Government should find ways to accommodate military, renewable energy. The West, particularly Nevada, would seem to be the perfect place to focus the nation's renewable energy effort given the wide open spaces and abundance of solar, wind and geothermal resources. But one of the difficulties developers have run into is that much of the land is federally owned and energy plants can pose a problem.Although developments are typically planned for sites overseen by the Bureau of Land Management, energy projects can cause problems for another federal landowner ? the military. Wind turbines, for example, can create problems for radar, affecting military training.
