Bitcoin’s energy consumption has sparked a heated debate, with critics condemning its environmental impact and supporters asserting its eco-friendliness. But which side is right?
The global imperative to combat climate change by curbing carbon emissions cannot be overstated. Hence, it’s no surprise that Bitcoin, a cryptocurrency known for its substantial energy usage, faces intense scrutiny. Regrettably, the ongoing discourse often leans towards bias, relying on selective arguments and perpetuating misconceptions. To gain a comprehensive understanding, it is essential to delve into why Bitcoin requires energy, the nature of the energy it uses, and the potential societal advantages it may offer.
Why does Bitcoin need so much energy?
One prominent aspect of the ongoing debate revolves around a lack of clarity regarding why Bitcoin consumes such a significant amount of energy. To put it simply, the majority of this energy isn’t dedicated to processing and storing transactions; instead, it is used for a resource-intensive competition aimed at determining the entity entitled to create a new block of transactions. This competition arises from the prospect of receiving freshly minted Bitcoin as a reward, thereby fostering a greater willingness to invest in energy resources, particularly when the value of Bitcoin appreciates.
However, this appreciation is counteracted by a process known as “halving,” which occurs every four years and reduces the reward. The aim of the mining process is to enhance the network’s security. Shifting to a less computationally demanding approach for block creation, a possibility demonstrated by Ethereum’s blockchain, would fundamentally transform Bitcoin’s decentralisation and core philosophy, making it an unlikely scenario.
The critics: Carbon emissions and funding of illicit activities
In discussions concerning Bitcoin’s energy usage, critics often hone in on two main issues: the extensive energy consumption and the consequent carbon emissions associated with creating new transaction blocks. While the overall energy consumption remains a point of agreement, it’s vital to note that the energy mix – whether it relies on fossil fuels or renewables – varies significantly depending on the country and region. This factor significantly influences the environmental consequences. Detractors of Bitcoin commonly argue that the cryptocurrency holds no intrinsic value and is frequently employed by terrorists and money launderers.

The supporters: The path to economic freedom and environmental benefits
Supporters of Bitcoin contend that claims of the cryptocurrency facilitating illicit activities are easily debunked due to its pseudonymous nature. This feature results in publicly accessible and immutable traces, rendering it unattractive for criminals. Moreover, they point out surprising environmental benefits associated with Bitcoin, such as incentivizing the use of renewable energy sources and offering the capability to stabilise the grid by enabling easy activation and deactivation of Bitcoin mining activities. Lastly, they underscore Bitcoin’s potential to replace segments of the traditional, energy-intensive financial system, creating a democratic payment alternative that promotes financial inclusion and individual, and possibly national, economic independence.
The future: A long and winding road ahead
The adoption of Bitcoin for practical purposes, like payments, has been slow to gain global traction, though it has seen gradual growth over the years. In 2024, it appears that the traditional financial industry is increasingly accepting its former adversary. The recent approval of Bitcoin Exchange-Traded Funds (ETFs) by the U.S. Securities and Exchange Commission (SEC) could potentially reshape the overall narrative. Notably, this development isn’t universally embraced within the original Bitcoin community, with concerns raised about potential reductions in Bitcoin’s decentralisation and departure from its original philosophy.
As a consequence, the discussion surrounding Bitcoin’s energy consumption may diminish in public discourse, given that both individual and institutional investors now have a convenient means to invest in the cryptocurrency. However, the current situation also presents numerous opportunities to hold the community accountable and develop innovative solutions promoting renewable energy use, grid stability, and a positive environmental impact. Achieving this may necessitate cooperation from significant stakeholders such as mining companies and increased transparency regarding energy sources.
The comprehensive debate surrounding Bitcoin encompasses a multitude of arguments, both in favour of and against its use. A fair evaluation requires careful consideration of both sides, taking into account practical applications and potential benefits. In theory, Bitcoin has the potential to replace a significant portion of the existing financial system and support individuals previously excluded from it.

Matumizi ya nishati ya Bitcoin imesababisha mjadala mkali, na wakosoaji kukataza athari zake za mazingira na wafuasi kudai urafiki wake wa mazingira. Lakini ni upande gani ulio sahihi? Lazima ya kimataifa ya kupambana na mabadiliko ya hali ya hewa kwa kuzuia uzalishaji wa kaboni haiwezi kuzidiwa. Kwa hiyo, si ajabu kwamba Bitcoin, cryptocurrency inayojulikana kwa matumizi yake makubwa ya nishati, inakabiliwa na uchunguzi mkali. Kwa kusikitisha, mazungumzo yanayoendelea mara nyingi huelekea kwenye upendeleo, kutegemea hoja za kuchagua na kudumisha dhana zisizo za kweli. Ili kupata uelewa kamili, ni muhimu kuchunguza kwa nini Bitcoin inahitaji nishati, asili ya nishati inayotumia, na faida za kijamii zinazoweza kutolewa. Kwa nini Bitcoin inahitaji nishati nyingi? Jambo moja muhimu la mjadala unaoendelea ni ukosefu wa uwazi kuhusu kwa nini Bitcoin hutumia kiasi kikubwa cha nishati. Kwa maneno rahisi, sehemu kubwa ya nishati hii haitumiki kwa usindikaji na kuhifadhi shughuli; badala yake, hutumiwa kwa mashindano ya rasilimali yenye lengo la kuamua chombo kinachostahili kuunda block mpya ya shughuli. Ushindani huu unatokana na matarajio ya kupokea Bitcoin mpya kama thawabu, na hivyo kukuza utayari mkubwa wa kuwekeza katika rasilimali za nishati, haswa wakati thamani ya Bitcoin inathamini. Hata hivyo, tathmini hii ni kukabiliana na mchakato unaojulikana kama <unk>halving,<unk> ambayo hutokea kila baada ya miaka minne na hupunguza tuzo. Lengo la mchakato wa madini ni kuongeza usalama wa mtandao. Kubadilisha kwa mbinu ya chini ya kompyuta ya kudai kwa ajili ya block uundaji, uwezekano alionyesha na Ethereum blockchain, ingekuwa kimsingi kubadilisha Bitcoin ya decentralization na falsafa ya msingi, na kufanya hivyo uwezekano wa hali. Katika majadiliano kuhusu matumizi ya nishati ya Bitcoin, wakosoaji mara nyingi huongeza juu ya masuala mawili makuu: matumizi makubwa ya nishati na uzalishaji wa kaboni unaofuata unaohusiana na kuunda vitalu vipya vya shughuli. Wakati matumizi ya jumla ya nishati bado ni uhakika wa makubaliano, ni muhimu kutambua kwamba mchanganyiko wa nishati - kama inategemea mafuta ya fossil au nishati mbadala - inatofautiana sana kulingana na nchi na mkoa. Jambo hilo huathiri sana athari za mazingira. Wasifu wa Bitcoin kwa kawaida wanasema kuwa cryptocurrency haina thamani ya ndani na mara nyingi hutumiwa na magaidi na wafuaji fedha. "Kutathmini ya athari za mazingira za Bitcoin ni ngumu zaidi kuliko watu wengi wanavyofahamu. ""Wanaunga mkono: Njia ya uhuru wa kiuchumi na faida za mazingira"" Wafuasi wa Bitcoin wanadai kwamba madai ya cryptocurrency kuwezesha shughuli haramu ni rahisi debunked kutokana na asili yake ya pseudonymous." Kipengele hiki husababisha alama zinazopatikana kwa umma na zisizoweza kubadilika, na kuifanya isiwe yenye kuvutia kwa wahalifu. Kwa kuongezea, wanaonyesha faida za kushangaza za mazingira zinazohusiana na Bitcoin, kama vile kuhamasisha matumizi ya vyanzo vya nishati mbadala na kutoa uwezo wa kudumisha gridi kwa kuwezesha uanzishaji rahisi na ufutaji wa shughuli za uchimbaji wa Bitcoin. Mwishowe, wanasisitiza uwezo wa Bitcoin kuchukua nafasi ya sehemu za mfumo wa kifedha wa jadi, unaotumia nishati nyingi, na kuunda mbadala wa malipo ya kidemokrasia ambayo inakuza ujumuishaji wa kifedha na uhuru wa kiuchumi wa mtu binafsi na labda wa kitaifa. """Baadaye: Barabara ndefu na yenye mteremko mbele ya kupitishwa kwa Bitcoin kwa madhumuni ya vitendo, kama vile malipo, imekuwa polepole kupata traction ya kimataifa, ingawa imeona ukuaji wa hatua kwa hatua kwa miaka." Katika 2024, inaonekana kwamba sekta ya kifedha ya jadi inazidi kukubali mpinzani wake wa zamani. Uteuzi wa Bitcoin Exchange-Traded Funds (ETFs) na Tume ya Usalama na Soko la Marekani (SEC) ni hatua ya kwanza katika kuimarisha uaminifu wa Bitcoin. Hasa, maendeleo haya si ulimwenguni kote kukumbukwa ndani ya jamii ya awali Bitcoin, na wasiwasi juu ya kupunguzwa uwezekano katika Bitcoin ya decentralization na kuondoka kutoka falsafa yake ya awali. Kama matokeo, majadiliano yanayozunguka matumizi ya nishati ya Bitcoin yanaweza kupungua katika mazungumzo ya umma, kwa kuzingatia kwamba wawekezaji wa kibinafsi na wa taasisi sasa wana njia rahisi ya kuwekeza katika cryptocurrency. Hata hivyo, hali ya sasa pia inatoa fursa nyingi za kushikilia jamii kuwajibika na kuendeleza suluhisho za ubunifu zinazohimiza matumizi ya nishati mbadala, utulivu wa gridi, na athari nzuri ya mazingira. Kufikia hili kunaweza kuhitaji ushirikiano kutoka kwa wadau muhimu kama vile makampuni ya madini na kuongezeka kwa uwazi kuhusu vyanzo vya nishati. Mjadala wa kina unaozunguka Bitcoin unajumuisha hoja nyingi, kwa niaba na dhidi ya matumizi yake. Tathmini ya haki inahitaji kuzingatia kwa uangalifu pande zote mbili, kwa kuzingatia matumizi ya vitendo na faida zinazowezekana. Kwa nadharia, Bitcoin ina uwezo wa kuchukua nafasi ya sehemu kubwa ya mfumo wa kifedha uliopo na kusaidia watu binafsi ambao hapo awali walikuwa wameondolewa. Treblmaier, H. (2023).
