International greenhouse-gas emissions hit a brand new excessive, reaching 37.4 billion metric tons in 2024. This 12 months can be on monitor to be the warmest on document, with temperatures by September hitting 1.54 °C (2.77 °F) above preindustrial ranges. International local weather talks fell flat, and disasters from wildfires to hurricanes are being made worse by local weather change.
However amongst all that (very actual) adverse information, there was some good, too: We noticed progress reducing again on probably the most polluting fossil fuels, cheaper and higher applied sciences for combating local weather change, and a steady world effort to deal with the issue. As we close to the top of 2024, let’s take a second to look again on a number of the brilliant spots.
We’re kicking coal to the curb
Considered one of my favourite local weather moments from this 12 months occurred within the UK. The nation has traditionally relied closely on coal as an electrical energy supply—as of 1990, coal met about 65% of its electrical energy demand. However on September 30, 2024, the final coal plant within the nation shut down.
Renewables are stepping in to fill the hole. Wind farms within the UK are on monitor to supply extra electrical energy this 12 months than coal and fuel vegetation collectively.
The second was a symbolic one, and it additionally displays the very actual progress that’s taking place world wide in inching away from this polluting fossil gas. Within the US, coal made up round 50% of the electrical energy provide 4 many years in the past. In 2023, that share was roughly 16%.
We must always see coal use plateau and probably start to fall by the top of the last decade, based on the Worldwide Power Company. Progress must occur quicker, although, and it must occur in international locations like China, the place vitality demand is growing. There’s additionally rising concern about what growing vitality demand from information facilities, together with these used to energy AI, will imply for efforts to close off outdated coal vegetation.
Batteries simply hold getting cheaper
Lithium-ion battery packs are cheaper than ever in 2024, with costs dropping 20% this 12 months to $115 per kilowatt-hour, based on information from BloombergNEF. That’s the largest drop since 2017.
Batteries are a central expertise for addressing local weather change. They energy the electrical autos we’re counting on to assist clear up the transportation sector and play an more and more necessary function for the grid, since they’ll retailer vitality from inconsistently out there renewables like wind and photo voltaic.
Since EVs are nonetheless costlier upfront than their gas-powered counterparts in a lot of the world, cheaper batteries are nice information for efforts to get extra individuals to take the leap to electrical. And it’s arduous to overstate how rapidly battery costs have plummeted. Batteries had been twice as costly in 2017 as they’re at present. Simply 10 years in the past, costs had been six occasions what they’re in 2024.
To be honest, there’s been combined information within the EV world this 12 months—a slowdown in demand development for EVs is definitely one of many elements serving to battery costs hit document lows. EV gross sales are nonetheless rising world wide, however at a slower tempo than they had been in 2023. China is the largest EV market on the planet by far, making up three-quarters of world registrations in 2024 as of October.
Local weather tech continues to be busy and bustling
Wanting again on the vitality and local weather tales we revealed this 12 months, I can’t assist however really feel no less than just a little bit optimistic about what’s coming subsequent.
Some teams need to the pure world to deal with the local weather disaster; this 12 months, I lined an organization working to develop microbes in huge bioreactors to assist complement our meals sources, in addition to researchers who need to vegetation to assist mine the metals we have to battle local weather change. Others hope to tweak biology—my colleague James Temple spoke with Jennifer Doudna in regards to the potential for CRISPR, the gene-editing expertise she pioneered.
Firms are deploying air-conditioning programs that may act like batteries, storing up vitality for when it’s wanted. The US Division of Power is investing in initiatives that purpose to pay attention warmth from the solar and use it to energy the grid or industrial processes. I spoke to a startup seeking to make hydropower expertise that’s safer for fish, and one other constructing magnets utilizing low cost, broadly out there supplies.
And in October we revealed our 2024 record of 15 Local weather Tech Firms to Watch, which featured every part from a startup utilizing AI to detect wildfires to an organization giving dietary supplements to cattle to assist lower emissions from their burps.
Local weather change represents a large problem for the world, and we’re getting into an particularly unsure time. We’ll be overlaying all of it, the nice and the dangerous. Thanks for being right here this 12 months, and I’m trying ahead to bringing you all of the local weather tech information you want in 2025.

One other factor
This 12 months was stuffed with some thrilling moments in expertise, however there have been additionally some failures. Listed here are a couple of of the worst expertise flops of 2024. Test it out to see why voluntary carbon markets made the record and study all about AI slop.
And yet one more
You’ve virtually definitely heard that vitality demand from AI is large, and solely anticipated to blow up within the coming years. A brand new preprint research aimed to quantify simply how dangerous issues are, and the researchers discovered that information facilities accounted for over 4% of electrical energy consumption within the US between September 2023 and August 2024. And the carbon depth of the facility that’s used is almost 50% increased than the nationwide common.
Get all the small print within the newest story from my colleague James O’Donnell.
