Discussion of national energy policy—to the extent it occurs at all in today's political climate—focuses on spurring power generation from sources that pollute less and building transmission capacity to interconnect that generation with often distant load within the macrogrid.The importance of that discussion is obvious, particularly as it seeks to curb greenhouse gas emissions. The need to interconnect low-emission generation, however, should not divert the attention of energy policymakers from the equally compelling need to move the country toward a power delivery system anchored in microgrids that co-locate generation, load and storage while minimizing energy sprawl and transmission losses.
