The news: Powering the world with renewable energy will take a lot of raw materials. The good news is, when it comes to aluminum, steel, and rare-earth metals, there’s plenty to go around, according to a new analysis.
Greater pay off: Although emissions are an unavoidable side effect of extracting the materials, over the next 30 years they add up to less than a year’s worth of global emissions from fossil fuels. Experts are confident the up-front emissions cost will be more than offset by savings from clean energy technologies replacing fossil fuels.
But there’s a catch: While we technically have enough of the materials we need to build renewable energy infrastructure, actually mining and processing them can be a challenge. If we don’t do it responsibly, getting those materials into usable form could lead to environmental harm or human rights violations. Read the full story.
