Answer (1)
1. What is a good fuel?A good fuel is one that burns efficiently, produces a large amount of energy per unit, is readily available, affordable, easy to transport, and produces minimal pollution. Examples include LPG, natural gas, and ethanol.2. If you could use any source of energy for heating your food, which one would you use and why?I would use electricity from solar energy because it is clean, renewable, and safe. It doesn’t produce harmful emissions and helps reduce our carbon footprint.3. Why are we looking at alternate sources of energy?We are exploring alternate sources because fossil fuels are limited, polluting, and contribute to climate change. Renewable energy sources like solar, wind, and hydro are sustainable and environmentally friendly.4. What are the disadvantages of fossil fuels?Fossil fuels cause air pollution, contribute to global warming, are non-renewable, and can lead to environmental damage through oil spills and mining. They also pose health risks to humans and animals.5. Can any source of energy be pollution-free? Why or why not?No energy source is completely pollution-free, but some are much cleaner than others. For example, solar and wind energy produce little to no pollution during use, though their production and installation may still have minor environmental impacts.
