IEA September data update shows solar supplied a record 22.5% of OECD Europe electricity in June
The IEA’s September 16 monthly update reports 285.1 TWh of net generation in OECD Europe during June 2026. Solar produced 64.0 TWh, or a record 22.5% share, while Spain, Türkiye and France recorded the largest absolute year-on-year increases.
White House ratepayer pledge lists Bitdeer and sets five rules for data-centre power costs
Bitdeer appears among data-centre signatories to the White House Ratepayer Protection Pledge. The framework says large facilities should procure added supply, pay delivery upgrades and special rates, invest locally and support resilience. It is a public commitment, not a substitute for tariffs or permits.
Energy Economics study models a Bitcoin “productivity trap” for efficiency gains
An open-access Energy Economics paper argues that more efficient mining hardware can expand equilibrium resource use without increasing Bitcoin output. Its model also finds that surplus renewables may cut emissions while increasing hardware turnover, and evaluates a global Pigouvian tax as a policy response.
