Solar trees!

South Korean researchers are exploring “solar trees” as a way to expand renewable energy without clearing forests for conventional solar farms. Unlike standard ground-mounted photovoltaic systems, solar trees place panels on elevated, branching structures that resemble the shape of a tree. This vertical design uses much less ground space and allows much of the vegetation beneath and around the structures to remain intact. A 2025 study by Dan-Bi Um of the Korea Maritime Institute examined how solar trees could work in a coastal forest in South Korea. Using three-dimensional geospatial simulations and standardized test conditions, the research compared linearly arranged solar trees with conventional fixed solar panels. The simulations found that solar-tree installations could preserve about 99% of existing forest cover while providing comparable, and under the modeled configuration superior, installed power capacity. By contrast, achieving equivalent capacity with conventional panels at the studied site would require removing roughly 98% of the forest cover. The idea matters because forests are more than unused land. They store carbon, support biodiversity, stabilize soil and regulate water. Clearing trees to install renewable-energy infrastructure can therefore create environmental trade-offs, including lost carbon storage and greater erosion risks. However, solar trees are not yet a universal replacement for conventional solar farms. Their taller structures can cost more to build, and the 2025 findings are based largely on modeling rather than widespread commercial deployment. Still, the research suggests that carefully designed solar trees could help land-constrained countries produce clean electricity while keeping valuable forest ecosystems standing.

Light a candle to fight darkness!

HOW CAN I BE HAPPY WHEN THERE IS SO MUCH WRONG IN THE WORLD? A wonderful answer by a Buddhist monk: A man once asked an old Buddhist monk: “How can I allow myself to feel peace or happiness when the world is full of suffering, injustice, pain, and chaos?” The monk looked at him quietly and asked: “If your house was dark, would you refuse to light a candle simply because the whole world is not yet bright?” The man fell silent. “The suffering of the world is real,” the monk continued. “But if you destroy your own peace completely, you may lose the clarity and strength needed to help anyone.” “But isn’t being happy selfish when others are suffering?” the man asked. The monk smiled gently. “Caring about suffering does not require you to suffer every moment. Compassion needs a steady heart. When you are consumed by despair, it becomes harder to respond with wisdom.” Then the monk pointed toward a nearby pond. “When the water is disturbed, it cannot reflect clearly. But when it becomes still, everything becomes easier to see.” He looked back at the man. “The same can happen with the mind. A restless mind may react with fear, anger, or hopelessness. A calmer mind has more space for wisdom, compassion, and meaningful action.” The man lowered his head. “But the world still feels so heavy.” “Yes,” the monk replied. “And that is why your peace matters.” “Do not try to carry the suffering of the entire world in one heart. Be kind where you are. Help where you can. Speak gently. Protect what you can. Reduce suffering in whatever small ways are within your reach.” “A single candle cannot remove all the darkness in the world,” he said, “but it can still brighten the room around it.” In Buddhism, happiness is not about ignoring suffering or pretending that everything is fine. It is about developing enough inner stability to remain compassionate without being completely consumed by the pain you witness. You are allowed to feel joy while caring about the world. You are allowed to rest while others are struggling. And you can protect your peace not to escape responsibility, but to have the strength to meet suffering with greater wisdom and compassion. The monk smiled one final time: “Do not extinguish your own light because the world is dark. Keep it burning. Then use that light to make the small part of the world around you a little brighter.”
