What are advantages and disadvantages of renewable resources?
Disadvantages of renewable energy resources
| Energy Resource | Advantages | Disadvantages |
|---|---|---|
| Hydroelectric power stations | Clean and cheap to run | Expensive to set up and output could be affected by drought |
| Solar cells | Clean and cheap to run | Not always sunny and output does not always outweigh initial cost to set up |
Why renewable energy is bad?
Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants. The production of some photovoltaic (PV) cells, for instance, generates toxic substances that may contaminate water resources.
Is renewable energy good or bad?
They don’t damage our planet. These clean energy sources are non-pollutant, produce minimal or no waste products, and don’t contribute to global warming – great news for the environment! They’re low-maintenance energy sources. Renewable energy facilities tend to require less maintenance than traditional generators.
