Start with the question
An energy market can mean generation, equipment, services, fuels, infrastructure or a specific customer group. A report becomes more useful when it states the product, geography, time period and decision the research will support.
Build an evidence map
Useful sources may include official statistics, regulators, company filings, project announcements, trade associations and published research. Each source should be dated and linked to the claim it supports.
Separate fact from interpretation
A good report distinguishes reported data, an estimate based on stated assumptions and an analyst interpretation. That distinction gives decision makers a clearer view of confidence and risk.
