How does the environmental impact of mining for clean energy metals compare to mining for coal, oil and gas?
Mining, whether for fossil fuels or metals used in clean energy technologies, has serious environmental impacts, and it’s hard to make apples-to-apples comparisons—except in terms of their impact on climate change, where clean energy mining is clearly better.
If cities require new buildings to use 100% electric heat, will that raise or lower their greenhouse gas emissions?
Electric heating can cause a short-term rise in emissions in areas that get their electricity from fossil fuels. But without electric heat, we can’t get greenhouse gas emissions to zero.
Do we have the technology to go carbon neutral today?
We still need new breakthroughs to decarbonize many parts of our modern economy, especially if we don’t want to drive up the price of energy and goods. But we can make real progress with today’s technology, and invest in good ideas for the next generation of low-carbon solutions.
