5 Myths About Mining with Renewable Energy That Many Still Believe… What’s the Truth?

When you hear “cryptocurrency mining”, what comes to mind? Probably giant halls filled with machines that make noise, heat up, and consume as much energy as a small country.

And… you’re half right. That’s how it looked a few years ago. But today, mining looks completely different—especially when combined with renewable energy sources (RES).

Time to bust the most common myths.🚀

Myth 1: “Mining Isn’t Profitable”

The most common phrase: “It’s a waste of electricity,” “It’s over,” “You’ll only lose money now.”

👉 The fact is: mining profitability depends entirely on the cost of energy.

• If you pay the standard retail tariff – mining makes no sense.

• But if you have your own solar panels, access to cheaper night tariffs, or an energy storage system – the story is completely different.

Concrete numbers:

• Selling surplus energy to the grid: 100–200 PLN/MWh

• Mining crypto with that same energy: 600–1400 PLN/MWh

• Negative market prices (e.g. –50 PLN/MWh): instead of paying to give away your electricity, you turn it into cryptocurrency worth hundreds of PLN.

It’s like the power plant says: “Pay us to take your electricity” – and instead, you turn it into digital gold.

💡 That’s why the myth “mining isn’t profitable” is totally detached from reality. It is profitable—just not for everyone and not under all conditions.

Myth 2: “Miners Are Always Bad for the Environment”

This is the media’s favorite. Headlines like “Bitcoin uses more power than Argentina” always get clicks.

👉 The truth? What matters is the source of the energy.

✔️ Miners powered by coal plants – not eco-friendly.✔️ Miners powered by solar panels and batteries – a completely different story.

Why?

• Mining can run when electricity is cheapest (e.g., at night, on off-peak tariffs).

• It can also kick in during excess renewable production, when market prices drop to zero or even negative.

Instead of wasting energy or paying to get rid of it, you can use it for crypto mining.

In practice, miners become flexible loads:🔹 they don’t block the grid,🔹 they don’t compete with households for power,🔹 they actually stabilize the system—switching on when power needs to be “absorbed.”

💡 So instead of seeing miners as “power hogs,” think of them as intelligent stores of value—helping the grid while generating profit.

Myth 3: “Miners Use Up All the Power in the House”

This myth started when someone plugged a miner into a socket, saw a higher bill, and declared: “The miner steals power from the fridge.”

👉 The reality is very different.

Modern systems don’t just run blindly. Thanks to automation, mining only starts when you have surplus power—for example, from solar panels.

How it works in practice:

• The house runs normally: fridge cools, computer works, washing machine runs—nothing changes.

• Surplus power goes either to the grid or to the miner.

In net-billing: surplus sold to the grid = 100–200 PLN/MWh.But when prices fall to zero or negative, prosumers actually pay to offload their electricity.

Instead of that—mining. The miner switches on only when you have excess energy, consuming what no one else wants. Instead of paying, you convert it into cryptocurrency worth 600–1400 PLN/MWh.

💡 A miner doesn’t “steal” electricity from your home. It ensures your electricity doesn’t go to waste—turning it into digital assets instead of selling cheap or paying extra.

Myth 4: “This Technology Is Only for Large Farms”

See a shipping container full of machines and think: “That’s not for me. That’s for corporations.”

👉 Truth? Mining with RES works at any scale.

1. Large PV farms (hundreds of kWp – MW)

   • Hybrid systems: PV + battery + full mining container.

   • Mining acts as a flexible load, switching on during negative prices or grid overload.

   • Instead of losing money selling cheap, the energy is monetized in crypto.

   
   

2. Medium installations (e.g., hotel, farm, factory with 30–100 kWp PV)

   • Daytime surpluses when guests/production use less.

   • A few machines consume the excess, boosting ROI.

   • Bonus: energy not only cuts costs but also generates extra income.

     
     

3. Home PV (5–20 kWp)

   • A single miner works as an “intelligent load.”

   • It runs only when home use is lower than solar production.

   • Instead of selling to the grid for 100–200 PLN/MWh, you get 600–1400 PLN/MWh in crypto.

     
     

💡 Mining isn’t limited to “a desert container.” It adapts to your installation—whether you’re a homeowner, hotelier, or factory owner.

Myth 5: “Crypto & Mining Are Just a Passing Trend”

“It will end soon,” “It’s a bubble,” “Nobody will care next year.”

👉 Reality? Bitcoin has been around for over 15 years.

During that time it evolved from a niche project into a full financial sector that central banks, funds, and governments now pay attention to.

What’s happened in those years?

• Multiple boom-and-bust cycles—from $1, to bubbles at $20,000, to today’s tens of thousands.

• Institutionalization: global exchanges (Binance, Coinbase), regulations (MiCA in the EU, SEC licenses in the US), ETFs for Bitcoin and Ethereum.

• Institutional capital: BlackRock, Fidelity, Grayscale—companies that don’t invest in “fads,” but in long-term trends.

• New use cases: crypto & blockchain now serve not just finance, but logistics, energy, gaming, and digital ownership (NFTs, tokenization).

Mining in energy:The biggest shift has been here. Miners aren’t just “machines printing crypto” anymore. Today, mining:

• helps balance the grid—switching on when power is cheap or oversupplied,

• acts as the exact flexible load renewables need,

• supports RES growth—by giving new value to energy that isn’t worth selling.

So is it a “trend”?If something lasts over a decade, involves the world’s largest financial institutions, and finds use in energy—hardly. It’s an evolving sector adapting to reality.

💡 Cryptocurrencies aren’t a hipster fad. They’re infrastructure for the future—already connecting finance and energy today.

Conclusion

Mining with RES isn’t a niche curiosity. It’s a practical tool that lets you:

• turn cheap or excess electricity into digital assets,

• support the grid instead of burdening it,

• replace myths with actual tech and profit.

The key is matching the model to your situation:

• hybrid system with storage—for large-scale business,

• simple surplus usage—for homeowners.

It’s up to the investor: stay stuck in myths, or seize the opportunity.
