Electricity - Unintended Consequences

Renewable electrical generation (windmills and solar panels) is not sufficient nor reliable enough to support the demand for electricity. The wind does not always blow.  The sun does not always shine.  Typical  of California the demand is greater than the supply.  This results in rolling brown-outs and black-outs amid pleas from the ruling elitists for everyone (but them) to reduce usage by dimming lights and turning up the air conditioners.  So, what is the unintended consequences?  As the California model becomes deeper and more widespread people will begin to buy and install home generators to take-up the slack.  So, what’s wrong with that?  Those little home generators require diesel (fossil fuel) to run the motor required to rotate the dynamo that generates the electricity.  So, thousands of these units belching out diesel fumes will negate any climate change advancement for pure clean air.
