Italian energy giant Enel has announced a massive €53 billion investment plan spanning 2026 to 2028, with a primary focus on expanding its renewable energy and grid infrastructure activities across Europe and the United States. The company also formalized an 830MW US wind and solar portfolio acquisition.

Geothermal energy is experiencing a breakout moment, with a string of legislative victories, new drilling technologies borrowed from the oil and gas industry, and a growing roster of tech companies signing power purchase agreements. The long-overlooked renewable is finally getting its due.

The cost of long-term renewable energy contracts rose 9% in 2025 and is expected to continue climbing as data centers, manufacturing reshoring, and electrification drive unprecedented electricity demand. Energy storage agreements have emerged as the fastest-growing segment of the clean energy market.

A new report finds that Massachusetts can meet its 2050 peak electricity demand entirely without combustion-based generation, relying instead on a mix of renewables, storage, and demand response. The finding challenges the long-held assumption that gas peaker plants are indispensable for grid reliability.

A study of more than 5,000 home sales found that properties with owned solar panels sold for 5-10% more than comparable homes without them. The premium translates to $39,500 to $79,000 in added value, though leased systems showed no consistent benefit.

University of Surrey researchers have discovered that keeping water in sodium-ion battery cathodes nearly doubles their energy storage capacity. The counterintuitive finding upends conventional wisdom that water must be removed from battery materials during manufacturing.

Hydrostor's 500-megawatt compressed air facility in California and a wave of new storage technologies are making coal power economically obsolete faster than policy can revive it.
