The main differences between conventional and unconventional sources of energy are:
1. Renewability: Conventional sources like coal, oil, and natural gas are finite and non-renewable, while unconventional sources like solar, wind, and hydropower are renewable and can be replenished naturally.
2. Environmental Impact: Conventional sources contribute to pollution and environmental degradation, whereas unconventional sources are eco-friendly and produce little to no harmful emissions.
3. Efficiency and Cost: Conventional energy sources are often more efficient but have higher operational costs and environmental costs. In contrast, unconventional sources have lower environmental costs, but initial setup costs can be higher, and efficiency may vary depending on technology.
4. Availability: Conventional sources are widely available, though they are becoming scarcer, whereas unconventional sources are less widely available but rapidly increasing due to technological advancements.
