Clean Energy Booms as Mining and Storage Gaps Persist

A Sector Growing Faster Than Its Critics Expected

Clean energy is expanding at a pace few predicted even a few years ago, but its rapid rise is exposing structural weaknesses that could slow the transition if left unaddressed. Renewable capacity, once a marginal contributor to global power supplies, has become a mainstream force in energy markets over the past two decades, and new generation capacity is projected to grow by a record 45 gigawatts this year alone, according to S&P Global Energy data cited in recent reporting 3. That growth is notable given political headwinds in the United States, where efforts by the Trump administration to slow clean energy development have largely failed to blunt momentum in the sector 3.

The Mining Bottleneck

Despite this growth, the industry faces a persistent and increasingly urgent problem: the mineral supply chain underpinning batteries, turbines and solar panels. Commentary on the issue argues that responsible mineral development and robust environmental protection should not be framed as opposing priorities, pushing back on the idea that faster permitting must come at the expense of environmental safeguards 1. This tension sits at the center of a broader debate over how quickly the U.S. and other nations can scale up domestic mining and processing of critical minerals like lithium, cobalt and nickel without repeating the environmental harms associated with legacy extractive industries.

Storage and Intermittency Remain Unsolved

Beyond mining, technical limitations continue to constrain how much clean energy can realistically displace fossil fuels. Solar and wind power remain inherently intermittent, and current lithium-ion battery technology is not yet capable of storing enough renewable energy to reliably meet demand around the clock 2. That gap has spurred interest in a wider range of experimental approaches, including geothermal energy and tidal power projects that developers hope could eventually diversify the clean-energy mix and reduce reliance on weather-dependent sources 2.

Fusion and Quantum Computing Enter the Picture

Longer-term solutions are also advancing on the research side. IBM has reported a breakthrough in fusion energy research made possible by applying quantum computing to a challenge that has stymied scientists for decades 5. While fusion remains commercially unproven, developments like this signal that next-generation energy technologies are drawing serious investment and computational firepower, potentially reshaping the clean-energy landscape further out.

Policy Still Matters at the State Level

Even as federal politics create uncertainty, state-level policy continues to shape the pace of deployment. In New Jersey, Governor Phil Murphy signed legislation aimed at advancing the state's clean-energy targets, a move framed as a significant step toward growing the state's renewable energy industry 4. Such state actions illustrate how, even amid national political friction, subnational governments continue to push the transition forward, reinforcing the sense that clean energy's growth is now driven by multiple, overlapping forces rather than any single federal policy.
