How energy storage will kill fossil fuel.

Utility scale batteries have been dismissed by some as no more than a useful bolt-on to our existing electricity grids to help with a little bit of demand stabilisation here and there. But dramatic cost reductions, improved efficiencies, and a plethora of new innovations in how to store energy that can be delivered into the grid over long durations have all contributed towards a rapidly changing market that look set to revolutionise how we structure our global energy systems towards a fossil fuel-free future.

As control room operator at FP&L for over 20 years I have seen the effects of low frequency on the grid. What typically happens in hot weather is as frequency gets lower due to not enough generation capacity dispatch load control will start shedding load during brown outs in order to keep frequency up... If there is enough battery capacity to supply enough load during this time it can eliminate brown outs. So green energy is a good option to prevent brown outs and load shedding..

[@flagmichael]

Florida (In particular Florida Power and Light) is recognized in the US electric industry as one of the most robust areas in terms of energy management and disaster recovery. Here in Arizona we have hurricanes occasionally wander through the southwest corner, which does damage you would laugh at. "Aww - did it undermine a 500KV tower? Poor babies?" I completely agree with storage being magic for short-term stability. Here in the West we don't have enough Remedial Action Schemes, although California does pretty well. In Arizona the plan is to rely on line protection and manual switching.

[@acmefixer1]

@Patrick McNulty With a conventional generator the load is coupled electromechanically to the generator. But with the electronic inverter the frequency determining oscillator is independent of the load. If the load varies the frequency stays the same, and if the frequency is generated by a crystal oscillator, the frequency can be very accurate. So the only thing that will vary is the voltage. It used to be that the frequency was critical to many devices, but nowadays most devices don't depend on it.

[@captspiff6922]

@@acmefixer1 So what you are describing is an inverter which is not grid connected. For any grid connected inverter, it becomes a frequency follower, with a very small bias or "slope" toward standard. The conventional generator, as you mentioned is coupled, however it too has a "droop characteristic" which biases it toward standard (60hz in North America), which gives the grid stability.

I suggest you do a segment on liquid metal batteries provided by Ambri. Inexpensive, efficient and reliable with very low degradation, they offer an exceptional solution for grids and likely for businesses and homes.

[@vincentrobinette1507]

This is exactly right. electrical energy storage is the ONLY thing keeping renewable energy from being the dominant source of electrical power. My idea, is similar to your idea of "behind the meter storage". Having a substantial battery at home makes the most sense right now, because the LCOE of the battery only has to compete with RETAIL rates, rather than WHOLESALE rates that it would have to compete with in front of the meter. If homes and small businesses could do a thing called "peak shaving", there would never be a need for peaker plants in times of peak demand. Peak shaving works by battery chargers set to a voltage threshold, where if the voltage from the grid sags below a certain level, the charger turns off, unloading the grid. When the voltage rises,(hopefully due to the wind turning turbines)then, the charger(s) come back on, charging the battery bank. Under high demand, your loads just run on your own battery. Once you have a DC storage system, that system can be supplied by rooftop solar, wind, micro-hydro, or any other source.(in worst cases, a backup generator) With four sources of power, you have no problem maintaining 24/7 power.(solar, your battery, the grid, or backup generator) you could even have a 5th source, if you have a wind turbine. with grid electricity getting more expensive, and off grid solar equipment becoming less, there will be a crossing point, where you could save money putting in your own off-grid photovoltaic system with battery. In the areas where local ordinances do not allow disconnecting from the grid, the peak shaving system I described above is a good idea, besides, the grid is a good backup, in case something goes wrong.(A peak shaving system is sometimes referred to as a "grid autonomous" system) A system like that could easily be adapted to work with the Zellweger ripple system, in case the voltage rise is due to a peaker plant, and not excess power from a windy day.

[@kiae-nirodiaries1279]

This is a complex subject, well researched as ever and put into context. Recently retired, my last job was in the IoT space and Smart Grids were an application I studied. Storage changes everything and with batteries getting cheaper the opportunities for balancing the demand/supply equation and providing frequency response services to accommodate more renewables are increasing. The challenge is one of management which needs a lot of real-time data collection. Blockchain looks to be the best solution using connectivity technologies such as cellular, LPWA and MESH networks. We come from a world of a few power sources and many power loads, the new world is where millions of loads are also sources, e.g. electric vehicle batteries supporting V2G on the low voltage part of the grid. This is a potential nightmare from a management perspective but again IoT technology should be up to it. As we used to say, giga bytes are just as important as giga watts.

[@teekay1785]

yes but remember electric vehicles though providing a large load could also be a huge source and once the system has adapted to the demand of electric vehicles they could be a huge source to help balance demand like electric hot water tank remote utility controls have been. In other words shut the charge off to the vehicles and maybe even draw from their batteries down to a particular capacity.

[@kiae-nirodiaries1279]

@@teekay1785 Yep, that’s about it. Just remember that every time power goes back and forth there’s a transaction to be done which is why I repeat, the Mega bytes are as important as the Mega Watts.

An excellent and well researched presentation as usual. The good news is that the market is moving more quickly than the regulators, especially in some of those "developed" countries that love to dig their coal and burn it. I'm hoping that domestic batteries will be included in the upcoming UK efficiency grant scheme, that will be a game changer for me, allowing me to both store my own solar electricity, and buy grid electricity at lower rates during the two blocks of three hours a day that are really cheap in the UK. Leading on from this, that will bring the running costs of moving from gas central heating to air source heat pump central heating PRICE EQUIVALENT in the UK, which is where the carbon game really starts to change.

[@siggyincr7447]

Decentralized energy storage is where this is headed for a lot of good reasons. First and arguably most importantly, as it becomes more widespread it will make economic sense due to increased engineering expertise and the cost savings that come with mass production of the components needed. Secondly, storing energy closer to where it's being used reduces transmission losses during peak usage times, when they are most detrimental. And beyond the stabilizing effects on the electrical grid mentioned in this video, it will go a long way towards making renewables feasible for providing the bulk of our energy.

[@Simon_Jakle__almost_real_name]

I say a (partial) solution are big mechanical batteries and gravi-tricity (lasting long enough). We make hell out of nature generating electricity, so we can't trasure the value of it handling the current as a business, also because we do not know what an electron is made of. Blockchain itself will still be a too hungry thing ("mis-trusting" people, that don't try to learn about electric current), i can't think of blockchain having gotten less complicated

[@TheSpecio]

Run your house with solar power and you will need lead batteries worth about 200,000 Euros to provide sufficient energy storage to become independent from the grid for up to 2 weeks (Times without sufficient usable sunshine can last much longer!). These batteries have a lifespan of 10 years after which you need a new set. And lead batteries are and will be by far the cheapest batteries of all.

[@marekstepanek6501]

Really impressing your film. The illustration of it let me think, that there is a big lobby behind your channel. Love your British accent. Me as a German (please forgive me my English!) am sceptical against so called renewable energy. Because we already pay for it very high. We have the highest energy prices in Europe, probably in the world. We live constantly close to a blackout. If we have had no neighbours with coal or nuclear plants, our system would crash very often. 2018 we have had two critical moments in our grid. In your film you are showing a beautiful landscape at the beach "decorated" with many windmills. This was a symbolic picture: human greediness and ideology destroying nature! My point is not: I am against electrical storage. No! Not at all! This is even the crucial problem of renewables. I am for obligatory solar panels on flat roofs in industrial areas. But I am against Solar Parks on fertile soil or in woods, against cornfields for our electrical comfort. Simply because of the efficiency of renewables, the so called EROI (Energy Return on Investment), which is too low. For that reason they need a big area to compensate. Photovoltaic has an EROI of 1.6, Biomass 3.5, Wind 3.9, Gas 28, Coal 30, Water 35. In comparison to it the old veteran of Pressurized Water Reactor has an EROI of 75! Which is not too bad. The windmills are meanwhile as high as the television tower in Stuttgart. The concrete weights 7000 Tonnes. The socle of 3500 Tonnes is left for ever in the soil. The wings are impossible to recycle - they still look for an solution for this problem. And many birds and insects are victim of this sort of environmental protection. But if you compare the renewables with the new concepts of nuclear power plants of fourth generation, you will understand, that the increasing demand of energy needs a new investment of nuclear plants of the fourth generation: MSR, LFTR or DFR: They have an EROI starting from 1000 up to 2000, some people of the DFR-Team claim even an EROI of 4000! They are safe ("Walk away Security"), they are modular, fit into a container and the best of all: they burn up the nuclear waste of our good old Pressurized Water Nuclear Plants. Ah, I forgot: they produce energy very very cheap. Ah, one point more: because they run with Thorium, they could produce for the next 1000 years, without leaving behind tonnes of garbage with a long decay as the old nuclear plants. Because of the high process heat from 1000 Grade Celsius, you could add to such a plant innovative techniques like: PowerToGas with Hydrogen Production, Synthetic Fuel, LOHC, NanoFlowcell, Seawater Desalination, Long-Distance Heating. These added spin-offs could solve many problems around the globe. And the power plants themselves could help, to give back nature to nature, because these plants don't need space. Specially in Germany the Green politics have destroyed big terrains of woods with the windmills, fertile land with solar panels. And they call this environmental protection, and declare it as nature protection, which is not the same! But we do not need this sort of environmental protection. We need a new wilderness for biodiversity. In Europe there are no virgin forests anymore (ok, in Poland, the Białowieża National Parc). Just have a think!

In Italy we are masochist and prefer to kick all the brains out in change of some desperates from Africa . It happened with Enrico Fermi too, who built atomic bomb for Usa instead of us . We would have won the ww2 with that and probably nuclear power would have been more important then oil now .

[@acmefixer1]

The researchers have experimented with agrivoltaics, where the solar panels are located in farms. The plants grow bigger leaves to compensate for the shade. There are no conflicts with putting wind turbines among the fields of farms. I have nothing against nuclear power, but it's very unfair for anyone to say that renewables are harming the Earth! That's what this German is saying. The harm is being caused by a fossil-fueled world and it's absolutely necessary to get rid of all CO2 causing sources. One point people fail to talk about is that thermal power plants -- nuclear too -- require a huge amount of water to keep the plant cool. This is a major problem for locating these plants, so they are located close to water. The German complained about wind turbines; there are more huge high voltage towers with thermal power plants. Wake up world! Thorium or any nuclear material is not renewable. The problems in Germany are not problems for all other countries.

[@mikemccarthy1638]

Marek Stepanek - That is a fine exposition, my friend, of the benefits of nuclear power, especially in densely-populated Europe. “Desperation is the Mother of Re-invention” should be Germany’s motto if it ever wakes up to its energy mistake, after Fukushima, in closing its nuclear power plants that still have years left of CO2-free power production: If they’re not restarted, the CO2 produced in their construction added to the climate crisis for no benefit. Even worse, the country burns brown coal to replace the lost power. How the greens can be happy with this, much the same as they do here in the US, says a lot about their unreasoning fear of nuclear power. The coal, oil & gas interests spent large sums to deny the climate crisis & postpone action to address it for decades. Natural gas was once suggested as “the bridge fuel” to a green economy, but the delays have made that impossible if we’re to avoid the worst consequences of global heating. The bridge fuel now is nuclear, at least until we’ve reached the point of negative growth in CO2 concentrations. If the greens had been able to stop the fossil fuel industry from spreading their climate denial propaganda, they could have bought the time needed to avoid temporary resort to nuclear. For understandable reasons, they failed. Now it’s time to face reality: For the next 50 years or so, we either use nuclear or sustain dramatic reductions in living standards in order to avoid industrial collapse and eventual extinction. A little more perspective to close - Back in the ‘70s & ‘80s, at least until climate scientist James Hansen testified to the US Congress in 1988 of the seriousness of humanity’s situation, the term “Global Warming” might have been good for giving us a gentle wake-up call about the developing science. But now we need words that accurately describe our terrestrial reality - “The Climate Crisis, Ocean Acidification and Global Heating” (Ocean Acidification comes first, because few people even know it’s happening, never mind that it’s caused by fossil fuel pollution.)

[@mikemccarthy1638]

@acme fixer - The greens around the world have spread unreasoning fear of nuclear power for decades while tens of millions suffered unhealthy lives & premature deaths from fossil fuel pollution, esp. from coal-caused CO2 & SO2 pollution, fine coal particulates, coal dust & mercury pollution. As for Germany, as was explained, it shares its problems with the rest of densely-populated Europe, w/ its interconnected electricity grid. Assume the rest of Europe had followed Germany after Fukushima in shutting down nuclear in favor of burning stuff like brown coal (while at the same time allowing the expansion of diesel vehicles as they did): Europe would have experienced depression-like conditions & a health crisis like China’s. Their gov’ts, industry & homeowners would not have the funds to expand wind & solar. The Euro-zone would now resemble something more like Central & Eastern Europe around the time of the fall of the Soviet Union. Would the EU have survived; how would terrorism have played out in the new slums of Europe; how much more aggressively would the Russians have behaved; how much more would reactionary conservatism have grown beyond say, Hungary & Turkey (you can start with France...); what would have happened to the Syrian refugees, most blocked from entering Europe; and how would that weakened EU/NATO, with a stronger Russia, have played out in Trump’s America? Now go up one level higher: Many Muslims in MENA, from Morocco to Iran, have respected Europe’s social democratic traditions of medical care and other social & educational services for all that have prevented the levels of poverty found in the US & elsewhere: how might their changed attitudes have affected things today?)

Great video! One (very!) minor nit: transformers are not used to drop voltage to 120VAC in the US for household usage. It comes in as 240 two-phase and is split to 120 (no transformer needed) at the distribution box in the building. Things like electric stoves, heat pumps, and car chargers are typically wired for 240. It's split to 120 to make it safer. If you look at the old 'tube and insulator' residential wiring used when this first became standard, it makes a lot of sense. But yes, AC is the key to electric distribution.

Ever Sunday, I look forward to watching your blog, and I have a thought that is rattling around in my brain, and want to present it to you, even though it is a tangent topic to today's show. It is geothermal, to be used for commercial and residential heating and cooling, powered by green energy, using heat pumps. Ground based systems have a sweet spot that is driven by latitude. This Goldilocks latitude is not at the Equator (ground too hot), nor the Arctic (ground too cold), but between these, where it's just right. And there, in this good zone, the expensive part is to get this desired temperature content. Drilling can almost always be done here, almost like drilling for oil, except you're guaranteed to hit your prize... local appropriate temperature circulated water. If there were millions of holes drilled and tens of thousands of drilling rigs, especially if these rig operations were funded by the state, then costs would plummet. In addition, the inside the building conditioning systems costs would be slashed as well, as you need only the heat pump. You don't need a furnace. And costs in the heat mode and the cooling mode are slashed by roughly seventy to eighty percent. Your mileage may vary. This is a winwinwin. And the carbon exhaust cost saving are similarly accumulated. Another win. In cities, the system could be provided by the municipalities, as a utility. City living costs would plummet, and it's environment would be in it's own sweet spot. In effect, you are using the Earth as a battery, swapping summer heat and winter cooling. Swapping it for six months later.

On airconditioning: If you have water supplies, a "desiccent cycle" solar power air conditioner is the way to go. It goes like this: 1) The sun is used to dry the water out of some desiccent. 2) This desiccent is used to dry the water out of a fair amount of air but this makes the air hotter and dry. 3) The dry air is cooled to outdoors temperature. 4) The air path is split into two and one has quite a lot of water added. 5) This much cooler but too wet air is used to cool the other path. 6) The now cooler dry air has some water added and that goes into the living space. There is a method that can do even better with doing a 2 of the 2 way splits but this uses about double the water.

Energy storage can not control the frequency or phase of grid but can control the voltage supplied to the grid. Also energy storage introduces larger in efficiencies into the grid which will require more generating capacity for the overall grid. Energy storage will allow for cleaner renewables to account for a larger percentage of the generating capacity of the grid and will eliminate the even more inefficient and a major polluter of the fossile fueled peaking stations within the the grid. As of such they probably won't replace conventional power stations but will reduce the amount of conventional stations and above all the very wasteful & major polluters of conventional power stations on the grid. Once someone comes up with a way to maintain a reliable grid phase then a 100% renewable grid will be feasible. Either way the main need in the grid is power storage. We should be perusing power storage more than renewables. You can't put the cart ahead of the horse.

There is a certain danger in saying "once we have storage solved, then we can go alternative", much like saying we need to get to zero, it presents an impossible goal so that the status quo can continue floundering along.

Seasonal storage is a huge obstacle to renewable (electric) systems. A home in Canada's far north can require stored energy for 4 or 5 months a year and given the very high demand during the winter, would require approximately $4 million in Tesla Powerwalls to assure safe levels of heating. However, geothermal storage of low grade (heat) energy offers storage at under 1% of the cost of electrical energy storage. See "The Renewable Energy Transition, Realities for Canada and the World" for the concept and some hard numbers and examples. Electricity is a high grade energy but we have to also learn to use low grade energy (heat) if we are going to make renewables work.

Unfortunately, the conversion efficiency for H2 compared to Li-Ion battery storage and many other currently interesting forms of energy storage is not that great. The current conversion efficiencies are 65-70% for electricity to H2 and 50-60% for H2 to electricity. Charging and discharging Li-Ion for ordinary batteries are both in the 90% range. You lose more than half of your energy from the get go if you use H2. It's only when you want to store the energy for a very long time (years or longer), in a small container or may want to transport it over long distances (between continents and thus preventing significant transportation loss through HV lines) that H2 may make sense. The small container size may have been an advantage for vehicles a couple of decades ago when Li-Ion batteries weren't yet as well developed as they are now... but with the current progress and the next stage of EV car (>500 mile range and cheap compact cars) on the horizon, I don't think H2 makes sense anymore.

[@grindupBaker]

To clarify at 3:50 "power plants could be sped up or eased down somewhat" this cannot mean that the generator can be sped up or eased down somewhat because the 3-phase generator must turn at 1200 rpm to generate the 60 Hz voltage sine wave so its speed must be held invariant. I don't know how they boost or throttle back the power to match demand but I'll tell you the sort of thing that could do it (so they probably do something else but mine is workable too). It's precision governor like car cruise control or lawn motor governor, but likely better. It's like this. The basis is that the more current is being drawn from an electrical generator the more "opposing torque" is being applied to the generator shaft, trying to bring it to a stop. This is literally what happens. So it's required to have it turn at 1200 rpm but as demand surges, drawing more current, that causes an effect (you know, electromagnetism, the magnetic field in the generator) that's exactly like you was Arnold Schwartzenegger and you grabbed the shaft and was trying to pull it stopped. So it drops to 1199 rpm so frequency drops to 59.95 Hz (see video for actual UK frequency recordings). It's probably direct computer & solid-state feedback now (like elevator controls, my discipline for 20 years before retirement) so the tacho pulse generator "instantly" notes speed drop to 1199 rpm and the adjustable hydro dam tube diverter (I'm completely making this up) or fission/coal/oil steam diverter (I'm still making this up) diverts an appropriate (computer calculated) extra amount of water or steam from some waste exit tube into the driving tube which shoves harder on the turbine blades than before and the turbine blades rotate faster and 1200 rpm (60.000 Hz) is again achieved. So it's ----> ----> -----> -----> ----- Another way than "adjustable diverters" that I just made up would be some type of variable clutch arrangement that can modify the force applied to the turbine blades. I think the "adjustable diverters" sounds better though. The engineers will have thought of a way of varying force (I suppose it's actually "power" in the physical sense) to the turbine blades to maintain 1200 rpm than my 2 quick suggestions but I'm not going to search for it. This is a classic "negative feedback" so you see the fun analogy to global warming. That's a "closed loop" precision negative feedback. Before solid-state electronics & computers it was "open loop negative feedback" (I'm on elevators now) and a top aging mechanic called "adjuster" would spend many hours adjusting taps on big resistors and maybe cutting some capacitance in or out and adjusting the length of a resistance metal strip shunted across the field of a generator, all to hold elevator speed the same with a load of 1 or 20 people in it. It was called "flat compounding" and it was an art/science skill. Note the analogy elevator speed constant to 1200 rpm (60.000 Hz) constant. Nothing was monitoring speed because no solid-state electronics or computers so it was always adjusted "under-compounded" because heat alters resistance and attempting "flat compounding" could lead to "over compounding" which is a safety hazard that I'll explain. But I just realized there's 2 things similar but different. ---------- Negative feedback "over compounding" would result in an elevator carrying heavy load getting higher speed than an empty elevator because the circuit compensation was set too high. This could cause emergency braking at full speed and people stumble or at least claim they get back aches now. ---------- The more interesting is "negative feedback overshoot" which is exactly the same as poor car driver who takes a curve too wide and when it's crossing the centre line adjusts hard and has it veering back towards the ditch and adjusts hard the other way and now has it headed straight across the road into the oncoming traffic. You always calculate the correction needed and then make ~50% of that correction and wait to see how that works out before doing a fine-tuning correction, or many. So, user demand increases, current draw increases, force stopping the turbine increases, turbine slows to 1199 rpm and you compute the adjustment to driving force (steam, water or hot high-pressure air) to get 1200 rpm, then make only 50% of the adjustment and briefly after check again (in reality it must be continuously measuring) else you might adjust speed like this 1199 --> 1201.2 --> 1188.7 --> 1201.6....... constantly over-correcting and getting ever further from the required 60 Hz (or 50 Hz rotation rate). For an elevator it could cause over-speed and emergency braking.

[@alex29443]

the storage of energy for long periods is the problem. There are a lot of ways to store and release relatively small amounts of energy and they can be profitable by buying low and selling high. The problem is when you have a cold, windless period in winter. You need terawatt-hours of storage. This is seriously non-trivial. for the UK, (assuming cars, trucks and domestic heating are electric) in a cold 20 days in winter you need the ability to store energy equivalent to lifting ~30 cubic kilometers of water through a kilometer... you cannot store this energy in batteries, as it is too expensive by far, you cannot store it in pumped-hydro because there are not enough good locations. Thermal energy storage and kinetic storage decays with long periods of storage. You could electrolyse water and store hydrogen and oxygen to burn. But this is still quite inefficient at the moment, as Hydrogen has a habit of escaping wherever you put it and is quite expensive and difficult to maintain in liquid form. (side thought, you could put the hydrogen into the existing gas network with a little tweaking, could be a good way to do it). If you are serious about zero carbon you pretty much have to accept that nuclear will be a large part of your energy balance (unless you live in a place with great geothermal potential), and that there will be a lot of dams and other large-scale infrastructure that will need to be built, which will inevitably push up the price substantially. Either that or accept black-outs in winter where loads of old people die.

Grid operators, not so much. operators of fossil fueled power plants better figure out a "plan B". The grid operators merely transfer power from the sources to the loads. the sources will be different, the loads won't change at all. The power purchase agreements go to the generators that can offer power at the lowest cost. LET THE CONTEST BEGIN!! (Just let free enterprise run her course) I do believe, however, the grid operators should invest in electrical energy storage as part of their own infrastructure. That way, they can accept the cheap renewable power anytime it's available, and sell it, whenever there is a demand. They're the ones, who could profit most from large scale electrical energy storage.

Notice that the speaker never discusses costs. This is the hallmark of green vs. carbon energy debates since the costs of most of the ambitious green proposals makes their implementation economically absurd. Take for instance, the recent customer power outage in California. This was due directly to the decommissioning recently of peaker gas power plants that served 6 million customers. When A/C demand during the heat wave became too great a power draw for the grid there were no batteries or neighboring states with power to spare and 300,000 customers had to be blacked out for an hour. The estimated cost to buy the 12 Gwatts of batteries to remedy this problem is $91 billion for four hours of back-up. Then, to keep the batteries charged another 12 Gwatts of supplementary solar and wind will have to be built to be sure the batteries are charged and ready when the main solar and wind portfolios are too busy to charge, at a cost of another $20 billion. So essentially you need twice as much solar and wind in California to keep and maintain a battery backup of four hours standby. $91 + $20 billion = $111 billion which amortized over a payback period of 10 years is $100/10 = $10 billion per year which must be added to the $41.6 billion that Californians already pay for electricity per year. This mind you is only for four hours backup. Eight hours or 24 hours or God forbid a whole week makes it all infeasible.

[@fjalics]

You are making ridiculous assumptions to "prove" your point. Nobody is going to have a bunch of equipment like that sitting around to use it once per year. Your whole perspective is wrong. We had a problem so it's impossible. Nonsense. As the percentage of renewables increases, of course we have to adjust. You should look at his video on liquid air batteries. Sounds like a great solution for a one off situation. I think the most efficient way to do it is to expose everyone to the actual real time price of electricity(time of use pricing), using meters that can measure not only how much you use, but when. One obvious thing, is not charge EVs during those peak hours, but do charge them when electricity is plentiful. Google Ice Bear. It is an air conditioner that stores cold, in the form of ice. I have 2 Carrier 42 SEER mini splits. My whole house AC is 13 SEER. The minute you give people a financial reason to help with these peak hours, they will. Sure there may be a coule of bumps in the road, just like there were with fossil fuels. We'll figure it out.
