Renewable Energy - Optimistic Storm

Electricity for AI exceeds transporation

Electricity for AI Exceeds Transportation

AI computing’s surge outpaces electricity demand for transportation, potentially exceeding it due to expansive training and inference needs. Massive datacenters from tech giants necessitate immense power, raising speculation about electricity shortages. Tesla leads with significant investments in low-power and high-performance chips, aiming for exascale AI capabilities. This growth in AI computation could increase datacenter electricity use fourfold within a decade, challenging current power grids and possibly requiring dedicated power plants to meet escalating energy demands.

Chinese Coal Drops from 70 to 45 Percent by 2030

Lauri Myllyvirta forecasts China’s coal dependency to drop from 70% to 45% by 2030, influenced by renewable expansions and energy policy shifts reported in April 2024. Despite local-global energy strategy conflicts and bureaucratic hurdles, China’s renewable energy sector is flourishing with vast solar and wind installations, and plummeting solar, battery prices. China’s energy security challenge is compounded by coal quality issues and reliance on imports.
