MY LIGHT 5

My light falls on solar cells
and charges their electrons.

No turbines, no generators——

electricity streams across the cells,
which pour it into copper wires.

Electricity flows to the building below.

When darkness falls, you turn a switch.
From rushing wind and water,
from burning coal, from silent solar cells,
you let my energy into your room.
Electricity lights the night.

Inside a light bulb,
a wire grows hot.
It glows.

Inside a fluorescent tube,
gas is energized.
It glows.
