How much cost is needed to erect a 1MW Thermal power plant?
Answer
The capital cost to erect a 1 MW thermal power plant typically ranges from approximately 5 to 7 crore INR. This estimate varies significantly based on factors such as the technology used (e.g., supercritical vs. subcritical), the location, land acquisition costs, and the specific environmental compliance equipment required.
Classify the various energy resources.
Answer
Energy resources are primarily classified based on their availability and renewability into two main categories:
- Renewable Energy Resources: These are natural resources that replenish themselves over a short period of time and are virtually inexhaustible. Examples include solar energy, wind energy, biomass, geothermal energy, and hydroelectric power.
- Non-Renewable Energy Resources: These are finite resources that exist in fixed amounts and take millions of years to form. Once consumed, they cannot be replaced within a human timeframe. Examples include fossil fuels such as coal, petroleum, natural gas, and nuclear fuels like uranium.
Additionally, energy resources can be classified as Primary (natural sources like coal or sunlight) and Secondary (converted forms like electricity or hydrogen).
