Step 1
Step 2
3.1.2 Name TWO challenges to using the Ocean Hydro Omni.
Answer
- Corrosion: The equipment must withstand harsh oceanic conditions that can lead to deterioration and failure.
- Biofouling: The accumulation of marine organisms on the system can reduce efficiency and increase maintenance costs.
Step 3
3.1.3 In your opinion, is South Africa ready to use renewable energy sources? Motivate your response by giving TWO reasons.
Answer
YES:
- South Africa's weather conditions are favorable for solar power generation, making renewable energy practical.
- Buildings utilizing renewable energy can reduce reliance on fossil fuels, which is advantageous for the environment and sustainability.
Step 4
3.1.4 Explain TWO negative cost considerations that currently have to be kept in mind before implementing renewable energy development in the ocean.
Answer
- The high costs associated with installing and maintaining equipment in marine environments can deter investment in renewable energy solutions.
- The development of marine infrastructure can be expensive, especially considering the potential for ocean action, storms, and long-term sustainability.
