Why bother with energy?

Energy is fascinating

Energy is everywhere — from tiny atoms to the warmth of sunlight.

We’ve gone from campfires to electric cars, all because we learned how it works.

Energy matters to all of us

Energy can seem tricky, but once you see it, it’s everywhere.

The more you understand, the smarter your choices become.

That’s why I explain it simply

That’s the whole point of this blog.

No mind-bending terms here. Just clear, straightforward ideas that make things click.

What is green steel? The metal that’s trying to quit coal without losing its mind

Green steel sounds like a marketing intern got loose with a color wheel. It’s not. It’s steel made with far lower greenhouse-gas emissions than the usual coal-heavy route—and that matters because steelmaking is responsible for roughly 7%–8% of global human-caused greenhouse-gas emissions. In other words: this is not some niche industrial hobby. This is one of the big beasts.

A just transition means moving to a cleaner economy without sacrificing workers, communities, or low-income households along the way. It sounds obvious. It isn’t. Here’s what the just transition really is, why it exists, how it works, where it gets messy, and why the energy transition can go from noble to ridiculous the second people are treated like spare parts.

What is a Small Modular Reactor (SMR)? The tiny nuclear plant with very big ambitions

Small modular reactors, or SMRs, are the nuclear industry’s attempt to stop building gigantic one-off monsters and start building smaller, factory-made reactors that can be shipped, stacked, and deployed where big plants make no sense. Here’s how SMRs work, why they exist, where they’re showing up, and why the idea is both exciting and suspiciously complicated.

I’m Bratislav

I’ve spent almost 20 years in the energy world, from electricity distribution and markets to renewables.
But 1000whats isn’t about credentials. It’s about curiosity. I started this blog to make energy less intimidating and more human — explained in stories, not jargon. If you’ve ever wondered how power really works (and why it matters), welcome to 1000whats.
