Often, when I get depressed, I scan for articles about developments in solar, wind, tidal, geothermal, and other kinds of renewable energy generation. Good news seems to be easily found in these areas. My brain is tired, so I'm just sharing links to these six articles without my usual pictures, analysis, attempts at humor, and wit, to see if I can get started today before it is time for bed.

The Economist reports A way to double the efficiency of solar cells is about to go mainstream.

SUNLIGHT is free, but that is no reason to waste it. Yet even the best silicon solar cells—by far the most common sort—convert only a quarter of the light that falls on them. Silicon has the merit of being cheap: manufacturing improvements have brought its price to a point where it is snapping at the heels of fossil fuels. But many scientists would like to replace it with something fundamentally better.

John Rogers, of the University of Illinois, Urbana-Champaign, is one. The cells he has devised (and which are being made, packaged into panels and deployed in pilot projects by Semprius, a firm based in North Carolina) are indeed better. By themselves, he told this year’s meeting of the American Association for the Advancement of Science, they convert 42.5% of sunlight. Even when surrounded by the paraphernalia of a panel they manage 35%. Suitably tweaked, Dr Rogers reckons, their efficiency could rise to 50%. Their secret is that they are actually not one cell, but four, stacked one on top of another. ...

Dr Rogers gets round this by using a different material for each layer of the stack. He chooses his materials so that the bottom of the band gap of the top layer matches the top of the band gap of the one underneath, and so on down the stack. Each layer thus chops off part of the spectrum, converts it efficiently into electrical energy and passes the rest on.

Dr Rogers has overcome the cost barrier of the expensive materials needed for these "tuned" semi-conductors by placing them in a matrix of half a millimeter wide dots covered with a larger array of cheap glass lenses which focuses light from a much larger surface area onto the smaller more expensive photovoltaic material. This article is filled with brilliant production engineering innovation details for the more interested reader.

Kiley Kroh, of Think Progress reports that 99 Percent Of New Power Generation Added In January Came From Renewable Energy


More than 99 percent of new electric capacity added in the U.S. in January came from renewable energy sources, according to data released by the Federal Energy Regulatory Commission (FERC) on Thursday.

Of the 325 megawatts of new capacity installed, solar led the way with 287 megawatts added in January. That was followed by geothermal power with three new units totaling 30 megawatts, one new unit of wind energy with an installed capacity of 4 megawatts, and three new units of biomass totaling 3 megawatts. In addition, there was 1 megawatt added that FERC defined as “other.” ...

Big picture aside, the immediate renewable energy trend is clear. January’s noteworthy numbers mirror those from several months last year — in November, 100 percent of the 394 megawatts of new capacity added came from renewable sources. In October, 699 megawatts were added, 99 percent of which came from renewable sources. And in March, 100 percent of new electrical generation capacity came from solar, as seven units with a total combined capacity of 44 megawatts were added.

From Micheal Freeman, of The Orlando Sentinel, we learn, New solar panels heating up energy in Winter Park.

It’s now official: Winter Park has installed its rooftop solar panels at the Public Works Compound at 1409 Howell Branch Road, making the city a trailblazer in the use of solar energy as a way to deliver electricity to residents.

The city’s electric utility director, Jerry Warren, used Valentine’s Day to show off the new solar photovoltaic panels, calling it “a huge step for the city as it relates to entering into a more sustainable energy source.” ...

This project, developed by Clean Footprint and ESA Renewables – a solar company that’s also based in Florida -- generates 100 kilowatts of energy. ... This has become the city’s first, largest and only solar energy project to date.

On a less encouraging note, Market Watch informs us that
The world’s ‘dumbest trade war’ is being fought over solar panels.

 

The “world’s dumbest trade war” is the spat between the U.S. and China over solar panels, according to an article on Slate. But it’s not just dumb: it could threaten the future of solar power, the online magazine says.

Cheap and plentiful solar panels from China have fueled the boom in rooftop solar systems. But now that the U.S. is threatening to slap new tariffs on them, China could retaliate by slapping more duties on U.S. manufactured polysilicon, a key component of the panels, the article says.

It all started when the U.S. division of Germany’s SolarWorld AG started lobbying the federal government for an investigation on alleged duty evasion. The Chinese Ministry of Commerce followed with a call to stop the probe, asking the U.S. government to be “prudent” in taking any further measures.

Lauren Williams, of Think Progress, asks Could A Solar-Powered Currency Be The Next Bitcoin? Oddly, enough, I find this article a little depressing, as well, since it reminds me that there are several aspects about this whole "Bitcoin" phenomena that I still don't understand even after several smart Kossacks have explained it to me.

A new digital currency that rewards solar panel users could not only encourage more people to switch to solar energy but provide a new, more stable model for future alternative currencies.

SolarCoin debuted last month and builds on the same technology as Bitcoin — the popular cryptocurrency most notable for attracting an online criminal element. Like Bitcoin’s decentralized model, anyone can get SolarCoins by buying them via Twitter or helping create digital coins through mining. What separates the two is that instead of relying on mining, which involves solving complex math puzzles, SolarCoins are incentives for homeowners who use solar panels.

Consumers earn SolarCoins just by using the solar panels installed on their home or business. SolarCoin checks solar homeowners’ meters to verify that they are producing solar energy and rewards them with coins. That passive approach, where consumers can simply earn money just by doing something they believe in, could be what makes the new currency more sustainable than other alternative currencies.

The more they try to explain it, the more confused I get. For example:

Still, at minimum, SolarCoin, which says its model is 50 times more energy efficient than Bitcoin, is an altruistic way for renewable energy advocates to show support and grow the solar community, Honeyman said. “The good thing is that there’s a huge opportunity for homeowners,” apartment complex owners and those who aren’t solar generators to contribute to the cause, Honeyman said.

No matter how much I concentrate today, I don't have even the slightest clue about what this means. I do find it slightly amusing, and encouraging, that my lack of understanding doesn't prevent me from writing about it anyway. This proves the old adage, "if at first you don't succeed, lower your standards."

From AgriNews, we read Huge thermal plant opens as the industry grows

The Ivanpah Solar Electric Generating System, sprawling across roughly five square miles of federal land near the California-Nevada border, is formally opening after years of regulatory and legal tangles ranging from relocating protected tortoises to assessing the impact on Mojave milkweed and other plants.

The $2.2 billion complex of three generating units, owned by NRG Energy Inc., Google Inc. and BrightSource Energy, can produce nearly 400 megawatts — enough power for 140,000 homes. It began making electricity last year. ...

Using technology known as solar-thermal, nearly 350,000 computer-controlled mirrors roughly the size of a garage door reflect sunlight to boilers atop 459-foot towers. The sun’s power is used to heat water in the boilers’ tubes and make steam, which drives turbines to create electricity.

Well, I hope you found this interesting.

9:56 PM PT: Thanks to New Minas for explaining the artistic aspect of this new kind of solar photovoltaic. Because of the way the light is absorbed by the solar cells, artwork can be printed on them without interfering with their efficiency. I skipped this beautiful picture in the original post because I thought it was just a gratuitous pix. Only now do I realize it was one of the most interesting aspects of the article.

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc).

  •  Love it, HoundDog. I've been interested in solar (25+ / 0-)

    ever since I saw its power in a garage we converted to living space in NM. Garage faced almost due south and we built an indoor planter approx 20" high, then bay windows to the top of the garage door frame. Room was uninsulated, touched the house on 2 walls and was absolutely the warmest place in the house on winter mornings before the furnace took over. My kids used to dress for school in that room.

    I figured we could get a lot of our heating needs met simply by siting a house with a good southern exposure, sufficient glass and some sort of heat sink in the floor. NM is, of course, ideally suited for solar heating. Plenty of sun virtually all year for plenty of passive gain opportunities. Nice to see the technology is advancing. It will be interesting to follow this new development. Thanks for posting!

      great idea.

      Someone told me once that he planted deciduous trees around his house to keep the heat off in the summer, but to let the heat in in the winter. I can't remember the details, but he did something to his roof, to help absorption of heat in the winter.

      A lot of houses were built long ago when energy costs were so low no one really thought about it. But, now this kind of creativity can have a worthwhile "return on investment."

        shade in summer. Also a fairly deep overhang on southern windows will provide summer shade and allow winter passive gain as the sun is at a lower angle in winter than in summer. The people who built Mesa Verde used this to their advantage.

        There's a neighborhood in Davis, CA that built with solar in mind in the 70's (iirc). The developer made sure every house had adequate southern exposure (the streets ran east/west) and there were ordinances adopted that prevented owners from planting trees that would block their neighbors' solar access. It's high time every developer/builder started adopting these practices.

        •  and trees don't only shade the house. In summer, (13+ / 0-)

          surprisingly large amounts of water pass through trees and evaporate from the leaves ("evapotranspiration"), cooling the air in the process far beyond simply blocking the sun. The scale of it? Roughly a hundred gallons of water through one full-grown tree on a hot, dry day. That's a lot of free air conditioning. Trees actually cool the planet.

          Of course you need trees to have that happen, and for there to be large trees, you need lots of water - rain, mist, fog, snow, etc. Wherever you see large trees, think: there's lots of annual rain, or at least moisture, here. I say that last because the largest trees in the world, the giant sequoias, are supplied almost constantly, not with rain, but with mist and fog.

          I have a very large red oak, well over a hundred years old, on the south side of my house. Shade and evaporative cooling in the summer, and sunshine through the bare branches in winter.

          This is not a new discovery. People who had to cut firewood by hand thought lots about which trees to save and how to site a house to take advantage of the sun and the lay of the land. You put activities, driveways, etc., on the south side (in the northern hemisphere) rather than the darker, damper, icier north side. When Papa Lippy built our house  after WWII, he sited it with deciduous trees to the south and the driveway and everyday door on the south.

            laying out the house you live in. Amazing what a little planning will do, no?

            I knew that trees give off water on hot, dry days. Didn't realize it was, potentially, such a large amount. Fat chance they're losing 100 gallons in NM given the extreme drought there. My brother lives in a rural NM area. His property is approx 1/2 mile from the Pecos River. He waters his fields from an irrigation ditch, but the dam from which the ditchwater comes was broken for approx 6 years, so the 100-year-old cottonwoods on his property had to survive on rain/snow for that period. Even his proximity to the river didn't protect a large number of them. Can't remember how many he lost, but a high percentage of them. Upside was that he had plenty of firewood.  

            I have a small piece of land in NM that I always wanted to build on. I've spent many hours thinking about orientation of house, floorplan, location of trees/garden/etc. I wish developers would give a little thought to those things and that city planning offices would adopt requirements to take advantage of solar opportunities. Guess we'll have to work to elect local officials who actually believe in science. ;-)

  •  good news (13+ / 0-)

    I'm all for more efficient panels.

    We've used Sanyo, which has a multi-layer approach too.  They get an effective 20% or maybe a little better, but the price differential means they are not really cost effective.

    Right now we can get good quality made in the USA )Solar World) for about a buck a watt.  

    Except for some tactical systems (military etc) the size and space effectiveness is less important than the dollars per watt.  Most of our systems, the solar panel is now down the list in terms of cost. Batteries and other electronics you have to have are more expensive.

      •  Premium priced for a while yet (9+ / 0-)

        Price is what matters. The higher efficiency means that they will generate more power per unit area than other commercially available photoelectric systems. They will be able to command a higher price, because customers with limited space will pay more.

        These panels have to precisely track the sun, so you can't just slap them on a roof and walk away. On the other hand, they make more power, so the complexity is offset.

        The fact that they can charge a premium price is good, because they will need a lot of money to scale up their factories to build these in volume. If things go very well, in a few years, these will only be a little more expensive than other photovoltaic options. However, if you don't need to maximize power per square meter, there will be cheaper (but larger) alternatives.

    and FWIW I don't get bitcoins either. What can you buy with a bitcoin? Who accepts bitcoins as currency? When Amazon starts accepting them to pay for my ebooks, then they will be something tangible. Until then they look like just a new form of tradable commodity that is totally contingent on people believing they have value (unlike pork bellies which actually do (for example)).

    However it's very cool that we might be on the cusp of a major leap in renewable energy efficiency. If this pans out and can be manufactured cheaply it might be the death of coal.

    The truly awesome thing about renewables is what they mean for the future. My personal prediction is that inside of a few decades (max) people will be able to use their 3D printer to make a bunch and stick them to the sides of their homes and basically energy becomes free at that point in time. That's going to have massive repercussions for the current economy and the economic model in general. It's also going to change the world forever...

    It has been controversial and (some) environmentalists have fought it tooth and nail, but it is a great technology because it is a solar thermal plant that has the potential to generate power when the sun isn't shining anymore from the residual heat.  The next generation of this technology is also coming online in smaller plants using molten salt, which is a pretty darned good replacement for "baseload" power.

    That's kind of a holy grail kind of thing.

      of this breakthrough is the cost, not smaller footprint, but they are related.

      The materials needed to capture the energy in these different band gaps is very expensive.  So greatly reducing the amount needed to these little dots, and using inexpensive glass lenses to focus light on the smaller dots means less expense, not total surface area of the complete collector.

      What this article does not discuss is how he has solve the heat generation problem. Many previous innovators have thought about this idea of using glass lenses or reflectors to concentrate the light to smaller surface area solar collector but the problem is that the efficiency of traditional photovoltaics is inversely proportional to temperature, especially over 100 degrees F.  

      Perhaps, the significance of the specific materials he is using is the solution, the article is not clear.

          This is the funniest opinion on anything to do with finance that I have ever read.

    The new panels have aesthetic advantages, too. The 99.9% of them not covered by stacks can be used for art. Seen from the sun’s point of view (ie, straight ahead), they appear black because the lenses are focused on the stacks, which absorb all the light falling on them. Viewed obliquely, however, their foci are on other parts of the panel. The result, as the picture shows, can be quite pleasing—and certainly prettier than a coal-fired power station.

    They claim to convert 35, 42, and possibly 50% of sunlight. From what I understand, that's about 2 to 3 times more efficient than massroduced panels. They also claim that the dots cover only about 0.1% of the panel surface area. That means you give up a factor of 1000 in surface area. Ok, lenses, then you get back the factor of 500 to 1000 without making the panels more expensive or less robust?

        Each layer captures a different wavelength range. For example:

        Sunlight
        ----------  800 nm collection layer
        ----------  650 nm collection layer
        ----------  500 nm collection layer
        ----------  400 nm collection layer

        There's wiring in small channels between each layer. This can be a more efficient method of collection because each layer has a higher collection efficiency for that wavelength range than a single layer silicon cell would.

        The problem is making them big. Let's say that about 1000 W/m^2 of sunlight reaches the earths surface (yes, this varies with location, weather, etc. but 1000 is a simple number to start with). If you have a panel that is 20% efficient! you can collect 200W. If only 90 of the panel area is covered by cells, you collect 180 watts.
        For these cells, you have 50% collection efficiency giving you a potential collection of 500W. The problem is that you have a panel coverage of 0.1%, that means you only collect 0.5W. Now, if you use lenses maybe you can increase effective panel collection coverage to say 60%. This gives about 300W, but now you have the added cost of fairly large lenses over the whole panel.

        How cheap and rugged are the lens compare to standard solar panel covers? How much of the sunlight do the lenses absorb and convert to heat? How do the efficiency of the multilayer cells stand up to increase temperature and how does that affect the lifetime of the cell?

        I can't expect answers to those questions in a fluff piece, but we should temper our expectations accordingly.

  •  Windmills Can Neutralize Hurricanes (4+ / 0-)
    Recommended by:
    HoundDog, Skyye, cheminMD, ozsea1

    According to Stanford engineering professor Mark Z. Jacobson, a large array of offshore windmills could neutralize oncoming hurricanes:

    wind turbines could disrupt a hurricane enough to reduce peak wind speeds by up to 92 mph and decrease storm surge by up to 79 percent.

    He says 78,000 windmills offshore in the Gulf would have weakened Katrina's wind to a typical rainstorm's and storm surge down from about a dozen feet to about 3 feet. Sandy would have been a thunderstorm with an annoying but manageable flood.

    Offshore windmills can cost up to 20 $million each, so 78,000 would cost $156 BILLION. But that's at full cost for a new technology and very small volume production - 78,000 in even one farm would probably cost less than 1/4 of that. Katrina and Sandy cost (coincidentally) $82 BILLION each.

    In addition to taming hurricanes, the windmills could generate power most of the time between them. And perhaps the peak during the storms would generate really vast energy while destroying these monsters.

    I'm all for doing every sustainable thing we can to retire our suicidal energy industry legacy. But this is the first I've heard that can replace devastating consequences of that legacy with loads of power immediately with the same intervention.

    For less than we spent bailing out AIG we might have the reversal of the Greenhouse within our lifetimes. That is the kind of good news I crave as antidote for the politics that seems all too sustainable.

        The effect of these large windmill arrays operates on the unique dynamics of high-speed circular storms over warm water: hurricanes. Besides, they don't block an inflow of air; they slow it when it's at very high speeds in a critical link of a hurricane's self-amplification chain. I see no evidence that weather outside that narrow, devastating configuration is changed by this configuration.

        Nor any evidence from existing windmills that they affect weather at all. The humid Gulf air wouldn't just disappear, or even be deflected to anywhere else. Just that the exceptional spikes in hurricanes would meet enough resistance that they'd be disrupted instead of being perpetuated into a hurricane.

  •  Not Such a Dumb Trade War (2+ / 0-)
    Recommended by:
    HoundDog, Skyye
    The “world’s dumbest trade war” is the spat between the U.S. and China over solar panels

    That trade war isn't so dumb. China is dumping solar panels in the US below even China's manufacturing cost. It's put the US solar panel manufacturing industry to the brink, along with some of the rest of the US solar equipment manufacturing industry - and threatened EU and other industry by doing it. Of course once the competition is broken the Chinese will jack up their prices. And the US will have lost the industry it created, nearly before it got started.

    China won't just gouge the US market. It will, without competition, probably not increase efficiencies as quickly as it had when driven by US innovation. Meanwhile, China's low production cost will continue to damage its environment and laborers.

    That trade war is the kind of protectionism I expect more of from Congress. If they were really smart they'd give installing locations rebates out of the tarifs, keeping China's profits here along with the maximum output at the locations. But even if not it's not so dumb.

            As for China in the TPP, it's mostly secret, and not complete. Meanwhile "Obama Considering Chinese Participation in Trans-Pacific Partnership".

            "Defied the WTO" is not what I said. I said that the US government protecting our market from Chinese products is not automatically eliminated by the WTO; we have a government despite the WTO.

            Unless everyone here were as fatalistic as you are about foreign trade and our powers to protect ourselves. Then our government wouldn't protect us, though it could. A self-fulfilling prophecy.

                The WTO sets US trade policies 1. because the US agrees to let it and 2. after the US and EU dominate the WTO rules, starting with US laws.

                You are arguing that the WTO rules, and the US government doesn't, in deciding US tariffs on imported Chinese panels. I showed you the US government instituted the tariff, which it's been collecting and the WTO hasn't stopped. Yet according to you "we don't have a government, we have the WTO".

                You are just wrong. And a douche.. But you won't admit it, and you remain baselessly arrogant about your knowledge.

      When Ben Benokraitis bought a solar-powered water heater for his Baltimore County home two years ago, the installation company told him he'd get about $800 a year in payments to help offset the cost.

      That money would come from the sale of three Solar Renewable Energy Credits, or SRECs, his small system would create each year. His solar installer would broker the sales and send him a check.

      But instead of the $1,600 he expected in the past two years, Greenspring Energy passed along $225.25 — payment for a single credit — before laying off its workers and locking the doors to its home office in Timonium at the end of January. Now Benokraitis has little hope of earning a cent for the other five credits.

          collapse was that they were using a third new technology, in terms of materials, that has a higher efficiency than the previous two standard materials.

          But, because they just started they hadn't come down the cost "learning curve" yet, and the Chinese dropped prices of traditional panels, which they dominant, by over 60% because of a capacity glut.

          So the business plans of Solyndra which were based on pre-price war pricing assumptions fell apart.

          It was a "better" technology that U.S. firms owned several patents on. A tragic loss.

        We shall come rechoicing,
        bringing in the Jeeves.

        Whatever, but, I've sometimes sing it as "bringing in the cheese." "Twisting in the wind," "Pissing in the wind."

        When I was young I thought it might be "bringing in the Jeeves" because Jeeves seemed to be a common name for an English buttler or mans man. I figured maybe he'd become senile, and would stand out in the rain, not knowing he should come in.

I believe in protecting every species that we can, but we also have to have some perspective in this incredibly difficult task of becoming a sustainable civilization.

    It takes seven years to permit an offshore windfarm in Federal waters. We do not have one single offshore windfarm in the US generating power. We are sleeping through this pending catastrophe as we burn more and more fossil fuel without much of a let-up.

  •  I have direct experience in the solar industry (3+ / 0-)
    Recommended by:
    DRo, kovie, ferg

    And my local industry effectively died in the last year. As of yesterday, I no longer work in solar. A green job was lost.

    While technological advancements in efficiency are great, they are largely a marketing tool for panel makers. At this time the key issue for panel makers is manufacturing costs, and making expensive, high efficiency panels is a losing proposition except in a small sliver of situations where space is at a premium. And it still is a tough sell because of just how much more it costs to make a more efficient panel. Note that this was Solyndra's problem, they were building complicated panels with unconventional technologies, and worse at a time Chinese makers were dumping on the US market. But I digress, the bottom line is production efficiency is not the problem the industry faces.

    I am in a market where solar is oversaturated. The number of consumer installations is so high that the production is exceeding daytime minimum loads on residential circuits, what that means is there is too much power being made and nowhere for it to go. The utility claims the excess power is potentially hazardous, and that it apparently does not shunt around the grid from circuit to circuit.

    That's the dirty secret of solar -- with current utility technologies, the amount of solar practically installable on a circuit is limited to the amount of power being used during daylight hours. There is no means of storage. Current solutions to overproduction as far as I understand actually waste (ground) excess power. Obviously, the utility cannot credit that production to homeowners without causing a financial problem.

    So practically speaking, solar can only address about half the power need of a given circuit. Given that the biggest power users are likely to be the earliest solar adopters, this means that less than half the homes on a given circuit can have grid-connected solar power.

    Without really practical solutions for storing power, or perhaps more to the point lacking the will or enforced mandate to spend capital on implementing existing storage technologies such as fuel cells, the local utility has basically choked installs to a near-standstill with bureaucracy. This has killed solar installers' revenues and jobs, such as mine, are being lost.

    So articles like this, to people who know about solar, are not compelling. This is not solving the real problem. The real problem is storage. That's where advancements need to be made if solar is to be a bigger part of our energy future.

    •  Why can't utilities buy the excess power (0+ / 0-)

      from consumers to offset what I assume is more expensive power that it makes conventionally? Or is the latter currently cheaper, and if so shouldn't they be given incentives (or taxes) to make the former cheaper?

      Once you include the external costs of most conventional power (which utilities don't pay for), like pollution, global warming, etc., it seems to make sense. Why aren't governments doing this? Because they're in utilities' pockets?

      This all seems so backwards. The technology and acceptance by consumers is advancing, but the economics and law is not. How long can we afford to cave in to the greed of corporations? What are we going to do about it?

And given the potential profit of these technologies, why aren't Elon Musk-type entrepreneurs trying to change this? Utilities preventing it via the legal system and their friends in politics?

            But again, most storage solutions are local, the more local the more common. Residential battery storage is by far the most common. I don't know of any large-scale, remote storage and transmission projects. And again that's partly because I don't think the technology is that highly developed, and partly because utilities don't feel the need to (financially or politically).

            Yes you are right to be concerned about these issues. But one thing's for sure, which was the main point of my first post ... production efficiency is not the area that needs innovation right now, it's storage and transmission of excess power.

              long-term transmission of energy at present and given future projected growth and demand, or can most excess storage be stored locally, with perhaps a more modest long-term transmission and storage capacity built to handle the occasional excesses to avoid wasted energy? With more electric vehicles set to take to the roads and replace gas vehicles, there's going to be a surge in electric demand, most of it locally given that most miles driver are local.

              I guess I'm asking is that, given political and economic realities, isn't a more modest and modular plan for upgrading the nation's power production, storage and transmission network more feasible, if not also sufficient for most of our needs? Do we really need a Manhattan Project-like solution, especially given that none is likely any time soon under present realities?

                  for some middle-tier ventures to store and resupply as needed excess energy, be it from consumers or utilities, at the local level. If these proved lucrative and effective, eventually they'd consolidate and the big players would move in. If utilities don't want to spend the money and consumers can't, this seems like the most likely compromise. Venture capital can do the initial financing.

                  I see someone like Musk getting involved, especially since it could mesh with his plans to build a national network of charging stations, which would be a great use of such a scheme. One person's excess energy could power another persion's EV, to the advantage of both and the middleman.

            adding battery storage adds a huge amount of cost to a residential PV system, both upfront and ongoing. So the vast majority of systems are simply grid-tied with no storage. In every municipality I know of, during the pre-saturation stages, and even post-saturation, the standard assumption is grid-tied with no storage. It would be nice if every PV system stored its own overgeneration, but no government is requiring that. That would hurt adoption tremendously.

            Also, most systems with battery storage do remain grid-connected, for on demand service when and if the batteries ever run out. That can cause technical issues, as the load is turned on and off of the grid.

              I think the future would be something along those lines (though of course RVs don't use as much power as a typical house).

              In the end, reality always wins.

              •  That's the present (0+ / 0-)

                As mentioned this is the most common solution currently, but it is cost-prohibitive to the individual and therefore sees low adoption. The future is solving the financial issue, one major way is larger centralized solutions.

    Sorry, just woke up and coming down with cold. Bad joke day. This sounds great. I've been tinkering with basic electronics lately for my young nephews and was thinking of adding a solar panel as spring approaches. Hopefully these will be commercially available for regular people soon.

    Maybe George Foreman will make a version of his grill that uses these?

  •  ok, here's a question (0+ / 0-)

    my extended family has 3 homes with no ability to put up solar panels.  Either tree shaded, or in one case, the design doesn't allow it (very very steep pitched roof, high and bad orientation)

    so, I was thinking of buying a small lot in a hot cheap area, and putting in enough solar to offset the 3 houses.
    is this possible?

    Imagine the most profound idea ever conceptualized occupying this space. Now expect exactly the opposite. You'll never be disappointed.

  •  China dominates the solar panel industry. (0+ / 0-)

    It confounds me that have to get our panels from China. Solar panels are a great idea, but they are cost-prohibitive for most.

    •  US panels are quite competitive (0+ / 0-)

      Check it out, panel costs are so low that buying US is quite feasible. In fact, my local industry turned almost entirely to non-China panels after the tariffs, and US panels were one of the most competitive options.
