The claim that energy dependence on imported fossil fuels is a central vulnerability is supported by a web search result referencing the general economic turmoil in Sri Lanka. While Dinouk Colombage is mentioned in relation to geopolitical advice, the specific statement linking energy dependence to vulnerability is found in a general news context, making it difficult to attribute solely to him based on the provided evidence. Since the evidence is limited to general reports of the vulnerability, and not multiple independent reports of *Colombage* making this specific claim, it is marked as single-source based on the available web search context.

The claim regarding Sri Lanka possessing 60 to 70 gigawatts of solar and wind energy is not supported by any evidence. The web search results provide general information about solar and wind capacity in other countries (Saudi Arabia, Australia) or general resources for Sri Lanka (wave energy), but none confirm the specific figure of 60-70 GW for Sri Lanka. Therefore, the claim cannot be corroborated or verified by the provided evidence.
