Clean energy icon set with solar panel, wind turbine, battery, and plug

A simple black line icon set sits on a white background, arranged as four separate symbols in a balanced grid. The set includes a solar panel, a wind turbine, a battery with a lightning bolt, and a power plug combined with a leaf. Crisp outlines and generous white space give the graphic a clean, modern look suited to sustainability, renewable energy, and eco technology themes. The minimal style makes each icon easy to read at a glance, whether used in presentations, infographics, or website interfaces. Strong contrast between the black strokes and plain background keeps the composition clear and versatile. Nothing else appears in the frame, so the image functions well as a neutral design asset for energy-related content.
