Net-Zero Carbon Dioxide Emissions By 2050 Requires A New Nuclear Power Plant Every Day

by Roger Pielke, Sep. 30, 2019 in WUWT

I research and write about science, policy and politics.

More than a decade ago, Gwyn Prins and Steve Rayner characterized climate policy as an “auction of promises” in which politicians “vied to outbid each other with proposed emissions targets that were simply not achievable.” For instance, among Democrats competing for the presidency in 2020, several, including Joe Biden, have committed to achieving net-zero carbon dioxide emissions by 2050. Candidate Andrew Yang bid 2049, and Cory Booker topped that by offering 2045. Bernie Sanders has offered a 71% reduction by 2030.

One reason that we see this “auction of promises” is that the targets and timetables for emissions reductions are easy to state but difficult to comprehend. Here I’ll present what net-zero carbon dioxide emissions for 2050 actually means in terms of the rate of deployment of carbon-free energy and the coincident decommissioning of fossil fuel infrastructure.

To conduct this analysis I use the BP Statistical Review of World Energy, which presents data on global and national fossil fuel consumption in units called “million tons of oil equivalent” or mtoe. In 2018 the world consumed 11,743 mtoe in the form of coal, natural gas and petroleum. The combustion of these fossil fuels resulted in 33.7 billion tonnes of carbon dioxide emissions. In order for those emissions to reach net-zero, we will have to replace about 12,000 mtoe of energy consumption expected for 2019. (I ignore so-called negative emissions technologies, which do not presently exist at scale.)

Another useful number to know is that there are 11,051 days left until January 1, 2050. To achieve net-zero carbon dioxide emissions globally by 2050 thus requires the deployment of >1 mtoe of carbon-free energy consumption (~12,000 mtoe/11,051 days) every day, starting tomorrow and continuing for the next 30+ years. Achieving net-zero also requires the corresponding equivalent decommissioning of more than 1 mtoe of energy consumption from fossil fuels every single day.

Another important number to consider is the expected increase in energy consumption in coming decades. The International Energy Agency currently projects that global energy consumption will increase by about 1.25% per year to 2040. That rate of increase in energy consumption would mean that the world will require another ~5,800 mtoe of energy consumption by 2050, or about another 0.5 of an mtoe per day to 2050. That brings the total needed deployment level to achieve net-zero emissions to about 1.6 mtoe per day to 2050.

Global energy demand to double by 2050

by Olbrew, July 20, 2019 in Tallbloke’sTalkshop

While many richer countries play fake climate games with their so-called ‘virtue signalling’ energy policies, the not-so-well-off majority try to get more access to those same power sources which are so necessary for better living conditions, e.g. air conditioning in hotter countries, and for general prosperity and health: more schools, hospitals, roads and all the rest.

Global power consumption will more than double over the next 30 years, says The Global Warming Policy Forum (GWPF).

Global oil and gas demand will respectively surge 22% and 66% from 2020 to 2050. There’s an unimaginable urbanization boom occurring around the world that means more energy use.

We, of course, don’t see much of it here in the West, but global cities swell in population by some 80 million people every year: e.g., the rise of the “megacity” with 10 million residents.

Basically all population growth in the decades ahead will take place in urban areas, all of which will be in the still developing nations (non-OECD), where poverty and insufficient access to energy is far more rampant than our worst nightmares could ever imagine.

Los Angeles targets eradication of petrol cars by 2050

Mayor unveils plan aiming for 100% zero-emissions vehicles by 2050 amid sweeping climate package for the city

Los Angeles’ car-choked arteries will run clean within decades, according to a green reform package unveiled by mayor Eric Garcetti on Monday.

Speaking only a week after New York City mayor Bill de Blasio announced his own framework climate legislation, Garcetti presented plans to revolutionise local car culture and green the city’s buildings, which together account for three-quarters of LA’s emissions.

“Los Angeles needs to lead, but the whole world needs to act. This plan gives us a fighting chance,” Garcetti told the Los Angeles Times. “It’s sort of a ‘greenprint’ for every other city in the country and the world, hopefully.”

The legislation, which builds upon a previous 2015 sustainability plan, calls on the city to hike its percentage of zero emission vehicles from 1.4% in 2018 to 25% by 2025, 80% by 2035 and 100% by 2050. To do this, the City Town Hall intends to raise its number of publicly available electric-vehicle chargers from 2,100 to 28,000.
