If china and EU Will take over the world then rubles and dollars Will be Like simbawe dollars nobody really don't need it and oil countries economy Will fall down a lot.
Green energy, not as easy as you say and imagine, is used all over the world, even though some countries have abundant natural resources, apart from Green Energy requiring a large economy, other factors must also be considered.
Example:
Overall Green Energy has technical weaknesses for Green Energy and also other factors, such as required storage such as batteries so that they are not wasted, weather factors, because Green Energy is taken from various natural resources, plants, water and so on, not to mention the capacity of Green Energy users such as companies that require large amounts of electricity, I'm sure Green Energy can't handle all that.
China & EU can't shake the world, if you talk about Energy, oil and economy, the world has what China & EU don't have, they can't rule the world.
This is true, although people aim to create and use green energy, it also has many limitations and I believe it will never replace the current energy source. My country has built a lot of large windmills to generate wind energy, but in recent years they have found that blocking the direction of the wind creates a lot of weather instability that affects crops, is expensive to maintain...and they started dismantling it all.
