To reduce our ecological footprint clean technologies are begining to make a difference. Renewable Energies like windpower and solar power, geothermal and hydropower substitute more and more fossil fuels. Energy efficiency technologies are saving energy and money. The best energy is energy you do not need. Recycling, reuse, refurbish and sharing things and materials help to prevent environment pollution. Electric vehicles and the increased use of busses and trains also help to reduce the stress on our environment. Last but not least information technologies and shared knowledge can contribute to a better future. Education, clean water and air and sanitation are some of the basic needs, etc. For further informations and some facts please see, for instance: https://sdgs.un.org/goals or Energy Technology Perspectives 2023 - Event - IEA (release on 12.
