World Energy 2016-2050: Annual Report

“Political Economist”

June 2016

The purpose of this annual report is to provide an analytical framework evaluating the development of world energy supply and its impact on the global economy. The report projects the world supply of oil, natural gas, coal, nuclear, hydro, wind, solar, and other energies from 2016 to 2050. It also projects the overall world energy consumption, gross world economic product, and energy efficiency from 2016 to 2050 as well as carbon dioxide emissions from fossil fuels burning from 2016 to 2100.

The basic analytical tool is Hubbert Linearization, first proposed by American geologist M. King Hubbert (Hubbert 1982). Despite its limitations, Hubbert Linearization provides a useful tool helping to indicate the likely level of ultimately recoverable resources under the existing trends of technology, economics, and geopolitics. Other statistical methods and some official projections will also be used where they are relevant.

Past experience with Hubbert Linearization suggests that Hubbert Linearization exercise tends to underestimate the ultimately recoverable oil and natural gas resources. To mitigate this “pessimistic” bias, I use the US Energy Information Administration (EIA)’s official projection to project US oil and natural gas production from 2016 to 2040, which may prove to be too optimistic.

About two years ago, I posted “World Energy 2014-2050” at Peak Oil Barrel (Political Economist 2014). The posts can be found here:

World Energy 2014-2050 (Part 1)

World Energy 2014-2050 (Part 2)

World Energy 2014-2050 (Part 3)

The 2014 report drew the following conclusion:

It finds that world production of oil, natural gas, and coal may peak between 2016 and 2031. As the supply of fossil fuels declines and the renewable energies do not grow sufficiently rapidly, the world energy consumption is projected to peak in 2035 and the world economy is projected to enter into a prolonged depression after 2040. World carbon dioxide emissions from fossil fuels burning are projected to peak in 2027. However, the cumulative carbon dioxide emissions from 2012 to 2100 are within the range of RCP 4.5 projected in the IPCC Fifth Assessment report, which may lead to long-term global warming of 3 degrees Celsius relative to the pre-industrial The summary statistics from the 2014 report are reported in the following table (Table 1).

These can be compared with the summary statistics reported towards the end of this report.

Since 2014, world energy conditions have significantly changed. Among the most important developments, the US production of oil and natural gas surged, leading to the collapse of world oil prices; China’s coal consumption and production have declined since 2013, leading to growing hope that the world economic growth may begin to “decouple” from carbon dioxide emissions. This report will show that this hope may be premature.

World Energy 2010-2015

According to BP’s Statistical Review of World Energy, world primary energy consumption reached 13,147 million tons of oil equivalent in 2015 (BP 2016). From 2010 to 2015, world primary energy consumption grew at an average annual rate of 1.5 percent.

World oil consumption (including biofuels) was 4,331 million tons in 2015, accounting for 33 percent of the world energy consumption. From 2010 to 2015, world oil consumption grew at an average annual rate of 1.2 percent.

World natural gas consumption was 3,135 million tons of oil equivalent in 2015, accounting for 24 percent of the world energy consumption. From 2010 to 2015, world natural gas consumption grew at an average annual rate of 1.7 percent.

World coal consumption was 3,840 million tons of oil equivalent in 2015, accounting for 29 percent of the world energy consumption. From 2010 to 2015, world coal consumption grew at an average annual rate of 1.1 percent.

World consumption of nuclear electricity was 583 million tons of oil equivalent in 2015, accounting for 4 percent of the world energy consumption. From 2010 to 2015, world consumption of nuclear electricity declined at an average annual rate of 1.4 percent.

World consumption of hydro, geothermal and biomass electricity was 1,010 million tons of oil equivalent in 2015, accounting for 8 percent of the world energy consumption. From 2010 to 2015, world consumption of hydro, geothermal and biomass electricity grew at an average annual rate of 3.0 percent.

World consumption of wind and solar electricity was 248 million tons of oil equivalent in 2015, accounting for 2 percent of the world energy consumption. From 2010 to 2015, world consumption of wind and solar electricity grew at an average annual rate of 23.9 percent.

According to World Bank and IMF data, gross world product (global economic output) was 107.0 trillion dollars (in 2011 constant international dollars) in 2015. From 2010 to 2015, global economic output grew at an average annual rate of 3.4 percent.

World average energy efficiency was 8,136 dollars per ton of oil equivalent in 2015. From 2010 to 2015, world average energy efficiency grew at an average annual rate of 1.8 percent.

World carbon dioxide emissions from fossil fuels burning were 33.5 billion tons in 2015. From 2010 to 2015, world carbon dioxide emissions grew at an average annual rate of 1.2 percent.

World average emissions intensity of gross world product was 0.313 kilogram of carbon dioxide emissions per dollar of gross world product. From 2010 to 2015, world average emissions intensity of gross world product declined at an average annual rate of 2.1 percent.

World average emissions intensity of primary energy consumption was 2.55 tons of carbon dioxide emissions per ton of oil equivalent. From 2010 to 2015, world average emissions intensity of primary energy consumption declined at an average annual rate of 0.3 percent.

Figure 1 compares the historical world economic growth rates and the primary energy consumption growth rates from 1991 to 2015. The primary energy consumption growth rate has an intercept of -0.011 at zero economic growth rate and a slope of 0.904. That is, primary energy consumption has an “autonomous” tendency to fall by 1.1 percent a year when economic growth rate is zero. When economic growth rate rises above zero, an increase in economic growth rate by one percentage point is associated with an increase in primary energy consumption by 0.9 percent. R-square for the linear trend is 0.751.

Oil

World oil production (including crude oil and natural gas liquids) was 4,362 million tons (91.7 million barrels per day) in 2015, 3.2 percent higher than world oil production in 2014.

In 2015, Saudi Arabia was the world’s largest oil producer by energy content; Saudi Arabia produced 569 million tons of crude oil and natural gas liquids (12.0 million barrels per day), accounting for 13 percent of the world oil production.

The United States was the world’s largest oil producer by volume; the US produced 567 million tons of crude oil and natural gas liquids (12.7 million barrels per day), accounting for 13 percent of the world oil production.

The Russian Federation was the world’s third largest oil producer; Russia produced 541 million tons of crude oil and natural gas liquids (11.0 million barrels per day), accounting for 12 percent of the world oil production.

Minqi Figure 2

Figure 2 shows the historical and projected US oil production from 1950 to 2050. Theprojection is based on the US Energy Information Administration’s reference case scenario of the US oil production from 2014 to 2040 (EIA 2016a), extended to 2050 based on the trend from 2031 to 2040.

The US cumulative oil production up to 2015 was 32 billion tons. EIA’s current projection implies that the US cumulative oil production will be 48 billion tons by 2040 and the US ultimately recoverable oil resources will be 160 billion tons. Hubbert linearization applied to the EIA projection from 2031 to 2040 implies that the US oil production will not peak until 2081 when production rises to 833 million tons.

Minqi Figure 3

Figure 3 applies the Hubbert Linearization analysis to the world (excluding the US) oil production. The world (excluding the US) cumulative oil production up to 2015 was 152 billion tons. The linear trend from 2009 to 2015 indicates that the world (excluding the US) ultimately recoverable oil resources will be 343 billion tons. Regression R-square is 0.956. Year 2009 is selected as the beginning year in estimating the linear trend because it was a year of global economic recession. Other things being equal, a recession year tends to have a lower current production to cumulative production ratio and result in a larger amount of estimated ultimately recoverable resources.

Minqi Figure 4

Figure 4 shows the historical projected world (excluding the US) oil production from 1950 to 2050. The world (excluding the US) oil production is projected to peak in 2021, with a production level of 3,811 million tons.

Minqi Figure 5

Figure 5 shows the historical and projected world production of liquid fuels. The world production of liquid fuels is the sum of the US oil production, the world (excluding the US) oil production, and the biofuels production. Projection of world biofuels production from 2016 to 2040 is from EIA (2016b), extended to 2050 based on the linear trend from 2030 to 2040. World production of liquid fuels is projected to peak in 2021, with a production level of 4,491 million tons.

Natural Gas

World natural gas production was 3,539 billion cubic meters (3,200 million tons of oil equivalent) in 2015, 2.2 percent higher than world natural gas production in 2014.

In 2015, the United States was the world’s largest natural gas producer; the US produced 767 billion cubic meters of natural gas (705 million tons of oil equivalent), accounting for 22 percent of the world natural gas production.

The Russian Federation was the world’s second largest natural gas producer; Russia produced 573 billion cubic meters of natural gas (516 million tons of oil equivalent), accounting for 16 percent of the world natural gas production.

Iran was the world’s third largest natural gas producer; Iran produced 193 billion cubic meters (173 million tons of oil equivalent), accounting for 5 percent of the world natural gas production.

Minqi Figure 6

Figure 6 shows the historical and projected US natural gas production from 1950 to 2050. The projection is based on the US Energy Information Administration’s reference case scenario of the US natural gas production from 2014 to 2040 (EIA 2016a), extended to 2050 based on the trend from 2031 to 2040.

The US cumulative natural gas production up to 2015 was 32 billion tons of oilequivalent. EIA’s current projection implies that the US cumulative natural gas production will be 55 billion tons of oil equivalent by 2040 and the US ultimately recoverable natural gas resources will be 156 billion tons of oil equivalent. Hubbert linearization applied to the EIA projection from 2031 to 2040 implies that the US natural gas production will peak in 2060 with aproduction level of 1,198 million tons of oil equivalent.

Minqi Figure 7

Figure 7 applies the Hubbert Linearization analysis to the world (excluding the US) natural gas production. The world (excluding the US) cumulative natural gas production up to 2015 was 72 billion tons of oil equivalent. The linear trend from 2009 to 2015 indicates that the world (excluding the US) ultimately recoverable natural gas resources will be 200 billion tons ofoil equivalent. Regression R-square is 0.777.

Minqi Figure 8

Figure 8 shows the historical and projected world (excluding the US) natural gas production from 1950 to 2050. The world (excluding the US) natural gas production is projected to peak in 2026, with a production level of 2,743 million tons of oil equivalent

Minqi Figure 9

Figure 9 shows the historical and projected world natural gas production. World natural gas production is projected to peak in 2030, with a production level of 3,694 million tons of oil equivalent.

Coal

World coal production was 7,861 million tons (3,830 million tons of oil equivalent) in 2015, 4 percent lower than world coal production in 2014.

In 2015, China was the world’s largest coal producer; China produced 3,747 million tons of coal (1,827 million tons of oil equivalent), accounting for 48 percent of the world coal production.

The United States was the world’s second largest coal producer; the US produced 813 million tons of coal (455 million tons of oil equivalent), accounting for 12 percent of the world coal production.

India was the world’s third largest coal producer; India produced 678 million tons of coal (284 million tons of oil equivalent), accounting for 7 percent of the world coal production.

Minqi Figure 10

Figure 10 shows the historical and projected US coal production from 1950 to 2050. The projection is based on the US Energy Information Administration’s reference case scenario of the US coal production from 2014 to 2040 (EIA 2016a), extended to 2050 based on the trend from 2031 to 2040.

The US cumulative coal production up to 2015 was 75 billion tons. EIA’s current projection implies that the US cumulative coal production will be 91 billion tons by 2040 and the US ultimately recoverable coal resources will be 155 billion tons. The US coal production peaked in 2008, with a production level of 1,063 million tons.

The world (excluding the US) cumulative coal production up to 2015 was 285 billion tons. According to BP (2016), at the end of 2015, the world’s total coal reserves were 891.5 billion tons and the world (excluding the US) coal reserves were 654.2 billion tons.

Minqi Figure 11

Figure 11 shows the historical and projected world (excluding the US) coal production from 1950 to 2050. The projection is based on the assumption that the world (excluding the US) ultimately recoverable coal resources will be 939 billion tons. The projected coal production curve is calibrated so that the world (excluding the US) coal production falls by about 140 million tons from 2015 to 2016. The world (excluding the US) coal production is projected to peak in 2040, with a production level of 8,115 million tons.

Minqi Figure 12

Figure 12 shows the historical and projected world coal production. World coal production is projected to peak in 2039, with a production level of 8,695 million tons.

Nuclear Electricity

World consumption of nuclear electricity was 2,577 terawatt-hours in 2015, 1.3 percent higher than world nuclear electricity consumption in 2014.

I use the US Energy Information Administration’s projection of nuclear generating capacity. According to EIA’s projection, world nuclear generating capacity will grow from 355 gigawatts in 2015 to 602 gigawatts in 2040 (EIA 2016b).

Minqi Figure 13

Figure 13 compares the observed capacity utilization rates for nuclear and renewable electricity.

The observed capacity utilization rate for electricity generation is calculated as follows:

Capacity Utilization Rate = (Annual Electricity Consumption * 2) / 8760 / (Beginning-of- Year Installed Capacity + End-of- Year Installed Capacity)

Electricity consumption data are from BP (2016). Electricity generating capacity data for years before 2010 are from the US Energy Information Administration, “International Energy Statistics.” Electricity generating capacity data for years after 2010 are from EIA (2016b).

From 2000-2010, the world average capacity utilization rate for nuclear generating capacity fluctuated around 85 percent. The average capacity utilization rate for nuclear generating capacity fell sharply during 2011-2014, due to the impact of the Fukushima accident. But it recovered to about 85 percent in 2015.

I assume that the average capacity utilization rate for nuclear generating capacity will be 85 percent for the period 2016-2040. From 2040 to 2050, nuclear electricity consumption is assumed to grow following the linear trend from 2030 to 2040.

Nuclear electricity is converted into its thermal equivalent using the formula: 4.4194 terawatt-hours = 1 million tons of oil equivalent (assuming 38 percent conversion efficiency in a modern thermal power plant).

Hydro, Geothermal and Biomass Electricity

World consumption of hydro electricity was 3,946 terawatt-hours in 2015, 1.0 percent higher than world hydro electricity consumption in 2014. World consumption of geothermal and biomass electricity was 518 terawatt-hours in 2015, 5.3 percent higher than world geothermal and biomass electricity consumption in 2014.

I use the US Energy Information Administration’s projection of hydro, geothermal and biomass generating capacity. According to EIA’s projection, world hydro generating capacity will grow from 1,079 gigawatts in 2015 to 1,473 gigawatts in 2040; world geothermal generating capacity will grow from 14 gigawatts in 2015 to 52 gigawatts in 2040; world biomass generating capacity (including other minor sources of renewable electricity) will grow from 132 gigawatts in 2015 to 275 gigawatts in 2040 (EIA 2016b).

In recent years, the world average capacity utilization rate for hydro, geothermal and biomass generating capacity has fluctuated around 42-43 percent (see Figure 13). I assume that the average capacity utilization rate for hydro, geothermal and biomass generating capacity will be 43 percent for the period 2016-2040. From 2040 to 2050, hydro, geothermal and biomass electricity consumption is assumed to grow following the linear trend from 2030 to 2040.

Hydro, geothermal and biomass electricity is converted into its thermal equivalent using the formula: 4.4194 terawatt-hours = 1 million tons of oil equivalent (assuming 38 percent conversion efficiency in a modern thermal power plant).

Wind and Solar Electricity

World consumption of wind electricity was 841 terawatt-hours in 2015, 17.4 percent higher than world wind electricity consumption in 2014. World consumption of solar electricity was 253 terawatt-hours, 32.6 percent higher than world solar electricity consumption in 2014.

In 2015, the world installed 63 gigawatts of wind generating capacity and 51 gigawatts of solar generating capacity.

Minqi Figure 14

Figure 14 compares the historical relationship between total annual installation of wind and solar power and the annual growth to the annual installation ratio (that is, the ratio of the growth of the annual installation to the annual installation). The downward inear trend (R-square 0.262) indicates that the total annual installation of wind and solar power should eventually approach the maximum of 176 gigawatts (where the linear trend meets the zero horizontal line).

The parameters of the linear trend can be used to project the future installation of wind and solar power. While the linear trend is preliminary, the implied future installation compares favorably against several mainstream forecasts.

Minqi Figure 15

Figure 15 compares this author’s forecast of future installation of wind and solar generating capacity with the “GWC/IHS Forecast” and the US Energy Information Administration’s official forecast published in EIA’s International Energy Outlook (EIA 2016b).

According to Global Wind Energy Council’s current forecast, the world will install 64 gigawatts of wind generating capacity in 2016, 68 gigawatts in 2017, 72 gigawatts in 2018, 75.5 gigawatts in 2019, and 79.5 gigawatts in 2020 (GWEC 2016). According to energy consultancy IHS's forecast, the world will install 65 gigawatts of solar generating capacity in 2016, 65.5gigawatts in 2017, 68.4 gigawatts in 2018, and 73.5 gigawatts in 2019 (Beetz 2015). I extend IHS's forecast to 2020 by assuming that the world will install 78.5 gigawatts of solar generating capacity in 2020. If one adds up GWEC’s forecasts of wind installations and IHS's forecasts of solar installations (extended to 2020), then the world’s cumulative installation of wind and solar generating capacity should rise to 1,375 gigawatts by 2020. By comparison, this report (“World Energy 2016-2050”) projects that the cumulative installation of wind and solar generating capacity will be 1,373 gigawatts by 2020.

This report’s forecast of future wind and solar installation is far more optimistic than the US Energy Information Administration’s official forecast. According to EIA’s forecast, the world’s cumulative installation of wind and solar generating capacity will be 865 gigawatts by 2020 and 1,512 gigawatts by 2040. By comparison, this report projects that the world’s cumulative installation of wind and solar generating capacity will rise to 4,826 gigawatts by 2040 and 6,585 gigawatts by 2050.

In recent years, the world average capacity utilization rate for wind and solar generating capacity has fluctuated around 20-22 percent (see Figure 13).

I assume that the average capacity utilization rate for wind and solar generating capacity will be 22 percent for the period 2016-2040. Wind and solar electricity is converted into its thermal equivalent using the formula: 4.4194 terawatt-hours = 1 million tons of oil equivalent (assuming 38 percent conversion efficiency in a modern thermal power plant).

Wind and Solar Electricity Generation Cost
As the wind and solar electricity cost falls, it has become increasingly controversial regarding whether wind and solar electricity has become “cost competitive” against fossil fuels power plants.
This section uses a simple and transparent framework that compares the wind and solar electricity generation costs with the gas-fired electricity generation cost.
The average electricity generation cost is defined as the annual total generation cost divided by the annual electricity generation.
The annual electricity generation from one gigawatt of generating capacity is calculated as follows:

Annual Electricity Generation = 1 Gigawatt * Capacity Utilization Rate

In the US, gas-fired electricity serves as both base-load and load-balancing power. I assume that the gas-fired power plant has a capacity utilization rate of 50 percent.
In 2015, the world average observed capacity utilization rate for wind electricity was 24 percent and for solar electricity was 14 percent. The US had higher observed capacity utilization rates. The US observed capacity utilization rate for wind electricity was 31 percent and for solar electricity was 20 percent (calculated using data from BP 2016).
I assume that the wind power plant has a capacity utilization rate of 30 percent and the solar photovoltaic power plant has a capacity utilization rate of 20 percent.
The annual total generation cost is the sum of annual fixed cost and annual fuel cost.
Annual fixed cost is assumed to be 10 percent of the capital cost. Annual fixed cost includes interest rate (assumed to be 5 percent) and depreciation and maintenance cost (assumed to be 5 percent of the capital cost).
Wind and solar electricity has no fuel cost. For gas-fired electricity, the technology is assumed to be advanced combined cycle. Natural gas consumption for gas-fired electricity is calculated assuming 55 percent thermal conversion efficiency (or a heat rate of 6,200 British thermal units per kilowatt-hour) and natural gas price is assumed to be 5 dollars per million British thermal unit (in 2015, the US Henry Hub natural gas price was 2.6 dollars per million Btu).
Table 2 reports the estimated generating cost for gas-fired, wind, and solar photovoltaic electricity. Given the current technologies, gas-fired electricity costs 5.6 cents per kilowatt-hour, wind electricity costs 6 cents per kilowatt-hour, and solar photovoltaic electricity costs 14 cents per kilowatt-hour. Wind electricity costs about the same as the gas-fired electricity and solar photovoltaic electricity is about two-and-a-half times as expensive.

Table_2/

Limits to Wind and Solar Electricity

In the medium- and long run, wind and solar electricity will be constrained by their intermittency and the growing difficulties to incorporate them into the electric grid.

An article published in China Electric Power studied the problem of incorporating wind and solar electricity into the electric grid of China’s Gansu province (a Chinese province is about the size of an European country). As of 2013, Gansu province had 12 gigawatts of wind generating capacity and 5.3 gigawatts of solar photovoltaic generating capacity (Yao, Zheng, and Li 2014). By comparison, Spain had a total installation of wind and solar generating capacity of 16 gigawatts in 2007.

The conventional generating capacity that is available for load balancing can be calculated from the following formula:

P L = (P total – Grid Reserve – Plant Self-Consumption and Transmission Losses) * “Balancing Depth” Factor

In the above formula, P total is the total nameplate conventional generating capacity. P L is the conventional generating capacity available for load balancing. The authors of the study subtracted 13 percent of the total capacity as the “reserve capacity.” Power plant self- consumption and transmission losses are assumed to be 10 percent of the electricity generated.

“Balancing Depth” refers to the degree to which the conventional generating capacity can increase or decrease generation on short notice. This is assumed to be 30 percent of the effective generating capacity. Thus, overall, only about 23 percent of the nameplate conventional generating capacity is actually available for load balancing.

Out of the conventional generating capacity that is available for load balancing, some has to be used to meet peak load demand that is not offset by wind or solar generation. This is estimated to be about 20 percent of the average load or 10 percent of the total nameplate capacity. Thus, only 13 percent of the nameplate conventional generating capacity is available to balance the intermittency of wind and solar electricity.

In the case of Gansu province, it was estimated by the authors that for 17 gigawatts of wind and solar power, load balancing need would be 7-9 gigawatts or between 40 and 55 percent of the wind and solar generating capacity. Take the lower limit of 40 percent. As the balancing need of wind and solar generating capacity is 40 percent and only 13 percent of the conventional generating capacity is available for balancing the intermittency of wind and solar electricity, it follows that the total conventional generating capacity needs to be about three times as large for the electric grid to be balanced (40 / 13 = 3.08).

Let us make some optimistic assumptions. Suppose the grid reserve can be reduced to 10 percent of the total nameplate conventional generating capacity and the balancing depth can be increased to 50 percent. Thus, 40 percent of the nameplate capacity can be made available for

load balancing. Subtracting 10 percent of the capacity required to meet peak load demand, 30 percent of the nameplate conventional generating capacity can be made available to balance wind and solar intermittency.

On the other hand, suppose through better coordination and building of long-distance transmission lines, the balancing need for wind and solar electricity can be reduced to 30 percent of the generating capacity. After these adjustments, it would still take at least one gigawatt of conventional generating capacity to match one gigawatt of wind or solar generating capacity.

According to EIA’s International Energy Outlook, the world will have 1,970 gigawatts of coal-fired generating capacity, 2,252 gigawatts of gas-fired generating capacity, 320 gigawatts of liquids-fired generating capacity, and 1,473 hydroelectric generating capacity by 2040. Thus, by 2040, the total conventional generating capacity adds up to 6,015 gigawatts.

According to this report’s projection, the world will have 4,826 gigawatts of wind and solar generating capacity by 2040 and 6,586 gigawatts by 2050. Thus, the technical limits of the world’s electric grids to accommodate wind and solar electricity will be tested by the 2040s.

In the very long run, the expansion of wind and solar electricity will be constrained by the availability of land and material resources.

According to Castro et al. (2011), global technical potential for wind electricity generation is about one terawatt. The materialization of this potential would require the building of wind electric power over a land area as large as 10 million square kilometers. Assuming a capacity utilization rate of 25 percent for wind power, it takes 4,000 gigawatts of wind generating capacity to generate one terawatt of wind electricity.

The current global land occupation by human settlement and infrastructure is estimated to be 2-4 million square kilometers or 1.3-2.7 percent of the world’s total land surface area. In the next few decades, 1 million square kilometers of additional land will be occupied for human settlement and infrastructure because of population growth and urbanization. By the end of the century, there will be about 4-6 million square kilometers occupied by human settlement and infrastructure. If 10 percent of the total settlement and infrastructure land area can be made available for solar electric power, the total land area where the solar electric power can be built will amount to about 500,000 square kilometers by the end of the 21st century.

Assuming a power density of 4 watt per square meter, a land area of 500,000 square kilometers can generate solar electricity of two terawatts or 2,000 gigawatts (Castro et al. 2013).

Assuming a capacity utilization rate of 15 percent for solar power, 2,000 gigawatts of solar electricity generation requires about 13,000 solar generating capacity.

Thus, by the end of the 21st century, the world has a total technical potential of wind and solar generating capacity of about 17,000 gigawatts. According to this report’s projection, the world will have built about 6,600 gigawatts of wind and solar generating capacity by 2050.

Beyond 2050, if the world keeps building 175 gigawatts of wind and solar generating capacity each year, the world will have more than 15,000 gigawatts of wind and solar generating capacity by 2200. This is consistent with the technical potential estimated above.

Figure 16 shows the historical and projected world primary energy consumption from 1950 to 2050.

World historical consumption of oil, natural gas, and coal from 1950 to 1964 is assumed to be the same as production.

World primary energy consumption and its composition from 1965 to 2015 is from BP (2016).

World consumption of oil, natural gas, and coal from 2016 to 2050 is assumed to be the same as production. Oil consumption includes biofuels. Coal production in tons is converted to coal consumption in tons of oil equivalent using the formula: 2.05 tons of coal production = 1 ton of oil equivalent of coal consumption (based on the observed relationship in 2015).

World consumption of nuclear, hydro, geothermal, biomass, wind, and solar electricity from 2016 to 2050 is based on projections explained in the above sections.

World primary energy consumption is projected to peak in 2043 at 16,333 million tons of oil equivalent.

For 2016-2050, the relationship between the primary energy consumption growth rate and the economic growth rate is defined as follows:

Economic Growth Rate = (Primary Energy Consumption Growth Rate + 0.0112) / 0.904

In other words, it is assumed that the trend relationship between the two variables observed for the period 1991-2015 will continue to hold for the period 2016-2050.

Minqi Figure 17

Figure 17 shows the historical and projected world economic growth rates from 1951 to 2050. World (trend) economic growth rate is projected to fall below 3 percent by the 2020s, fall below 2 percent by the 2030s, and approach 1 percent by the 2040s.

After the Second World War, global economic growth rate fell below 2 percent only in several occasions: 1975, 1982, 1991, and 2009. These were all considered to be deep global economic recessions. During 1913-1950, when the global capitalist system suffered from major wars, revolutions, and the Great Depression, world economy actually grew at an average annual rate of 1.8 percent (Maddison 2010).

Thus, by the mid-21st century, although the global economy will continue to grow, world economic growth rate may become too close to zero so that the global capitalist system will suffer from persistent economic and political instability.

Minqi Figure 18

Figure 18 shows the world carbon dioxide emissions from fossil fuels burning from 1950 to 2100.

Carbon dioxide emissions are estimated using oil, natural gas, and coal consumption data from BP’s Statistical Review of World Energy. In previous editions of Statistical Review of World Energy, BP used the following conversion factors to calculate carbon dioxide emissions: 1 ton of oil emits 3.07 tons of carbon dioxide; 1 ton of oil equivalent of natural gas emits 2.35 tons of carbon dioxide; 1 ton of oil equivalent of coal emits 3.96 tons of carbon dioxide. In the 2016 edition of Statistical Review of World Energy, BP revised the estimates of carbon dioxide emissions without providing conversion factors for fuel types.

I estimate the carbon dioxide emissions from oil, natural gas, and coal consumption by using the conversion factors provided in previous editions of Statistical Review of World Energy and multiplying the conversion factors by an adjustment factor. The adjustment factor is 0.97 for 1965-1970, 0.96 for 1971-1980, 0.95 for 1981-1990, and 0.94 for 1991-2100. For example, carbon dioxide emissions from oil consumption in 1965 are estimated as: oil consumption in 1965 * 3.07 * 0.97. For years after 1990, biofuels production is subtracted from oil consumption in estimating carbon dioxide emissions from oil consumption. The total carbon dioxide emissions so calculated are very close to the carbon dioxide emissions reported by BP (2016) for the period 1965-2015.

World carbon dioxide emissions are projected to peak in 2029 at 35,953 million tons.

Cumulative world carbon dioxide emissions from fossil fuels burning from 2011 to 2100 will be 2,432 billion tons. These are emissions from direct fossil fuels combustion only and do not include emissions from cement production and gas flaring.

According to Intergovernmental Panel on Climate Change’s Fifth Assessment Report, cumulative carbon dioxide emissions of 2.4 trillion tons from 2011 to 2100 are within the range of “representative concentrated pathways” RCP 4.5. It will lead to atmospheric concentration of carbon dioxide equivalent of 650 parts per million by 2100 and result in a median estimate of global warming of 2.6 degrees Celsius by 2100 (compared to 1850-1900), with about one-third chance that global warming by 2100 may actually exceed three degrees Celsius (IPCC 2014, Table SPM.1).

According to Hansen et al. (2015), global warming by more than two degrees may lead to the melting of West Antarctica ice sheets, causing sea level to rise by 5-9 meters over the next 50-200 years. Bangladesh, European lowlands, the US eastern coast, North China plains, and many coastal cities will be submerged. This will lead to the end of civilization as we know it.

If global warming rises above three degrees Celsius, slow climate feedbacks (through ice sheet melting and vegetation change) may eventually lead to a long-term global warming by up to six degrees Celsius (Hansen et al. 2008). In that event, much of the world will no longer be suitable for human inhabitation.

    Not a bad piece of work but going off about climate change and the fantasy land predictions of Dr. Doom does the article no service. Almost every scientist in the world knows climate change is a hoax. Not a misinterpretation of the data sets. A hoax! Wait until the global cooling kicks in. Then you’ll see.

    Global cooling? Are you fucking retarded?

    “Almost every scientist in the world knows climate change is a hoax. Not a misinterpretation of the data sets. A hoax! Wait until the global cooling kicks in. Then you’ll see.” Only 2 type of persons would say what u just said. Either an extreme idiot or someone with an agenda

    “Hubbert linearization applied to the EIA projection from 2031 to 2040 implies that the US oil production will not peak until 2081 when production rises to 833 million tons.”

    So I did a Google search for how many barrels in a ton of oil and I got 7 as the answer. So that’s 119 million barrels. Does he mean EIA is saying USA will produce 119 million barrels a day in 2081?

    “So I did a Google search for how many barrels in a ton of oil and I got 7 as the answer. “

    How many barrels in a tonne depends on the API density of the oil. API 37.5° crude has 302.1376 lbs per barrel. Reference to a tonne is usually a metric tonne, which is 2200 lbs. Therefore there is 7.282 barrels of API 37.5° crude in a tonne. This is the number that is most commonly quoted, although the Russians use a different value. Their standard, the Ural grade, is API 32.7° so it comes out to about 7.1 barrels per tonne.

    It looks like PO News’ server is having a bad day – it posted the last one twice, after it refused to post it at all.

    ““Hubbert linearization applied to the EIA projection from 2031 to 2040 implies that the US oil production will not peak until 2081 when production rises to 833 million tons.” “

    That statement makes absolutely no sense at all! 833 million tonnes is 6.07 Gb, or 16.63 mb/d. This whole article is just someone who has figured out how to do a Hubbert linearization, and got some graphing software. They either had a lot of spare time on their hands, or were being paid by the word. This is not a model; it is curve fitting exercise with no consideration given to the limits to which extrapolation can be taken. The historical production cost curve separated from the historical price curve in 2012. By ignoring that simple fact all kinds of ridiculous claims are easy to make.

    We are seeing these types of exercises routinely in the MSM and internet world of people selling agendas or just plain news reporting ignorance. We see it across the spectrum of topics important to man. This represents a habituated conditioning to growth based thinking. It is intellectual laziness combined with denial of destructive change at the highest levels. We are frankly in a surreal world of dramatic change with a population which is unable to understand or embrace.

    It is actually normal human behavior that has manifested itself throughout modern man’s history of last several thousand years to be deceived from reality. Today we think we should know better because of all the data we have at our finger tips but this is part of the problem. We have too much information which is as bad as too little. Many of us here and on other sites are the modern day prophets and like prophets throughout time we will be disregarded by most. Many of us prophets are also deceiving ourselves thinking we have the answers. What a mess we are in

    I saw an article on Fox today mentioning the melting permafrost in Siberia and mentioning the feedback loop, you know your PHD was printed off the internet when even FOX has a less science denying stance than you do.

  14. Outcast_Searcher on Tue, 21st Jun 2016 11:18 am 

    Well Javier, Mr. PhD.

    Why don’t you show us your source(s) to show why you believe (and we should believe) that “Almost every scientist in the world knows climate change is a hoax. Not a misinterpretation of the data sets. A hoax!”

    I will certainly agree that almost every far right wing nut job blogger believes this. But I very much doubt you can show multiple CREDIBLE sources that backs you up on this for scientists.

    Until we see credible sources for your claim, you have zero credibility.

  15. Davy on Tue, 21st Jun 2016 11:45 am 

    Respect for what people say on this board comes with time as far as I am concerned. Anyone can bop in and out without skin in the game. Anyone new I give a handicap to especially depending on what they say and how they say it. I don’t care if it is what I like to hear or not. What I like is honesty and integrity and that comes with effort and dedication of the message. Javier currently is on my Joke list for what he said, how he said it and his recent arrival status.

  16. Survivalist on Tue, 21st Jun 2016 10:09 pm 

    @short

    How did you get “833 million tonnes is 6.07 Gb, or 16.63 mb/d”.

    What factor are you using to convert tons to barrels?

  17. Survivalist on Tue, 21st Jun 2016 10:13 pm 

    OK I got it now. I thought he was saying daily production in tons but he means annual lol duh! I wish the article specified production in time not just mass.

  18. Truth Has A Liberal Bias on Wed, 22nd Jun 2016 12:28 am 

    Lol “skin in the game”- do you even know what that means Davy? How does one have ‘skin in the game’ on a comments board that poaches articles from other sites and reposts them? You are possible the biggest fucking retard on this pathetic website. ‘Skin in the game’ lmfao did you buy shares or something? what a fucking loser!

  19. Davy on Wed, 22nd Jun 2016 6:30 am 

    (Not) Truth, you are demonstrating your cognitive dissonance. You are definitely spooked and it shows with every dumb thing you say.
