szénhasználat

Szénhasználat refers to the extraction and utilization of coal, a combustible black or brownish-black sedimentary rock, composed primarily of carbon. It is formed from ancient plant matter that has been subjected to heat and pressure over millions of years. Coal is a fossil fuel and a major source of energy globally.

The primary uses of coal are for electricity generation and industrial processes, particularly in steel production. In power plants, coal is burned to heat water, producing steam that drives turbines to generate electricity. This process is a significant contributor to global energy supply but also a major source of greenhouse gas emissions, contributing to climate change.

Coal mining is the process of extracting coal from the ground. This can be done through surface mining, where the land is excavated, or underground mining, which involves digging shafts and tunnels. Both methods have environmental impacts, including habitat destruction, water pollution, and land degradation.

Historically, coal played a pivotal role in the Industrial Revolution, powering factories and transportation. While its dominance has been challenged by other energy sources like natural gas and renewables, coal remains a significant component of the global energy mix, especially in developing economies. Concerns about air pollution and climate change are driving efforts to reduce coal consumption and transition to cleaner energy alternatives.
