Renewable capacity growth in the United States during 2025 sent a mixed signal. Solar still added substantial capacity, battery storage set a higher annual mark in the research record, and wind additions improved from 2024. At the same time, policy changes narrowed tax-credit timelines, added permitting pressure for some projects, and reduced the certainty that developers had relied on after the Inflation Reduction Act.

The useful reading is not that federal policy stopped clean power development in 2025.… Read the rest

U.S. clean energy capacity continued to expand through the first half of 2026, with the strongest evidence pointing to solar and battery storage as the main sources of near-term growth. The direction is clear in the planning data: developers expected to add about 86 gigawatts of new utility-scale electric generating capacity in 2026, with solar accounting for 51% of planned additions, battery storage 28%, and wind 14%, according to the EIA capacity outlook.… Read the rest

Clean energy projections are often discussed through headline capacity targets, but capacity alone does not show whether low-carbon electricity will arrive fast enough, connect to grids, or avoid avoidable environmental damage. The available evidence as of mid-2026 points to real growth in renewables, especially solar PV and wind, while also showing constraints that can make projection-based planning too optimistic if those constraints are treated as minor details.

In 2023, global renewable capacity additions reached a record 510 GW, and solar PV and wind accounted for 96% of that growth.… Read the rest

Imagine a world where energy flows smoothly, like a jazz melody. Pumped storage is the unsung hero of our power grid. It ensures the lights stay on when demand peaks.

It’s like the backup singer you didn’t know you needed. It harmonizes with renewable sources like wind and solar. Together, they create a symphony of stability.

But what is this energy wizardry? Simply put, it stores excess energy by moving water to an upper reservoir.… Read the rest

The EPA’s May 11, 2026 proposal on data center energy infrastructure did not approve new emissions by itself, but it changed a key permitting question: what project work can begin before a major air-emissions permit is secured. The agency proposed redefining “Begin Actual Construction” under the Clean Air Act so that data centers, gas plants, and factories could build non-emitting components such as wiring, cement pads, and piping before receiving major air permits, according to the EPA proposal.… Read the rest

As of September 14, 2026, clean energy additions planned for the year point to a record-setting period for U.S. power-sector construction, led by solar and battery storage. The data should be read with care: planned capacity is not the same as completed capacity, and the power-system effect depends on interconnection, permitting, market conditions, and how reliably new resources operate once connected.

The near-term signal is still significant. The U.S. Energy Information Administration reports that developers plan to add 86 gigawatts of new utility-scale electric generating capacity in 2026, which would be a record if realized.… Read the rest

For renewable energy teams, grid-scale storage is no longer a side issue attached to wind and solar planning. Recent reviews show fast battery deployment, a clear shift toward lithium-iron phosphate chemistry, and continued questions about duration, cost, siting, safety, and market design. The evidence supports a practical reading: storage is expanding quickly, but no single technology fits every grid service.

Battery systems now lead new storage additions by power capacity, especially where grids need short-duration flexibility, renewables integration, and fast response.… Read the rest

Long-Duration Energy Storage sits at the center of a practical grid question: how can a power system with much higher renewable generation maintain reliability during long gaps in wind or solar output? The evidence available on September 9, 2026, supports a cautious answer. Storage with longer discharge duration may reduce the need for some fossil generation, but its role depends on cost, siting, market rules, and whether projects can provide dependable service at grid scale.… Read the rest

As we get closer to 2026, the world of renewable energy is changing fast. The cost per watt is dropping, trying to see how low it can go. At the same time, records for solar efficiency are being broken, like a Tesla reveal.

But there’s even more happening. India plans to add over 165 GW of solar module capacity by 2027. This could lead to a market flood and a fight for profits.… Read the rest

U.S. battery storage has moved from a supporting technology to a major part of the power-sector buildout. The most useful way to read that growth is not as a simple win for reliability, but as a measurable change in how the grid can absorb renewable generation, respond to short-term demand swings, and manage periods when solar or wind output falls.

The recent numbers are large enough to matter. They also need careful interpretation.… Read the rest
