Should I Shut Down My Mac When I'm Not Using It?
The short answer is that it's ok to put your Mac to sleep rather than shut it down.
The first benefit of sleep over shut down is the amount of time it takes to resume using your Mac. Usually, waking from sleep takes a matter of seconds while starting up your Mac can take much longer.
Energy savings from shutting down are minimal (if any). When your Mac is asleep, it's in a low power mode. Each time you boot up your Mac it requires a significant amount of energy. It can be very taxing on your hard drive and other components.
