Siemens has purchased building management firm SureGrid, Green Tech Media reports. The acquisition is a sign of interest in building efficiency startups, which make software that integrates into building management systems created by big companies like Siemens and Honeywell. There’s also an overall trend of conglomeration within the smart grid sector, the article notes, and highlights a few startups as potential acquisition targets: Audra Technologies, Building IQ, Hara, Optimum Energy, Lumenergi and Redwood Systems.
Startup Fenix has created a plug-and-play portable lead-acid battery for developing countries where access to electricity is intermittent. The ReadySet (pictured, left) can power LED lights, cell phones, netbooks and wireless networks, and can last up to three years. The battery also has power generation options that allow it to be connected to a solar panel and bicycle, which users can ride to pump power to the battery. Fenix says its product is geared towards the 1.6 billion people worldwide who live without power, and another 1 billion that deal with regular blackouts. The product also aims to alleviate health problems associated with kerosene lighting, which emits CO2 emissions and causes fires.
Chinese solar module manufacturer Daqo is looking to raise $115 million with a listing of 8 million shares on the New York Stock Exchange, priced between $10.50 and $12.50 each.

Earlier this year, Daqo postponed a January filing seeking to raise $82 million.
