Energy points aren't supposed to show how much hard work and time you put into completing skills, completing programming challenges, earning badges, and watching videos. It's a marketing business method to attract people to join KA, it's like [http://en.m.wikipedia.org/wiki/Virtual_good virtual stuffs) in game.

For me, earning Tesla is like traveling 250 kilometers in 1 day. There's no rule that you need to walk but many users are still constantly believed in "spirit" to earn virtual stuffs in marketing place.

Just my opinions :1
