Four black line icons showing offshore wind, marine energy, and underwater equipment on white

Offshore renewable energy line icons on white background

A clean black line illustration presents four offshore renewable energy concepts arranged in a 2x2 grid on a white background. The top left icon shows a wind turbine standing in water with motion lines and wind marks, while the top right combines a turbine with directional arrows and wave lines. The lower left depicts an underwater pipe or cable section, and the lower right shows a buoy-like marine energy device with a tether below the surface. The simple monochrome style feels technical and infographic ready, with plenty of negative space around each symbol. Strong contrast and minimal detail make the artwork suitable for presentations, sustainability topics, and environmental technology layouts.
