Across
- 2. Unrefined oil extracted from underground deposits, which is processed to create gasoline, diesel, and other petrochemical products used in energy, transportation, and manufacturing.
- 3. used as an alternative to gasoline and diesel in vehicles, known for being cleaner-burning and environmentally friendlier.
- 6. A radioactive element that has potential as a safer and more efficient alternative to uranium in nuclear reactors
- 7. A naturally occurring, flammable liquid found in rock formations beneath the Earth’s surface, which is refined into various fuels and chemical products.
- 8. Also known as oil sands, these are deposits of sand and clay that contain bitumen, a dense form of crude oil, requiring energy-intensive extraction processes.
- 9. The lowest-grade coal, with a high moisture content, primarily used in power plants to generate electricity, though it is less efficient than other coal types.
- 10. A type of liquefied petroleum gas (LPG), used primarily for heating, cooking, and fuel in vehicles, especially in rural and off-grid areas.
- 13. Energy sources such as coal, oil, and natural gas, formed from the ancient remains of plants and animals, often linked to environmental pollution and greenhouse gas emissions.
- 15. Oil extracted from shale rock formations using hydraulic fracturing, often referred to as "fracking," a controversial method for tapping into previously inaccessible oil reserves.
- 17. The highest grade of coal, characterized by its hardness, high carbon content, and energy density, mainly used for heating and some industrial applications.
- 19. A clean-burning fossil fuel consisting mostly of methane, extracted from underground deposits, used for heating, cooking, and electricity generation.
Down
- 1. A lower-grade coal that has a higher moisture content, typically used in power generation, but produces less energy per unit than bituminous coal.
- 3. A black or brownish-black fossil fuel, rich in carbon, used primarily for generating electricity and in industrial processes like steel manufacturing.
- 4. A higher-grade coal used widely in power plants for electricity generation and in industrial manufacturing, producing more heat than sub-bituminous coal.
- 5. A high-energy liquid fuel used in aviation, primarily derived from crude oil
- 11. A liquid fossil fuel derived from ancient marine organisms, refined into gasoline, diesel, and other products for transportation and industrial use.
- 12. A type of fuel derived from crude oil, used in diesel engines for trucks, buses, and trains, known for its higher energy content compared to gasoline.
- 14. Energy produced from nuclear fission reactions, where atoms are split to release heat, which is then used to generate electricity in nuclear power plants.
- 16. A radioactive metal used as fuel in nuclear reactors, where its isotopes undergo fission to release energy, which is harnessed to generate electricity in nuclear power plants.
- 18. A refined petroleum product commonly used as fuel for internal combustion engines in cars, trucks, and motorcycles.
