SQL Server always running

I have a personal computer where I have different instances of SQL server running (developer edition) with both integration services and analysis services (one in tabular and one in multidimensional). I use it for practice and to improve my skills. The start mode in Configuration Manager is "Automatic". So I have two instances each with both SSIS and SSAS. When I am not using SQL Server and e.g. will these services use a lot of resources on my computer by simply running in the background?
