Had a bit of fun with this one! I enhanced those rays a little to create this effect I think it goes with that solar power theme with the sun and those electric pylons!
Goal 7 of the UN's Sustainable Development Goals is: Ensure access to affordable, reliable, sustainable and modern energy for all. There are great parallels to be made with the International Space Station. All our energy is completely carbon free as it comes from these beautiful, large, solar panels. They have been providing all the electricity we need up here for 20 years, but we have a great advantage: no clouds, so they get the full effect of our Sun. However half of our 90-minute orbit around is in the shadow of Earth, so batteries take over for 45 minutes to keep the electricity flowing, and they are recharged when we fly back into sunlight. As energy up here is a limited resource, a list exists where each facility is placed in order of priority. Representatives from the five space agencies that run the International Space Station work together to make the list so if ever power dips the top-priority facilities continue to run. I hear that the discussions around this can be quite lively as nobody wants their facility turned off, but for over 20 years researchers and mission designers have worked it out together and energy is continued to be produced and distributed. Like many things on the Space Station this is a nice example of what needs to be done on Earth, but obviously on a much larger scale and nobody is saying it is easy. Meanwhile after 20 years of service, the solar panels are getting ready for an upgrade with spacewalks planned to install new ones in the Summer. We need to safeguard our future energy to make it sustainable and continuous, just like on Earth.
Le 7e des Objectifs de développement durable de l'ONU : assurer l'accès pour tous à une énergie abordable, fiable, et durable. On peut faire plusieurs parallèles avec la Station spatiale internationale. Notre énergie est décarbonée car solaire: on voit assez nos immenses panneaux J. Ils fournissent toute l'électricité nécessaire ici depuis 20 ans, mais nous avons un gros avantage : l'absence de nuages :sunglass: Ils profitent pleinement du soleil, même si, à cause de sa trajectoire autour de la Terre, la Station spatiale passe constamment de l’ombre (côté non éclairé de la terre) à la lumière (côté éclairé).. d’où harge et décharge de grandes batteries extérieures. L'énergie étant une ressource limitée ici, les 5 agences spatiales qui gèrent la Station travaillent ensemble pour la gérer. En cas de problème électrique, il faut des priorités claires. En tout cas pendant plus de 20 ans, les chercheurs et les ingénieurs ont trouvé des solutions ensemble et l'énergie continue d'être produite et distribuée. Comme souvent sur l’ISS, c’est un bel exemple de ce qui doit être fait sur Terre, à plus grande echelle – c’est évidement beaucoup lpus difficile. Après des années de bons et loyaux services, les panneaux solaires donnent des signes de fatigue et des sorties extravéhiculaires sont prévues pour en installer de nouveaux au mois de juin. Ici aussi, on se creuse la tête pour render notre énergie plus durable.

One of my favourites of all time I just love the atmosphere, the colours and the moment in time!

Se riuscissimo a sfruttare di più l'energia che ci arriva dalla nostra cara stella Sole, vivremmo in un mondo più pulito e più sostenibile.

A macro shot of small solar cells on my pocket calculator. I guess that the dust gives a feeling for the size of the visible part of the solar cells.
Captured with my iPhone 8 and the "Black Eye" macro lens.
