Everyone believes our primary problem is climate change
2
} What if there is a different, major issue, facing us much sooner?
} Like treating prostate cancer in a 60 year-old patient } Patient also has an aortic aneurysm } Aortic aneurysm could kill him near term } Miss the second, important diagnosis
} Maybe we need to examine the situation more closely

Standard story of limits misses the turning point
5
} Assumes prices of energy products will rise endlessly
} Assumes we need to supplement high-priced fossil fuels with high-priced renewables
} Data strongly suggests that energy prices have a turning point } Affordability becomes a problem
} Prices of commodities rise, then fall (turning point!) } Leads to bankruptcies of fossil fuel producers, merchant electricity
producers } Substituting high-cost renewables makes the problem worse } Danger is widespread bankruptcies
} Problems may spread to overall financial system, international trade

Affordability is the first energy-related limit of a finite world
We Are Here
Affordability

Falling affordability affects all commodities at once – including natural gas and coal
18
} Prices fall below the cost of production!!

Other factors besides rising energy costs contribute to falling affordability
19
} Rising “overhead” } More higher education, at high cost } Higher cost of medical care } Growing share of elderly
} Diminishing returns for other than energy } Fresh water—need desalination } Metals – require use of lower quality ores } Fish – catch larger number of smaller fish } Pollution control – more use of high-priced renewables
} Reduced wages due to globalization; automation

Implications for natural gas and
electricity
![Page 21: Our Electricity Problem: Getting the Diagnosis Correct · Our Electricity Problem: Getting the Diagnosis Correct Gail Tverberg from OurFiniteWorld.com – Oct. 15, 2015 . Everyone](https://reader033.vdocuments.us/reader033/viewer/2022053003/5f0715a47e708231d41b39a8/html5/thumbnails/21.jpg)
1. Don’t expect much growth in future natural gas supply
21
} Problem is low prices, because of affordability issues } No reason for affordability to get better
} Low price problem widespread } In the US } In Europe and Japan, for US imports
} Expect most natural gas to stay in the ground, forever
} Don’t expect a coal to natural gas transition } Can’t get the price up high enough, long enough
![Page 22: Our Electricity Problem: Getting the Diagnosis Correct · Our Electricity Problem: Getting the Diagnosis Correct Gail Tverberg from OurFiniteWorld.com – Oct. 15, 2015 . Everyone](https://reader033.vdocuments.us/reader033/viewer/2022053003/5f0715a47e708231d41b39a8/html5/thumbnails/22.jpg)

2. Expect use of coal to continue to decline in US electricity generation.
24
} Coal declined from 53% of total to 43% since 2004.

Coal prices are too low for most producers
25
} One cause—falling Chinese coal imports
} Bankruptcies likely } Alpha Natural Resources – already } Patriot Coal } Arch Coal } Glencore (international impact)
} Little reason for price condition to get better } Affordability of end products (houses, etc.) basic issue } Also over-production in face of falling demand
} Derivatives, debt distort production incentives

3. Expect coal and natural gas supply difficulties because of bankruptcies.
26
} Expect defaults on contracts for both coal and natural gas
} Natural gas – bankruptcy can lead to no new wells } New buyers can’t get financing at current low prices } Some continuing production from old wells, but not enough
} Coal – bankruptcy often leads to mine closures
} Fuel producers usually need loans to support operations } Need high prices for several years before lenders are willing to
lend again

4. Expect other types of bankruptcy-related problems as well
27
} Expect difficulty in getting parts for existing equipment } Replacement parts for wind turbines } Replacement parts related to solar PV installations } Replacement parts for coal, natural gas, nuclear generation } Transmission-related replacement parts
} Some customers may have financial difficulty } Trend in electricity demand likely to be flat or down, not up
} Do not believe upward trend forecast by EIA and IEA!
} May be government pressure to continue supplying electricity to those who cannot pay

5. Promised subsidies for wind, solar PV are likely to disappear
29
} If affordability affects workers, governments are affected as well } Governments cannot collect as high taxes as hoped for } Something must be eliminated } Subsidies likely to be cut
} High cost compared to coal and natural gas makes high-priced renewables look like a waste of money } Near-term cutback in subsidies seems likely

Overall cost of wind, solar PV (including transmission etc.) tends to be high

6. Ideal structure for electricity providers is that of vertically integrated utility
31
} Utility would have power to set prices on cost-plus basis } Gets around problem of low commodity prices } Allows electric grid to continue to operate, as long as possible
} Vertical integration would solve quite a bit of “bankrupt supplier” problem
} Example – Utility owning city hydroelectric dam
} Another example - Black Hills Corporation

7. On-site generation of electricity by multiple industrial organizations is problematic
33
} Each industrial organization will need to deal with bankrupt suppliers and parts providers
} Difficult for electricity providers to obtain an adequate price for backup generating services } Savings to existing electricity companies is small, if some
industrial organizations opt out } Primary savings is on fuel } Also, may be savings if annual peak can be cut
} Credit should reflect savings to the system
![Page 34: Our Electricity Problem: Getting the Diagnosis Correct · Our Electricity Problem: Getting the Diagnosis Correct Gail Tverberg from OurFiniteWorld.com – Oct. 15, 2015 . Everyone](https://reader033.vdocuments.us/reader033/viewer/2022053003/5f0715a47e708231d41b39a8/html5/thumbnails/34.jpg)
7. On-site generation of electricity by multiple industrial organizations is problematic (cont.)
34
} If only daily peak is cut, savings are minimal } Peaker plants need adequate profit } Leads to bankruptcy of peakers or need for subsidy
} If overall electricity demand is falling, transmission costs per kWh are likely to rise } If some industrial customers leave, trend exacerbated
} Another possibility – no grid connection at all for industrial organization } Eliminates problem of proper charge for backup

Conclusions
35
} Perhaps a major diagnosis has been missed.
} If our problem is low prices and bankruptcies, rather than high prices, then different solutions are needed. } Cost-plus pricing of the type used by utilities appears helpful.
} Renewables need replacement parts. They can’t be expected to last longer than other types of production.
} Don’t expect natural gas to replace coal.
} I have omitted discussion of financial and international trade issues. They may be important.
