"A new company is doing more than just monitoring electricity use. It's making tracking your electrical data fun. Steve Reed of San Diego says he signed up for free with OhmConnect. He was eager to see how much his family could cut back on electricity at times when there is a high demand for it in the area. Soon, he got a text prompting him to lower use for an hour — from 5 p.m. to 6 p.m. the next day. The service includes an interactive map of where your electricity is coming from. Curtis Tongue, one of OhmConnect's co-founders, says it makes climate change and pollution less remote and gives people a way to do something purposeful."
