LEDs Gain Ground in Controlled Environment Agriculture Space by Tim Kridel

William Attardi on April 10, 2026

Key Takeaways

  • LED lighting has shifted from niche to mainstream in controlled environment agriculture, driven by improved spectrum, output, and cost reductions.
  • Energy efficiency of LEDs allows growers to achieve higher light levels with less power, enabling cost savings and increased crop productivity, especially in high-value sectors like cannabis.
  • Dynamic spectrum control enhances crop quality and yield by allowing growers to customize light recipes for different growth stages, improving nutritional density and shelf life.
  • Utility rebates and incentives significantly offset the higher upfront costs of LEDs, making them a financially attractive option for growers investing in long-term infrastructure.
  • LEDs’ lower heat output impacts HVAC and humidity management, creating new opportunities for electrical contractors to optimize greenhouse climate control systems.

Those are just a few examples of artificial lighting’s role in controlled environment agriculture (CEA) facilities, which include greenhouses, warehouses, vertical farms, and even caves. The CEA market will grow from nearly $10 billion this year to $27.7 billion by 2035, Business Research Insights estimates. LED lighting is helping enable that growth. LEDs Gain Ground in Controlled Environment Agriculture Space | EC&M

Energy Star’s Move to DOE Helps It Escape Proposed EPA Cuts

William Attardi on April 10, 2026

The Trump administration for the second year in a row is calling for elimination of the Office of Atmospheric Protection inside the U.S. Environmental Protection Agency, but the Energy Star program, which has been part of the office for 30 years, is positioned to escape the cut; since November, the program has been operating out of EPA’s Office of Radiation and Indoor Air and, starting in June, will be moved out of EPA entirely. Under an agreement EPA signed with the U.S. Department of Energy last month, DOE will take over administration of the program. The administration says the office isn’t needed and shutting it down will save the government $100 million.  Energy Star’s move to DOE helps it escape proposed EPA cuts | Facilities Dive

The Rise of Supply Chains That Adapt by Professor Jeannette Song

William Attardi on April 10, 2026

Professor Song explains how AI is turning supply chains from rigid workflows into adaptive, decision-making systems. When you click “buy now” on online stores, recommendations appear, warehouses spring into action, and packages begin their journey to your door. Behind that seamless experience is a fundamental transformation. Supply chains, once governed by fixed rules and human planning, are becoming AI-driven systems that learn, adapt, and increasingly act on their own. In her book chapter, Reshaping Supply Chains Through AI-Empowered Automation, Jeannette Song, the R.David Thomas Professor at Duke University’s Fuqua School of Business argues that AI is fundamentally changing how supply chains work.“AI is reshaping supply chains in four connected ways: expanding automation across the chain, changing how humans and machines work together,” she said, “raising new questions about privacy and accountability, and pointing toward a future of more autonomous, agentic systems.” The Rise of Supply Chains That Adapt

Construction Jobs Increase in 38 States Year-Over-Year

William Attardi on April 10, 2026

Construction employment rose in 38 states from January 2025 to January 2026, while 40 states and the District of Columbia added jobs between December and January, according to an analysis of new federal data released by the Associated General Contractors of America. Association officials called on policymakers in Washington to provide adequate support for training to enable workers to acquire in-demand skills and to allow qualified workers into the U.S when needed workers are not available. View January 2026 state employment data and 1-month, 12-month rankings.  Association officials noted that the industry has a critical need for electricians and other workers with the skills to construct data centers and power projects. They urged the federal government to direct more funding to career and technical education and workforce training and to offer a pathway to employ needed workers from other countries.   Construction Jobs Increase in 38 States Year-Over-Year – tEDmag

LiteTrace Introduces Bluetooth Wall Switch with Integrated Occupancy Sensor and Dimming

William Attardi on April 8, 2026

The Keilton+autani IWS102/DWS102 by LiteTrace Brands transforms standard wall switches into intelligent control hubs that manage both hardwired lighting and networked devices based on occupancy, without requiring ceiling-mounted sensors or fixture modifications. Unlike typical occupancy sensors that only control their hardwired load, the IWS102/DWS102 offers dual control architecture: hardwired occupancy-based switching for connected lighting plus wireless Bluetooth control of additional networked loads. The integrated 4-button interface provides manual dimming and On/Off control while occupancy functions operate independently. A single wall-mounted sensor orchestrates lighting and equipment control across an entire room through the Keilton+autani Bluetooth network, including plug load controllers (WF20R) for appliances and equipment. Ideal for conference rooms, private offices, lunch rooms, storage areas, copy rooms, and restrooms where coordinated lighting and equipment control maximizes energy savings.

Manufacturers Test AI-Translation Tech to Improve Worker Communications

William Attardi on April 7, 2026

To more effectively communicate with workers who speak little to no English, a growing number of U.S. manufacturers are leveraging translation technologies driven by artificial intelligence. They are also using real-time translation tools to improve safety and compliance with regulatory standards. Manufacturers employ roughly 1 million foreign-born workers, representing about 20% of the industry, according to 2024 U.S. Census Bureau data.

The Statue of Liberty was made with copper but due to oxidation, it turned green.

When the “Lady in the Harbor” first arrived in New York in 1886, she didn’t look like the mint-green icon we know today. In fact, for the first twenty years of her life, she stood as a towering, metallic beacon of reddish-gold. Designed by French sculptor Frédéric Auguste Bartholdi and engineered by Alexandre Gustave Eiffel, the statue was a gift from France to America. To build her, Bartholdi chose copper for three practical reasons:

  • Malleability:It could be hammered into elaborate, thin sheets.
  • Weight:Copper is lighter than stone or bronze, making it easier to ship 350 individual pieces across the Atlantic.
  • Durability:It was strong enough to survive a 27-day ocean voyage and the harsh winds of the harbor.

When she was unveiled on October 28, 1886, her skin—made of 300 copper sheets roughly the thickness of two pennies—shone with a bright, metallic brown luster. The transformation from “penny-colored” to “patina-green” wasn’t planned. Bartholdi actually expected the statue to age into a deeper, darker red. However, the unique environment of New York Harbor—a mix of salt air, moisture, and industrial pollution—triggered a process called oxidation.

The Timeline of Change:

  1. 1886–1900:The bright copper dulled into a dark, muddy brown.
  2. 1903:The first hints of a light green crust, or “patina,” began to appear.
  3. 1906:The color change was so controversial that Congress nearly stepped in. They appropriated $62,000 to paint the statue back to its original color, but the public protested, calling the idea “sacrilege.”
  4. 1910–1920:The statue was a patchy mix of brown and green until 1920, when the oxidation was complete, leaving her entirely teal.

While we now view the green color as iconic, it actually serves a vital structural purpose. The layer of verdigris (the green patina) acts as a protective shield. It seals the copper underneath, preventing the metal from further corrosion and weathering.  By the time the color fully changed, a new generation of immigrants had arrived in America seeing a green statue.
