Energy + Environment

  The Claim On July 2nd, US DOE’s Office of Critical Minerals and Energy Innovation (that replaced the shuttered EERE) sent out an email stating, “U.S. Secretary of Energy Chris Wright today announced the Department of Energy (DOE) has issued a Notice of Proposed Rulemaking to permanently end home appliance and equipment mandates that raise [...]

  Surging utility rate cases, accelerating load growth, and eroding public trust are converging into a critical inflection point for the U.S. power sector. In the first quarter of 2026 alone, utilities filed $9.4 billion in rate-hike requests, underscoring the scale of capital recovery now flowing through regulatory pipelines. Yet this wave of filings arrives [...]

  A new class of photonic radiative cooling (PRC) coatings is advancing from laboratory research into viable commercial products, offering a passive pathway to reduce building heat loads without electricity. These coatings are engineered to reflect the vast majority of incoming solar radiation while simultaneously emitting heat through the Earth’s atmospheric window, enabling surfaces to [...]

    By Szymon Slupik, President & CTO, Silvair Energy saving is the primary feature of lighting control systems. The concept is well known: dim the lights if there is enough sunlight (daylight harvesting controls) or turn the lights off when there are no people in the room (occupancy / vacancy – based controls). The [...]

  Researchers at CU Boulder have developed a way to make living algae emit light for much longer than the tiny flashes seen in nature, opening the door to electricity-free lighting and other “living material” applications. The team used simple chemical solutions to trigger sustained bioluminescence in Pyrocystis lunula, an algae embedded  in 3D-printable hydrogel [...]

  An interesting article in US Lighting Trends compares the economics of diesel vs. solar construction site light towers. The article argues that while diesel light towers remain the familiar default for construction jobsites, solar-powered area lighting is becoming a more compelling option as owners and contractors prioritize lower emissions, quiet operation, and long-term cost [...]

  A large number of states either have passed or are considering mandatory battery recycling laws, known as “extended producer responsibility,” or EPR laws for batteries. These laws can impact lighting manufacturers that include handheld remote controls or potentially stand alone smart control components containing batteries. By 2027, more than 61 million Americans will live [...]

  I’ve previous written two articles (1) & (2) about a startup that is seeking to reflect sunlight onto Earth with a constellation of giant space mirrors. That startup, Reflect Orbital, based in California, plans to deploy up to 50,000 orbiting mirrors by 2035 to provide $5,000/hour “sunlight on demand” for solar farms (also to [...]

  As of March 3rd, 2026, the EPA is transferring the ENERGY STAR program to the Department of Energy (DOE) through a 10-year Memorandum of Agreement. This shift, driven by a desire to unify labeling with DOE’s efficiency standards, initiates a 90-day transition period for transferring partnerships, IT systems, and databases. Key Details of the [...]
