Here are the solutions to Section B: Analytical Questions: 1. Solar PV systems convert sunlight directly into electricity using photovoltaic cells. They produce no emissions during operation and have low maintenance requirements. However, their power output is intermittent, depending on sunlight availability, and they require energy storage for continuous supply. Thermal power generation systems (e.g., coal, natural gas, nuclear) burn fuel to heat water, create high-pressure steam, and drive a turbine to generate electricity. These systems offer dispatchable power (can be controlled to meet demand) but typically have higher operational emissions (except nuclear) and require continuous fuel supply and waste management. 2. Natural gas offers several advantages over coal as a fuel for power generation. It burns cleaner, producing significantly less carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter, which reduces air pollution and greenhouse gas emissions. Modern natural gas power plants are also generally more efficient than coal plants and can be ramped up or down more quickly, providing greater flexibility for grid management and balancing variable renewable energy sources. 3. The limitations of renewable energy in industrial applications include intermittency, as sources like solar and wind depend on weather conditions, requiring costly energy storage or backup systems. They often have a substantial land footprint for large-scale installations. The high initial capital costs for setting up renewable infrastructure can be a barrier for industries. Furthermore, the grid integration of variable renewable sources can be complex, necessitating significant upgrades to existing electrical infrastructure to maintain stability and reliability.
