Regenerative braking and other forms of energy capture are becoming more popular and increasingly effective. What started as a way of increasing the range of electric or hybrid vehicles is now being applied to everything from green buildings to industrial robots.
The automotive industry is still the main driver of this technology. The idea that braking can generate energy has been around for more than a century. It is standard in almost all electric and hybrid cars today, and as the volume of electronic content in vehicles continues to grow, it is finding applications in all types of vehicles. It also is evolving, becoming more sophisticated and more efficient.
