What are the realistic pathways off of fossil fuels and towards a world of abundant clean energy? TED Countdown gathered for its second Dilemma Series — events designed to look at some of the tricky challenges of climate change, where diverging positions have stalled progress — to answer this core question of the climate crisis. Through TED Talks and conversations with experts, activists and leading voices in the space, this film delves into the tension between the necessity to extricate ourselves from fossil fuels, which endanger our collective future, and the equally paramount necessity of a stable and secure supply of energy for everyone. (Featuring, in order of appearance: Catherine Abreu, Tessa Khan, Laurence Tubiana, Hisham Mundol, Hongqiao Liu, Rebekah Shirley, Vijaya Ramachandran, Zoë Knight, Mary Robinson, Lindsay Levin, David Biello, Adair Turner, Jérôme Schmitt, Ramez Naam, Tzeporah Berman, Luisa Neubauer, Emily Grubert and Jade Begay)
Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world. Get involved at

Elon Musk uses natural gas and kerosene for SpaceX launches because it’s feasible and works. Right now!

Lowered out emissions over last 15 years by minimum of 50,000 pounds. Did so incrementally. Remodeling projects on our 72 year old house each have a climate objective. Easier and lower cost to upgrade insulation etc etc. As our appliances fail we replace with more efficient equipment. As vehicles retire added used EVs. Small solar on our garage produces more energy than EVs use. Replacement electric drier uses heat pump and 110v no vent. Ditto heat pump water heater. 20 year old HVAC in process of being replaced by heat pump. At that point we’re 100% electric. Yard tools etc electric. Lowered meat consumption. None of this was overly complicated or too much money. Gotta start somewhere! Most important action??? We stopped talking and started doing. Good luck to all on their journey!

Does anyone really think solar and wind is going to replace the current power plants any time soon? We need an “AND” solution to this. We need to use all green energy sources, including solar, wind, hydroelectric, and nuclear.

Often times, when there are several competing technologies, one turns out to be just best, and is the main tech used everywhere.

The main issue is that there’s no other effective alternative source of energy other then fossil fuels ( and nuclear but no one wants to talk about nuclear anymore). Wind and solar are not efficient enough.

There are several ways to improve the efficiency and reliability of solar-powered hydrogen production:
Improve electrolyzer technology: Electrolyzers are the devices that split water molecules into hydrogen and oxygen gas. Improvements in electrolyzer technology can lead to higher conversion efficiency, longer lifespan, and lower maintenance requirements.
Develop more efficient solar panels: Advances in solar panel technology can increase the efficiency of solar energy conversion and reduce the cost of solar-powered hydrogen production.
Optimize system design: The design of solar-powered hydrogen production systems can be optimized to maximize efficiency, reliability, and safety. This includes optimizing the size and placement of solar panels, selecting the appropriate electrolyzer technology, and ensuring that the system is protected against weather-related damage.
Develop storage technologies: The development of efficient and cost-effective hydrogen storage technologies is crucial for the success of solar-powered hydrogen production. Advances in hydrogen storage technology can increase the amount of hydrogen that can be stored, reduce the cost of storage, and improve the safety of storage.
Improve system monitoring and control: Real-time monitoring and control of solar-powered hydrogen production systems can improve system efficiency, reliability, and safety. This includes monitoring of solar panel output, electrolyzer performance, hydrogen gas production, and storage tank pressure.
Develop new materials: The development of new materials for use in solar panels, electrolyzers, and hydrogen storage systems can lead to higher efficiency, lower cost, and improved reliability.
Overall, a combination of these strategies can help to improve the efficiency and reliability of solar-powered hydrogen production, making it a more practical and sustainable technology for producing hydrogen fuel.

It’s all about globalisation, equalising the class structure across the globe which requires massive transfers of wealth and resources out of Western countries resulting in the impoverishment of their middle, working and lower classes.

Our GDP is nearly 100% correlated with fossil fuels use. Our lives built on fossil fuels. Fertilizer ALONE uses vast quantities of fossil fuels. In our world of 8 billion precious humans with 80 million net new precious humans joining us annually that fertilizer is the difference between life and death for humanity. Nearly all of the nitrogen needed by our bodies is man made. Our precarious situation is more complicated than any one individual can imagine. No number of slogans, videos, propaganda can undo this. We must change the game of civilization built over last 15,000 years. Step one? Spending $7.5 trillion annually on ways to commit atrocities against our neighbors, our enemies dujour must end. Clinging to ancient *culture* as an excuse no longer works. DNA science shows us we’re not only related to each other but to the entire DNA based biosphere. The money and intelligence spent on ridiculous wars is plenty to get moving on greenhouse gases pollution.

If there was a effective or more effective form of energy then fossil fuels the transition would be easy. However the technology on a large scale is not there.

OH YES, the fossil fuel fuel industry will be right in there with the next industry and it will be no better than the currant one. Just like the tobacco industry, jumped into the sugar industry this is what the oil industry will do. Pour money into the land all over the world and grow sugar everywhere it can. Corn, sugar cane and beet. They will turn all that land into fuel. It’ll be no better than we have now. If Brazil can run their cars on sugar 🤪Which they do. (Ethanol) So can other countries.

If anything good comes of fossil fuels, it’ll be weight loss. Sugar will be used for fuel instead. We cant eat it and burn it at the same time. It’s cleaner to burn.

What I would like to know is, why is our electricity charges still going up when so many people have attached their solar panels to the mains. The cost should be going down for all. It’s not coming out of the ground, we should all be winning.

The topic of getting the world off fossil fuels quickly and fairly is a crucial and pressing issue that requires urgent action and attention from individuals, governments, and businesses alike. As we face the looming threat of climate change, it is imperative that we find ways to transition to cleaner, more sustainable sources of energy that do not contribute to greenhouse gas emissions.
This video and the Countdown initiative provide an excellent ways to explore and discuss various strategies and solutions for achieving this transition. From investing in renewable energy technologies and infrastructure to implementing policies that incentivize clean energy adoption, there are many avenues that we can explore.
However, it is also essential to consider the fairness and equity of these solutions, particularly for those communities and individuals who may be disproportionately impacted by the transition away from fossil fuels. It is crucial that we take a holistic approach that considers the social, economic, and environmental implications of our actions and strives to ensure that the transition is just and equitable for all.
Overall, the TED Countdown Dilemma Series is an important and timely initiative that highlights the urgency of the climate crisis and the need for collective action to address it. By engaging in these discussions and exploring innovative solutions, we can work towards a more sustainable and equitable future for all.
