Need 2 Datasets: One For Studying The Tradeoff Between Data Utility And Data Privacy, One To Study Investment In Clean Technology

Hello, I am writing a thesis (I am a student at CEMFI, Madrid.)

I have 2 projects to do:

Project 1: Use text data and do something fancy, I would like to study the tradeoff between data privacy and utility but I did not find any useful datasets.

Project 2:
I am writing a macroeconomic model about the optimal transitional dynamics towards more sustainable energy production. I am looking for a dataset with granular data where I could exploit some variation over the years in some interesting measures in order to calibrate my model.

I’d greatly appreciate any leads or suggestions on where to find relevant datasets for these projects. Thank you!
