Elon Musk's SolarCity is completing the construction of its "Buffalo Billion" Gigafactory for photovoltaic (PV) cells near the Niagara River in Buffalo, New York. It will soon put 500 New Yorkers to work inside the 1.2 million-square-foot facility with another 700 nearby, ramping up to nearly 3,000 over the next few years.

The production of some 10,000 solar panels per day will put thousands of New Yorkers to work doing the installations. The panels will produce electricity cheaper, cleaner, more safely and more reliably than any fossil or nuclear source of power, including fracked gas, thus fueling a bright industrial future for the state.

With a little common sense from the governor, upstate New York could have many more of these massive factories, create many thousands of good, stable, high-paying jobs and solve its energy problems along the way.

All he has to do is shift over the absurd, wrong-headed $7.6 billion hand-out he now wants to give the Illinois-based Exelon Corporation for continuing to run four extremely old and dangerous nuclear reactors.

Those four reactors employ a total of about 2,100 people. They came online in 1969, 1970, 1975 and 1988 respectively. Aside from being dangerously decrepit, they run the risk of early shutdown because of general mechanical deterioration, rising maintenance costs, a shortage of replacement parts and the likelihood of major component failures.

At some point all operating reactors will also face escalated safety standards certain to result from the next Fukushima-like disaster, an ever-more likely reality as the global nuke fleet ages and deteriorates. Because the nuclear industry is failing throughout the U.S. and Europe, there is an ever-narrowing pool of workers qualified to keep the plants going. Because the electricity they produce is so expensive, they will drain a huge pool of resources from a state-wide economy in desperate need of industrial rebirth.

By contrast, SolarCity's solar panel plant will be productive for decades. It's called the Gigafactory because it will produce a gigawatt's (1 million kilowatts) worth of solar panels every year, about the same as a nuclear reactor. (Depending on climate and sunlight, PV capacity produces electricity equivalent from about a half to a third of the capacity from an atomic reactor, assuming the reactor doesn't blow up, melt down or shut for other reasons).

The cells produced at "Buffalo Billion" will spread throughout New York and the nation, revolutionizing our energy system. The energy those cells will produce will create far more jobs than subsidized nukes and would emit no greenhouse gases. The nukes they'd replace currently emit billions of gallons of hot wastewater annually, a major contributor to climate chaos.

Should the money Gov. Cuomo has earmarked for those old Exelon nukes be shifted to solar, New York's economy would be revolutionized.

The template for such a plan has already been established by Pacific Gas & Electric at California's last two reactors. Surrounded by earthquake faults at an oceanfront site nine miles west of San Luis Obispo, the Diablo Canyon nukes are being phased out in an agreement between the state, the utility, environmental, labor and local government groups.

Pacific Gas & Electric has admitted that the power Diablo produces can be replaced with 100 percent renewables. The company has also agreed to retain the plant's 1,200 workers through the phase-out and retrain them for jobs in the renewables industry at when the plant shuts down. Surrounding communities will also be compensated for lost tax revenues.

Gov. Cuomo should take heed. The $7.6 billion he's earmarked for these four upstate nukes comes with a price tag of $3.64 million per retained job. But in the solar/efficiency field, the state is producing jobs manufacturing clean energy technology with far better long-term prospects for just $148,000 per job.
