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.

  1. No mention of High Voltage DC for long range transport?
    artificial created Diesel is also a thing
    carbon based fuel is safer than lithium, li-batteries tend to go up in flames on its own and fires can not be extinguished so easily.

  2. There already are farms, that produce algae and from that bio-fuel. So we just need to expand on that concept.
    There is no need to convert electrical energy to chemical, if one can produce biological and from that chemical directly.

  3. We already have the means to power the world and we have had to the means to do so for a long time, nikola tesla conceived the idea of a global semi-wireless electricity network using the electricity in the atmosphere.

    We have 100% renewable energy already, it's just that porkies cant sell it so we'll never get such innovations.

  4. Also one thing can’t we just transmit energy with radiations and what’s with superconductor can’t you just let out 6 or other percent and still have enough now also third thing cars and airplane can easily use highly ionic compounds like ceaseium chloride for solar panel instead of caesium with some positive catalyst to support action
