to build a battery electric vehicles with zero emissions you need renewable energy to do that. it does not make sense to build batteries, electric batteries with fossil fuel generated electricity so particularly in the case of spain with 50% of energy sourced from renewable energy and the potential that becoming more. you can see behind me the sun is shining. the sun shines through the day so we have a huge potential of renewable energy and i think that plays an important role, a decisive role in the case of spain. what is the tipping point? when are we more likely to be in an electric vehicle than one fuelled by fossil fuels? that will depend a lot on the country, i think. if we look in the north of europe, it is already very advanced. the average across all of europe is 20% of sales are electric vehicles, germany is slightly higher, 25%, and scandinavian countries are even higher. the uk also are 20% or 25%.
