Coal
Definition: A fossil fuel formed from the decomposition of organic materials that is burned to produce electricity. Usage: Primarily used for electricity generation and steel production. Environmental Impact: Contributes to air pollution, including carbon dioxide () emissions, and results in habitat destruction and waste products.
Uranium
Definition: A heavy metal used as fuel in nuclear reactors for nuclear fission to produce electricity. Usage: Powers civilian and military nuclear reactors. Environmental Impact: Produces radioactive waste which needs to be safely stored for thousands of years, and potential for catastrophic disasters like Chernobyl.
Peat
Definition: An accumulation of partially decayed vegetation matter, used as a fuel and precursor to coal. Usage: Burned in power plants for electricity production and used as a domestic fuel. Environmental Impact: Harvesting peat releases stored carbon and destroys peatland habitats, contributing to carbon emissions and biodiversity loss.
Oil
Definition: A liquid fossil fuel also known as petroleum, refined into various types of fuels. Usage: Used to produce gasoline, diesel, jet fuel, and heating oil; also a raw material for plastics and pharmaceuticals. Environmental Impact: Its extraction, transportation, and combustion lead to greenhouse gas emissions and oil spills can cause severe environmental damage.
Natural Gas
Definition: A gaseous fossil fuel consisting mainly of methane () used for heating, electricity generation, and as an industrial feedstock. Usage: Considered a cleaner alternative for power generation; also used in homes for cooking and heating. Environmental Impact: While it emits less CO2 than other fossil fuels, methane leakage during extraction and transport is a potent greenhouse gas.
