this windmill will be seen perfectly from my kitchen and bedroom window in north burnaby. i'm praying they will not put big flashing red lights on top to prevent planes from hitting hit. and i wonder how this will look from the downtown view cones.
one problem of windmills is that they need wind. if you ever get the chance to visit a wind farm, you will often see a bunch of turbines idle. i wonder if this 20% is when the turbines are running or if the 20% is a yearly average. as well, if you view canada's wind atlas (
http://www.windatlas.ca/en/index.php ) vancouver has some pretty crappy wind. This project would make more sense north of vancouver island. furthermore, energy for 400 (some of the time) homes is barely enough cover a new sub division. so the question begets me, why one? why not 5 or 10 or 250?
from where i sit, this project looks rushed and the politicians are scrambling to look green without doing their research.
eduardo88 mentioned nuclear energy as being viable. Nuclear energy is not very efficient when it comes to powering cities. nuclear plants offer a steady stream of energy and it is very expensive to increase of decrease this flow. cities consume different power levels at different times of the day. of course this could be remedied through diversification, but nuclear is still very expensive to build and insure.
i personally like the idea of "clean" coal. the germans have found a way to pump the CO2 back into the earth. and better yet, its cheap. however, when you say coal, people tend to get a bit uptight so i doubt this will ever happen.
