Renewable Energy Isn’t Perfect, But It’s Far Better Than Fossil Fuels – by David Suzuki (Huffington Post – November 29, 2017)

In their efforts to discredit renewable energy and support continued fossil fuel burning, many anti-environmentalists have circulated a dual image purporting to compare a lithium mine with an oilsands operation. It illustrates the level of dishonesty to which some will stoop to keep us on our current polluting, climate-disrupting path (although in some cases it could be ignorance.)

The image is a poor attempt to prove that lithium batteries and renewable energy are worse for the environment than energy from oilsands bitumen. The first problem is that the “lithium mine” is actually BHP Billiton’s Escondida copper mine in Chile (the world’s largest.)

The bottom image is of an Alberta oilsands operation, but it’s an in situ underground facility and doesn’t represent the enormous open-pit mining operations used to extract most bitumen.

Lithium is used in batteries for electric cars, cellphones, computers and other electric devices, as well as power-grid storage systems, because it’s light and highly conductive. Most lithium isn’t mined. More than 95 per cent comes from pumping underground brine into pans, allowing the liquid to evaporate, and separating out the lithium using electrolysis.

Any real comparison between oilsands and lithium batteries shows that oilsands products, from extracting and processing to transporting and burning, are by far the most destructive. Extraction and production destroy habitat, pollute air, land and water, and produce greenhouse gas emissions. Burning the fuels causes toxic pollution and wreaks havoc with Earth’s climate.
