On link aggregator sites like this you would normally put the article URL as the main link so people can click on your title and be taken to the article. Having a picture as the main link like you've done would normally be done if the picture was what you wanted to discuss. It's not a real problem how it is currently but it is different to how someone would normally post article links.

Luckily you can edit posts on Lemmy, so what they're suggesting is to go to edit the post and put the article URL in the field labelled URL so your post follows expected behaviour, and if you really wanted a link to the picture you could put that in the description like you currently have the article link.

I am done with your trolling arblip3!🤣

It needs to be carefully calculated what is better. There is less carbon per joule in oil. But power stations are more efficient than ICUs. But there are transmission and storage losses for electricity. But some electricity comes from wind. But transporting fuel also isn't emission-free. The list goes on. If we only have nuclear, it would solve this dilemma.
