Unreliables

      Due to their intermittency and their diluteness, unreliables don't replace reliable power plants, they  are simply an add on to an already existing reliable energy source. This is the reason for the massive electricity prices for countries with high unreliable energy use. . They simply cannot operate without having a reliable energy source backing them up. They are also  a wasted opportunity cost. The monies spent on unreliables takes away from the monies on invigorating the reliable power systems. We have seen this in California, with the failure to upkeep their powerlines and in TX where they have less robust reliable systems due to monies being spent on the unreliables.

Texas Electricity Crisis By Alex Epstein

Quick Summary For the last decade+ policy in TX and in the US has been focused on mandating or subsidizing as much wind and solar as possible. TX has bragged about being the biggest wind generator in the US. 1 The TX focus on wind has come above all at the expense of coal, which has the resiliency advantage (along with nuclear) of being able to store large quantities of fuel onsite; gas mostly requires "just in time" delivery from pipelines. “In 2009, coal-fired plants generated nearly 37 percent of the state’s electricity while wind provided about 6 percent. Since then, three Texas coal-fired plants have closed...In the same period, our energy consumption rose by 20 percent.” 2 Because intermittent wind and solar can always go near zero--as we saw recently in TX--they don't replace the cost of reliable power plants, they add to the cost of reliable power plants. This is why the more wind and solar grids use, the higher their electricity prices. To lessen the price increa...
