Microsoft is debating internally whether to delay or weaken its 2030 clean energy plan. The reason is not hidden: AI data centres need energy now, and the sun and wind can't deliver power „on demand".

In 2020 the company pledged that by 2030 every hour of its consumption would be matched by clean energy on the same grid. An ambitious target - hourly matching, not annual. The difference is fundamental: annual targets are an accounting trick where a company buys green credits somewhere far away and claims it is „carbon neutral". Hourly matching means real green power at the right moment, on the right grid.

Meanwhile, Microsoft is building gas plants. Together with Chevron, it is building a 5-gigawatt capacity on natural gas in west Texas. Five gigawatts - roughly the output of three nuclear reactors. That is not „transition" - that is the construction of new fossil energy infrastructure with a clear intent to run for a decade or more.

Why does that matter to European readers? Because the data centres the EU attracts with billions in investment run on the same maths. AI demands energy. Clean energy is variable. Gas is stable and cheap. Even a company that sells itself as „the green leader" - Microsoft was the first tech giant to make climate pledges - is now buying its own excuse.

Microsoft's internal argument says abandoning the hourly target could be a PR catastrophe. Hourly matching is a competitive advantage in negotiations with municipalities that don't want a giant power-guzzler in the neighbourhood. Without it, what does Microsoft sell - „we are like everyone else"?

Conclusion without illusions: the 2020 climate pledges were made in an era when nobody predicted that one hour of training an AI model would consume electricity like a small town. Now that the assumptions are false, the corporations are massaging the numbers. The question isn't whether Microsoft will miss the target - but how gracefully it will be done.
