What is a disadvantage of renewable energy?

• A. Sustainable so will not run out
• B. Reduces operational cost
• C. Little or no waste
• D. Expensive (capital cost of new tech)

Answer: (D)

The main idea is that, while renewable energy brings long-term benefits, the upfront expense is a significant drawback. Renewable technologies like solar panels and wind turbines have low running costs and are sustainable, and they also produce little waste. However, the initial capital required to manufacture, install, and connect these systems (and to add storage or grid upgrades) can be quite high. This upfront cost can slow adoption, even though ongoing operating costs are lower and there are no fuel costs. So the most fitting disadvantage described is the expensive initial capital outlay.
