This is very cool.

The only feedback I would give is that Electricity is a bit misleading. Electricity grids are typically contained networks and not connected to each other between countries or even regions.

For example, in Australia there's the NEM and the WEM. The NEM covers the east coast and the WEM covers the west cost. They're not connected to each other.

Electricity grids also have some interesting properties. For example, every generator on the network must run at the same frequency to keep the grid stable. If any one generator is malfunctioning there's other services that come into play to stabilize the frequency to prevent blackouts.

With the advent of more renewable energy on these grids like wind farms, solar farms and rooftop solar injecting energy into the grid there's new and increasing challenges keeping it stable. Some people have proposed that in the future we might end up with more smaller grids rather than the current large grids we use today.

Interestingly, Bitcoin is starting to play an important part in grid stability as well. Having a constant consumer of energy that can be turned on and off as needed is a great way to keep grids stable. Historically, this has been challenging because most large consumers of energy don't have the ability to turn off and on as easily.

There's a little bit of irony here. All these years the environmentalists have criticized Bitcoin for it's energy usage and it turns it might be the very thing that makes the renewable energy rollout possible.
