Answer #1

If we choose electric high speed trains as our energy efficient mode of transportation, and making an assumption that all of its coaches are full and trains manage to achieve outstanding efficiency without travelling slowly, and without having a low weight per person. Trains make up for their high speed and have small frontal area per person then the average energy efficiency 3 kWh per 100 person-km which is far far lesser than an individual car.

1. In an effort to reduce energy costs, a major university has installed more efficient lights as well as automatic sensors that turn the lights off when no movement is present in a room. Historically, the cost of lighting an average classroom for 1 week has been $265. To determine whether the changes have signficantly reduced costs, the university takes a sample of 50 classrooms. They find that the average cost for 1 week is $247 with a standard deviation...
