I actually planned gasoline on being above $5 a gallon back in 2015 and closer to $6 by 2020.
Electricity is going to go up for several reasons. Mostly greed mixed with poor planning.
I am heavily pro Nuclear as far as power goes. Acutally I am pro supercritical CO2 (sCO2) using nucular as a source.
Rods make heat inside a water tank,
Heat makes water hot,
Steam forms making pressure or in the case of critical sC02 pressure forms. The pressure drives a multi stage turbine then with steam it is mostly expelled.
With sCO2 your dealing with higher pressures in a closed system so a tube(s) inside of the rod tank that is heated. If you take liquid CO2 and heat it up it becomes supercritical before becoming a gas. In that supercritical state it has enough pressure to run a single or dual stage turbine about the size of a shipping container before being cooled back down via river water returning to the liquid state.
A 60x60 building housing 2 generatiors could power a town for the life if the rods. The liquid CO2 is natural, river water natural, and rods good for lets say 30 years. The entire thing could be frankly dang near controlled remotly.
Instead of having one massive nucular plant you have many small ones as common as water towers. This reduces grid transmission issues(power outages).
What do you do with all those pesky rods once they do become spent? Well locally here in Lower Michigan under all that fresh water is a large bowl of rock. Under that bowl is a very large (mostly unknown) salt mine. The mine is very deep and a great source for storage.
So next to your local water treatment plant(massive reserve of water) you will have a sCO2 nuclear power plant. Actually you could have one at your current water treatment plant right now. Outside of the transformer station and several lines coming off the building it could easily be overlooked as just another steel building.
sCO2 power plants are becoming more popular due to the lower initial cost, smaller size, and the fact you just need heat to power them. You could burn stuff and power a sCO2 power plant and if you stopped burning it would naturally cool making it super safe. Although burning trees, trash, waste, or using fuels like coal would be costly and bad. They could be done to power a city using a sCO2 in a safe manner. Nucular is obviously a much cleaner more effective methoud.
The idea of many small things adding up is nothing new.
Going back to that gravity battery. It can be done with water. But it can also be done with weight. Basically think of a elevator with concrete inside. You use wind, solar, or hydro to lift the large weight using a motor(very slowly via gearing) then when those resources are not available you lower that weight (very slowly via gearing) using the motor as a generatior.
Once again many apes strong.
These batteries can be placed in existing structures or in new ones like right next to your local water tower. Just like a water tower is a gravity "water battery" to help during increased demand this gravity "elevatior" battery could also be used during peak demand. The more gravity batteries you have the less the big "pumping station" needs to strain during those peak times. During low peak it can "top off" the gravity batteries. Further more by placing these gravity "elevatior" batteries next to existing structures like watertowers your not making a farm. The structures are spread out leaving less of a footprint. Maintaining, adding, and removing the remote "elevatior" batteries could be a fairly straightforward process unlike a farm structure.
We have lots of options to add capacity without limitation on demand. I dont feel the political and public incentive is there yet.
But hey gas is half what I expected so I obviously don't know what I am rambling on about.
