Germany once paid several times the retail rate for solar but has reduced the rates drastically while actual installation of solar has grown exponentially at the same time due to reduced cost of solar installations.
Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic ...
