Solar is one of the fastest-growing energy technologies in the world today, and for good reason. The fuel is “free,” and systems for converting and collecting solar energy get more efficient all the time. Installations are scalable to function in vast arrays, on individual rooftops, in community installations, and even in portable form for use in disaster recovery or other temporary applications. And because the sun delivers its energy across the entire globe, solar power does not depend on the complex supply chains – trucks, trains, and pipelines – that fossil fuels require.
