[1] See this 2011 report on their $293 billion dollar need
[2] See this article about the government of Ontario lowering the rate from $.802/kWh to $.549/kWh in 2012. They lowered it again later.
[4] For a very simple but clear introduction to MEMS gyroscopes, check out this article:
The following from ST Micro provides both an introduction (the first 4 minutes) and starting at 10 minutes, the technical background as to how gyroscopes actually measure the Coriolis effect.
