Correct. Don't have data on exactly how much more energy it would take to make an ad targetted, but if we consider the process:

-you need to track what the user does, which takes energy,

- store this information in a server that takes energy to run, and then

-actually 'choose' the correct type of ad, which takes energy again,

I'd say it's very fair to assume that it is More. Also, while solar and wind don't output pollution during operation, a signifcant amount of pollution happens during their manufacturing, so while it is 'cleaner', we still can't say its fully 'clean'. And of course you have to incorporate the lifespan of these things, and how efficient they are at their job. So, regardless of energy source, it's still not great that it uses more.

Also I've said this before but advertising is an industry that should be considered as pointless and harmful as fossil fuels.
