Residential energy use today accounts for about 20% of U.S. greenhouse gas emissions – though this figure varies widely by region and income level. Certainly, getting more of our energy from renewable resources can help reduce those emissions, but we also need to limit overall energy demand in order to meet the emissions cuts necessary to blunt climate change’s worst effects.

I was talking to my brother, Mark, on the phone last night. We’d been trying to connect all week and finally got the chance. I’m in Arkansas and he’s in Arizona, so the time difference can be a pain.

We just missed each other the day before because he was over with the neighbors across the street.

First the company announced IoT platform called Interact, designed to handle data collected from connected light points, sensors, devices and systems.

Lighting automation has bells and whistles, but a lighting contactor is necessary to switch the actual lighting circuits. Properly selecting lighting contactors can save installation and maintenance costs. What are some of the important considerations in addition to the correct voltage and current?
