The Yellow Marble Project

Signifying our Sun. Gifting a yellow marble gives thanks to those advancing sustainable energy.

One source, many sources of energy

Nearly all energy is gifted us by the Sun. From sunlight that sparks life in living, and long buried, plants and animals. To photons that knock electrons loose in solar panels. From winds that turn our mills and turbines. To the ocean tides that rise and fall. From the evaporation of water that eventually cycles as rain to be stored and released in hydroelectric systems. To the gravity that pulled our planet together and heated its molten core. It is all borne of the Sun. And it is all conserved.

From one source, many.


Energy conserved, energy shared

Engineers will tell you. All energy is conserved. It cannot be created or destroyed. Therefore, the simple act of passing a marble from one person to another is the act of passing energy from one hand to the next. Pass it on.

A simple near-valueless object can take on great value as a symbol when given with purposeful intention; and sustainability action.


Pass it on

If you've been gifted a yellow marble and would like to share a photo, please post to social media #yellowmarbleproject and we'll pick it up from there.

...and if you would like to buy a bag of yellow marbles for gifting, please do. We don't sell them here.
