Fifteen years ago, Uruguay was experiencing an energy crisis brought on by its reliance on fossil fuels; today, the nation produces 98 percent of its electricity from renewable sources (and even exports extra energy to neighboring countries). How did they turn things around so quickly? Uruguay’s former secretary of energy, Ramón Méndez Galain, explains how they pulled off this unprecedented shift — and shares how any other country can do the same.

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

    How we can expand the electrical grid and also protect it. I just went ev with my car.

    TED I’m so disappointed in how you treated Coleman Hughes, caving in to appease the complainants 😢.

    I find extremely embarrassing that the UK is kicking the can down the road on making our energy cleaner. They the elites used the excuses of how things will make the uk bankrupt and expensive. Yet the tory government has failed to embrace the opportunities of Green energy, jobs and tech./science.

    Uk should be leading, like every other nation that is trying really hard to move away from fossil fuels. But instead the british elite has fallen right wing clown ideology.

      That is why they have multiple types of energy source. Having a good portfolio will help the transition.

    • Soya Suki

      October 2, 2023 at 11:03 am

      Did you even watch the video? Addressing exactly that is a mayor portion of the talk. Starting around 5:00

    • Anandkuno

      October 2, 2023 at 11:14 am

      @Soya Sukihi, I did watch it again, and may I know what did I say that is wrong? Having multiple energy sources is what allowed the country to not rely on the fossil fuel for electricity.

      Of course the country still need fossil fuel for transportation.

    • P. B. Foote

      October 2, 2023 at 8:27 pm

      This is by far the most commonly asked question in the renewable resource vs. fossil fuel argument. It’s also the most ignorant.
      But, for your edification the short answer is . . . drum roll please . . . batteries. What do think powers your car’s lights and fans when the motor’s not running? What powers the starter motor when you turn the key to ‘start’? Hint: It’s not magic.
      BTW: If you’re still invested in fossil fuels: Ha-ha!

      Could it be an anti-misinformation statement, as in opposition to Alex Jones’ “Infowars’?

    This talk shows what can happen when there is no political influence from fossil fuel vested interests. Since Uruguay has no fossil fuels, they have no fossil fuel industry lobbying the government. This suggests that in the US a critical ingredient for success is to nullify the influence of fossil fuel vested interest.

    How? Go to the dark side and use the same PR tools and propaganda tools against the fossil fuel industry that they have been using against us.

    If it moves on its own, or is hot, it can be converted to usable energy. Water flowing, waves, air currents, sun. Everything. It’s just finding the right method and source.

  13. Sirus Laia

    I wish the UK where I live had done more to explore the renewable possibilities as Uruguay has done. But with Sunak at the helm, I don’t have any hope.

      @ICE SKULL gaming Solar still works even during overcast days btw, just like how plants manage, but it’s lower efficiency of course. Also hydro works.

  14. djayjp

    October 2, 2023 at 1:09 pm

    4:00 Wtf is a “traditional hydrothermal power mix”…?

    Also burning that biomass releases tons of CO2.

    • dryzalizer

      October 2, 2023 at 5:07 pm

      I think he misspoke and meant to say a traditional hydropower and fossil fuel mix.

      I agree with your second point, if they’re doing basic biomass burning to generate power that’s not carbon-friendly at all. If they can capture the CO2 that would be great, but he didn’t say a word about it.

      Overall though, this is a big step in the right direction and in particular the need for political parties to come together to get it done is probably the biggest hurdle in many countries at this point.

    • P. B. Foote

      October 2, 2023 at 7:47 pm

      98% renewables and that’s your takeaway?
      If you came expecting perfection, you came to the wrong place.

    • djayjp

      October 2, 2023 at 9:07 pm

      @P. B. Foote Idk I live in British Columbia where we’re already like 95% renewables. If he was being unbiased he would’ve stated the carbon released from burning biomass, but just presented it as though it’s perfectly fine. Btw you’re confusing burning biomass % vs fossil fuels–the latter was 2% and sometimes 7% annually in dry years. Point being that burning biomass shouldn’t be considered green or part of the solution.

    • P. B. Foote

      I’d rather not live near a nuclear power plant, let alone work in one. But I have no problem living near a factory that builds wind generators and/or solar panels, especially if it offers good, high paying jobs to me and my neighbors.
      BTW: How much does it cost to decommission a nuclear power plant compared to, oh, say, anything else?

    I love to death how Dr. Galain asserts that there is a fallback/insurance of fossil fuels, but that’s OK; it doesn’t invalidate the system.

    • Sag Norm

      October 3, 2023 at 9:10 am

      It does invalidate it. Its nonsense. First off, there is nothing good about “burning sustainable bio mass”. Second, why is there no nuclear energy? Nuclear energy is the inevitable future.

      The fossil fuel fallback is just pure corruption. After a few elections, the “fallback” will become the main source lol. And why didn’t they use modern nuclear for the fallback?

      And your fears of nuclear disaster is nonsense. Even with the 70 year old technology of the 1950s, it was very safe with a low probability of failure. If they ever decide to make modern 21st century nuclear reactors, there would be 0 risk.

  35. Fred Bear

    October 3, 2023 at 6:42 pm

    Yeh, but they have regular blacks as the power is not consistent. About 3 million people in Uruguay experienced the blackout. The blackout forced some businesses to close and interrupted public transit; it also led to some water shortages, as some water systems were powered with electricity. “It looked like a zombie city,” a taxi driver in Buenos Aires told the New York Times.17 June 2019.
    This guy is absolutely full of it. Imagine doing this to a big company. Uruguay is less than 3.5 million people.These people are mad and anyone who thinks they can do this in the UK, USA or any industrialised country.

    • Bernard George

      October 6, 2023 at 5:00 am

      Sorry no. The US is not a tiny country that can rely on imports of dirty power when renewables are not producing. Nor can it have hydro power to the same extent as Uruguay. You have been taken in by slick marketing.

    • DrinkinItIn

      October 7, 2023 at 3:54 pm

      @Bernard George Appreciate your reply but I disagree with your assessment. My point was that nobody in the US works together. Who knows what could be accomplished if everyone stopped fighting and disagreeing. It is a pollyanna type thought because we are so far gone but maybe one day we can make some progress.

  39. We hit extracellular idiom bite

    October 4, 2023 at 6:38 pm

    This is rather misleading. All cars and buses and trucks are actually mainly powered by fossil fuels, thus emitting colossal amounts of green house gases even in Uruguay. So don’t trust too much in this sweet reality {about electricity 🔌 generation being not generating a lot of CO2 in uruguay} as a reality which will really help achieve the goal of Paris agreements. It will not. ❤🎉🎉 we need to cut our GHG emissions and this will require sobriety/slashing economic growth.

  41. Bernard George

    October 6, 2023 at 4:52 am

    Terribly misleading.
    First, Uruguay is not self-reliant. It imports and exports huge amounts of electricity (sometimes importing half its consumption) to cope with the intermittency of renewables. It is a tiny country (3.5m people) dependent on dirty power from its neighbours.
    Second, when he says wind and solar power are equal to demand, he means CAPACITY. The power produced by wind and solar averages at about 10% of capacity for solar and 20% for wind.
    Third, it has massive hydro power, which is not possible at the same scale for most countries.
    Lovely feel-good stuff, so long as you do not think about it.
