Power Plant generation with dams and some with coal. Now the Wind Turbines.. No nuclear yet... that's all we need... Alberta is big on oil as seen in the photo with its compressor stations to move oil in pipelines... There never is a clean way to move oil...yes there will be spills and on the BC coast will get a big one in time either by pipelines or Tankers. Mans in time will destroy the earth... We are good at that.. Bottom line is the greed of money.... yup money...
