At the head of a new wave of energy-efficient lighting is the SunUmbra tree, a solar-powered tree that offers both shade and light in remote public areas.

Designed by Loop.pH, the tree is made up of light-emitting fabric woven into a large webbed lattice of branches, which offers shade and while absorbing light during the day with its photovoltaic panels.

Implications - The rise of environmentalism has caused designers to envision sustainable public fixtures and lights that don't wreak havoc on the Earth's resources. This innovative solar-powered tree is meant to double as a light for remote public areas at night, soaking up the energy it needs during the day.
