Personally, I started buying renewable energy credits (RECs) through Arcadia Power, a third party, to offset my apartment's power usage. There is a likelihood I will move to San Diego for grad school in the Fall, which is why I didn't do something more involved, such as subcribe to a community solar project. That being said, it looks like the energy utility in San Diego allows people to subcribe specifically to 100 percent renewables, so I will be in good shape if I go over there.
Other than that, I have been trying to ride my bike more to the grocery store. My panniers can carry a lot, but I still probably need to make two trips in a given week to feed 2 people (yay exercise!).
