About the Energy black filled icon
One sharp lightning bolt is drawn as a zigzag wedge, wide at the top and tapering to a point at the bottom with a single hard kink at the middle. It is the universal shorthand for electric power, high voltage, speed and stored charge. Use it for battery and fast-charge indicators, utility and electricity bills, renewable power dashboards, performance or boost modes and outage alerts.
The bolt leans slightly so the silhouette stays dynamic, and the thick upper section keeps it visible at very small sizes. It pairs with battery, plug, solar panel and leaf icons in an energy or sustainability set. It works well as a badge overlay on another icon to mark a powered state.
This is the solid black filled version of the energy icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
