Option 1 is incorrect because focusing solely on one reliable database limits the scope and diversity of information available to Jaco. While a single database might provide a wealth of information on its own, it may not cover all relevant aspects of renewable energy adoption due to varying disciplinary approaches, methodologies, and insights that different databases might offer.
By restricting his research to just one source, Jaco risks missing valuable perspectives, data, and trends that could come from exploring multiple databases across academic, industry, and government sectors. These diverse sources can provide a more comprehensive understanding of the topic, ensuring Jaco can access the latest research articles, industry reports, policy documents, and best practices.
In summary, using diverse information systems with adjusted search terms and filters ensures that Jaco assembles a well-rounded and detailed view of renewable energy adoption in South African households, which is crucial for a robust and effective analysis.
