“Every act of energy conservation… is more than just common sense: I tell you it is an act of patriotism”*…
But how do we best honor that admonition? The estimable Saul Griffith has observed “We need a proportional quantitative understanding of energy use, for everyone.” Now, Hannah Ritchie (Deputy Editor of Our World in Data and Senior Researcher in the Programme for Global Development at the University of Oxford) rides to the rescue with an elegant tool that compares and quantifies (in both watt-hours and usage cost, in both the U.S, and the U.K.) the energy consumption of different products and activities.
Try it: “Does that use a lot of energy?” from @hannahritchie.bsky.social. Background in her newsletter.

As we watch our wattage, we might send wild birthday greetings to Bernard Frank; he was born on this date in 1902. A conservationist, forester, and wilderness activist, he had a long, engaged career in conservation concerns, especially in the D.C. area, where he was a leader in organizing the Rock Creek Watershed Association which worked to restore and preserve the area around Rock Creek in Washington, D.C., and Maryland and in the effort that lead to the creation of the Chesapeake and Ohio Canal National Historical Park. He was honored for his work in this region with the naming of Lake Bernard Frank in Derwood, Maryland. But Frank is probably best remembered as one of the eight founding members of The Wilderness Society.

Worth noting that "Normally Weird and Weirdly Normal" by @robinince is only 99p on #Kindle today only, while Hannah Ritchie's data-driven climate change Q&A "Clearing the Air" is only £1.99.
Unusually, these prices aren't matched in the #Kobo store, but they will refund the difference *in store credit* if you make a price match request.

"It makes little sense to waste electricity to produce hydrogen — which has conversion losses — rather than directly powering an electric car or heat pump."

#Reading #NotTheEndOfTheWorld: How We Can Be the First Generation to Build a Sustainable Planet by #HannahRitchie
#Auspol #NuclearPower #ClimateHannah Ritchie is a data scientist who works on climate issues, and lead analyst at Our World in Data website which as lots of stuffs about climate, all in the public domain
tbh i don’t read a lot about climate cos a) most of it is over my head and b) as lily tomlin said, reality is the leading cause of depression amongst those in touch with it
Not the end of the world is a brilliant book on both counts, because it’s written in very accessible language, and provides a healthier perspective on all the big issues.
A related benefit is Ritchie is not a politician, billionaire or spin doctor and, so far as I can tell, can probably be trusted.——-
IMAGE DESCRIPTIONS - book sample text
Let's go back to 2009. You're the prime minister of a low-income country, and you want to build a new power plant.
One-quarter of the population does not have access to electricity at all. Many of those that do can only afford to consume very small amounts. Hundreds of millions live in energy poverty. It's your job, as the leader, to improve the lives of the people in your country.
You have to decide which type of power plant to install.
Obviously, cost is a big factor. We're going to compare electricity sources based on a metric called the 'levelized costs of energy' (LCOE). You can think about LCOE as the answer to the question: what would be the minimum price that my customers would need to pay so that the power plant would break even over its lifetime? This includes the cost of building the plant itself, as well as the running costs for the fuel and operations.
Here are your options, and how much each will cost per unit of electricity:17, 18
* Solar photovoltaic (PV): $359
* Solar thermal: $168
* Onshore wind: $135
* Nuclear: $123
* Coal: $111
* Gas: $83IMAGE DESCRIPTION - second text sample
In just 10 years this has changed completely. It's now 2019, and you have to make the same decision. Here are the prices
now:
* Nuclear: $155
* Solar thermal: $141
* Coal: $109
* Gas: $56
* Onshore wind: $41
* Solar photovoltaic: $40
In just a decade, solar photovoltaic and wind energy have gone from the most to the least expensive. The price of electricity from solar has declined by 89%, and the price of onshore wind has declined by 70%. They are now cheaper than coal. Leaders no longer have to make the difficult choice between climate action and providing energy for their people.
The low-carbon choice has suddenly become the economic one. It's staggering how quickly this change has happened. -

"Kirjasta on lyömäaseeksi monia ympäristötutkijoita ja -aktiiveja kohtaan, eikä Ritchie varmasti tätä ole tarkoittanut".

Finally found some time to start reading #HannahRitchie : "I don't think we're going to be the last generation. The evidence points to the opposite. I think we could be the *first* generation [...] that leaves the environment in a better state than we found it." #ClimateOptimism #ClimateChange #Sustainability #Positivity

I saw Hannah Ritchie's book "Not The End of the World" referenced in the Just Have a Think episode a couple of weeks ago. It looks like a smart, data-driven and doommonger-free assessment of how we can build a sustainable planet, starting from where we are now.
Just noticed the e-reader version is on 24 hour sale at Amazon and Kobo for £1.99, so I've picked it up.

How to reduce bird and bat kills from wind turbines, by #HannahRitchie
- Turn off wind turbines at very low speeds when bats are around
If turbines are off at wind speeds below 6.5 m/s, bat kills are reduced by 93%.- Also, stop wind turbines when migratory birds pass by (which is very occasionally)
- Don’t put wind farms in high-risk areas for birds and bats
- Fewer larger turbines are better than many small ones
And more!

Enjoyed this conversation between Hannah Ritchie and Bill Gates. Their optimism is infectious.
I think this part is especially true: "We fund a lot of amazing carbon removal companies. How much that ends up being part of the solution, that will be up to governments."

"Stop Telling Kids they’ll Die from #ClimateCrisis –we need to chge this narrative. We need to stop putting tht burden on our kids– not only b/c it’s cruel, but because it’s wrong & ineffective in helping us turn things around.
We don’t need to pull the wool over their eyes...pretend that there's no problem. But we can & should focus on what we can do about it. B/c we can do something about it. A lot."

A punch in the face of petrol cars, by #HannahRitchie in her newsletter.
==
For every dollar of petrol you put, you get just 20 cents’ worth of driving motion. The other 80 cents is wasted.Now board an #ElectricCar. For every dollar of electricity you put in, you get 67 cents of driving motion plus 22 cents of energy recovered from regenerative braking. That means you get 89 cents’ worth out.
==Amazinlgy inefficient petrol cars we drive.

@ClimateChris I'd be curious to learn about the discrepancy between your statement ("6% of GHG emissions are transport related") and the conclusion of this @ourworldindata publication by #HannahRitchie, which tells me, we can basically neglect the question of transport and focus more on what we eat:

"Why don't you bother China??" say some of the climate deniers.
Let's look at #China and #renewables with #HannahRitchie
China adds *every year* as much #solar and #wind as the *total* consumption of Spain or UK
China's tota solar and wind output is AS HIGH as the total electricity consumption of Brazil or even India.
China is adding renewables 50 times faster than other major economies.

Yes, #criticalminerals are important for the transition to #renewables, and we should think hard about reducing their impacts and building more justice and equity into their extraction...
BUT, as this #hannahritchie piece points out, switching to RE from fossil fuels will radically reduce the overall level of extraction and mining.

"Perfect solutions: the enemy to solving our environmental problems" by #HannahRitchie
People are looking for perfect solutions, but they’re not going to find them. Waiting for the perfect fix is the same as doing nothing.
"Building #solar, #wind, and batteries means digging #minerals out of the ground. Manufacturing #batteries need some energy. #Nuclear energy comes with a small risk of an accident"
(my note: nuclear is a disaster in terms of project management)

From #HannahRitchie's newsletter (#Sustainability by numbers):
#ElectricVehicle #batteries would have cost as much as a million dollars in the 1990s
In the last 30 years, the price has fallen by more than 98%.
#EVs didn’t stand a chance of making it commercially until the last few years.
They’re not just cheaper, they’re much smaller and lighter too.
Batteries have followed what we call a ‘learning curve’, where the more you build, the cheaper they become.
