Steps in Developing 100 Percent WWS Roadmaps

So far, this book has examined the main technologies needed for a 100 percent clean, renewable energy and storage system. Virtually all of these technologies exist today, and none is a miracle technology. This chapter focuses on combining the technologies together in countries, states, cities, and towns to provide end-point roadmaps for a transition. Such roadmaps provide targets for meeting energy demand among all energy sectors with 100 percent WWS in the annual average by some year, often 2050, but ideally sooner, such as 2035. Chapter 13 discusses methods of matching power demand continuously (rather than in the annual average) with WWS supply, storage, and demand response. Roadmaps and grid stability analyses are helpful for giving policymakers, utilities, and the public confidence that a transition will not cause grid failures, particularly during extreme weather events.
