Canadian large-scale hydro projects have an ongoing carbon footprint that is approximately 40% that of electricity generated by burning natural gas. These emissions do not include the carbon footprint of dam construction.
Solar and wind, on the other hand, have a carbon footprint of 4% to 8% of natural gas, even when including the carbon footprint of construction. In other words, solar and wind power are at least five times cleaner than large-scale Canadian hydro. (Ben Gordesky in VT Digger Op Ed)
“Northern biofuel laws and policies have violated the right to food of some of the world’s poorest people by increasing food prices and triggering large-scale land acquisitions that deprive local communities of access to land, water, and food. Biofuels represent the intensification of an industrial model of agricultural production that destroys local ecosystems, contribute to climate change, and exacerbates food insecurity. Ironically, the life cycle greenhouse gas emissions of many biofuels exceed those of the fossil fuels they replace.” From the Environmental Justice Implications of Biofuels, Carmen Gonzales, Seattle University School of Law Digital CommonsUS Corn Ethanol Fuels Food Crisis in Developing Countries by Timothy A.
