While onshore wind generation has been relatively inexpensive for some time, solar PV and lithium ion battery storage costs have recently shown dramatic reductions. So can Texas, with excellent onshore wind and solar resources, be powered economically entirely by renewables in the 2030-40 time frame? This article brings together the available public material to estimate the cost.
