17. What is the estimated time to depletion for coal reserves?

    Approximately 150 years. Based on current consumption rates and known reserves.

18. Identify one limitation of solar power.

    Intermittency due to weather and nighttime. Cannot generate power when sun isn't shining.

19. Identify the primary use of petroleum.

    Fuel for transportation. Refined into gasoline, diesel, and jet fuel for vehicles.

20. What is the main environmental concern with fossil fuels?

    Carbon dioxide emissions leading to climate change. Burning releases greenhouse gases that trap heat.

21. State the formula for calculating energy efficiency.

    $\text{Efficiency} = \frac{\text{Useful Energy Output}}{\text{Total Energy Input}} \times 100\%$. Measures how much input energy becomes useful output.

22. What is the main environmental risk of nuclear power?

    Nuclear waste disposal. Radioactive waste remains dangerous for thousands of years.

23. What is a major advantage of wind energy?

    It produces no direct emissions during operation. Clean generation without air pollutants or greenhouse gases.

24. What is the energy transformation in a hydroelectric dam?

    Potential energy to kinetic energy to electrical energy. Water flows through turbines converting motion to electricity.

25. Identify one effect of burning fossil fuels on the environment.

    Air pollution. Releases particulates, sulfur dioxide, and nitrogen oxides.

26. What is the main disadvantage of biomass energy?

    It can compete with food production for land. Competes with agriculture for fertile land and resources.

27. Which type of coal has the highest energy content?

    Anthracite. Hardest coal type with highest carbon content and heat.

28. What is the largest source of renewable energy in the world?

    Hydropower. Established technology with widespread global implementation.

29. Which energy resource is derived from living or recently living organisms?

    Biomass. Includes wood, crop waste, and organic materials for energy.

30. Identify one environmental impact of coal mining.

    Land degradation. Strip mining destroys topsoil and natural landscapes.

31. What is the role of a turbine in wind energy production?

    Converts kinetic energy to mechanical energy. Spinning blades capture wind and turn generators.

32. Identify a major challenge in transitioning to renewable energy.

    Grid integration and storage of intermittent energy. Variable output requires backup systems and storage solutions.

33. Which energy resource can result in habitat destruction?

    Hydropower. Dams flood ecosystems and block fish migration routes.

34. Identify one use of geothermal energy.

    Heating buildings. Direct heat application for homes and industrial processes.

35. Which renewable energy source is derived from ocean tides?

    Tidal energy. Uses gravitational pull of moon and sun on oceans.

36. Which energy resource uses heat from the Earth's interior?

    Geothermal energy. Taps into natural heat stored beneath Earth's surface.

37. What is the main benefit of using hydropower?

    Renewable and capable of large-scale energy production. Provides consistent, reliable power with minimal emissions.

38. Which energy resource is considered carbon-neutral?

    Biomass, when sustainably managed. Absorbs $CO_2$ during growth, releasing it when burned.

39. What is the key advantage of distributed solar power systems?

    Reduces transmission losses. Power generated closer to consumption points minimizes loss.
