How Does Regenerative Braking Work? Regular brakes waste large amounts of useable energy6 Regenerative Braking systems use the engine to harness this energy6 When slowing down, the engine switches to reverse mode 7 The kinetic energy from the engine is transferred to the battery7 6 Ahn, J.

World-Wide Impact 20% of world's energy use from transportation8 40% of that energy from urban transit8 Can increase the range of a car by over 10% 9 Rising cost of fuel, carbon emissions and desire for extended driving range is leading to a rise in this technology 8 "Print Features."
