Elon Musk: ‘You can’t fake energy.’ Has Bitcoin finally gone green enough for Tesla?

Elon Musk lately revived the “51 % renewables” benchmark, stating that the power backing Bitcoin “can’t be faked.”

The reference is to his earlier promise that Tesla would resume accepting Bitcoin funds as soon as not less than half of mining power got here from clear or low-carbon sources.

However, now that the most recent knowledge suggests the community could have crossed that threshold, Tesla nonetheless hasn’t re-enabled BTC checkout. Why?

Has Bitcoin handed the bar but?

According to the Cambridge Centre for Alternative Finance’s 2025 Digital Mining Industry Report, sustainable power now powers roughly 52.4 % of surveyed Bitcoin mining exercise.

Of that, 42.6 % is from renewables (hydro, wind, photo voltaic, and so on.) and 9.8 % from nuclear or different low-carbon sources. In parallel, fossil gas contributions have shifted: pure gasoline now accounts for 38.2 % (up from ~25 % in 2022), and coal has fallen to eight.9 % (down from ~36.6 %).

If Musk’s promise is taken actually, Bitcoin could already exceed the 51 % “sustainable power” bar, not less than as measured by Cambridge’s survey of corporations that cowl roughly 48 % of worldwide mining capability.

But that is solely half the story. The wording issues: Musk has referenced renewables (50 %) in earlier feedback, although in later tweets he says “51 % renewable” or “power you can’t fake.” The Cambridge determine lumps renewables + nuclear; the pure renewables share is decrease (42.6 %).

So, BTC should fall quick relying on the rigidity of Musk’s definition.

Moreover, the Cambridge method is survey-based and covers solely a subset of miners. Off-grid operations, curtailed renewables, regional idiosyncrasies, and temporal mismatches (when renewables produce roughly relative to mining demand) complicate the image.

Alternate fashions, comparable to these primarily based on grid carbon depth or power tracing, usually yield extra conservative estimates of renewable share. That divergence means even a nominal “move” is topic to debate.

So why hasn’t Tesla flipped the change?

Even granting that Bitcoin could now qualify underneath Musk’s sustainability check, Tesla has not re-enabled BTC funds. Several pragmatic and symbolic hurdles stay.

The first is due diligence. Musk beforehand said that Tesla would solely restart funds as soon as he noticed “cheap (~50 %) clear power utilization … and a pattern towards rising that quantity.” That wording implies he’s trying for persistence, not a one-off knowledge level.

A single report displaying 52 % sustainable power could not fulfill his requirement for a verified and sustained upward pattern in Bitcoin’s power combine.

Another issue is definition readability. Tesla would want to determine whether or not “sustainable” consists of nuclear and low-carbon sources or strictly renewables like hydro, wind, and photo voltaic. The Cambridge knowledge combines these classes, however Musk’s earlier phrasing referenced renewables particularly.

Without a universally accepted definition, any choice to renew BTC funds dangers being accused of greenwashing.

There can also be the difficulty of service provider and market threat. Accepting Bitcoin exposes Tesla to cost volatility, advanced accounting therapy, and potential regulatory problems.

Even if the corporate instantly converts BTC receipts to fiat, fluctuations between order placement and settlement introduce monetary uncertainty that is probably not well worth the effort for a automotive producer working on skinny margins.

Brand optics add one other layer. Tesla’s picture is constructed on environmental credibility, and even a minor backslide in Bitcoin’s power profile may set off backlash from buyers and ESG-minded prospects. The firm could desire to err on the facet of warning slightly than face renewed criticism if mining exercise shifts again towards fossil-heavy areas.

Finally, operational integration can’t be ignored. To carry Bitcoin funds again on-line, Tesla would want to rebuild pockets infrastructure, transaction pipelines, and conversion mechanisms. That requires engineering sources and inner approvals: steps which might be removed from trivial for a worldwide producer already balancing a number of product launches and software program initiatives.

Taken collectively, these components counsel that clearing the 51 % renewable threshold just isn’t enough by itself. For Musk, the check appears to be as a lot about confidence, consistency, and notion as about uncooked knowledge. Until these align, Tesla’s checkout web page is prone to keep crypto-free.

What this implies for adoption

From a story standpoint, Musk’s reengagement wields affect. If Bitcoin can credibly cleave to a cleaner power combine and main industrial counterparts like Tesla start transacting once more, it might reinforce a extra sustainable narrative for crypto.

Yet Tesla’s continued off-chain standing regardless of claims suggests Musk views the promise as conditional, not automated. The check is as a lot about optics, threat management, and narrative as it’s about easy metrics.

For now, Bitcoin’s claimed “51 %+ sustainable” standing affords a compelling rebuttal to critics, however till checkouts return, it stays extra of a symbolic win than a industrial one.
