Across
- 1. This energy source comes from organic materials like wood, crops, and animal waste. It can be burned to produce heat or converted into biofuels for transportation.
- 6. This energy source utilizes heat from the Earth's interior. Geothermal power plants harness this heat to generate electricity or provide direct heating and cooling.
- 9. This energy source is a clean and versatile fuel. It can be produced from various sources and used in fuel cells to generate electricity or power vehicles.
- 10. This energy source harnesses the power of ocean tides. Tidal turbines generate electricity by capturing the energy of rising and falling tides.
- 11. This energy source is a fossil fuel extracted from the ground. It is commonly used as a fuel for transportation and to generate electricity in power plants.
- 12. This energy source utilizes the force of moving water, such as rivers or ocean tides. It can be harnessed through hydroelectric power plants to generate electricity.
- 13. This energy source is a fossil fuel found deep underground. It is often used for heating, cooking, and electricity generation. It produces less pollution than coal.
Down
- 1. This energy source is derived from living organisms, such as plants or algae. It can be processed into liquid fuels, such as ethanol, for transportation purposes.
- 2. This energy source is a type of liquefied petroleum gas. It is often used for heating, cooking, and powering certain appliances, especially in rural areas.
- 3. This energy source harnesses the power of moving air. Wind turbines convert the wind's kinetic energy into electricity, providing a clean and renewable source of power.
- 4. This energy source comes from splitting atoms in a process called nuclear fission. It generates a large amount of heat, which is then converted into electricity.
- 5. This energy source is a type of alcohol made from plants like corn or sugarcane. It is often mixed with gasoline to reduce emissions and increase fuel efficiency.
- 7. This energy source is a potent greenhouse gas but can also be captured and used as a fuel. It is commonly found in landfills and wastewater treatment plants.
- 8. This energy source is a black rock found underground. It is burned to produce heat and is a significant source of electricity generation in many countries.
- 14. This energy source provides us with heat and light. It is the ultimate source of energy for all living things and can be converted into electricity using solar panels.
