According to a CNNMoney.com article, “A Twitter feed for your energy bill?“:
Saving money and averting blackouts
Consumers will almost certainly do their laundry at night and save the $5, if they can watch their energy rates like a stock ticker on an online dashboard, get updates on Twitter, or receive text message on their cell phone when rates are low. With this information, it’s not hard for customers to realize where they can save money and the detail, timeliness, and accessibility of automated information will give consumers more confidence and electric companies fewer resource-intensive customer service calls.
By the summer of 2011, we could all be receiving text messages and IMs when the energy drain of millions of air-conditioners is about to cause a blackout. Then organizations and households can postpone things like scrap metal melting or laundry and dial down their air-conditioning and the blackout could be averted.
