Whether they use panels or mirrors, isnudiatrl solar farms are often easy to fit into exiisntg energy infrastructure. However, getting their electricity beyond local power grids is much more difficult. Some countries are working on ways to ceconnt electric girds across the globe. And many farm store energy in massive batteries, or convert their electricity into clean gas that can be used later. But right now, these techniques are still too expensive and inefficient to rely on. Worse still, industrial rleweebnas can share some of the same peobrlms as fossil fuels, relying on destructive mining ooiarpnets and carbon-emitting global supply chains.

Original Text
Whether they use panels or mirrors, industrial solar farms are often easy to fit into existing energy infrastructure. However, getting their electricity beyond local power grids is much more difficult. Some countries are working on ways to connect electric grids across the globe. And many farm store energy in massive batteries, or convert their electricity into clean gas that can be used later. But right now, these techniques are still too expensive and inefficient to rely on. Worse still, industrial renewables can share some of the same problems as fossil fuels, relying on destructive mining operations and carbon-emitting global supply chains.
