At present, we think of national defense and domestic development as two separate activities. National defense is regarded as the building of arms and armies, and the formation of military coalitions between nations with mutual interests. In truth, genuine national defense is intertwined with social and human needs. The decentralization of energy, food and industrial production not only returns a measure of control to people and their communities, it also makes the nation less vulnerable to disruption and attack. The development and use of renewable resources - combined with conservation - lowers household energy budgets, keeps more of the nation’s wealth from leaking away to mineral-producing nations, creates new industries and jobs, reduces pollution and eliminates most types of environmental damage. At the same time, renewables decrease our dependence on foreign governments so that we are not easily crippled by supply cutoffs or drawn into resource wars. Weaned from imported oil and minerals, we do not require a substantial military presence in far-off corners of the globe. The job of national security becomes much less complicated and expensive.

In a world of this kind, conservation, solar technology, environmental protection, recycling, and small-scale food production become our key defense industries. The national landscape is sprinkled not with nuclear weapons systems, mammoth factories and big, vulnerable power plants, but with low-technology energy systems, a multitude of local power plants using largely renewable fuels, and small facilities producing goods close to their ultimate markets.
Moral, social and economic reasons aside, such a landscape should appeal to military tacticians. It would be nearly impossible to paralyze a country with such a diffuse, flexible fabric…
