When Anna Speedy first heard that Totnes was going to create a brand-new musical about energy, community, and sustainability, she immediately knew she wanted her students to be part of it.
Exploring energy outdoors with emerging artists and communities
Given the punchy title you might think that Professor Dieter Helm, Oxford University's preeminent energy academic, has finally turned on the industry to which he is closely associated. Not so, Helm's narrative of a long-term decline, via a 'golden age for gas', is quite closely aligned with what oil and gas industry lobbyists are currently saying.
Regen worked with Western Power Distribution (WPD), Wadebridge Renewable Energy Network (WREN) and Tempus Energy to trial a Sunshine Tariff in Wadebridge, Cornwall.
The SWIMBY Songbook remains a resource for choirs and communities to perform, ensuring the project’s messages live on. It also paved the way for Regen’s continued interest in musical, performative, and participatory approaches to energy engagement.Matt reflects:“Energy projects can inspire music, laughter, and togetherness. SWIMBY was proof that climate action doesn’t have to be grim — it can be joyful.”
The Element in the Room showed that art can be more than an add-on to climate communication — it can be a catalyst for connection. By blending humour, lyricism, and celebration, Matt’s poetry helped make energy a subject people could relate to, enjoy, and even sing about. “Poetry gave people another way in — through fun, reflection, and imagination. That felt valuable.”
