ommunity has a nighttime energy demand of 50 megawatts but a peak daytime demand of 75 megawatts. It has the chance to build a 90-megawatt coal-fired plant that could easily supply all of its energy uses even at peak daytime demand. Should it necessarily proceed? Could there be lower-cost options? Explain.

Resource consumption per person in the United States is either flat or falling, depending on the resource. Yet living standards are rising due to improvements in technology that allow more output to be produced for every unit of input used in production. What does this say about the likelihood of our running out of resources? Could we possibly maintain or improve our living standards even if the population were expected to rise in the future rather than fall?
