With significant short term (batteries) and long term storage, along with dynamic pricing and futures markets can help these markets to run smoothly. Dynamic pricing and Futures Markets will encourage both supply and demand to change so that they match over the short and the long term.

Renewable energy generation is often sporadic. The sun is out during the day, and disappears at night. Out more hours during the summer than the winter. Wind is less predictable. With no batteries, these imbalances can be catastrophic.

EV charging and Heating/Air Conditions systems will increase electricity use significantly for a decade or so, then level off. If we put solar panels everywhere, most of that electricity could be generated close to where it is used.

There are several applications that significantly increasing electricity needs. Blockchain (bitcoin) mining and data centers could grow exponentially for a long time and should be located next to large generation plants. Nuclear, solar, wind, hydroelectric, or other.

The difference between average demand and peak demand could be different by an order of magnitude. Before spending Trillions of dollars on new transmission lines, we should look at increasing generation and storage where the energy is used.
