The local government encourages homeowners to install solar panels. They promise that doing so will reduce tax bills and mortgages, and that homeowners will receive government support money for the project.

The initial investment is significant, but it should pay off over time. Recently, a new development has emerged: adding batteries to store energy and using intelligent power management makes your home part of a much larger power production system.

Using your own power makes sense if you drive a fully electric vehicle and heat your home with heat pumps.

Investing in batteries and the technology to be autonomous in case of a power outage is quite attractive.
