The United Nations reports a global shift toward renewable energy, calling it a "positive tipping point." Tuesday's U.N. reports reveal that 92.5% of new electricity capacity in 2022 came from renewables, with wind and solar leading the way. Renewables like solar and wind are now significantly cheaper than fossil fuels, driving investment to $2 trillion last year. However, officials warn the transition is not happening fast enough, especially in regions like Africa. Despite booming renewables, fossil fuel production continues to rise due to increasing energy demands. U.N. Secretary-General Antonio Guterres calls on tech firms to power data centers completely with renewables by 2030.

After the Palisades and Eaton fires scorched entire neighborhoods, the Army Corps of Engineers set up operations to recycle concrete and metal from mostly fire-damaged homes. Tons of these everyday materials are washed where they're collected, loaded onto trucks, and sent to begin the recycling process. For example, metal is compacted and concrete is crushed, then shipped to recycling facilities before re-entering the supply chain for future uses. In the world of planet-warming emissions, making fresh concrete and steel are major contributors to climate change, and industry experts say recycling is a good way to rebuild more sustainably.

 President Donald Trump and Sen. David McCormick of Pennsylvania are touting tens of billions of dollars of energy and tech investments at a new summit focusing on energy and innovation. "This is a really triumphant day for the people of the commonwealth and the United States of America," Trump said Tuesday as he took the stage at the summit. Pennsylvania is a swing state critical to Trump's wins in 2016 and 2024, and is at the forefront of his energy agenda. On a panel discussion, Commerce Secretary Howard Lutnick said the Trump administration won't let the U.S. lose the artificial intelligence race. Participating companies at the conference include Blackstone, Bridgewater, SoftBank, Amazon Web Services and ExxonMobil.
