Musk Warns AI Chip Boom Could Trigger 15GW Power Shortfall
Elon Musk says computers used for artificial intelligence may need more electricity than the world can provide.
He warned that there could be a large power shortage by 2027.
AI chips are being made much faster than new electricity capacity is being added outside China.
Musk thinks countries that build more power plants could attract AI data centers.
These centers could bring investment and tax money.
He also believes AI may soon become better than people at writing software.
Musk predicted that AI could add trillions of dollars to the global economy.
He further predicted that more than one billion humanoid robots could exist within 10 years.
Elon Musk warned G20 economies that AI could create a significant electricity shortage as early as next year.
He cited estimates of at least a 15-gigawatt power shortfall for AI chips in 2027.
Musk said AI chip production is growing 40–50% annually, while power capacity outside China rises 10–20%.
He argued that countries expanding electricity generation could attract AI data centers, investment, tax revenue and hosting fees.
Musk also predicted rapid AI advances, a $20–30 trillion annual economic boost and more than one billion humanoid robots within 10 years.
