Dear @GovKathyHochul let's not participate in money down the drain.

[Mark Z. Jacobson @mzjacobson]

Money down the drain.

The only two reactors built in the U.S. in the last 30 years took 17 and 18 years, respectively, from planning to operation and cost $16/W, versus $1/W for wind/solar, which take 1-3 years.

Nuclear also poses 5 security risks: weapons proliferation (the cause of the Iran war), meltdown risk (1.5% of all reactors built), waste storage (200,000 y), underground U mining lung cancers, and CO2 (9-37x that of wind per kWh).

Dear @GovKathyHochul why waste money and efforts on dangerous nuclear. It adds cost with no benefit.

[Mark Z. Jacobson @mzjacobson]

As seen from these California data, nuclear, which provides constant power in the U.S., simply adds to the cost with no benefit.

WindWaterSolar already provides >100% of demand for an average, among all days in 2026, of 5.1 hours per day, meaning nuclear provides no additional benefit and just costs more money.

Plus, the rest of the hours, it is replaceable by 3-8x lower-cost/kWh wind, enhanced geothermal, and solar plus batteries. These techs require only 1-3 y from plan-to-operation v 17-18 y for new nuclear.

The "Battolyser" - two machines in one - both a battery and electrolyzer

When the battery is full, additional electricity is used to split water to produce hydrogen.

Useful for avoiding curtailment of excess solar and wind.

Plus, for many grids, both batteries and hydrogen fuel cells are useful for addressing a combination of short- and long-duration storage plus peaking.

[Chris Meder @EVCurveFuturist]

People often ask how long a wind turbine takes to "pay back" its construction CO₂. Surprisingly, including mining, steel, concrete, copper, manufacturing, transport, installation, maintenance & decommissioning, a modern turbine repays its entire carbon debt in 5-12 months.

After that, it can spend another 20-30 years generating electricity while avoiding far more emissions than were created to build it.

Every technology has an upfront footprint. The question isn't whether emissions exist. The question is how quickly they are repaid.

For wind, the carbon mortgage is usually measured in months. The carbon savings are measured in decades.

That's what disruption looks like when physics and economics start pulling in the same direction.

California has the most stable U.S. grid due to its renewables plus batteries

Anti-renewable fans often use California as an example of a state where the growth in solar and wind has increased the risk of electricity-grid blackouts. As it turns out, though, California’s largest grid, CAISO, is the most stable in the U.S., as evidenced by the fact that it had the lowest wholesale electricity prices among U.S. grids during the past year. There has even been no grid blackout since August 2020. Wholesale electricity prices include spot prices, which are the real-time immediate cost of electricity. When spot prices drop, wholesale prices drop. Low spot prices, thus low wholesale prices, mean it is easier to match instantaneous demand with supply on the grid. Because California never had a single period with high wholesale prices during the past year, it had the easiest time matching demand, thus the most stable grid. Why? Although California has grown so much solar and wind since 2023, causing fossil gas use to decline by 61 percent, it has also added more batteries than any other grid region. Batteries respond to a shortage in demand within 20 milliseconds, versus up to 5 minutes for gas. Whereas, California has low wholesale electricity prices, it has high retail prices. But such prices have nothing to do with renewables or batteries. They have to do with utilities passing onto customers the high cost of wildfires caused by transmission-line sparks from 2015 to 2026, undergrounding transmission lines to avoid fires, upgrading an aging transmission system, using some gas and nuclear, the San Bruno and Aliso Canyon gas disasters, and upgrading gas pipes due to San Bruno. Despite California’s high retail electricity prices, Californians pay 23 percent lower electricity bills than Texans because California is the most energy efficient state, using 61 percent less electricity per person than Texas. Lastly, among all 50 states, the more renewables, the lower retail electricity prices. In sum, renewables and batteries stabilize grids and reduce retail electricity prices on top of eliminating health and climate costs of fossil fuels.

Moving the world to clean, renewable energy costs less than world fossil-fuel subsidies

Worldwide subsidies to the fossil-fuel industry exceed the annual cost of transitioning the world to 100% clean, renewable energy for all energy purposes. This means that eliminating fossil-fuel subsidies more than pays for an energy transition. Let’s look at the numbers. Transitioning the world to renewables costs $6.8 trillion dollars per year. According to the International Monetary Fund, fossil-fuel subsidies alone cost $7.4 trillion dollars per year, or 6.4% of world GDP. These subsidies include $730 billion per year in explicit subsidies and $6.7 trillion per year in tax-code benefits, unpaid air pollution damage, unpaid climate damage, and other unpaid environmental and road damage. So, if we want to eliminate the over 7 million air pollution deaths per year from energy, the growing climate damage from energy, and energy insecurity arising from fossil fuels, one sure-fired way is to stop subsidizing the fossil-fuel industry.

Electic cars are among the biggest problems for the grid currently, and yet the Netherlands was among the first to develop the solution: smart charging. When you apply smart charging you can turn electric vehicles from the biggest grid problem to no problem at all.

@MickMechanics Nuclear is down 25% of all hours of the year in the global average.

For the remaining 75% of hours, it never meets demand so always needs backup and is 3-8 times the cost per unit electricity as wind and solar.

Stick to not posting garbage.
