Two groups this week underscored the need for consumer access to real-time dynamic electricity pricing to reduce greenhouse gas emissions and save money on their bills. On Monday, the Association of Home Appliance Manufacturers (AHAM) released a white paper strongly advocating that “residential electricity prices must be based on time of use” to fully enable smart grid technology. Yesterday, multiple high-tech companies and advocacy groups issued a statement at the United Nations-sponsored climate change negotiations in Copenhagen (COP15) urging world governments to ensure consumers see real-time energy use data to improve energy efficiency and cut greenhouse gas emissions.
