The February 2021 energy crisis in Texas was yet another stark reminder of just how broken our national power grid is and how difficult the energy transition will be. The shift to renewable energy will come with unintended consequences such as price spikes from less mining and drilling, or times when the wind doesn''t blow.

At large power amounts, the engineering is more complex and there''s a lot of directional components there. As we increase the amount of distributed power, whether that distributed power is from PV, solar, biomass, whatever it is, the complexities in how the power flows in the grid increases. It becomes much more challenging to manage this in
