Energy and sustainability
Mining is the only industry that can run anywhere, switch off instantly and needs no supply guarantee. Those properties make the energy debate more interesting than the cliché.
Flexible demand as a grid service
Because miners can curtail within seconds, some grids use them as controllable load: off during scarcity, on during surplus.
That can make wind and solar projects viable that otherwise lack a buyer of last resort.
Reusing waste heat
All electricity consumed leaves as heat. In Northern Europe it heats districts, pools, drying processes and greenhouses.
Heat recovery changes the maths: effective energy cost falls by the value of displaced heating.
- Curtailed wind and solar
- Captured gas instead of flaring
- Waste heat for buildings and processes
European rules ahead
Under MiCA, crypto service providers must publish information on the climate impact of consensus mechanisms; large data centres face energy and water reporting duties.
For miners this means documented power sourcing becomes a condition for working with professional counterparties.
Najczęstsze pytania
How much power does bitcoin use?
Estimates move with hashrate and efficiency and sit in the order of a few tenths of a percent of global electricity use.
Is green mining greenwashing?
Not when the power would otherwise be curtailed; yes when it crowds out other users of scarce green capacity.
Does mining consume water?
Air-cooled setups barely; immersion and water cooling do, often in closed loops.

What is crypto mining?
Mining explained without jargon: why networks need computation, what a miner does and where the reward comes from.
Halving and mining economics
Every four years the block reward halves. What it does to margins, hashrate, hardware cycles and the role of fees.
Proof-of-work versus proof-of-stake
Two ways to secure a network. What they cost, which attacks they deter and why the debate is rarely about technology.
