Chapter 32: Icons Energy

1. What is the “Icons Energy” Page?

This page lists only the icons from Font Awesome 5 free that represent energy, power, electricity, batteries, charging, lightning, fire, sun, radiation, and related concepts — basically anything to do with energy sources, power supply, or “energy” in a physical/technical sense.

These icons are perfect for:

  • Electric vehicle (EV) charging stations / apps
  • Solar power / renewable energy websites
  • Battery status indicators (phone, laptop, car)
  • Power company / utility provider sites
  • Eco-friendly / green energy blogs
  • “Low Battery” warnings or charging animations
  • Science / physics education pages (lightning, atom, radiation)
  • “Power Up” buttons or energy drink brands
  • Dashboard widgets showing energy consumption

In Font Awesome 5 free, the Energy category is small but very focused (around 8–12 icons, mostly solid fas style). Newer versions (FA6/7) added many more (bolt, plug, plug-circle-bolt, solar-panel, wind, leaf for green energy), but FA5 free already has the most commonly used energy/power symbols that are still everywhere in 2026.

2. Main Free Energy Icons in Font Awesome 5 (From the W3Schools Page)

Here are the key free ones you’ll see listed (solid fas style unless noted; these are the classics from FA5 free Energy category):

  • Bolt (lightning bolt – electricity / power / fast energy) <i class=”fas fa-bolt”></i>
  • Battery Full (full battery icon) <i class=”fas fa-battery-full”></i>
  • Battery 3/4 (75% battery) <i class=”fas fa-battery-three-quarters”></i>
  • Battery 1/2 (50% battery) <i class=”fas fa-battery-half”></i>
  • Battery 1/4 (25% battery) <i class=”fas fa-battery-quarter”></i>
  • Battery Empty (empty / low battery) <i class=”fas fa-battery-empty”></i>
  • Plug (electric plug / power socket) <i class=”fas fa-plug”></i>
  • Charging Station (EV charging station – electric vehicle plug) <i class=”fas fa-charging-station”></i>
  • Radiation (radiation symbol – nuclear / energy hazard) <i class=”fas fa-radiation”></i>
  • Sun (sun with rays – solar energy / power) <i class=”fas fa-sun”></i> (overlaps with Weather)
  • Fire (flame – fire / energy / heat) <i class=”fas fa-fire”></i> (overlaps with Nature)

These are the core free Energy icons — very clean and instantly understood for power, battery, or electricity themes.

4. Teacher Tips for Energy Icons

  • Colors — Green (#28a745 / #4caf50) for full/renewable energy, yellow/orange (#ffc107 / #ff9800) for medium battery/sun, red (#dc3545) for low/empty, blue (#2196f3) for charging/EV.
  • Size — Big sizes (fa-5x, fa-7x) look powerful on banners/buttons; use fa-2x inside text for inline battery %.
  • Animation — Add CSS pulse or shake to low battery icon: @keyframes pulse { 0%, 100% { transform: scale(1); } 50% { transform: scale(1.1); } }
  • Combine categories — Pair with Computers (laptop, desktop), Automotive (car-battery), or Design (bolt for energy in creative work).
  • Accessibility — Add aria-label=”Battery at 75%” or text; never rely on icon color alone for status.
  • Upgrade note — In Font Awesome 6/7, Energy category is much richer (bolt, plug-circle-bolt, solar-panel, wind, leaf, car-bolt) — upgrade for modern EV/solar sites.

Summary – Quick Recap

Font Awesome 5 Energy Icons = W3Schools’ page listing free energy/power icons like bolt ⚡, battery-full/full/empty 🔋, charging-station ⛽, plug 🔌, sun ☀️, radiation ☢️, etc. Perfect for battery indicators, EV charging, solar/renewable energy sites, power companies, low-battery warnings, or any “energy/power supply” theme.

Got it now? Want me to:

  • Build a full “EV Charger Finder” or “Battery Dashboard” demo page with these icons?
  • Show a nice animated low-battery warning?
  • Compare FA5 vs newer versions (way more energy/EV icons)?
  • Or next category like “Icons Files”?

Just tell your teacher — we’re charged up and ready! ⚡🔋☀️🚀
