Ohjefossiilit

Ohjefossiilit, also known as "fossil fuels" in English, are natural resources that have formed over millions of years from the remains of ancient plants and animals. They are primarily composed of carbon, hydrogen, and oxygen, and are used as a source of energy for various purposes, including electricity generation, transportation, and heating. The most common types of ohjefossiilit are coal, oil, and natural gas. Coal is formed from the remains of ancient plants, oil from marine organisms, and natural gas from both marine and terrestrial sources. These resources are non-renewable, meaning they take millions of years to form and are being depleted at a rate much faster than they can be replenished. The extraction and use of ohjefossiilit have significant environmental impacts, including air and water pollution, greenhouse gas emissions, and habitat destruction. Due to these concerns, there is a growing global movement towards transitioning to renewable energy sources.
