A Just Transition to Zero on Climate Change

Here are my notes on two of the best talks on energy that I’ve listened to in some time.  They both get the scale and the tactical outline correct, according to everything else I’ve seen and my own gut instinct.

An Energy Plan the Earth Can Live With
1/28/19
Radcliffe
Daniel Kammen (http://kammen.berkeley.edu), Director of Renewable and Appropriate Energy Laboratory (http://rael.berkeley.edu)

[Part of a Radcliffe symposium on climate and data]

A just transition is a more apt title
RAEL began working on PACE financing in 2009
SWITCH model to define utility energy storage needs
Morocco is the only country which has met its climate goals so far
Demonstrate climate change in a model free way to speak with doubters - NASA's Arctic ice animation over time, the loss of 50% ice cover displays the reality of climate change better than numbers
US-China climate agreement in 2014 was the tipping point.  China will reach peak emissions and then decline around 2025
We have already warmed the planet by 1 degree C [since 19th century, 280 ppm CO2e]
Getting to 1.5 degrees requires carbon negative policies as well as zero emissions [Ray Anderson’s Interface now making 80-100 year carbon negative products and on track for zero environment impact according to their metrics]
CA has had the same energy per capita since about 1978, energy sector has increased only as population has increased [USA annual energy production has been 100 quads or less since 2000]
Carbon and time are more useful in sustainability than money measures
CA does not count large hydro or nuclear as renewables
60% renewables by 2030 and 100% by 2045 now law in CA
All new homes [low rise residential] zero net energy by 2020 in CA
All commercial buildings net zero by 2030 [he is still trying to figure out high rises [July 12, 2013 edition Zero Net Energy links list:  Pearl River Tower, Guangzhou, China 71 floor zero net energy skyscraper, whether it performs to specs is an open question - http://www.skyscrapercenter.com/building.php?building_id=454]

Carbon budget of 600 gigatons in 2017, according to Christiana Figueres
20% (?) drop in price for every doubling of production (in solar) - Moore's Law
Nuclear costs have been rising in the USA in the last few decades [Vogtle seems to be pushing back their completion date on two reactors under construction in USA]
Energy storage is declining in cost as quickly as solar ever did
Kenya is the Silicon Valley of East India
Pay as you go solar is growing quickly - 50 cents a day for small solar - now TVs, [computers,] and DC refrigerators are available [the future is high efficiency, low energy, I build from Solar IS Civil Defense/entry level electricity - light, phone, small batteries - to household, neighborhood, and town systems, different scales of islanding microgrids]
Solar is 30% more prevalent in white neighborhoods even when you control for income
Cool CA carbon footprint calculator which also gives recommendations about how to reduce - also for Germany and Japan:  http://coolclimate.berkeley.edu [We need a World Game for the benefit of all who will allow the benefit of all to work out how to provide bare minimums (and bare maximums) without destroying more than homo sap sap (the sap) already has]
Clean energy creates many more jobs than fossil fuels [and fastest growing jobs in most places are solar and wind, at least as a thought experiment]
40% of all USA renewables venture capital is in CA
Brazil's bagasse biofuel is now extending into the Amazon with disastrous results, food and forest production is being turned over to biofuels [too much of a good thing isn’t, balance portfolio of options within zero emissions framework - zero as an approachable goal as in TQM]
Carbon price should put back some money for research [and revolving loans]


Getting to Zero on Climate Change
2/7/19
Harvard
Hal Harvey @hal_harvey, author of Designing Climate Solutions, founder of Energy Foundation, Energy Innovation Policy & Technology LLC

By changing the averages moderately we've changed the extremes a lot
Electric grid, transportation, buildings, and industry - four sectors [he did not talk about agriculture but it’s in the book]
75% of all ghgs come from 20 countries [about 100 companies responsible for 71% of ghgs by one count - Pareto rules!! - https://www.theguardian.com/sustainable-business/2017/jul/10/100-fossil-fuel-companies-investors-responsible-71-global-emissions-cdp-study-climate-change] 
$5 trillion per year on energy and $6 trillion on infrastructure that establishes consumption patterns 
Converting brown $ to green $ is key [no mention of stranded assets or carbon bubble]
A few key policies for each sector are available [in the book]
Offshore wind smooths load when combined with land-based wind as onshore/offshore winds are different in time of day and speed [see bagasse comment above]
Demand response can make 100 million buildings into thermal batteries [electric vehicles are rolling batteries too]
RPS and grid flexibility are two proposals that work here [microgrids for resilience and disaster preparedness, which we will definitely need in the near term]
A green grid plus an electric car solves transportation [rolling batteries] but internal combustion engines will still be out there
50 mpg is probably the most effective standard, 60 mpg doesn’t buy you much more
ZEV mandates and fuel efficiency standards are the policies here, continuous improvement in standards; don't set a number set a rate of change
Building codes and appliance standards are effective levers [CA and EU net zero building standards, mass retrofit of existing building to net zero standards from EnergieSprong https://energiesprong.org, pilot in NY state, other net zero energy resources I know of are available from Switzerland and Belgium]
Agriculture, iron and steel, chemicals and plastics, cement, and waste management are the most ghg intensive industries
Carbon pricing, carbon standards for products, device efficiency standards [no mention of removal of subsidies for fossil foolishness]
Concentrate on the USA public utility commissions which means you need to talk to a little over 100 people
NRDC, Advanced Energy Economy, CLF, UCS know about working with PUCs

Mass Production of Net Zero Energy Retrofits for Single Family Homes

Energiesprong (https://energiesprong.org) is doing deep energy retrofits for existing single family homes using mass produced modular systems and installing solar panels to make old buildings net zero energy, meaning they produce as much energy as they consume.  They have completed 5000 houses since 2012 and plan over 14,000 with associated programs in France, Germany, the UK, Italy, and New York State.  

 and associated programs have done about 6000 houses in France, while they are just beginning in Germany, the UK, Italy, and New York state.
E=0: Transforming Homes into the Future, is a documentary film project, funded by Interreg North West, that chronicles the efforts being made in the past 3 years, to establish a net zero energy housing ecosystem across Europe.

More at https://energiesprong.org/e0-transforming-homes-into-the-future-the-movie/
Looks like a Green New Deal to me.  I’ll have to see if Alexandria Ocasio-Cortez and my Governor, Charlie Baker, know about this.

After the second Energy Crisis in 1979, Jimmy Carter wanted to insulate 90% of our homes by 1985 and get 20% of our energy from renewables by the year 2000.  Too bad the Reagan Administration stopped that idea dead in its tracks.  It’s one reason why I say “Reagan killed us.”
That energy policy wasn't about climate change.  It was about energy independence because of the two in a decade Energy Crises (1973 & 1979) under Nixon, Ford, and Carter and included much shale oil fossil foolishness as well.

In 1980, the goal was 20% from renewables by 2000.  Renewable energy today, in 2019,  two decades later than that, is at about 18% (source:  http://fortune.com/2018/02/18/renewable-energy-us-power-mix/) .

My Approach to Climate Change

1.
My approach to climate change is
100% renewables ASAP
zero emissions economy ASAP
carbon drawdown ASAP
geotherapy (not geoengineering) ASAP

Resources: http://drawdown.org
https://www.crcpress.com/Geotherapy-Innovative-Methods-of-Soil-Fertility-Restoration-Carbon-Sequestration/Goreau-Larson-Campe/p/book/9781466595392
http://bio4climate.org
http://soil4climate.org
http://solarray.blogspot.com

At least as a thought experiment.


2.
I start from Solar IS Civil Defense, which is necessary NOW
in case of weather or other natural disaster, whatever you believe about Climate Change or Sanity Clause.

10 bucks buys a solar light and charger today, just go Internet shopping. That's a personal electric solar civil defense, the basics of light, communications, and extra batteries. 10 bucks is also the price of a hand-crank light and charger. Add a bicycle charger (or electric bike) and you have "free" electricity for as long as the batteries hold a charge and the chargers work.


3.
Simple solar and energy efficiency can be taught, to those who want to know, fairly easily and can be quite effective
A South-Facing Window Is Already a Solar Collector

Solar windowbox air heater
https://youtu.be/lTOe2OYSPlw
Insulating Roller Shade

Six pack of solar
https://youtu.be/KTLBsxI-Xl8
Recycled solar

I used to do workshops on simple solar and broke one down into a series of short videos:
the others are available at https://www.youtube.com/user/gmoke/videos


4.
Simple solar can become an economic lever and non-violent economic practice, a technological adaptation of Gandhi's concept of swadeshi, local production, what he called the heart of satyagraha. I imagine a solar swadeshi (http://solarray.blogspot.com/2005/05/solar-swadeshi-hand-made-electricity.html) that becomes a solar walkaway or an electrical grid boycott to add a little impetus to the growing tide of Extinction Rebellion (anybody else see a resemblance to the Trainites of John Brunner's Sheep Look Up?) and the Sunrise Movement.


5.  Since scientists tell us that we have about a decade to do something to reduce climate calamity, somebody should be scheduling out the next 10 years, 3,650 days, for climate action, month by month, week by week, day by day to do what is ecologically necessary to restore the atmosphere to preindustrial levels of CO2 (270 parts per million) ASAP.

Everyday Solar

There's a lot of solar street furniture that's appeared around town in the last few years.




Like this solar garbage can.



Or this bench with solar phone charger.








And this solar powered pay station for the local bike share.







There are even solar signs.


Increasingly, solar electric installations, big and small, are becoming everyday objects.

The renewables transition is well underway and gaining speed.  Solar is weaving itself into the fabric of this 21st century world.  Soon it will be almost invisible, ubiquitous, and available 24/7/365.

Checking in with the World's Winds

I like to see the maps of the Arctic Jet Stream every day or so (http://squall.sfsu.edu/gif/jetstream_norhem_00.gif).
They look like dragons and other creatures
chasing each other around the North Pole.

Then I look at the Global Map of Wind, Weather, and Ocean conditions (https://earth.nullschool.net)
which animates the winds and ocean currents in what seems like real-time
in full color
coded according to the speed.
I look for where the rare red winds are.

Usually, last, I pull up the World Cloud Cover map (http://www.ssec.wisc.edu/data/comp/wv/LATEST_WV.gif)
to see how it relates to the other two images
and make sure the equatorial rainforests are
still making rain.

Sometimes, late at night 
I look at the Northern Lights 
from the Churchill, Manitoba Northern Studies Centre live camera (https://youtu.be/kDWh0ijwCp0).
Even when the Northern Lights aren’t shining,
I’ll often just
listen to the sounds
of that distant wind.

It reminds me where I live.

The Cost of Personal Solar Power

                                                                                       
 I bought a solar hand crank radio flashlight with USB mini plug DC output about 5 years ago.  It cost around $30.  It provided in one package what we are supposed to have on hand in case of emergency or disaster - light,  cell phone or radio, extra batteries - in one package.  This is also entry level electricity for the over 1 billion people around the world who don't have access now.


A month or two ago, I bought a second solar hand crank flashlight.  No radio, no DC output.  It cost around $4.




Before the invasion of Afghanistan, NATO forces distributed solar/dynamo AM/FM/SW radios to the civilian population. After the invasion, they gave away more.  The NATO radios charge only the internal hardwired battery. A single additional circuit would allow them to charge external batteries. If the solar/dynamo could charge batteries, then you could use batteries in rotation, charging one set while using another. The solar/dynamo would be a source of electricity day or night, by sunlight or muscle power, at least for the lifetime of the batteries, crank, and PV panel. 


Combine this with bicycle generators that charge batteries in the course of daily riding and you have the possibility of providing survival level power to everyone in the world now.


In 2016, the world reportedly spent $4.61 billion per day on the military or $1686 billion, equivalent to 2.2% of the global gross domestic product (GDP) and $227 per person. 

Source:  https://www.sipri.org/sites/default/files/Trends-world-military-expenditure-2016.pdf

Solar electricity now costs from $4 to $30 AA survival or emergency and disaster power.


The image I have is of a

solar swadeshi, hand-made electricity.
Instead of turning the handle
of the charkha spinning wheel
making thread 
for khadi cloth
an hour a day as Gandhi did,
turning the crank of a dynamo 
or riding a bicycle a half hour a day,
the direct production of survival power
for yourself, your family, and your community,
swadeshi, local production.

Solar Backpack and Bicycle Back Up


My backpack became a solar backpack when I sewed a $5 solar tail light and a $10 solar headlight to it.  The plastic blister pack is the holder for the headlight.  I've been assembling my own solar backpacks from off the shelf materials for close to a decade and a half now and this is the third version.













This Solar headlight (links to sellers are from a search made on 11/26/17 and you should probably check others out even though these are now commodity products made in gross quantities)
https://www.gearbest.com/bike-lights/pp_425123.html
costs about $10.  I've been using one for a year or two and it works fine.  The on/off button top came off during the first winter but it hasn't affected the switch's performance.


The solar light comes with a mini-USB to USB plug so I can supply battery power to another small device.  















This Solar tail light
costs about $5 and, again, I've been using two for a year or two, one on the rear fender of my bike and another sewn to my backpack, given one or two away, and they work fine. 


I have just ordered this bicycle chain charger with battery and USB connection for about $50 
I want to see how that works out.

The combination of solar and bicycle power gives anyone essential energy autonomy whatever the state of the grid.  Or the world.

The fact of the matter is, for less than $100 dollars you can have a 5, 10, or 20 year, depending upon the quality of the equipment and based upon my experience, supply of basic electricity:  light, phone, radio, batteries, possibly a computer....
Small solar and bicycle power can also be entry level electrical power for the more than 1 billion people who don't now, in 2017, have access to reliable and affordable electricity.

This is one reason why I say Solar IS Civil Defense.

It is also why I say a Solar Swadeshi (http://solarray.blogspot.com/2005/05/solar-swadeshi-hand-made-electricity.html) is extremely practical and an entry into Gandhian economics, nonviolent economics, and a new sense of independence and self-reliance.

4 Symmetrical Tetrahedra of 5 Platonic Solids



This is a video of a magnetic model of the Cube and the Tetrahedron broken down into its smallest symmetrical tetrahedra, what Buckminster Fuller called the A and B Quanta or mathematicians call Schläfli orthoschemes (I think).

The A and B Quanta make the equilateral triangle Tetrahedron (4 sided solid), square Cube or Hexahedron (6 sided), and equilateral triangle Octahedron (8 sided)

The A Quanta is 1/24th of a Tetrahedron, the smallest symmetrical tetrahedron to make up a Platonic solid.  Here is the net of the A Quanta which can be folded to make the left and right hand versions, both of which are needed.
                                                                           




                                                                                                                                                                             
The B Quanta plus the A Quanta makes the Cube or Hexahedron 
and the Octahedron,
two other Platonic solids
48 A Quanta + 24 B Quanta = 1 Cube
2 Cubes = 1 Octahedron







                                                                                                                                                                                 






A third, the Dodeca Quanta, builds the Dodecahedron

120 Dodeca Quanta = 1 Dodecahedron



And a fourth,
120 Icosa Quanta = 1 Icosahedron












I've made magnetic models of the 5 Platonic solids with the magnets in the centers of the faces of the polyhedra.  The A and B Quanta have the same volumes and I suspect share that volume at the same scale, all four tetrahedra share one common right angle triangle, but I haven't tested that hypothesis.

Since I saw this video, I think the next model should be a set of these Quanta built as class 2 tensegrities with ball magnets at the vertices.  In fact, I'd commission someone to build it, for the right price.
