Quebec power and internet pricing is really competitive. For residential services I pay $0.06/kw + $80/mo for 1Gbps fiber with 1ms ping to 8.8.8.8 (USD).
As a result, I run a power-hungry Dell r610 with 24 cores and 48GB of ram with 20+ services on it for many different aspects of my company. All the critical stuff runs on DigitalOcean / Vultr, but the 20+ non-critical services like demo apps, CI/CD, cron workers, archiving, etc. run for <$200/yr in my closet.
