Rubbish.  The entire surface area of the reservoir is 4,000 Ha, or 40 square kilometres, (20 Km  x 2 Km.) That's roughly double the surface area of the river at present. The area to be flooded represents 0.4% of Ag land in the Peace River district and 0.2% of Ag land in BC.  If that will feed 1 million, the balance of Peace River Ag land can feed almost 140 million Canadians. 

Alternative energy sources? A  windmill has a 20 year lifespan. A dam's electrical generation capacity is approximately 100 years.  The Paris accord requires CO2 cuts of 30% by 2030, the transportation sector which contributes 27% of CO at present, must be electrified. The claim that we can rely on the Columbia River (USA) dam's capacity is foolish. When Trump says America First, it means everyone else last. The only energy security we can count on is our domestic supply.

Finally, blowing off about $5 billion to mothball a $9  or $10 billion project is astoundingly stupid.
