Challenge Climate Change

In the year 2017 already around 7,7 Bill. humans lived on the earth. The population on earth is further increasing. (UN Population Prospects 2017)

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. 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). 

 The latest number of the world population can be seen on:

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 (Energy Access Outlook 2017)

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 development about the amount of people with access to electricity were to be found e.g. on: https://www.iea.org/topics/energy-access

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

According to the World Energy Outlook  2023 (p.183 f.), 760 million people lacked access to electricity and almost 2,3 billion people were reliant on harmful cooking fuels: World Energy Outlook 2023 – Analysis - IEA  (last visit: 17. March 2025).

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