- Fossil fuel is a general term given to combustible products of buried organic matter that decayed under extreme temperature and pressure
- Examples of fossil fuels include crude oil, petroleum, coal, and natural gas
- Biogas is a gas produced from anaerobic decomposition of organic matter
- Advantages of Biogas:
- Biogas is eco-friendly and renewable
- Gas generated through biodigestion is non-polluting
- Biogas generation reduces soil and water pollution
- Biogas generation produces organic fertilizer
- It's a simple and low-cost technology that encourages a circular economy
- Healthy cooking alternative for developing areas
- Disadvantages of Biogas:
- Few technological advancements
- Contains impurities
- Effect of temperature on biogas production
- Geothermal energy refers to the heat produced inside the Earth and is harnessed from molten rocks near volcanic regions
- Hydrothermal energy refers to the heat obtained from hot water from hydrothermal vents or seawater in contact with hot rock beds
- Batteries are electrochemical cells that store and convert chemical energy into electrical energy
- Solar cells can collect light energy from the sun and convert it into electricity
- Biomass is organic matter from living organisms that can be converted to energy
- Renewable energy sources are naturally replenished, while nonrenewable energy sources will get depleted over time
