Question 5: What is the difference between biomass and fossil fuels?
The main differences between biomass and fossil fuels are:
Comprehensive structured answer:
- Source: Biomass is derived from organic matter, such as plants, agricultural crops, or wood pellets. Fossil fuels, on the other hand, are formed from ancient fossils and decayed organic material over millions of years.
- Renewability: Biomass is considered a renewable energy source as it can be replenished through sustainable practices. Fossil fuels are non-renewable resources, as they are finite and take millions of years to form.
- Carbon emissions: Burning biomass releases CO2 into the atmosphere, but the carbon emitted is part of the natural carbon cycle and is absorbed by new biomass growth. Fossil fuels release stored carbon that has been out of the natural carbon cycle for millions of years, contributing to increased atmospheric CO2 concentrations and climate change.
- Energy intensity: Fossil fuels have a higher energy density compared to biomass, meaning they contain more energy per unit of volume or mass.
- Environmental impact: Biomass, when produced sustainably, generally has lower environmental impacts compared to fossil fuels. Fossil fuels extraction and combustion contribute to air and water pollution, habitat destruction, and negative climate impacts.
Question 6: Can biomass renewable energy be used for transportation?
