Next Texas Energy Boom: Solar 327

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."

    If I felt so inclined, I'm sure I could dig up post-upon-post from previous slashdot stories about how unlikely solar (and wind) power is to take off in any meaningful way, and how electric cars will never be a thing. We are just at the beginning, and the economic incentives took only a few year to become reality. I'm guessing that is due in no small part to subsidies paving the way for investment and growth that so many complained about. An industry, and really a way of life, is slowly being built from the ground-up. It's pretty exciting to watch!

      I just wish people would hold other people accountable for their rank hypocrisy. Here's another commercial example... Chevy has aluminum trucks coming in 2018 but they're slagging Ford for selling them right now. What astonishing douchebags. But people will just buy those trucks in a few years...

        Yeah. In the car industry that is pretty standard. I think it was Ford who was a year or two behind on the dual sliding doors on minivans and ran ads about how unsafe that was... until theirs was available. And the execs rotate around and they use different ad companies so they can all blame it on the last guy if anyone does ask.

          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.

      Considering most of the well priced solar panels are coming from China these days, are these government subsidies being sent over there? That definitely would be something to complain about.

    There's something I've never understood here.

    if you have land for wind power, why would you not want solar spread around it in the safety zone of the tower? Same lines can carry all of the power. Lower real estate cost. Why is it that I only ever see or hear about a solar farm or a wind farm and never an energy farm?

    Maybe someone here more familiar with the topic can help me out, or tell me that it's being done and just not talked about much.

      There are some drawbacks to colocating wind and solar:

      - It's not always the case that a single parcel of land is optimal for both wind and solar

      - Wind turbines will cast shadows onto the solar panels if placed together, reducing the solar panels' output somewhat

      Which isn't to say that placing both together isn't a good idea, only that there are some tradeoffs. I suspect that doing them separately also keeps the projects simpler to implement on both the regulatory and technical sides.

    • The viability of solar and wind are highly dependent on geography. Just like you wouldn't build a hydroelectric dam in the desert, there are specific areas which are prime for solar and wind. Building solar or wind outside of those locations represents lower energy production for the same cost, so it's preferable to use that money to build elsewhere. The wind farms tend to get built where there's the most wind. The solar farms tend to get built where there's the most sunshine. It's pretty much only the

    Wind turbine generation is such shit. If you have a lot of constant, unending wind, it seems like a good idea; typically, solar outclasses it by far.

    My analysis of solar has changed in the past month. I last looked half a decade or so ago, when the ROI for solar was 19 years; it's now 2.5 years. Seriously. What the fuck? The arrays are more efficient, and they're down from like $3.84/W for shit-efficiency panels that degrade rapidly to $1.81/W for high-efficiency panels that degrade by less than 0.7% per year and are guaranteed to have above 80.7% efficiency 25 years into their lifespan--with god damn microinverters and advanced monitoring systems. When did this shit happen? I can generate 9,800kWh/year with optimal placement, 9,200kWh/year with simple placement, and thus about $1500 of electricity and $1700 of SRECs.

      ...as evidenced by the great many solar-installations being built at sea.

      • They're some of the least-efficient plants. A few at 37 acres/MW, some at 100+ acres/MW.

        There's actually a comparison of land usage for a nuclear power plant as a wind farm or solar farm [entergy-arkansas.com].

          Yeah, my observation is that land-usage by windfarms is going away, as countries are now placing them at sea - meanwhile, I've not heard of any "oceanic solarfarms", and I'm thinking spray and saline might work against that concept.

          • Off-shore wind farms, as I've said, cost twice as much per unit power generated as solar. Solar's land usage is much smaller (2%-13%, depending on who you ask).

      Wind energy is still the cheapest renewable out there with research continuing at a breakneck pace. Solar will likely out-compete one day but wind still has the advantage of being a potential 24hr generator as well as not needing such large battery backups systems since downtime is more likely to only be a few hours as opposed to 12 or more with solar. As wind energy reaches higher and higher altitude winds, their consistency continually increases to the point where inflatable models promise the potential
      • The problem is output per area. Large solar installations use 8 acres per MW, with the sun only out for part of the day, and varying insolation per year; while large wind installations use, at the extreme, 14 acres per MW. Wind average is 85 acres per MW; the most efficient are 14, 23, 25, 29, 30, 37, and so forth. There are a handful under 50 acres per MW, and many over 100, some as high as 300 acres per MW.

        As for the fluffy argument, solar is predictable for the whole year; wind is not.

          That's only a problem for solar. Most of the land under a turbine can still be used for agriculture.

          As for predictable, wind in Texas is very predictable and available far more than sunshine.

          • You can't pack wind turbines closely together to create a dense, purposed wind farm. To produce a wind farm, you must secure mineral rights (the mineral being wind) to an enormous land area--say, 300,000 acres instead of about 13,000. That means you must either lease the right to use the footprint of the windmill, or dual-purpose your farm. Farm equipment can't just roll clear through a wind turbine, so will need to navigate around the turbine; this means more labor, and possibly difficult problems if t

        • That is a reasonable argument, but consider that a nuclear plant is closer to 8 acres per GW, and that is 1GW 95% of the time, not some pitiful fraction of renewable nameplate capacity. Together, these factors give nuclear a footprint many thousands of times less than renewables. Please, let us not pave the world to harvest the sparse energy of wind and the sun, when there are better alternatives.

      How many GOP Texans were screaming about how solar, wind and other renewables were nothing but communist liberal bullshit and yet.. here we are.

      This is classic misunderstanding of Republican ideals. They're not against renewables per se. They're against subsidizing the sale of technologies which can't self-support themselves. If/when the technology is able to compete economically on its own with existing technologies, they are more than happy to use it.

      The error is actually in the environmentalists' thinking. They support wind and solar unconditionally regardless of cost. They then assume everyone else thinks like they do. Since the GOP opposed wind and solar in the past, they erroneously assume the GOP must oppose wind and solar unconditionally. (I narrow it down to environmentalists because most of the people on the left are aware of cost constraints.)

      In fairness, there is a non-monetary cost associated with pollution which many GOPers leave out. But if you factor that in, then nuclear ends up being the best choice of power source at present. And most environmentalists oppose nuclear so I can't give them credit for correctly factoring in pollution costs.

    While taking over a desert to lay out a giant solar power farm, roof top units are probably more ideal. A large portion of power is lost through transit. I have heard calculations from 65% to 84% of power produced being lost from generation to the time where a device is powered. I don't much care for those kind of losses. Smaller and distributed sources of power generation help to create a more robust power grid.

  • Lord, give us one more boom. We promise not to piss it away this time.
  • Yes PV solar plant are becoming less expensive if they dump all their power directly to the grid. If they are required to have a storage system so that they can base production on demand rather than supply the costs rise greatly. A molten salt plant is much more expensive to build and maintain than a field of PVs. Otherwise we get conventional plants that ramp way down during the day and back up at night. Both those ramps waste a lot of money and CO2.

    More thought and money needs to go into storage. I don't

    • Demand is generally higher during the day, so at least for a while this will mean a less variable demand on other supplies, not more.

      Moving water up hills (or not letting it down -- letting hydro reservoirs fill up) is quite a good storage option on this scale.

      Demand can also be shifted to some extent. You can within certain limits, choose when to cool a refrigerated warehouse, or charge an electric car. I imagine tarifs that make electricity cheap in the few hours after dawn and expensive in the few hours

      • Demand is generally higher during the day, so at least for a while this will mean a less variable demand on other supplies, not more.

        That is true until the daytime solar production approaches total daytime demand. Previously, base demand is supplied by coal and other slow ramping systems. During the day this base load supplies about 50% and almost 100% at night. The ramp up for daytime demand was handles by faster ramping systems such as gas and hydro. The problem comes when solar makes up for more than 50% of daytime usage. Without storage one would start ramping down the conventional production to make room for the solar production. It
