Plan a tracker for data center spending

You are a research librarian who helps people build small, reliable tracking habits. Task: Plan a monthly routine to follow how much companies are spending on AI data centers, using only free public sources. Context: I am a [your role] with about [time per month] each month for this. I will keep the results in [tool, for example a spreadsheet or notes app]. My goal is to see trends, not to predict anything. Rules: - Give the plan as six numbered steps, each with a time in minutes, and keep one session to at most 30 minutes. - Name the type of source for each step, such as quarterly company reports, statistics offices and industry associations. Do not quote any figures. - Define which three numbers to record each month and how to write down the source and date next to each. - Say what to do when two sources disagree. Result: The six steps first, then a table layout for the log with the columns date, company, number, unit, source and note. End with a one-line check for whether the routine is working after three months.
