“At least 90% of new electricity generating capacity planned for addition in the United States in 2026 is from solar, wind, or battery storage.”

True 9/10

This claim is true. According to the U.S. Energy Information Administration's February 2026 data, solar (51%), battery storage (28%), and wind (14%) together account for 93% of the 86 GW of planned utility-scale capacity additions in 2026 — comfortably exceeding the 90% threshold. These figures are corroborated by multiple independent energy publications. The data reflects planned additions as currently reported and could shift slightly as projects are updated, but the 3-percentage-point margin above 90% makes a drop below that threshold unlikely.

“Frequently charging a smartphone battery to 100% accelerates battery degradation compared to charging to lower levels.”

Mostly True 8/10

The claim is directionally accurate: peer-reviewed research confirms that higher state-of-charge accelerates lithium-ion battery degradation through well-understood mechanisms like SEI growth and lithium plating. Real-world smartphone tests also show measurably better capacity retention when charging is capped below 100%. However, the claim lacks important context: modern phones use battery management systems that reduce stress near full charge, and the practical effect over a typical phone's lifespan is often modest — not dramatic. The biggest factor is time spent at high charge levels, not simply reaching 100%.
