Trees may light up the world’s streets in the not-too-distant future.
Meeting the need for energy with the ambition of designing aesthetically pleasing innovations has been a major challenge. New types of energy generation are emerging from the sea of clean energy. And an energy-generating tree may change the way our streets are lit up.
What feelings are conjured up within you when you think of “solar trees”?
How power from the sun has become the brightest star in energy production
The renewable energy sector has grown by leaps and bounds over the past decade.
While the wind power market has shown consistent growth, it pales in comparison to the unprecedented growth of solar energy. Data has revealed that the annual growth rate has averaged between 20% and 25% since 2016.
While we can mostly attribute that growth to the Paris Agreement forcing nations to invest in alternative clean energy generation methods, more needs to be done.
The sector hit a record mark in 2024 when it produced 474 TWH in new installed capacity, the largest single growth spurt for any energy resource in history. Naturally, this has led to a significantly large portion of the global community installing rooftop panels to ease the burden of monthly sky-high electricity bills.
Beyond the rooftop: The untapped potential of the sun’s power
Well, a lot, to be frank. Solar panels first came to light commercially in the early 80s, and have since developed into the dominant force in the green energy market.
The world is currently embroiled in the conflict in Iran and the broader Middle East and Red Sea regions, which has placed a stranglehold on the global oil industry. Some nations, including this one, have deployed their strategic petroleum reserves to fill the gap left by the shortage of black gold.
But while all that takes place, the advancement of the sector continues unabated.
Simple hacks to improve the output capacity of home-based solar panels have made relying on rooftop arrays a much simpler task. And one designer has taken the initiative to use power from the sun to brighten our streets and roads.
Solar power now provides many of us with enough juice to disconnect from the national grid.
But one area that has produced significant light pollution in the world is urban lighting. Recent innovations have seen some designers proposing installations that only point downwards, drastically reducing light pollution in major cities.
A green revolution: Your next streetlight might be a “tree”
Thanks to the efforts of Ross Lovegrove, a designer with a close eye on renewable energy, we may have stumbled on the next large-scale application for solar power.
Lovegrove, along with lighting company Artemide and Sharp Solar, created a new type of “tree” that can be used to illuminate our streets.
The purpose of this revolutionary design is to celebrate the convergence of nature, art, and solar technology. Lovegrove created the installations for the Museum für Angewandte Kunst (MAK) in Vienna. Innovative solar energy applications have been emerging as fast as we can think in recent years.
What features do “solar trees” have that make them so special?
The structure consists of 10 “heads” that contain photovoltaic cells that power a set of LED lights that point downwards.
The poles, or “trunks” of the trees, are painted in a vibrant green shade, bringing a sense of color to the grey, urban environments that most of us live in. The base of the structure has several watertight boxes that contain batteries, which can provide the energy needed to light up roadways at night.
Drawing inspiration from nature to design new types of solar power systems can alleviate the concerns over energy insufficiency while bringing a part of Mother Nature to the cities of the world.
