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.

A power purchase agreement, or PPA, is one of the most important contracts in modern energy — and one of the least understood. It is how solar farms get financed, how companies lock in electricity prices, and how power gets sold before it is even generated. Here is what a PPA is, how it works, and why it matters more than most people realize.

Solar is cheap. Wind is booming. Batteries are getting better. So why does the clean energy transition still feel stuck in traffic? The answer is grid congestion—a quiet, technical bottleneck that’s turning renewable momentum into delay, waste, and frustration. Here’s the simple version, without the industry fog.

AI looks invisible, but it behaves like heavy industry in disguise. Every prompt wakes up chips, cooling systems, power electronics, and entire data centers that already consume electricity on the scale of countries. This is AI’s energy problem in plain English: what it is, why it exists, how big it is now, and why it matters.

Dive into Energy

Energy is a big topic, so I’ve broken it down into the essentials. Kick things off wherever you feel the spark:

The foundation: volts, watts, and everything you need to make sense of energy.

From fire and steam to nuclear and beyond — how energy shaped civilizations.

Wind, sun, and water: the clean power sources of tomorrow.

Balancing growth, resources, and innovation to secure our future.

Who buys, who sells, and how the flow of energy shapes economies.

Engines, fuels, and the journey toward clean mobility.

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.
