"Still No Miracles Needed" is out

Describes how to solve the climate crisis, and at the same time eliminate air pollution and safely secure energy supplies for all - without using miracle technologies.

“We have 97% of the technologies we need to solve the climate, air pollution, energy and security problems the world faces.”

@bertiehb.bsky.social speaks to Mark Z. Jacobson about his new book, “Still No Miracles Needed,” published by Cambridge University Press

Yes.

New paper

Enhanced geothermal obviates need for nuclear & can be used for datacenters

Cost of 100% WWS w or w/o baseload EGS are similar->no baseload needed

100% WWS w or w/o EGS reduces cost 60% v BAU

Low EGS land use helps small countries move to 100% WWS

Why new nuclear is obsolete and useless in New York or elsewhere, regardless of how much money is poured into it..

Do Cheap Batteries Today Eliminate the Barrier to Replacing Fossil Fuels for Electricity?

Yes

E.g., the 11.2 GW/44.7 GWh of battery storage on California's main grid is equivalent to only 0.2 c/kWh-grid-electricity-consumed

In this webinar, hosted by Alec Baldwin, I discuss why new nuclear is obsolete now that enhanced geothermal is available. Wind-solar-batteries also obviate its need. Webinar also discusses 7 reasons nuclear is useless, polluting & an energy security risk.

Unheard of

8 straight days in January of WindWaterSolar meeting >100% of demand in California.

Gas down 66% v '23
Batteries up 387% v '23
PV up 127% v '23
WWS up 29% v '23

Horrible idea and only exacerbates problems. Solves none.

Do We Need Miracle Technologies to Save the Planet?

No. The solution is to electrify most all energy, use direct heat for the rest, and obtain the electricity+heat from wind, water & solar while using less energy

And for those who try to divert attention from the much more rapid growth of renewables in China than in the U.S. by pointing out China's high coal use...

Coal power generation falls in China and India for first time since 1970s
www.theguardian.com/business/202...

.@CaliforniaISO now has 14.7 GW/55.2 GWh of batteries.

Enough to meet 61.7% of avg power demand and 33.5% of max demand in 2025 for 3.8 h.

Can be seen in yesterday's record-setting 50.43 GWh battery discharge onto grid

As a result, gas down 68% v '23
