Global CO2
emissions is the product of the CO2 emissions of the individual person
multiplied by the number of people in the world (more in the post on
Undesirable Green Developments from November 2019).
In 2014, the
environmental protection organization Ecopop (www.ecopop.ch) launched the
popular initiative “Stop Overpopulation - Safeguard our Natural Environment” in
Switzerland. The initiative called for government funding worldwide to promote
voluntary family planning.
The National
Councillor Balthasar Glättli (of the Greens) called Ecopop's aim to prevent
population growth with contraceptives abroad a “contemptuous, neocolonialist
attitude” (NZZ).
The reader will
no doubt have noticed that I am not a fan of parties like the Social Democratic
Party and the Greens that spread socialist ideas. But this is not about
political exchanges. The aim is to find out how the left and the Greens can
remove their ideological blinders so that they too can help lower the world’s
population in the next 50 years.
If we enable
voluntary family planning around the world, we will achieve two goals:
1. We
facilitate the living together of women and men in developing countries and prevent
abortions. More in the blog on Self-determined Sexuality in Developing
Countries from June 2019.
2. At the same
time, we help to reduce global warming.
We humans have to choose whether we
want to stop global warming with ascetic living or take other rational
measures.
In
industrialized countries, we should a l s o promote dropping the number of
children per woman to 1.2-1.6. (The population remains stable with 2.1 children
per woman). I believe that the number of children should not drop below 1.2,
because we need to ensure that old-age provisions are not endangered. The lack
of contributors to old-age provisions can only be partially replaced by
immigrants, as the willingness and ability of the local populations to accept
them should not be overestimated. With the number of children from 1.2 to 1.6,
some couples can also have 3 children, because there will be more and more
couples who have no children.
7.7 billion
people currently live in the world.
1.4 billion
live in industrialized countries. China, which is difficult to classify, also
has 1.4 billion.
This means that
almost 5 billion people live in emerging and developing countries.
CO2 emissions
are slowly declining in industrialized countries. China also wants to get there
in 10 years.
But the crucial
question will be how the CO2 emissions of emerging and developing countries
will develop.
There are
articles to the point of weariness in the media about global warming, but there
are no articles that deal with the issue above. Developing countries are only
recorded individually in the statistics.
Let's take
India as a “model state” for emerging and developing countries. There are
developing countries that are developing faster than India, but there are also
many that are developing more slowly.
India emitted
0.61 tons of CO2 per person per year in 1990 (Wikipedia: CO2 emissions per
capita). In 2020 the value will rise to around 2.0. So the value has more than
tripled in the past 30 years. We can assume that the value will also triple in
the next 30 years (by 2050). This means that CO2 emissions in the “model state”
of India will amount to 6.0 tons per person in 2050.
India
represents 5 billion people in the emerging and developing countries.
5 billion
people times 6.0 tons per person gives 30 billion tons of CO2. How much is 30
billion tons of CO2?
Global CO2
emissions in 2017 were 36.2 billion tons (Statista Research Department).
We have to
conclude that emerging and developing countries will emit huge amounts of CO2
in 2050, which cannot be compensated for by reducing the values in the
industrialized countries.
One can object
that India will also partially switch to alternative energy generation by 2050.
That may be, but the “model state” of India also stands in for Africa, and the
population in Africa will increase to about 2.5 billion by 2050.
The world
population is now 7.7 billion. Another 2 billion people will be added by 2050.
(The population is declining in industrialized countries, but the population is
increasing rapidly in the underdeveloped countries). How much CO2 will these 2
billion people emit in 2050? The experts have apparently never asked themselves
this question. Please let me know if you find any reports mentioning the above
question.
If we look at the development of
the world’s population, we can hardly assume that CO2 emissions can be
significantly reduced by 2050.
But maybe in
the next 10 or 20 years new methods for energy generation will be found that
make the switch to CO2-free energy generation easier than previously thought.
Photovoltaics:
If solar panels
are installed on roofs and exterior facades, electricity can be generated in a
very environmentally friendly way with photovoltaics.
However,
photovoltaics have one major disadvantage. In Central Europe, solar panels
generate 10 times less electricity in January than in July.
But we need a
lot of electricity in winter. Solar panels only make sense if we can build
storage facilities in which the electricity generated in the summer can be
stored for the winter, or we accept that additional electricity must be
generated in the winter with gas power plants. I will come back to electricity
storage later.
Wind energy:
Eight years ago,
I was in western Texas. There are large wind farms with very high towers. I
drove under a wind turbine that was surrounded by five others. A constant,
strong or very strong wind was blowing. There was an impressive roar. You could
feel that huge amounts of energy were being tapped here. It was as loud as if
three helicopters were taking off at the same time. But you couldn’t live near
there. I was amazed that they wanted to build hundreds of such plants in
Switzerland and Germany. There are too many dreamers and too few realists among
energy-system planners and journalists.
Offshore wind farms have a future. However,
if too many farms are built in a region (e.g. the North Sea), there is a risk
that the power grid will collapse if there is a lull.
The development
of floating wind turbines, which can be installed on the Atlantic coasts of
Portugal, France, Great Britain and the USA, is promising.
To stop
impending climate change, industrialized nations like the USA would have to
invest considerably more in basic research on energy supply, says Microsoft
founder Bill Gates. This also includes research on new types of nuclear
reactors, such as the so-called rotor reactor, the development of which is
being co-financed by Gates.
Bill Gates also said: “All technologies that
call themselves renewable are not reliable because they are not available in
sufficient quantities in all locations.”
We need
high-performance energy storage. The Linth-Limmern pumped storage power plant
is the newest and most powerful pumped storage power plant in Switzerland. It
has a storage capacity of 33 GWh. The annual consumption of electricity by the
city of Zurich is 3000 GWh. The Linth-Limmern pumped storage power plant could
only compensate for fluctuations in electricity production for the city of
Zurich for a few days. That’s surprisingly little, as the Linth Limmern
reservoir holds 23 million m3 of water and the height difference is 600 m.
Solar electricity from summer cannot be saved for winter this way. (Recommended article: https://www.bulletin.ch/de/news-detail/wasserkraft-versus-batterien.html
All
realistic-thinking natural scientists know that physics sets narrow limits when
it comes to building energy and storage facilities. There will be no miracle
facilities in the future!
The situation
is different in the IT area, where amazing developments can still be expected.
In the long
term, one of the biggest problems will be that the CO2 we release is extremely
slow to break down. About half of the CO2 released will be absorbed by the sea
and land after a few decades, but 15% to 40% of the CO2 will still be in the
atmosphere even after 1000 years (IPCC). This will have far-reaching
consequences.
