I don't read too much into this quote. But it is post-worthy when an Apostle mentions sustainable energy, if only in passing.
Quote from Let Him Do It with Simplicity, General Conference 10/08, L. Tom Perry:
"We have been hearing a lot about fuel and energy—about their high cost and limited supply, our unsafe and unpredictable dependence on their suppliers, and the need for new and sustainable sources of energy. I leave the discussion of these complicated issues to leaders of government and industry. The fuel I want to discuss is spiritual fuel." (italics added)
He certainly wasn't antagonistic towards sustainable energy. Your thoughts?
