A clean energy future is within reach.

We can have a world powered by cheap, reliable and abundant clean energy.

But to unlock that future, we need to build far more high voltage transmission lines and update the entire energy grid.

Now most electricity doesn't travel very far because it used to be that power plants always placed close to where the demand for electricity was.

You could put a coal plant or a natural gas plant near to the big cities.

But clean energy now is going to be much further away.

It'll be where there's deserts with the sun, where there's wind quarters, and that means the distances will get far far greater.

And so to ensure that every household has this clean reliable power, we need transmission and a lot of transmission.

By the 2030s, we need to build so many new lines that they would reach to the moon if they were strung together and by 2050 only to more than double the size of the grid while eplacing most of the existing wires.

Building this node transmission is not going to be easy.
