JNTU B.Tech IV RENEWABLE ENERGY SOURCES Previous Question Paper (September - 2022 - R16)
Answer any five questions. All questions carry equal marks.
Main
Enumerate the differences between conventional and non-conventional energy sources and give examples for each.
Answer
| Feature | Conventional Energy | Non-Conventional Energy |
|---|---|---|
| Availability | Finite and exhaustible | Infinite and inexhaustible |
| Environmental Impact | High pollution (CO2, SOx, NOx) | Environmentally friendly (low/zero emissions) |
| Cost | Low initial, high running/fuel cost | High initial, low running cost |
| Technology | Mature and established | Developing and evolving |
Examples of conventional energy include coal, petroleum, natural gas, and nuclear power. Examples of non-conventional energy include solar, wind, biomass, geothermal, and tidal energy.
Analyze the importance of renewable energy in-terms of CO2 reduction.
Answer
Renewable energy sources are critical for CO2 reduction because they generate electricity without the combustion of fossil fuels. Conventional thermal power plants rely on burning coal or gas, which releases significant quantities of carbon dioxide, the primary greenhouse gas driving climate change.
By transitioning to renewable sources like solar and wind, the power sector can decouple energy production from carbon emissions. This shift reduces the carbon footprint of the energy grid, mitigates global warming, and helps nations meet international climate targets such as the Paris Agreement. Furthermore, renewable energy minimizes the extraction and transportation of fossil fuels, which indirectly reduces the carbon emissions associated with those industrial supply chains.
