From fences to megawatts: how Bitcoin miners are buying energy in a new way

The energy world is experiencing a quiet revolution. Bitcoin miners are no longer hunting for traditional energy sources — they are rewriting the rules of the game, leaving behind the very “fence” that for centuries concealed cheap electricity. Today, they buy energy that was previously simply wasted, turning waste into profit.

Industrial centers used to be tied to ports and labor. Bitcoin changed everything. For a data center with ASIC miners, only one thing is needed: a good warehouse, small teams, fiber optics, and — most importantly — cheap energy that no factory wants to buy. This radically shifts the geography.

From Chinese hydropower to American solar energy

The global hash rate is migrating faster than political promises. A few years ago, Chinese hydropower plants dominated mining during the rainy season. Now, over 41% of all Bitcoin blocks are mined by American pools. Why? The US has learned to buy what was previously just wasted.

CAISO (California Independent System Operator) in 2023 dumped 3.4 TWh of solar and wind energy — 30% more than the year before. By early 2024, already 2.4 TWh have been lost. When electricity prices turn negative, generators have to pay the grid to accept their energy. That’s where Bitcoin miners come in.

Riot Platforms, one of the largest miners in the US, received $71 million in electricity credits in Texas last year — an amount exceeding the value of the BTC mined. By early 2026, companies have found a new way to buy cheap energy: by 2025, Riot already received $46 million. The numbers speak for themselves.

Modular centers, burned gas, and wind farms: a new economy

Soluna installs modular data centers directly on wind farms. Crusoe doesn’t waste burned oil gas in Texas deserts — they buy it and turn it into hashes. MARA tests heat reuse systems in Finland, powering district heating with residual heat from miners.

This approach fundamentally changes the relationship between energy producers and industry. Previously, high loads were just pass-throughs; today, they are assets. Lancium, for example, develops a network of “controllable loads” that can instantly shut down during heatwaves, helping stabilize the grid.

AI is closely watching this process, but with a serious limitation: AI data centers are tied to cities due to latency. Bitcoin, on the other hand, is “indifferent to downtime” — it can find cheap energy on any continent.

Global expansion: from Bhutan to El Salvador’s volcanoes

Bhutan never considered hydropower its biggest asset until Bitdeer came to buy 100 MW of capacity. Now, the country funds development through clean Bitcoin coins. Kentucky abolished the electricity sales tax for miners. Norway no longer sees flaring gas as a problem — it sells it to miners.

The most ambitious project: El Salvador is building Bitcoin Cities powered by volcanic energy. Lithium mines are emerging in Chile, closing the “clean energy” cycle. Traditional industrial fences are falling everywhere — new allies are taking their place.

The future frontier

By 2035, experts expect a radical restructuring of energy clusters. Cities may mostly turn into substations and overnight hubs, while main computing power disperses around the world where cheap energy and fiber optics flicker in the dark.

Bitcoin isn’t hunting for energy as such — it’s hunting for waste, systemic flaws, and the money energy companies are willing to spend to “buy out” someone else. And it will probably buy it. From the fence of traditional industry to megawatts of smart energy — this is not just an evolution of mining, but a rewriting of the world’s economic geography.
