Yes, fossil fuels are hard because it's prices are increasing doubt if it clean or not because its popular uses and it's running out
"economical" has no comparative or superlative form. You would say "more economical" or "most economical."
They have a fair economical condition, or they have a hard economical condition. It's missing an adjective for the noun 'economical.' When "economical" is used as a preposition it is correct to say : They have an economical condition, with the meaning of profitable.
Women would cook, clean, and keep the house in order. :D
The economic problems with coal include its high extraction and production costs, which can make it less competitive compared to cheaper and cleaner energy sources like natural gas and renewables. Additionally, coal is subject to fluctuating market prices and increased regulatory costs due to environmental regulations, which can further strain its economic viability. As many countries transition to greener energy, coal industries face declining demand and potential job losses, creating economic challenges in regions dependent on coal production.
Lack of clean water
Yes, it is a weapon of economic/environmental warfare, used by the wealthy upon the powerless, who are nonetheless, addicted to the electricity which the burning of coal provides. The phrase "clean coal" is an oxymoron, as it is an economical and ecological impossibility, for coal to be burned, clean. "Clean Coal" is thus a lie, from the beginning. First, because it still creates several types of particulate air pollution, and the resulting toxic captured sludge is then a deadly groundwater pollutant. Second, because it is a major contributor of carbon dioxide (among other noxious gasses) and the wealth addicted parasites of the carbon industries, invest huge sums of money to deny the existence and validity of anthropogenic global climate system change, because they are the greatest single contributor to climate disasters getting ever worse.
Depends entirely on the cost of the available energy source and the invested cost in the power plant. Most of our domestic energy in US is produced by Coal. Regulations to make coal more environmentally clean will drive up the cost.

clean coal is not renewable
There isn't a single individual who can be credited with discovering the use of clean coal. Clean coal technologies have evolved over time through the efforts of numerous scientists, engineers, and researchers working to reduce the environmental impact of coal-fired power plants.
Clean coal technologies are still expensive to implement and may not reduce emissions as much as expected. There are also concerns about the disposal of byproducts such as ash and CO2 storage. Additionally, mining and transporting coal still have environmental impacts.
i think its an important issue, but not in the recent economical times in the U.S.
You don't. But coal is an economical fuel. One method of producing electricity on a commercial scale is with steam. Coal provides an inexpensive source of heat to heat water to steam, which is directed through turbines which in turn drive generators. You can do the same thing with falling water (without the steam) if you have a large enough waterfall, or you can use a different heat source like natural gas or atomic energy. Coal is sometimes more economical.
There are a large number of factors, including how much overburden is on top of the coal, and the thickness and width of the seam of coal. Less than 2 feet thick is generally not economical to mine.
Coal. Anthracite is a very hard very clean burning metamorphic type of coal.
It is very important to use clean coal technology. The pollutants from burning coal causes health problems as well as environmental problems. The clean coal technology cuts back on these pollutants and provides a cheap form of energy.
