This poster is part of a series produced by the Danish Trade Ministry’s Energy Saving Committee. It was created in response to the global energy crisis of the 1970s, an era distinguished by widespread oil shortages and inflated pricing. Each of the posters shows the word “spar” (save) emerging from a potential source of wasted energy—a lightbulb, a radiator, a hot shower, and a car. The crisis caused Denmark to explore and invest in new energy sources. By 2022, 67 percent of the country’s electricity was produced through renewable energy.
