Book excerpt: In Art & Energy, Barry Lord argues that human creativity is deeply linked to the resources available on Earth for our survival. From our ancient mastery of fire through our exploitation of coal, oil, and gas, to the development of today's renewable energy sources, each new source of energy fundamentally transforms our art and culture—how we interact with the world, organize our communities, communicate and conceive of and assign value to art. By analyzing art, artists, and museums across eras and continents, Lord demonstrates how our cultural values and artistic expression are formed by our efforts to access and control the energy sources that make these cultures possible.
