What’s New with Solar in the United States?

April 25, 2025

  • Solar energy continues to lead U.S. power generation growth, with projections indicating that solar and battery storage will comprise 81% of new capacity additions in 2025, totaling approximately 63 gigawatts. ​
  • In the first two months of 2025, solar and wind accounted for 98% of new U.S. electricity capacity, with solar representing nearly 75% of that growth. ​
  • The U.S. power system achieved a milestone in March, with clean energy sources generating 51% of all utility-scale electricity, marking the first time renewables surpassed the halfway point. ​
  • Texas is leading the nation in solar expansion, with 11.6 GW of new installations expected in 2025, followed by California with 2.9 GW, and significant contributions from Indiana, Arizona, Michigan, Florida, and New York. ​
  • Despite a 60-day suspension of renewable energy permits on federal lands earlier this year, the U.S. has resumed permitting for solar and storage projects, though challenges remain due to staffing shortages and tax credit uncertainties. ​
  • In Houston, the first Tesla-powered residential community has launched, featuring homes equipped with solar roof tiles, Powerwall batteries, and EV chargers, highlighting a growing trend toward sustainable housing solutions. ​
  • Houston also unveiled plans for the “Arch of Time,” a $20 million solar-powered sculpture that will function as the world’s largest freestanding sundial, generating more electricity than the park’s annual consumption. ​

Ryan Holtz

Owner & Off-Grid Specialist

Ryan graduated from West Point with a degree in Mechanical Engineering.

Ryan got started by studying with Solar Energy International and the Solar Living Institute. He loves developing and sharing solar technology. Ryan has taught solar energy classes at Coconino Community College, Willow Bend Environmental Center and all around Arizona. Some of Ryan’s favorite moments in solar work are watching a solar customer’s meter spin backward for the first time, and providing solar power to Navajo and Hopi families living off-grid who have never had electricity in their homes.

One of Ryan’s main goals is to make solar energy accessible to everyone by offering solar options that are affordable and easy to use. He acknowledges there are some hurdles to widespread solar energy use, but believes that with a little ingenuity like the Plug and Play Solar Kits, it will soon become a normal part of everyone’s daily life.

In his free time, Ryan is often outdoors. He enjoys mountain biking, running, disc golf, hiking and camping.  His favorite thing to do is sit around a campfire with his wife, Carolyn, and their dog Tully.

Jim Corning

Founder

Jim Corning’s professional life revolves around aviation, energy, and engineering. He was a student at MIT in the 1970s, and saw firsthand how the oil shortages of the ‘70s plunged our country into a place of scarcity. Since then, he has worked in the oil industry on the Arctic coast, built electric motorcycles, organized sustainable living fairs, taught classes on solar electric systems, and helped Ryan Holtz start up Prometheus Renewables. Jim’s goal is to help Americans find a way to energy abundance, and it gives him great pleasure to see Prometheus’ clients harvesting their own clean solar power, right at home.

When Jim charges his Chevy Volt with solar power, he enjoys the abundance of driving on sunshine. It’s very liberating.

When he’s not working, Jim loves hiking, mountain biking, flying and backpacking around the beautiful mountain west with his wife Holly.
