Answer 1

$\huge\mathfrak\orange{Answer.!!!!!}$

ADVANTAGES OF COAL:

•It is available in an abundant supply.

•It has a high load factor.

•Coal offers a rather low capital investment.

•Carbon capture and storage technologies can reduce potential emissions.

•It can be converted into different formats.

•Coal can be used with renewables to reduce emissions.

DISADVANTAGES OF COAL:

•It is not a renewable resource.

•Coal contains a high level of carbon dioxide per British Thermal Unit.

•Coal power can create high levels of radiation.

•Coal emissions are linked to health concerns.

•Even clean coal still has high levels of methane.

Answer 2

Answer:

ADVANTAGES OF COAL:

1. It has a high load factor.

Using coal as a fuel provides a society with the potential for continuous power. Many infrastructures are specifically designed to use coal, offering a good utilization rate for this fossil fuel. It also provides a high load factor, giving us access to an efficient and predictable level of energy through combustion. That’s predictability isn’t something that other fuel resources can currently provide with current technologies.

2.Coal offers a rather low capital investment.

Many of our fuel and power generation technologies are already designed to use coal. This limits the amount of a capital investment which is required to create a new societal resource, especially when compared to nuclear or renewable energy resources.

3.Carbon capture and storage technologies can reduce potential emissions.

Safe capture and storage of carbon dioxide, referred to as CCS, is a technology that would capture and store the carbon dioxide that is produced by combusting this fossil fuel. Scrubbers and filters can also capture the CO2 before it is able to get into the atmosphere. This limits the amount of potential global warming that would be triggered by an increase in coal use.

DISADVANTAGES OF COAL:

1. It is not a renewable resource.

At some point, if we are continuously using coal for our power and energy needs, it will eventually become depleted. As a fossil fuel, there is a finite supply. We may have centuries of stockpiles available in some regions, but at some point, there must be a backup plan in place that can be implemented.

2.Coal power can create high levels of radiation.

A byproduct of burning coal for power, called “coal ash,” produces radiation. This ash then settles around the surrounding areas of the coal plant. According to Scientific American, a coal power plant can produce up to 100 times more radiation than a nuclear power plant. Coal combustion can also produce mercury, nitrous oxide, heavy metals, and other potential environmental dangers.

3.Coal emissions are linked to health concerns.

People who are exposed to coal and its emissions have an increased risk of experiencing asthma and other air passageway inflammation conditions. Breathing in coal dust or ash is also known to be a cause for lung cancer development over time. A coal mining disease called “Black Lung” can impact total lung capacity, is incurable, and is often fatal. People with Black Lung literally die of suffocation.
