szénenergiaforrásokra

Szénenergiaforrásokra refers to energy sources derived from coal. Coal, a fossil fuel, is formed from the remains of plants that died millions of years ago and were subjected to heat and pressure underground. It is primarily composed of carbon, along with varying amounts of hydrogen, sulfur, oxygen, and nitrogen.

The extraction of coal is done through mining, which can be surface mining or underground mining. Once extracted, coal is typically processed to remove impurities before being used as an energy source. The most common method of utilizing coal for energy production is through combustion in power plants. This process heats water to produce steam, which then drives turbines connected to generators to produce electricity.

Historically, coal has been a dominant energy source globally, powering industrial revolutions and providing electricity for homes and businesses. Its abundance and relatively low cost have contributed to its widespread use. However, the combustion of coal releases significant amounts of greenhouse gases, particularly carbon dioxide, which is a major contributor to climate change. It also releases other pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which can have adverse effects on air quality and human health.

Due to environmental concerns, there is a global trend towards reducing reliance on coal and transitioning to cleaner energy alternatives, such as renewable energy sources and natural gas. Despite this, coal remains a significant energy source in many parts of the world, especially in developing economies. Research and development efforts are ongoing to explore cleaner coal technologies, such as carbon capture and storage, to mitigate the environmental impact of its use.
