Next Texas Energy Boom: Solar

Layzej writes: The Wall Street Journal reports: "Solar power has gotten so cheap to produce—and so competitively priced in the electricity market—that it is taking hold even in a state that, unlike California, doesn't offer incentives to utilities to buy or build sun-powered generation." Falling cost is one factor driving investment. "Another reason for the boom: Texas recently wrapped up construction of $6.9 billion worth of new transmission lines, many connecting West Texas to the state's large cities. These massive power lines enabled Texas to become, by far, the largest U.S. wind producer. Solar developers plan to move electricity on the same lines, taking advantage of a lull in wind generation during the heat of the day when solar output is at its highest."

    So when the economics make sense, investments follow, without the need for governments to step in and choose winners and losers. Who'd have guessed?

    That's true. But it's ALSO true that government subsidies can accelerate the development of practical cost-effective technologies, by getting them scaled up earlier.

    Well, I drive through a lot of massive wind farms in Texas a lot and that land usually IS being used.

    Usually for agriculture. Lots of cotton, corn, soybeans, cattle, etc. are raised around turbines.

    BINGO! The West Texas plains were a boon to wind prospectors. Every energy company with any renewable aspirations bought/leased a patch of land and threw up a wind farm. Just one problem...nobody lives in West Texas. It's open range for hundreds of miles. The very conditions that made wind possible left a very real problem. All that electricity needed to get to Dallas but the power line to Dallas was at capacity. All those wind turbines producing electricity and nowhere to send it. Storage tech was prohibitively expensive (If electricity is selling for $0.09 kWh storing it at $0.10 kWh doesn't make financial sense.) so into the earth all that electricity went. So ERCOT set out to build more capacity around 2008. Those lines went live in 2013. Combine that with technology making CSP even cheaper and you've got the next gold rush on your hands.

    Full disclosure, I work for Nextera Energy. Parent company of Lone Star Transmission who operates a stretch of those transmission lines.

    What happened to fibreglass cars? They used to the next big thing, no rust etc.

    Too easy to damage, too hard to repair. Even Aluminum is easier than fiberglass, you just weld in a new section. Also, a fiberglass body is just landfill when you're done with it, aluminum or steel is highly recyclable — aluminum actually moreso, because the resulting alloy is more similar to what you started with. Recycled steel is brittle. We used to make cars out of mild steel here and then when they got crushed they would make them into harder steel and make Japanese cars out of them. Now we make cars out of hard steel too, and when they get crushed, they make dishwashers and shipping containers. But Aluminum cars will just get made into more cars.

    Aluminum is more of a PITA to repair than steel, but no plan is perfect.

    We don't use space frames wrapped in non-structural body panels because that's an inefficient use of space. It's cool for a race car but doesn't make much sense for a street car. You can only really build a sports car that way, which is why only sports cars are (or were) built that way; Corvette, some Ferraris, etc.
