The Google PowerMeter API will allow device manufacturers to build home energy monitoring devices that work with Google PowerMeter. Google PowerMeter allows customers to access their power consumption data through a secure, web-based iGoogle gadget. The data can be published immediately (low latency for the consumer) but is currently limited to uploads at 10 minute intervals.
Google is launching this API to help build the ecosystem of innovative developers working towards making energy information more widely available to consumers. The API provides read and write access to its entities and events through RESTful calls and responses are formatted in XML.
Google has a lot of APIs, more than any other company we track. Perhaps as part of adding many APIs, the search giant also has to remove them from time to time. Recently the company has become more liberal in its platform pruning, with at least three separate announcements this year. Most recently Google dropped three more APIs, including the Google Buzz API.
It seems that the API cleaning has not yet ended at Google. Awhile back, Google announced its decision to shut down its popular translation API, a decision that did not go down favourably with the users. Now Google Health API has been given a negative prognosis and Google PowerMeter API will soon run out of juice.
