Discussion Questions: Center for Sustainability at Penn State University Tour
- Though David Lettero was living an energy lean existence, he budgeted power for two communication devices. What were they and why were they important to someone living off the grid? Are they equally important to you?
- To provide himself with a variety of greens during the winter, David Lettero nurtured plants in an insulated greenhouse. By December the sun was in the sky for only a short time. What did David have to do before the light levels got too low? How did he ensure that the plants stayed warm enough?
- Based on the perspective that David Lettero expressed just before he rode away on his bicycle, is sustainability a concept that has all the lifestyle solutions worked out? Would you be excited about living off the grid in a similar fashion?
