Low-income households are often the most gravely affected by energy crises, says Jason Edens of the Rural Renewable Energy Alliance, yet they are the least able to afford renewable-energy alternatives.

Send Edens a question of your own by noon PST on Wednesday; we’ll publish his answers to selected questions on Friday.
