I will tell you the fake and true news about energy and environment over. the past and next 100 years Fake news is that renewable forms of energy. are green Hydro biomass solar and wind are renewable but not green at. scales that power billions of people True news is that mobility the great gift. of petroleum is more precious than prices usually tell Reducing mobility. cruelly limits access to education mates and jobs Humans want low cost. speed with minimal fallout Petroleum has excelled for a century in this. role The hard news is that it will likely be surpassed soon and you must. urgently think further than petroleum though it abounds. The heart of the story is energy density exemplified by the 400. horsepower of a 1960s muscle car The long term driver of the evolution of. the energy system is rising spatial density at the level of the end user For. simplicity think of watts per square meter As humans concentrate in ever. larger taller cities watts per square meter rise and finally only electricity. and energy gases basically methane or natural gas and hydrogen meet the. specs for 21st century cities Think of the voluminous Houston convention. center and the high rise hotels in symbiosis with it almost totally electrified. The kitchen may still use natural gas, Finally to supply electricity and gases to the end user fuels that benefit. from economies of scale will win on the supply side Cords of wood and. heaps of coal lost out to denser sources of supply that flow through grids. that go from aortic to capillary, Old fashioned magnets lost too Metallurgical vitamins called rare. earths allowed magnets of equal force to shrink in size by more than an. order of magnitude and thus proliferate Density and miniaturization. bestow power and grow markets as the ubiquity of computers shows us. Like wood and coal petroleum has also lost markets for most energy. uses Oil has retreated to motor vehicles where tanks rather than grids have. made and still make sense,Electricity and natural gas. The well known global challenge for electric generation is. decarbonization The power industry s desulfurization already shows. the way Consider the trajectory of U S sulfur emissions peaking. about 1970 America achieved desulfurization through a blend of. means Geologists found and produced less sulfurous coal and oil. Engineers made the same coal or oil emit less sulfur Firms added. sulfur free gas nuclear and hydro to the generation mix Now. sulfur is essentially a solved problem Along the way legislation and. regulation sometimes led and sometimes followed America found. strategy to conform to our fate that is the preset trajectory. For carbon dioxide data suggest that 2007 or so flagged the year of peak. American emissions Figure 1 I am amused by the huffing and puffing of. politicians and nongovernmental organizations many of which I support. America is right on schedule for decarbonization regardless of Clean Power. Plans and elaborate Paris costumes whose main benefit may be to make. sinners feel virtuous The U S economy decoupled from carbon during. the 1940s long before congressional hearings about it For deeper reasons. the country shifted to natural,gas and nuclear power and. these together with relentlessly,rising efficiency and changing.
industry composition will carry,us to a low carbon economy in. another 50 years or so,While sulfur is,overwhelmingly bad stuff. to pump into the air carbon,dioxide is a much more complex. story Plants love it and good,evidence suggests that Earth. Figure 1 Carbon emissions seem near their peak If the fall is symmetrical is experiencing a global. about 75 years are needed to return to a very low level of emissions greening associated with.

While some commentators focus on bad weather news in fact recent. years have brought record yields for most crops and food surpluses not. shortages The steady brilliance of farmers lifting corn yields first forced. Americans to eat hamburgers and now our cars to drink ethanol Figure 2. Global agriculture is a good deal larger than needed taking into account. the 30 percent or so of all food that is wasted grain diverted to ethanol. excessively meaty diets and obesity,Now some of you might like. biomass fuels because they are,essentially recycled natural gas. called fertilizer and oil called,tractors We pour one unit of.
energy on the land to extract,perhaps 1 2 a sad return and. a vicious use of acreage The,acreage in America for biofuels. equals Iowa or Alabama greater,than the size of all the national. parks in the lower 48 states,The cause of insanity such. as ethanol is not only the Iowa, primary and clever lobbying Figure 2 U S uses of corn Food uses include production of high fructose.

The danger is still in what could happen that perhaps we will abruptly. let loose a lot of weird weather and ice for which our immense investments. in water supply and coastal living are poorly prepared Harmful feedbacks. could amplify bads and a disaster movie results with more sequels than. Fast Furious Finally I know of no objective basis on which to calculate. precisely how risk averse Houston or Texas or America or the world should. be But let s agree for now that if geologists engineers and businessmen can. cheaply sequester some carbon as well as decarbonize let s do it to lessen. worries and perhaps probabilities, Helpful leverage comes from the opportunity to operate mighty methane. power plants with CO2 as the working fluid at very high temperatures. and pressures that also allow CO2 to be separated captured and later. sequestered A 5 GW cluster could fit in the footprint of a power park now. producing one tenth that power And the Houston region shows the way. more precisely the firm Net Power which uses a variation on the cycle. that I and my pals in Austria and Japan first described about 25 years ago. Net Power shows that methane can generate gigawatts compactly while. conveniently providing CO2 that petroleum geologists know how to reinject. into the crust and store,Renewable lies fake news, I mentioned watts per square meter at the outset During my career.
and I accept some responsibility for this decarbonization has become. synonymous with clean or green energy But this is a harmful fallacy. The core of green is not zero or low carbon The core of green is No. New Structures or at least Very Few and Compact Structures ones. that fit into existing footprints or whose footprints can be readily. 1 GISTEMP Team 2017 GISS Surface Temperature Analysis GISTEMP NASA.

summarizes the amount of land that each renewable devours For reference. oil and natural gas produce about 25 to 30 watts per square meter and. nuclear 50 or more As a rule of thumb an oil or gas well equals about. 20 large wind turbines Variance depends on the stage of life of the well. horizontal drilling and other factors, I use watts per square meter as a common denominator and will refrain. from adding facts about dead bats or rivers without salmon For a thriving. nature beside human nature sparing land and sea is green requirement. number one Without habitat life has no chance to adapt or migrate to. warm or cool wet or dry, For meager return windmills industrialize the landscape with concrete. and steel and use an order of magnitude more such material per megawatt. than methane Consider that each windmill is constructed on site from. gargantuan subassemblies transported at great cost over public highways If. small is beautiful wind is ugly, Of course if you like wind you better love transmission The cables turn. the sky into laundry lines for invaders from Jupiter The net result is what. Bill McKibben called the End of Nature over immense acreages Consider an. example from California To replace the kilowatt hours of the 1 5 square mile. 2200 MW Diablo Canyon nuclear power plant would require a 250 square. mile wind farm Figure 3 Or consider examples from the Middle East and.

My own preference is self sinking capsules of waste hot and heavy enough. to sink through the crust reach the mantle and dissolve there Think of the. China Syndrome as a solution rather than a problem. Petroleum and mobility, At the outset I hinted that humans are territorial animals We.

As many films and songs testify modern love,owes a great deal to petroleum geologists Indeed. when scholars in future centuries ponder the 20th the. car may well symbolize our civilization As the 21st. century dawned cars still provided Americans about. seven times as much total mobility as planes and about. four times as much for intercity travel Figure 4 shows. a few of the glorious machines that AAPG has fueled. including the 1970 Chrysler Plymouth Road Runner, whose horn sounded like the beep beep of the popular. cartoon and guzzled gas Such vehicles have become, icons of automotive art and command fabulous prices. at auction among collectors,During AAPG s first century a lot of tinkering.

remained stable But finally,as our task is to look forward. another century we must admit,that in the long run electric. motors have many advantages, Figure 5 U S petroleum consumption 1900 2012 over internal combustion. Source USDOE Energy Information Administration 2013 engines They convert fuel to. Credit I Wernick and J Ausubel 2014 motion more efficiently with. more power density and they,do so quietly with instant torque. and no emissions The problem is the difficulty in storing electrons and then. the question becomes basically batteries or fuel cells. Despite a torrent of press releases I am skeptical about the progress of. batteries While their volumes have shrunk their weight improves only. very slowly We still need to carry around nearly a ton of batteries in a Tesla. inherently inefficient, Moreover batteries though rechargeable are not green Visit a lithium.
mine in northern Chile Texas would not permit such a facility and consider. trying to open one in California or Massachusetts And keep in mind that. lithium like lead and cadmium also popular for batteries is a poisonous. heavy metal This is another aspect of the fake news about new renewables. And consumers need a lot of mines and batteries A new battery for a full. size car stores 1 kWh Running New York City for two cloudy windless. days would require about 530 million such batteries about 62 per person. Meanwhile progress on fuel cells operating on hydrogen looks good. and companies such as Toyota and Honda bet heavily on it I believe that. General Motors has it right in their brochures that forecast vehicle and fuel. evolution through increased energy density over time as improved vehicle. fuel economy displaces petroleum and reduces emissions We need to take. very seriously the combo of hydrogen and fuel cells Today s package of a. fuel cell and a hydrogen storage tank weighs one third to one quarter of a. comparable battery package,10 Jesse H Ausubel, Key to Fake and True News About Energy and Environment. The energy gas the hydrogen to power the fuel cell will come first from. steam reforming of methane and later possibly from other methods By. mid century high temperature nuclear power plants could manufacture the. What of the hope that growth in markets in China and India will save. the car and thus petroleum My group at The Rockefeller University has. studied the demand in Japan and Korea as well as China and India Japan. and Korea saturated their petroleum demand like the USA but with about. one third less per capita Projections for China suggest consumption will. saturate at one third of Japan and India at one seventh Figure 6 Our. Austrian colleague the geographer Arnulf Gruebler has calculated that total. vehicle population in China will plateau about 0 2 per person which means. the total number of vehicles in China will max out about where the USA. is today After all although,China has four times as many. residents it has about the,How could the demand,for fuel and cars peak so low. First engineers of internal,combustion engines could. fight back and double their,efficiency Inevitably part.
of the story will be cars,operating on fuel cells or. batteries Part of the story is,GPS or more broadly sensors. autonomy and precision If Figure 6 Time and level of estimated oil saturation in four Asian nations. GPS means no one is ever lost Sources U S Energy Information Administration British Geological Survey. International Energy Agency,that saves a bunch of fuel. And there will be fewer cars per capita The auto industry needs to take. seriously the share economy made famous by AirBnB The average car. operates only about one hour per day If companies like ZipCar can cause. the average car to operate just two or three hours per day we will need less. rubber steel and glass for the same mobility and fewer parking spaces. Traffic can move better also saving fuel In 2013 alone the UPS company. estimates it saved 8 million gallons of oil by smart operations research that. made its fleet travel more efficiently, So markets in China and India and other developing countries will grow. but not enough to alleviate the squeeze on petroleum and they will saturate. in 2040 or so just a generation from now From an environmental point of. 11 Jesse H Ausubel, view this is good news The average vehicle will be much cleaner as Delhi.
and Beijing desperately need Another nasty problem that could diminish is. the global bloodbath called traffic An estimated 1 25 million people per year. die globally in traffic accidents about three times the deaths from malaria 2. Humans are dangerous drivers It is hard to see how self driving vehicles. once trained could do worse, If we could leap to 2040 from today we might say a revolution has. occurred but in practice these changes will evolve at something like. 3 percent per year but compounding over a generation causes a very. different system of motor vehicles and fuels, Importantly the reason for saturation of motor vehicles is not that. phones substitute for cars Communication and travel are complementary. goods The more we travel the more we communicate and the more we. communicate the more we travel Airports are full of people talking on. phones and airplanes are full of passengers now sending emails Here we. return to the travel time budget To range farther we need to shift from cars. to a much faster mode of transport namely planes, Aviation will grow and jet fuel can help geologists thrive for a while. The average American flies about 70 seconds per day much less than the. average member of the AAPG,and much more than the global. daily average excluding the,USA of about 12 seconds.
Of course hydrogen powers,rockets and could power planes. too directly or through fuel,Societies could also build a. new wave of faster transport,using linear motors a sequence. of electromagnets so called,magnetically levitated trains. For the past couple of centuries,societies have invested.

But evolution works relentlessly The density of energy consumption at. the level of the end user finally drives the system People keep moving into. cities and the energy consumption per square meter keeps rising Finally. only electricity and gases really thrive in cities Petroleum is incredibly great. stuff It gave all of us amazing freedom of movement and satisfied our most. basic instincts It gave every Texan the chance to have 400 horses and ride. low But the oil market is gated and attacked by richly armed electricity. and energy gases which have powers and attributes petroleum struggles to.
