Greg Lynall’s Imagining Solar Energy is worth every metaphor of sunlight a reader might consider. It is a dazzling achievement: an intellectual highlight of recent literature and science scholarship that illuminates so much of our imaginative relationship to the sun across a stretch of time from the Renaissance to the present moment. Political in its interventions and global in its conceptualisations Imagining Solar Energy is also detailed, exacting, comprehensive. Taking in early seventeenth century pamphlets decrying renewable energy and twenty-first century solarpunk fictions wrestling with climate change Lynall offers a rich collection of entangled scientific, literary and cultural readings of the sun’s dangerous and restorative power. Striking for its erudition across solar sciences as well as literary periods, it will impress, too, for the eloquence of its environmental interventions.
