"and other negative effects.\n" | |
"3. Cost: Renewable energy sources can be more expensive to initially set up, but they typically " | |
"have lower operational costs than non-renewable sources.\n" | |
"4. Reliability: Renewable energy sources are often more reliable and can be used in more remote " | |
"locations than non-renewable sources.\n" | |
"5. Flexibility: Renewable energy sources are often more flexible and can be adapted to different " | |
"situations and needs, while non-renewable sources are more rigid and inflexible.\n" | |
