At the turn of the millennium, more than 80% of Australia's electricity came from coal. Over the following decades that share fell below 45% as solar and wind power expanded rapidly. Australia has abundant sun and wind, and rooftop solar in particular spread into millions of homes. The change reshaped the country's grid, which must now balance variable renewable output with storage and backup. Our World in Data uses the trend to show how quickly a major coal-dependent economy can shift its power mix. The data highlights a transition that was far faster than many forecasts anticipated.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
