Cleantech: Change you can believe in?Worried about layoffs? We'd suggest you embrace the Valley's alternative-energy lifestyle, but electric carmaker Tesla's woes seem to make that a poor bet. Still, SD Forum will be looking at how the next wave of innovation can bring clean energy and water solutions to the developing world at Orrick from 6:30-9 p.m. FountainBlue is also thinking cleantech tonight. Join the likes of Symantec, EnerVault, and Element Partners for a conversation on efficient energy storage at Jones Day from 5:30 p.m-7:30 p.m. More concerned about issues of scale? The MySQL Meetup will be sharing tips on sharding and replications at CBS Interactive while the SF Java Developers will be digging into another enterprise-grade scalability solution at the Marakana Classroom tonight.
