In the year 2017 already around 7,7 Bill. humans lived on the earth. The population on earth is further increasing. (comp.: UN Population Prospects 2017,  URL: https://www.un.org/development/desa/publications/world-population-prospects-the-2017-revision.html

Approximately at maximum one fourth of humanity lives in industrialized countries. More and more humans want a higher standard of living. This increases the consumption of natural living-basics like natural resources, raw material, and energy. The latest number of the world population can be seen on  https://bevoelkerung.population.city/world/ (last visit: 02. April 2021) . On 02. April 2021 it was already more than 7,827 billion humans.

On 15. November 2022 the number of inhabitants of planet earth to reach over 8 billion: https://www.un.org/en/desa/world-population-reach-8-billion-15-november-2022 ,last visit: 15.Nov.2022. or: World Population Clock: 8.1 Billion People (LIVE, 2024) - Worldometer (worldometers.info) , last visit: 9.

Some say there would be enough food and enough resources for more than 12 billion people, if we all would act sustainable and fair around the globe.

In the year 2017 around one billion humans had no access to electricity and more than 2,5 billion humans had no access to clean energy for a warm meal ( compare.: Energy Access Outlook 2017, URL: www.iea.org/access2017 (last visit: 03. March 2019))

Many humans have no clean water and no medical service. Many humans live under inhuman conditions. The access to daily energy is a basic precondition for a human existence. The momentary development about the amount of people with access to electricity can be found e.g. on: https://www.iea.org/topics/energy-access (last visit: 02. April 2021) .

The Covid-19-pandemic has turned down the positive development of the last years.

The energy supply for the whole humanity based on renewable energy carriers from the sun, wind, biomass and geothermal is possible. This is researched by studies like e.g. studies from the Energy Watch Group and the Suomi LUT, compare: URL:
