Learn Swedish: Omställningen kräver förnybar energi, inte minst el. - The transition requires renewable energy, not least electricity.

Both highlight a specific example, but inte minst (not least) carries a distinct rhetorical weight. By saying the transition requires renewable energy, "not least" electricity, it emphasizes that el is perhaps the most critical factor, often implying that its importance shouldn't be underestimated. You could use särskilt (especially) or framför allt (above all), but inte minst is extremely common in formal or journalistic Swedish for driving home a strong point.

Is omställningen a general word, or does it have a specific meaning in this context?

Literally, en omställning just means "a transition", "a conversion", or "an adjustment". However, in contemporary Swedish news and politics—especially when paired with terms like förnybar energi—it is the standard, everyday shorthand for klimatomställningen (the climate transition) or den gröna omställningen (the green transition).

Why use kräver in this sentence instead of behöver?

While behöver simply means "needs", kräver means "requires" or "demands" (from the verb att kräva). Using kräver fits the formal, objective tone of the sentence and implies a strict condition: the transition absolutely cannot succeed without it.

I know the Swedish word for electricity is elektricitet. Why use here?
