There are a lot of the pieces of the puzzle that aren't yet invested in at economies of scale. The problem I've consistently found in these kinds of comparisons is that you are comparing a fully developed infrastructure and economies at scale for oil and gas to the renewable industry, which is still in its infancy and which does not have the full infrastructure elements from start to finish built out. So what these guys consistently try to do is strip out the things that make it apples to oranges to try to get at a fair comparison. It's a tough comparison to do. However, one way to think of it is in terms of inputs:
* Oil and Gas: resource is finite and increasingly scarce, which requires increasing amounts of capital and new technologies to find harder to find deposits
* Solar and Wind: resource is free and unlimited, while the investment required is the upfront capital to build the harvesters and the grid connectors, as well as the storage units to smooth out supply

Imagine if we'd taken the $10 trillion wasted on wars and bank bailouts over the last 16 years and rebuilt our energy grid and done a manhattan project to stand up the renewable energy industry. We'd already be there and enjoying the fruits of that investment. Instead, we have debt and nothing to show for wasting $10 trillion. It's a shame.

" If we've already crossed price parity, then California should be generating the vast majority of its electricity using solar and wind,"

Occasionally; takes time to build out. Utilities are required to be at 33% by 2020. 2 were there in '16.



California hits new big solar peak – 50% of total demand

The US state of California notched up a couple of impressive new solar generation records earlier this week, boosted by a couple of mild and sunny early Spring days.

On Sunday March 4, at around 1pm local time, large scale solar supplied up 49.95 per cent of demand at its pea, beating the state’s previous record of 47.2 per cent that was set in May last year.

The very next day, on March 5, a record peak for solar production was recorded at 10,411MW at 10:18am – up from 9,913MW set last June

>> If we've already crossed price parity, then California should be generating the vast majority of its electricity using solar and wind, and natural gas (which currently supplies almost 50% of our electricity needs) should be only functioning as a supplemental source.<<

Not necessarily. It takes time and grid adjustments to build out the needed renewable infrastructure, but CA seems to be working to that end. Texas, which has more wind energy production than any other state, is fortunate that the grid here, highways and cheap, otherwise worthless desert land were all lined up and in place.
