In certain embodiments, an energy conservation system can be configured to deliver energy to the energy consuming device for a period, followed by a period where energy delivery is dampened and/or cut. By cycling the delivery of energy in this fashion, the energy conservation can achieve a pulsed efficiency. ## Claims ### Claim 1 A computer-implemented method of conserving energy used by a device, the computer-implemented method comprising: receiving, by a computer system, a first function comprising a first energy output of a device over a time period;
