Operating expenses Fuel prices per kWh may be calculated and show that oil-fired power is the most expensive, with coal coming in second and gas being the least expensive. Nuclear fuel is significantly less expensive per kWh. However, nuclear power plants also have major operating costs that include cleanup after accidents.
But when all the costs are included, coal comes out on top. The main advantage of solar and wind power is their lack of cost once you account for the grid connection fee and any government subsidies. Both technologies are still very expensive compared to coal and fossil fuels overall though.
The main advantage of nuclear power is its ability to produce electricity even during a disaster. All other forms of power production are limited by how quickly they can be shut down and replaced which means they would only be able to supply enough electricity to meet basic needs during normal times and not during an emergency. Also, since nuclear power plants are built near large populations centers it gives them some protection in case of attack.
Nuclear power plants are also much safer than other methods of producing electricity. There have been no deaths due to nuclear power plant leaks or explosions. On the other hand, there have been over 100 deaths due to natural gas leaks and explosions and over 30 deaths due to coal mine explosions each year in the United States alone.
Affordability. Energy generated by coal-fired power plants is less expensive and more accessible than energy provided by other energy sources. Because coal is abundant, producing power with it is unquestionably inexpensive. Furthermore, extracting and mining coal resources is not costly. As a result, its price remains cheap in comparison to other fuels and energy sources. 3.4 billion tons of coal were mined in 2014. That's about 10 million truckloads.
In addition to being an abundant source of energy, coal also provides many other advantages. It is clean and reliable and can be used to provide heat as well as electricity which makes it useful for various applications including heating, cooling, and power generation. Also, it does not produce carbon dioxide when burned; instead, it gives off carbon monoxide and other pollutants that contribute to global warming. However, some modern technologies can reduce these emissions significantly.
The low cost of coal-generated power is due to its abundance and the fact that it can be produced at any time of day or night without stopping production. This allows it to serve as a stable source of energy for consumers who need constant power but cannot afford to pay for peak hours on electricity prices.
Furthermore, coal is easy to transport and store. It does not require special facilities to prepare for use nor do they degrade over time. Coal storage tanks can be up to 100 years old without any major maintenance needed.
The most affordable source of energy. It is significantly less expensive than nuclear power, natural gas, and oil. Unlike other kinds of energy (nuclear, natural gas, oil, and hydropower), coal creates a large number of employment in the extraction of coal from the soil, transportation of coal to the utility, combustion of coal, and efficient disposal of coal ash. The main environmental concern with coal is greenhouse gases produced when it is burned. However, coal can be cleaned up using modern technology.
Yes, if you adjust the price for pollution, then coal is one of the best sources of energy. Coal produces half as much carbon dioxide as oil but three times more than natural gas. If we want to stop global warming, then coal must remain part of the solution not the problem. Oil and natural gas will still be needed in large quantities for vehicles and heating, so they should be used together with clean energy sources such as solar or wind.
Electricity generated from coal remains an important source of energy for our homes and businesses. The main advantage of coal over other fuels is its wide availability and low cost. We need coal to generate electricity because it's the only resource that can produce high amounts of energy with little effort. Other resources such as sunlight, wind, and water are free resources that cannot be controlled by man. They may be plentiful at some times and places but not at others. Coal, on the other hand, can be found almost everywhere on Earth.
