I agree that Congress should bring the Green New Deal resolution to a vote. In that way, the voting public can identify all of the lunatics in our government that support this resolution, as the proposal would place America back in the Stone Ages. The notion that solar and wind power can supply all of America’s electrical supply needs is laughable!

Let’s analyze just one element in this “deal”:

The electrical transmission grid must have uninterrupted capacity with a significant reserve margin ~25 percent for stability in the event of power interruptions (storm damage, system faults). Electrical load cannot be controlled without power interruptions. That means that base-loaded generators (fossil and nuclear fueled) and emergency peaking units (natural gas) are essential to prevent blackouts.

On a calm, overcast day or nighttime, solar panels with current technology and wind generators are ineffective. During these periods, large, fossil-fueled units, nuclear units and “peakers” are necessary to provide reliability. Also, the capital cost of solar and wind generation is relatively expensive. The average cost for a typical six kilowatt solar system (after federal investment tax credit of 30 percent of the cost) is ~ $13,000, with an average service life of 25 years, based on EnergySage Solar data.

The bottom line is an energy mix with a combination of base-loaded and renewable power supplies is a rational approach. As technology advances, further efficiencies and improvements may shift the mix. Nuclear power plants could have resurgence with the concern for air pollution. The new designs are smaller, intrinsically-safe with passive safety systems not relying on off-site power.
