Hydro Quebec recently responded to a study commissioned by the Conservation Law Foundation challenging the amount of carbon (CO2) emissions that may be reduced as a result of The Northern Pass offsetting energy produced by the burning of fossil fuels.
From the HQ response:
The facts on hydropower emissions, using a life-cycle analysis approach over a period of 100 years, are actually quite simple. Québec hydropower emissions are:
•similar to those from wind power
•only a quarter of those from photovoltaic solar facilities
•40 times less than those from a gas-fired power plant
•about 100 times less than those from a coal-fired plant.
The Plan’s recommended actions include the importation of hydro power from Quebec; a project like The Northern Pass.
