, but also the cardiovascular and nervous system. This
Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.
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.
Unfortunately, there are many disadvantages associated with the combustion of coal energy. For example coal releases a tremendous amount of carbon emissions that negatively contribute to climate change and global warming. Coal burning is considered not environmentally friendly due to the large production of harmful by-products such as nitrogen, carbon dioxide and sulfur dioxide. This pollution can lead to other major problems for example acidic rain, as well as hazardous health risks to our eco-systems. Globally, scientists agree that the release of greenhouse gases are contributing to the earths rise in temperature, which leads to rising sea levels, disappearing glaciers and change in annual weather patterns. The main problem associated with
Coal causes local and state water supplies to become contaminated with acid. This is bad for all the fish. The fish in that water die due to the acid corroding their insides. Also the wildlife that drink that water may not survive. The gases coal gives off are highly polluted and not only that but, sulfur is included with coal and when that sulfur mixes with oxygen it creates sulfur dioxide which destroys the atmosphere and is one of the biggest causes of pollution. Coal also ruins ground and surface water causing permanent damage to local ecosystems that use that water
Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.
For many years, energy has been a need for people everywhere. What has become of the world today is due to the revolution in energy use. There are two types of energy non-renewables and sources-renewables. An example of a non-renewable is coal and it is a great type of fossil fuel the reason being is because it is a reliable source of electricity. Examples of renewables are wind,water and solar power. Renewables can be recovered and reused while on another hand a non-renewables can not be used again. Coal has been used for thousands of years archaeologists discovered that coal was used even in the second and third centuries by the Romans. Solar power is a renewable source since it’s powered by the sun. It can be changed into other forms for example both heat and electricity can come directly from the sun. The sun’s power has been used for a lifetime to heat up our homes, water (to drink and bathe), and our food as well. Both energy sources-coal and solar-are quite reliable resources, and are used very much. As worldwide energy sources, coal and solar power share similarities and differences when it comes to having a huge impact on the environment the world's economic status within how much money we profit from them and human health such as increased lung cancer rates.
With that being said here are some environmental impacts of coal you may not know about. The air pollutants cause acid rain, smog ,respiratory illnesses, cancers and toxins in the environment. Coal miners can get respiratory illnesses from the coal dust while mining. If an abandoned coal mine catches fire it puts tons of mercury into the atmosphere, this happens every year and is responsible for three percent of carbon dioxide emissions globally. The second largest contributor to
Waste Generation: coal-fired power use causes several pollutant emissions in the atmosphere causing global climate change (Weaver, 2008). Also, it has large waste generation, which results in land and water resource depletion because it contaminates the very air and water we use every day. This causes public health and safety as well as animal health and safety (Worldcoal.org, 2016)
In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.
