Renewable Energy Could Power 70% of Bitcoin Mining Activities by 2030

A new report published by risk metrics data platform Nodiens predicts that, based on the trajectory of renewable energy growth in bitcoin mining, renewable energy could power 70% of bitcoin mining activities by 2030, CryptoSlate reported.

This year, the MiCA Crypto Alliance stated that in 2011, roughly 20% of the industry's activities were powered by renewable energy. By the end of 2024, this number doubled.

“The composition of renewable energy has diversified over time,” the report read, per CryptoSlate.

Bitcoin uses a proof-of-work consensus mechanism, according to Forbes, which requires computers to solve complex math problems to verify transactions.

This high-demand computational process uses a significant amount of energy that strains grids. On top of that, multiple bitcoin miners race to solve the equations as quickly as possible to earn small rewards. The effort exerted by the “losers” is essentially rendered futile, with the energy consumed also wasted.

The energy that bitcoin mining gobbles up increases as more miners compete for the same math problems and as more bitcoin transactions occur.

In 2011, bitcoin mining consumed only 0.002 terawatt-hours of energy, per the MiCA Crypto Alliance. In 2024, this figure increased to approximately 140 TWh. Polytechnique Insights said that the annual electricity consumption of bitcoin mining is comparable to that of the country of Poland.

The increased demand for energy could also raise retail electricity rates because suppliers may need to source more energy to supply consumers during peak demand times.

The industry has made an admirable effort to transition industry operations to renewable energy sources, thereby reducing the environmental impact of crypto transactions. However, most crypto transactions are still largely powered by dirty fuels, contributing to planet-heating gases.

Bitcoin mining hardware also becomes obsolete every year and a half, according to Digiconomist, producing an annual total electronic waste comparable to "the small IT equipment waste of the Netherlands." Each bitcoin transaction produces an average e-waste of 375.5 grams, equivalent to the weight of 2.29 iPhone 12s.

As cryptocurrency shifts to a more green-dominant energy industry, the sector must make a greater effort to address the e-waste problems that mining creates as well.

If you have e-waste at home, consider recycling your technology with companies such as Apple, Best Buy, Target, and Trashie, which have recycling programs to better manage unused or unwanted electronics.
