We\u2019ve been talking about how sunlight could be the key to a cleaner future for quite some time now. So much so that photovoltaic panels have been popping up on urban rooftops and in remote deserts, while governments and companies have been banking on the promise of solar energy as one of the most viable solutions to the climate crisis. But what if there were another way to use the sun to save the planet\u2026 we\u2019re talking about a way that doesn\u2019t involve collecting its light, but partially blocking it.<\/span><\/p>\n

A new non-photovoltaic invention<\/h2>\n

Of course, it may seem contradictory when you hear it like this. After all, why would anyone try to reduce solar radiation if we are trying to make the most of it? Well, the answer lies in a controversial and, at the same time, fascinating idea: <\/span>using the Sun’s own shadow to balance the Earth<\/b>. In technical terms, the name of this proposal is atmospheric sun shading. This technology is nothing more than a solar geoengineering technique that aims to reflect part of the sunlight before it reaches the Earth’s surface, helping to cool the planet and mitigate the effects of global warming.<\/span><\/p>\n

Okay, but does this work in practice? The most studied idea so far involves injecting sulfur dioxide particles into the stratosphere. Basically, we would be simulating the effect of large volcanic eruptions which reduced global temperatures for about two years. And then, these particles would form a thin layer that reflects part of the solar radiation back into space, creating a kind of planetary sunshade. In theory, this could reduce global average temperatures in the short term, offering a breathing space while other structural solutions evolve.<\/span><\/p>\n

Is atmospheric sun shading worth it?<\/h2>\n

In order to better understand whether this new non-photovoltaic technology is worth it or not, we have separated the advantages and risks involved in this project. Let’s take a look at them.<\/span><\/p>\n
