Answer:
The university study.
Explanation:
In this example, a blog about solar energy would probably be informative, but since it is not an academic source, it could be written by anyone and the information would have to be taken with a grain of salt.

A university, on the other hand, would have access to the latest scientific, proofread papers on solar energy research.
