EARTH HOUR

Once a year, all over the world, people celebrate the electricity we use in our daily lives by turning off lights in homes, offices, and famous monuments for a single Earth Hour.

In time for next spring’s Earth Hour, March 29, 2020, this admirable debut offers both the what and the why. Luu’s cheery illustrations emphasize the worldwide nature of this event. The book begins with vignettes: examples of electricity use, including cozy home scenes, city streets, and the lit-up Earth as seen from space. Next, full pages and double-page spreads show illuminated buildings, cities, and internationally recognizable monuments at night. The scenes then move to the interior: bathtime, family games, and lights out. The international scenes reappear, without artificial light. The next to the last spread shows a single sleeping child (echoing Clement Hurd’s “great, green room”); the final one shows people of many colors and ethnicities (one using a wheelchair) carrying candles and lanterns on a starlit night: “Alone we are one… // …but together we have power. / United, we are Earth Hour.” Heffernan’s simple narrative runs across the pages, tying the story together. Her author’s note recalls her surprise at seeing San Francisco’s Golden Gate Bridge go suddenly dark in honor of Earth Hour a few years ago, and a short final note connects energy use to global climate change.

A timely invitation to participate in raising energy consciousness.
