A town reduced electricity consumption by 200 MWh after installing solar panels. This supports the idea that:
Correct answer: A. Solar energy reduces grid dependency
- A. Solar energy reduces grid dependency
- B. Windmills are outdated
- C. Incandescent light bulbs generate heat
- D. Using coal is environmentally harmful
Explanation
The correct answer is that 'Solar energy reduces grid dependency.' This conclusion is drawn from the fact that the town managed to reduce its electricity consumption by 200 MWh after installing solar panels, which suggests a decreased reliance on the main power grid. The other options are unrelated to the specific impact of solar panels on electricity consumption. Option B discusses windmills, which are not mentioned in the scenario. Option C talks about incandescent bulbs generating heat, which does not connect to the town's electricity reduction. Option D addresses coal's environmental impact, which, while significant, is not relevant to the question at hand.
