Duke Energy Coal

Duke Energy is an electric utility company based in Charlotte, North Carolina. It is one of the largest electric power holding companies in the United States. Duke Energy generates electricity from a variety of sources, including coal, natural gas, nuclear power, and renewable energy sources like solar and wind.

Coal is a fossil fuel that is used to generate electricity. When coal is burned, it releases energy that can be used to turn a turbine and generate electricity. Coal is a relatively inexpensive fuel source, but it is also a major source of air pollution. Duke Energy has been working to reduce its reliance on coal and transition to cleaner energy sources.

In 2020, Duke Energy announced plans to close all of its coal-fired power plants by 2035. This is a significant step in the company's efforts to reduce its carbon emissions and transition to a clean energy future.

1. Fossil fuel

Fossil fuels are a major source of energy for Duke Energy. Coal is the most abundant fossil fuel in the United States, and it is used to generate about 20% of the electricity in the country. Duke Energy operates 14 coal-fired power plants in the Carolinas and Midwest. These plants generate about half of the company's electricity.

• Formation
  Coal is formed from the remains of ancient plants and animals that lived millions of years ago. These plants and animals died and were buried under layers of sediment. Over time, the heat and pressure of the sediment turned the remains into coal.
• Composition
  Coal is composed primarily of carbon, hydrogen, and oxygen. It also contains small amounts of nitrogen, sulfur, and other elements.
• Energy content
  Coal has a high energy content, which means that it can be used to generate a lot of electricity. However, coal is also a dirty fuel, and it produces air pollution and greenhouse gases when it is burned.
• Environmental impact
  The burning of coal releases air pollution, including sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants can cause respiratory problems, heart disease, and other health problems. Coal mining can also damage the environment, and it can lead to water pollution and land degradation.

Duke Energy is working to reduce its reliance on coal and transition to cleaner energy sources. The company has announced plans to close all of its coal-fired power plants by 2035.

2. Electricity generation

Coal is a major source of electricity generation for Duke Energy. The company operates 14 coal-fired power plants in the Carolinas and Midwest, which generate about half of the company's electricity.

• Components

  A coal-fired power plant consists of a boiler, a turbine, and a generator. The boiler burns coal to heat water and create steam. The steam then turns the turbine, which generates electricity.

• Process

  The process of generating electricity from coal begins with mining the coal. The coal is then transported to the power plant, where it is crushed and burned in the boiler. The heat from the burning coal turns water into steam, which is then used to turn the turbine. The turbine generates electricity, which is then sent out to homes and businesses.

• Efficiency

  Coal-fired power plants are not very efficient. Only about 30% of the energy in coal is converted into electricity. The rest of the energy is lost as heat.

• Environmental impact

  Coal-fired power plants are a major source of air pollution. They emit sulfur dioxide, nitrogen oxides, and particulate matter, which can cause respiratory problems, heart disease, and other health problems. Coal mining can also damage the environment, and it can lead to water pollution and land degradation.

Duke Energy is working to reduce its reliance on coal and transition to cleaner energy sources. The company has announced plans to close all of its coal-fired power plants by 2035.

3. Air pollution

Coal-fired power plants are a major source of air pollution. They emit sulfur dioxide, nitrogen oxides, and particulate matter, which can cause respiratory problems, heart disease, and other health problems. Duke Energy operates 14 coal-fired power plants in the Carolinas and Midwest, which generate about half of the company's electricity. As a result, Duke Energy is a major contributor to air pollution in these regions.

• Sulfur dioxide
  

  Sulfur dioxide is a gas that is released when coal is burned. It can cause respiratory problems, such as asthma and bronchitis. Sulfur dioxide can also contribute to the formation of acid rain, which can damage forests and lakes.

• Nitrogen oxides
  

  Nitrogen oxides are gases that are released when coal is burned. They can cause respiratory problems, such as asthma and bronchitis. Nitrogen oxides can also contribute to the formation of smog, which can irritate the eyes, nose, and throat.

• Particulate matter
  

  Particulate matter is a type of air pollution that consists of small particles of dust, soot, and other substances. Particulate matter can cause respiratory problems, such as asthma and bronchitis. It can also contribute to the development of heart disease and cancer.

Duke Energy is working to reduce its air pollution emissions. The company has installed pollution control equipment at its coal-fired power plants, and it is working to transition to cleaner energy sources. However, Duke Energy's coal-fired power plants will continue to be a major source of air pollution until they are closed.

4. Greenhouse gas emissions

Greenhouse gas emissions from coal-fired power plants are a major contributor to climate change. When coal is burned, it releases carbon dioxide, methane, and nitrous oxide into the atmosphere. These gases trap heat and cause the planet to warm.

• Carbon dioxide
  

  Carbon dioxide is the most significant greenhouse gas emitted by coal-fired power plants. It is a colorless, odorless gas that is produced when coal is burned. Carbon dioxide traps heat in the atmosphere, causing the planet to warm.

• Methane
  

  Methane is a greenhouse gas that is about 25 times more potent than carbon dioxide. It is produced when coal is mined and transported. Methane can also leak from coal-fired power plants.

• Nitrous oxide
  

  Nitrous oxide is a greenhouse gas that is about 298 times more potent than carbon dioxide. It is produced when coal is burned. Nitrous oxide can also contribute to the formation of smog.

Duke Energy is working to reduce its greenhouse gas emissions. The company has announced plans to close all of its coal-fired power plants by 2035. Duke Energy is also investing in renewable energy sources, such as solar and wind power.

5. Transition to clean energy

Duke Energy is one of the largest electric power holding companies in the United States. It generates electricity from a variety of sources, including coal, natural gas, nuclear power, and renewable energy sources like solar and wind. Coal is a major source of air pollution and greenhouse gas emissions, so Duke Energy's transition to clean energy is an important step in reducing the company's environmental impact.

The transition to clean energy is a complex and challenging process. Duke Energy must balance the need to reduce emissions with the need to provide reliable and affordable electricity to its customers. The company is investing in a variety of clean energy technologies, including solar, wind, and nuclear power. Duke Energy is also working to improve the efficiency of its existing coal-fired power plants and to develop new technologies to capture and store carbon dioxide emissions.

The transition to clean energy is essential to protecting the environment and public health. Duke Energy's commitment to close all of its coal-fired power plants by 2035 is a significant step in the right direction. The company's efforts to invest in clean energy technologies and to improve the efficiency of its existing coal-fired power plants will help to reduce air pollution, greenhouse gas emissions, and the overall environmental impact of electricity generation.
