Sure sounds like we need lots of storage then for those windless nights?

> need to come with gigantic storage projects. Was what I responded to. Do you think Texas has anywhere we could store some hydrocarbons? I don't even think that report is optimistic enough, Green Hydrogen production and EVs as demand response and some grid connections will solve the issue cheaper, but I don't want to blow anyones mind, so you've got to meet them halfway with an in-depth accounting of how the vast majority of Texas energy use could be renewable with ease at a low cost.

  Low cost won't cut it. It needs to be cheaper than existing technologies. Citizens don't vote for candidates with a pitch of "what we're going to do is change policy to require significant capital expenditure that is coming out of your pocket". Failing that if you can find a way to line some politicians pockets in the process, that could work.

    It is cheaper. It is apparently hard to sell this to certain political groups, who get their funding from more expensive sources of energy, but the truth has a way of making itself known when money can be earned and/or saved.

      So you think the capex of building new types of energy generation & storage is less than the opex of the existing grid generation centered around fossil fuels, like natural gas?

        Yes, this has been the case for coal and nuclear for a while, and is the case in most places for gas too, even before recent price spikes. The lazard LCOE reports give figures for running costs of existing fully deprecated plants to compare with the cost of new renewables.
