Save money and energy-saving solar tree lights illuminate the dark night

Techweb12 28 news, today saw a very exaggerated article: solar street lights will illuminate the whole of europe! I'm going to find out what's really going on. This is a major reform, the streets of Europe will soon have a solar tree, which is said to be able to save electricity and energy investment in the street lights.
