Sample interview questions: How would you assess the potential of renewable energy sources, such as wave or tidal energy, in mitigating climate change?
Sample answer:
-
Wave energy: Wave energy has the potential to contribute significantly to mitigating climate change by providing a clean, reliable, and renewable source of electricity. The energy in waves can be harnessed using various technologies such as oscillating water columns, wave overtopping devices, and submerged pressure-differential systems. The Intergovernmental Panel on Climate Change (IPCC) estimates that wave energy could potentially provide up to 10% of global electricity demand.
-
Tidal energy: Tidal energy is another promising renewable energy source that can help mitigate climate change. Tidal energy is generated by the movement of water caused by the tides. Tidal turbines, which are similar to wind turbines, can be installed in tidal currents to convert the kinetic energy of the moving water into electricity. The IPCC estimates that tidal energy could potentially provide up to 5% of global electricity demand.

Both wave and tidal energy have the potential to reduce greenhouse gas emissions by displacing fossil fuels and providing clean, renewable electricity. Additionally, these technologies can contribute to energy security by diversifying the energy mix and reducing reliance on imported fuels.
