Key Terms

renewables technical

"These investments span new additions to the company's renewables portfolio, upgrades..."

Renewables are energy sources that are naturally replenished over short time spans—like sunlight, wind, flowing water, and plant-based fuels—used to generate electricity, heat, or fuel. For investors, renewables matter because they represent a shifting energy mix with long-term demand potential, often requiring big upfront investment but offering predictable operating costs and exposure to government policies and incentives; think of them like a rechargeable power supply replacing one-time fuels.

natural gas power plants technical

"portfolio, upgrades to its natural gas power plants, storm hardening efforts..."

Natural gas power plants are facilities that burn natural gas to produce electricity, using turbines or engines that drive generators much like a car engine turns wheels. They matter to investors because their profits depend on two moving parts—how much they can sell electricity for and how much fuel costs—so changes in gas prices, demand for electricity, or energy policies can quickly affect earnings and the value of companies that own or operate them.

green hydrogen technical

"tested the nation's first system capable of producing, storing and using 100% green hydrogen."

Green hydrogen is hydrogen made by splitting water with electricity that comes from renewable sources, producing little or no carbon emissions. Investors watch it because it can act like a rechargeable, low‑carbon fuel or energy carrier for industries and transport that are hard to electrify, creating long‑term demand for production plants, storage and transport infrastructure and making returns sensitive to technology costs, energy prices and policy support.

self-healing technology technical

"Self-healing technology has also expanded, preventing more than 215,000 hours of outages..."

Self-healing technology is material or system design that can automatically repair damage—like cracks in a surface, broken circuits, or software bugs—without human intervention. For investors it matters because products that fix themselves can lower repair and warranty costs, extend useful life, and boost reliability, similar to a car that patches its own tire, which can translate into stronger margins, steadier revenue and a competitive edge in markets that value durability.
