If you use a pressure cooker, it takes less energy apparently. The more energy efficient method would be to pre-soak them for a long time, then cook on a pressure cooker (on low heat, hot enough for the pressure cooker to keep at full pressure though...but it doesn't take much heat to do that). I have a Hawkins classic pressure cooker. Apparently the Hawkins Futura line is even more efficient.
