Question Detail
Out of the following which one is not a unconventional source of energy ?
Options
Option A: Tidal power
Option B: Geothermal energy
Option C: Nuclear energy
Option D: Wind power
Correct Answer
Nuclear energy
Solution & Explanation
{"type":"technical","methodBadge":"Concept & Principle","explanation":"Nuclear energy is classified as a conventional source of energy because it has been used for industrial-scale power generation for decades, similar to coal, oil, and gas. Unconventional sources (also known as renewable or non-conventional) are those that are still in developmental phases or have only recently been harnessed at scale, such as tidal, wind, and geothermal energy.","workingPrinciple":"Nuclear power plants utilize controlled fission reactions. A heavy nucleus like $^{235}U$ is bombarded by a neutron, causing it to split into lighter nuclei, releasing immense heat energy and additional neutrons. This heat is used to produce steam, which drives a turbine connected to an electrical generator.","diagramSvg":"Reactor CoreTurbineGen","keyFormulas":["$E = \\Delta m c^2$ тАФ Einstein's mass-energy equivalence describing the energy released during nuclear fission","$Q = mc\\Delta T$ тАФ Heat energy transfer principle applied in steam generation"],"keyPoints":["Conventional sources are characterized by established infrastructure and widespread usage.","Nuclear energy is distinct from renewable sources; it is a non-renewable but low-carbon conventional energy source.","The International Energy Agency classifies nuclear power as a mature commercial technology."],"advantages":["High energy density compared to fossil fuels.","Provides stable base-load power unlike intermittent renewables."],"disadvantages":["Generates radioactive waste requiring long-term storage.","Risk of nuclear accidents and high initial capital costs."],"applications":["Base-load grid electricity supply.","Nuclear-powered marine propulsion (submarines/icebreakers)."],"comparisonTable":[],"additionalInfo":["Nuclear energy is often grouped with 'Commercial' energy sources in economic textbooks.","Tidal, Geothermal, and Wind are collectively termed 'Non-conventional' because their commercial adoption started significantly later and they rely on natural phenomena that are not depletion-based."],"answer":"C is correct тАФ Nuclear energy is considered a conventional source of energy due to its well-established, long-standing industrial use.","correctedOptions":["Tidal power","Geothermal energy","Nuclear energy","Wind power"],"coreConcepts":["Energy Classification","Nuclear Fission","Power Generation Infrastructure"],"crossTopicTip":"In competitive exams, always differentiate between 'Non-conventional' (Renewable/Recent) and 'Conventional' (Non-renewable/Established) based on the historical deployment of the technology."}
