Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

Lesson by Federico Rosei and Renzo Rosei, directed by Giulia Martinelli.

  2. I honestly can't believe that a TED-Ed video on renewable energy did not mention the discovery or advance in technological ways of harnessing nuclear fusion. Even though nuclear fusion isn't renewable, it's the cleanest possible form of energy. Don't get me wrong, i loved this video and found it very informative. Well done again TED-Ed!

  3. If it's nuclear in nature, then yes……….
    I get that we all want to save the earth, but maybe our focus should broaden. NASA uses nuclear radioactive pellets to power their satellites. The solar sails provide minimal power. Think they're on to something? I'm just sayin
    Waiting for it……. incoming below…….LOL

  4. ADD GEOTHERMAL! YEESH, IT'S THE MAIN 0-EMISSION ONE THAT'S THE MOST ABUNDANT!! COME ONE !! WAKE UP !! AND CARBON-BURNING HAS TO STOP NOW, NOT LATER., OR THE SEA (OUR AIR) IS GONE!! DO YOUR HOME WORK!!!

  5. Perhaps the most efficient geothermal/renewable resources could be used to split H20 on an industrial scale ? Hydrogen fuelled transport with water as a by-product and nil greenhouse gas emissions sounds like a win-win option to me.

  6. Sexual relationship is really a pleasurable give to get relationship with one?s partner. If anything fails within this give and take process, it’s enough to derail the relationship. But any thing can occur and that’s unpredictable. Moreover, able to keep a proper sexual relationship means keeping oneself physically healthy. So any kind of sexual disfunction should be treated with utmost care. One such hazard to health is impotence problems commonly seen in men. Unable to keep a proper and prolonged penile erection contributes to erection dysfunction. This is infact a serious problem for maintaining a proper sexual relationship. So when there arises this kind of problem it?s wise to treat it rather than sitting quiet.

    The choice between the various available treatments involve treatment with a proper medicine. Response to a verbal agent such as Levitra can be quite effective within this context. Studies show that erectile dysfunction is especially on account of insufficient flow of blood towards the penis? veins and not enough stimulation also. Practising oral therapy of Levitra enhances the rate of the circulation of blood that gradually stimulates the penis producing a hard erection, adequate with an intercourse.

    Levitra is a such drug which can be discovered to be effective. Clinically many experts have proved which it even creates patients who suffer from various health conditions like high blood pressure levels, high cholesterol levels or diabetes. A lot of men, who took Levitra for the first time, responded positively for gaining high recovery rate. Besides, it’s been also found who’s can be also taken to medicines utilized to treat other medical conditions.
