U.S. Renewable Energy Patent Trends (2015–2025): A Snapshot from PatSeer Analytics
Renewable energy has surged in the U.S., reaching 24% of total electricity generation in 2024, with solar and wind leading the transition. But which renewable technologies are truly advancing in innovation? A PatSeer -based patent landscape study (2015-mid-2025) reveals a striking contrast between market deployment and patent activity. Using the CPC category Y02E10 , covering solar, wind, geothermal, hydro, and marine energy, the analysis shows: Key Patent Filing Trends Photovoltaics dominate with 3,200+ filings, far outpacing all other sectors. Wind energy has the fewest patents despite contributing heavily to real-world power generation-signaling maturity rather than lack of innovation. Thermal-PV hybrids, marine, and geothermal show early-stage but promising patent traction. Top Innovators Established firms like Halliburton , Schlumberger , and Saudi Aramco are extending their drilling expertise into renewable segments. Me...
