If Tesla Can Run Its Gigafactory On 100% Renewables, Why Can't Others? 444

Lucas123 writes Tesla CEO Elon Musk has said his company's Gigafactory battery plant, the world's largest, will be "self contained" and run on solar, wind and geothermal energy. The obvious problem with renewable sources is that they're intermittent at any given location, but on a larger scale they're quite predictable and reliable, according to Tom Lombardo, a professor of engineering and technology. Lombardo points out that Tesla isn't necessarily going off-grid, but using a strategy of "net metering" where the factory will produce more renewable energy than it needs, and receive credits in return from its utility when renewables aren't available. So why can't other manufacturing facilities do the same? Is what Tesla is doing not necessarily transferable to other industries? Sam Jaffe, principal research analyst with Navigant Research, believes Tesla's choice of locations — Reno — and its product is optimal for using renewable and not something that can be reproduced by every industry.

      I guess they used up all their political will on solar subsidies for one of the cloudiest places on the planet, and they had none left to stand up to the anti-nuke lobby. Which is why Germany is now burning record amounts of lignite (brown coal), one of the dirtiest fuels.

            He focused on energy sources, and his point that the increase in usage of brown coal is neglegtible, is correct.

            You focus on TWh production of elictricity, where you clearly see there is a noticeable increase in terra watt hours of electricity produced ... however no one can deduce how much more brown coal was used for that.

            In fact the amount is indeed neglible, because the "more terrawatts" come from the new more efficient coal plants, that replaced older less efficient ones ... so bottom line the "record usage" of brown coal is still nearly 20% below the 1990 level (in primary energy) and roughly 10% below 1990 level in electric power production.

              While it is true that some efficiency offsets might be made, your numbers simply do not add up to the graph Dunkelfalke linked. It lists lignite at 3201 TJ in 1990 and 1645 TJ in 2012. That is not "[usage] of brown coal is still nearly 20% below the 1990 level (in primary energy)", that is a 50% reduction in primary energy. All of that also happened before the year 2000 - since then, pretty much no reduction in lignite use has occurred. If powerplant efficiency were indeed rising while electrical generation remained mostly flat during the 2000-2011 period, that would imply that a rising proportion of that input lignite energy (which flatlined during that time period too) is being used for heating and other uses. However that doesn't appear to be the case either (coal use outside of electricity is falling rapidly) - this leads me to believe that there hasn't been such a dramatic increase in efficiency as to be able to confidently say that the recent increase in generation is due to an increase in powerplant efficiency. Also, how can you claim use in electrical generation is 10% below 1990, when even you said yourself just a few moments before that "no one can deduce how much more brown coal was used for that". I'd really appreciate if you could cite your sources, that would allow us to clear up the situation. If you have access to figures on lignite consumption by coal fired power plants, that would be great. Otherwise, the only reliable thing we can say is that electrical generation from lignite is at an all time high since 1990.

    The issue can be a complex one, but I think it boils down fairly easily:
    1. Most companies can go completely to renewable power, excepting some where they need the byproducts for other uses. Concrete manufacturing, refining iron and making steel, etc... However, this doesn't mean that it's economic to do so.
    2. There is however a limit - if the manufacturer uses more energy than their roof/property collects, they obviously can't go 100% renewable without obtaining more property.
    3. I figure that it's probably easier to go 100% renewable if you plan to do so before even breaking ground on the factory. Such as selecting a location with nearly ideal solar patterns.
    4. Net metering only works so long as there are other customers looking to buy the power when it's being produced, and generators producing when it isn't. If 'everybody' tries to do it, the system would break down.
    5. To go along with this, even if they can't net meter, they're a battery factory. They can create a lot of backup storage even if they only drain/refill all their produced batteries once as a 'test', cleverly arranged to provide back up power. Or produce some batteries at cost, use degraded but still functional batteries returned under warranty/core charge, etc...

While it's entirely possibly for a company to generate its own power, grow the food its employees will eat, make its own tools, etc. that all adds unnecessary complexity and gets in the way of specialization. Instead, do the thing you're good at and buy the rest. In the case of power, I could see more and more companies adding solar panels, since so much of their cost is installation. But for now going full renewable is only for marketing purposes.

      I would add (6) Many states have regulations making it impossible to do what Musk is doing [latimes.com]. I live in Republican-Controlled Virginia, where I can't buy solar panels from Musk's SolaryCity [solarcity.com], which has a location 20 minutes away from me in Washington DC and more locations in Maryland, because my state has pretty much given Dominion Power a monopoly [energy.gov] on supplying electricity here, giving them exclusive rights to net-metering--which they have made cost-prohibitive to implement, and the company has actually successfully sued organizations that install solar panels.

    The fiction of net metering is that you will not be paid the same amount for the electricity you generate as for the electricity you consume.

    On of the purposes of "Smart Meters" is to permit differential pricing on electricity produced vs. consumed; it's not just to provide a temporal demand market. There are already tariffs in place in California where PG&E only has to buy as much electricity as you consume for a net 0 energy usage, rather than being required to purchase everything you generate over what you consume.

    The idea of a large grid only works if someone pays to maintain that grid, and that pricing comes in as a differential.

    Everyone can't do what Tesla is doing because not everyone is going to have the storage capacity to make it economical; Tesla can just rota the batteries it manufactures in service to the manufacturing plant itself, as part of "burn in testing", so that it'll get local off-grid storage as a side effect of the manufacturing process itself.

    I suppose that "every rechargeable battery manufacturer can do what Tesla does" would be a fair statement, but that's a tiny subset of "everyone"

    The obvious problem with renewable sources is that they're intermittent at any given location

    Yeah. How are they going to store intermittent power for when they need it later? At a battery factory?

    This is a tough problem.

    You cannot base any real analysis on figures take by looking at an artists rendering of the site.

    The article says that they will have 85 windmills because there are 85 windmills in the picture. This is garbage. It is an artists rendering!

    If you want to have a serious discussion, you have to wait until there is some actual real info to discuss.

    Note that net metering is not running your plant completely off renewables. It's running it off renewables some of the time.

    So why can't other manufacturing facilities do the same?

    It's generally called "co-generation", and although that applies to energy generated by a wide variety of means many are renewable. Burning methane from sewerage treatment plants to run generators is one with quite a few decades of history, another is burning plant waste such as "bagasse" from sugar cane.

    • In addition it kinda depends on what it is that you are doing. If we take this facility what is it actually doing? Is it assembly, which takes a relatively small amount of energy, or is it full fabrication, which obviously uses a lot more.

      I have no idea what is in these batteries but lets say they look like lead acid batteries internally for the sake of this. Are they taking in lumps of lead, heating them, moulding them and then placing them into plastic containers which were shaped and formed in a diffe

        Let's not, that's getting as irrelevant to comparing manufacture of welding rods to sex toys.

  • How is the product relevant? Isn't it more about location? If you build a gigantic factory building, you can put all kinds of things on the roof. If you built in a location that has sun, wind and geothermal capabilities, how would your product influence whether you could go renewable?

    Isn't it still about whether you can get your investment back and in what time-frame?

    When I go to a high point in this city and look down, I see countless flat roofs that could easily host solar panels. Even with all the fog this city gets, that would make a significant impact on our use of non-renewable energy. But it is not to be. Homeowners tend not to like the upfront expense, they tend not to know about SolarCity, [solarcity.com] and a bunch of the homes are rented. Absent some regulation, they aren't going to install renewable energy.

    I think the neatest time to add renewable energy to a building is during construction. Absent that regulation, unless the owner makes it a priority, then the architects are not going to add it to the plan. For example, my work place recently commissioned and moved into a new building. It has an unobstructed, south-facing, 2-story-high, 10-foot-wide window that we have to cover up on the inside to maintain the climate. My immediate thought was: Solar energy. But I had no authority; the people in charge just put a poorly designed curtain on it. It just doesn't occur to them that we could put renewables in this building.

    Actually, in the current political climate, I think renewable energy gets negative publicity from these deployments. Conservatives under the thrall of Koch money see renewables as an admission of AGW, and reject it. No! That reason is stupid! And regardless of AGW, renewables will help us survive the depletion of the oil reserves! The Koch-funded people claim that there is no depletion. I live in a state of extreme pessimism.

    Tesla is doing this

    Uhm. They haven't even broken ground yet. So no, they're NOT.

    Until the site is up and 100% operational, this is all smoke being blown out someone's ass.

    Why don't others do this?

    Because this sort of solution isn't suitable everywhere.

    Reno sees about 250 sunny or partly sunny days a year, with roughly 60% of those being totally sunny.

    A place like Chicago sees 189 sunny or partly sunny days a year with roughly 40% of those being totally sunny.

    Places like Reno don't have to deal with long stretches of extreme low temperatures and snow measured in feet.

    Also, there's the land use to consider. Farmland is a LOT more valuable for what it can produce than a big stretch of desert land. So converting it to a wind/solar farm from food production is idiotic.

    There's also issues of space availability. If you have a factory in someplace like Los Angeles, you simply aren't going to have the land area to build a totally renewable setup.

    On top of this, what other environmental impacts does building in this manner, on a wide-scale basis (not just one factory, but dozens/hundreds/thousands of businesses and their facilities) have?

    There's also the issue that the local utility needs to be set up to accept power back into the system.

    And finally, if everyone's doing this, how do you maintain a stable power production industry? And how does the industry finance maintenance, expansion and construction of new facilities to replace old/obsoleted facilities that have met/exceeded their productive lifetimes?

      And here in Grand Rapids Michigan we have several places that do it. The Van Andel Institute for example is covered in solar on their roofs and their solar program is very successful even through last winter when we saw more snow than Minnesota saw.

      How about instead of wild speculation you actually look up the places that ACTUALLY have done it and have been running that way for years successfully?

      Even Michigan Tech way the hell up against Lake Superior has a successful Solar power generation system in a place where they get on average 6 feet of snow falling per winter storm and over 30 feet of snow fall for the winter.

    One of our production facilities installed two large windmills that supply roughly 10-15% of the power the plant uses. You would think this would lower the cost for purchased electricity, but it didn't.

    The electric company raised the rates for our plant because the usage dropped enough that they entered a lower usage bracket which has a higher cost per KW/h. We actually pay MORE each month in electricity costs even though the plant purchases 10-15% less electricity..

    Obviously they are negotiating the contract terms now (it may be done) but this is just one example of how the utilities have everyone by the balls. They are going to get their money, one way or another.

    I'm sure for Tesla, it will be easier since they are starting from the beginning instead of doing a retrofit. However I hear similar stories from residential users. Most times people want to make the choice to use returnables but outside factors make it monetarily difficult to pursue.
