I would take this further and find out what is the most energy intensive computing task across these DCs and attack those first. This is a huge unknown for me as I have no statistics on what activities result in the most energy usage in these DCs but if I have to guess, it is probably GPU/Database. I would also tax personal data. Current regulatory framework strangely assumes that personal data has no value yet entire companies are built around monetizing and claiming it as theirs. Those companies are also the biggest consumers of these DCs. Even by taxing personal data that is being used by companies, you could realize significant energy savings as they have to discern between what they need and what they dont. Asking for someones driver license to verify their account? Tax them yearly. Suddenly companies that dont really need it find themselves searching for more energy efficient solutions since their tax dollars depend on this activity. Unfortunately, we may not see this happen for quite some time.
