Have you ever thought about what would happen if the whole world went solar?
One of the things we continue to reach for is a future that is clean and safer. With this, renewable energy easily fits into the category of things that will make this achievable for us. With climate change rapidly manifesting its effects and fossil fuel running out, we need to quickly find a resolution.
Imagine the whole world going solar
Nature Climate Change was able to conduct and publish a study wherein researchers assessed climate models in order to investigate the result of what would happen if the entire world converted its entire energy supply to solar. They adopted the situation of solar panels being installed in regions where the supply of sunlight is greatest like major desert regions and urban areas where the demand for power is just as high.
The average temperature will drop by 2°c.
This change is very minute on a global scale but in a scope that is more narrowed down. The changes caused by this small drop in temperature can be observed better. The widespread use of solar panels contributed to global cooling, due to them absorbing all the solar radiation which would have otherwise been absorbed by the ground, imparting in the increase in global temperatures.
Decrease of solar radiation by 19%.
They also found out that this has the potential of decreasing solar radiation by 19% in desert areas. This would result in the cooling of the environment.
Less rain and clearer skies.
In line with the changes they predicted, the most evident modifications would happen in the deserts. The presence of precipitation in deserts or the creation of water vapour in the air has the potential to decrease by 20% due to the cloud reduction caused by solar panels. This would result in the lessening of rain, snow, sleet, and even hails in the areas concerned.
Moreover, desert cooling could cause changes in wind patterns, jet stream locations, and alterations of precipitation. This applies in many different regions such as Asia, the Middle East, Australia, and the tropical Pacific. Mentioned areas have the possibility to lose up to 25 centimetres of average annual precipitation. This could instead shift to Europe, North Pacific, western North America, tropical Africa, and the southeast Indian Ocean.
Their study does provide results presented under an extreme scenario – assuming that 100 per cent of land areas in both cities and deserts would be making use of solar panels, which is far from realistic. In line with this, they made an alternate model that would better reflect the future demands for energy and power.
In this scenario, solar panels will be installed in urban areas worldwide and a small portion of the Egyptian desert. This covers only 10% of the total land area purposely allocated to solar panels in the primary version of their model. They compared results to the magnified version of the model such as drops in temperature but in this version, changes are much more minuscule. They found temperature declined by 0.04 degrees Celsius, instead of a full 2.
These are still observable changes that can bring about bigger ones in the years to come. Evergreen Solar can be your partner in taking that step into a brighter, safer, and cleaner future. We want to take these ideas and turn them into our reality. We only aim to leave good changes and not environmental footprints.
