The web search results discuss the potential impact of the Iran war on the green transition and energy diversification, mentioning China's role, but none of the provided evidence explicitly states that the US war on Iran *may have inadvertently triggered a global transition that will favour Beijing's green leadership* as a unified, analyst prediction. The evidence points to acceleration away from fossil fuels generally, but the specific causal link favoring Beijing is not corroborated by multiple independent sources.

The web search results confirm that Cuba faces an energy shortage amid a US blockade and that China has relations with Cuba. One web search result mentions rendering the oil blockade ineffective through alternative energy. However, no independent news sources corroborate the specific claim that solar panels *from China* have provided a model of independence for Cuba in response to the blockade, nor is this presented as a widely reported consensus.

The claim attributes specific data (6% to over 20% increase in solar share) to 'Microgrid Media, a California-based publication.' The evidence provided for this claim only contains general web search results about solar power in other locations (Morocco, Germany) and general Wikipedia articles, but none of the evidence directly quotes or corroborates the specific statistics or the source 'Microgrid Media.'

The claim references a specific report published on February 23rd stating that Cuba neutralized the oil blockade using alternative energy. One web search result matches the content ('By rendering the oil blockade ineffective through alternative energy, Cuba neutralizes what had been America’s primary economic weapon'), but this appears to be from a single, partisan source ('Friends of Socialist China'). No other independent sources corroborate this specific conclusion or the report's existence.

The claim provides specific figures (92 parks, 2,000 MW by 2028) that are directly quoted in the web search results. However, these figures are only present in the search results related to Cuba's solar plans and are not corroborated by any other independent source or authoritative reference provided in the evidence set.

The web search results discuss the general acceleration toward renewables due to energy shocks (Iran war context), but none of the provided evidence explicitly links this acceleration to the *reduction of oil and gas supplies from the Middle East* as the primary driver, nor is this stated as a consensus view across multiple independent sources.

The web search results strongly suggest China's leadership in renewable energy development and investment. However, the claim that 'China leads in all of them' is an overgeneralization. While the evidence highlights China's massive investment and growth, it does not provide a comprehensive comparison across *all* sectors (e.g., EVs, infrastructure) to definitively prove it leads in every single category globally, making it a single-source assertion based on the provided search snippets.
