The Electric Grid Needs Huge Upgrades by Katherine Blunt & Jennifer Hiller

The U.S. power industry is embarking on an AI-driven expansion of the electric grid, a build-out that promises to be one of the most expensive since World War II. Utilities around the country are planning to spend tens of billions of dollars to build new high-voltage transmission lines to carry electricity from power plants over long distances. Many companies this year announced plans to substantially increase capital expenditures to build the new capacity, in large part to serve demand from data centers. The White House this month announced that seven of the nation’s largest tech companies had agreed to pay for all the costs associated with powering new data centers.

Google to Invest $40B in AI Data Centers, Workforce Training Across Texas by Claire Hao, James Osborne

Google plans to invest $40 billion into artificial intelligence data centers and related workforce training across Texas through 2027. That includes plans to build three new data centers – two in Haskell County and one in Armstrong County. It’s the latest massive investment from tech giants racing to surpass each other in the development of artificial intelligence. Amid this rush, Texas has emerged as one of the most attractive states for new data centers, given its ample land, relatively cheap electricity for large industrial users and abundant energy resources.  Google to invest $40B in AI data centers, workforce training across Texas

Trump Sets 100% Chip Tariffs Unless Firms Invest in U.S.

President Trump said he would impose roughly 100% tariffs on all chips coming into the U.S. but exempt tech companies that have promised to manufacture domestically, a big win for Apple and other electronics firms worried about new trade challenges. Trump’s announcement came at an event trumpeting a new $100 billion investment pledge from Apple. The company has increased its commitments in the U.S. but stopped short of moving iPhone production to the U.S. as Trump wants. The company’s $100 billion promise adds to a $500 billion, four-year commitment Apple made in February that repackaged much of Apple’s existing spending plans in the U.S. Nearly every major tech firm has promised to put more into their U.S. operations, resulting in over $2 trillion in new pledges in the past seven months. f16AjRmObp1pmp4xDQAH-WSJNewsPaper-8-7-2025.pdf

The AI Data-Center Boom Is Coming to America’s Heartland by Jennifer Hiller

Meta and other tech companies are scouring rural America for land, transmission lines and natural gas. Meta Platformsscooped up 2,700 acres of farmland last year for what would be its largest-ever data center, built over flat rice fields 45 minutes west of the Mississippi River.  At 4 million square feet, or 70 football fields, Meta’s data center will cost $10 billion and sit on more acreage than Louisiana State University in Baton Rouge, which has more than 34,000 students. Building advanced artificial-intelligence systems will take city-sized amounts of power, which has turbocharged electricity demand projections for the first time this century. The AI Data-Center Boom Is Coming to America’s Heartland – WSJ

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.
