PCI's Community Resilience Guide Power from the People was quoted in this article on getting renewables to the 100%.
From the article:
It might help to take a cue from the community power movement. In his book Power from the People, local energy advocate Greg Pahl makes a case for including hydropower, biogas, biomass, liquid biofuels, and geothermal energy to get beyond our dependence on fossil fuels. Which renewable sources are used should depend on what’s most readily available and easy to implement in each community. And supplementing wind and solar with these other renewables can make up for their intermittency -- for example, you can keep a biomass facility going all the time, even when the sun isn’t shining and the wind isn’t blowing.
