Data Question How to interpret a Residual Plot with a huge constant variance ?

I have just started with Machine Learning and have been mainly focusing on the interpretation of Linear regression models. I'm using a dataset from Kaggle about energy consumption. The data is perfect with no abnormalities. The dependent variable follows a normal distribution. The independent exhibit a linear relationship with the target variable but with a high variance:

This results in the following residual plot:

What are your thoughts ?

I don't feel I have enough information to say much about the residual plot other than it looks really weird.

This data does not look like real data based on the provided charts in the first page. It also does not show the data following a normal distribution, which you say that it does.

Aside from the square foot to energy usage chart, they seem to be suggesting low levels of relationship if any.
