  • The United States may find a path forward by pursuing market conditions like Australia, where over 40% of homes in some regions have rooftop solar. Soft costs are far lower in the nation, and average residential solar installation cost was $0.89 per W, more than $2.00 per W cheaper than both Canada and the United States.

    That path requires oligarchist monopoly utilities to have less influence on oligarchist political parties. Biden’s approach of creating a new green energy manufacturing oligarchy protection doesn’t help with low prices that could be achieved if main utility monopoly obstruction to home solar were removed. FF Oligarchy assists utility monopolies in their lobbying for centralized power production. It is not within US political corruption overton window to help citizens escape extortion.







  • H2 makes the best long term electrical storage, because not only is it more efficient than other cheap alternatives, it can be even more efficient with heat use, and it is economically transportable/exportable and so is not capped by utilization/capacity constraints.

    heat storage is extremely useful for complementing winter solar in low winter sun places. Including at small scale. Hydronic floor heating is most efficient use of heat. Heat pumps can very efficiently gain 30C of temperature gain. Sand and construction waste box with water pipes, and heat resistors, flowing through it, can store heat well above 100C that water doesn’t ineffienctly. 2000 liters of just water is sufficient in most locations with a fireplace or EV backup, but sand/dirt/gypsum of 500L to 1000L significantly boosts resilence and heat capacity.



  • Mines like datacenters can be in remote low land value areas that have a lot of room for solar, which without grid connections is even cheaper than grid connected energy, and cheaper power than transporting fuel. Surrounding land, certainly not usable for civilization. Most uranium mines in the world have a proper exclusion zone that allows more solar energy than the energy value of the uranium inside the mine.

    After mine’s life, power availability means a cleaned up side does have civilization/land value. It also makes it attractive for eventual grid connection to rest of continent, or just “microgrid” short transmission to touristier locations. Solar development of a mining area not only offers cheapest mining operations, it creates future land value appreciation, and power supply revenues. Both significantly improving economics of a mining project.
