A bit of truth for Calizuela environmentalists

The cost of supporting the production of renewable energy seems eye-watering. This column argues, however, that the alternative of a future energy system lacking the benefits of low-cost zero-carbon technologies is even more costly. While most renewable technologies are not yet competitive on cost with mature carbon-intensive technologies, support for renewables can be justified by learning spillovers.

The author points out that current renewable technology generally releases more CO2 than the equivalent fossil fuel solution.  They get that result by counting all the costs, not have the costs like the Cal environmentalists do.  Hence, they recommend learning a bit more about it.
