The more heat a process tends to generate, the less efficient it is. Take the old incandescent light bulb. Something like 90 percent of the electrical energy put into is wasted as heat, 10 percent is converted to light. CFLs, by contrast are 65% efficient in producing light, while LEDs are even better at around 80% efficient in their use of electrical energy to make light and not heat.
