We just made this graph showing most people in the world could get by on just some solar panels and batteries.

The X axis is basically latitude, but we filled in how many people live between the equator and a certain latitude.
The Y axis shows the amount of solar and batteries needed

Likely true, but to comply with electrical codes in USA & Canada (which could otherwise oblige you to upgrade service, sometimes at considerable $) you’ll need a power control system (see UL 3141) that actively controls between loads

Also, having the battery in a device already being installed significantly reduce the cost of storage… so much of the cost of residential battery storage is the labour, sales and permitting…

In addition to the value created by shifting off peak at the wholesale & utility distribution scale, battery integrated appliances could also coordinate to avoid peaks on building systems.

Like all the HPs in MURB could coordinate across a mesh network to not exceed capacity of building…

Legacy air-conditioning giant Carrier has a simple solution to ACs stressing the grid: Pair them with a battery that charges up when power demand is low.

Here’s how it’s testing the concept.

If this keeps up, if the air stays toxic due to constant flaring, you’ll see local support for LNG expansion in the Prince Rupert and Kitimat area vanish very rapidly.

This isn’t great, sounds like break-in flaring at LNG Canada is becoming routine. And your regular reminder if a flare is yellow the methane isn’t being fully combusted - if so it would be blue. That means VOCs, CO, PM2.5&10, etc. thenarwhal.ca/kitimat-lng-...

BC friends, important piece by @iglikaivanova.bsky.social

She writes: BC’s own source revenue—taxes, fees & royalties—has plummeted from 19.2% to 15.4% of GDP over 25 years. This drop represents $16.8 billion in foregone revenues annually."

Tax cuts drive the deficit; progressive tax ⬆️ needed 👇

BC folks! Outstanding piece here by @iglikaivanova.bsky.social, co-ED of @bcpolicy.bsky.social.

BC has a revenue problem, not a spending problem

The solution to BC’s fiscal challenges isn’t spending cuts. Instead, BC needs progressive revenue measures.

Other strategies to “square it”:

plant a pollinator garden to help the insects where there was previously monoculture grass.

Give $ spent on organic to nature conservation / farm workers advocacy, esp migrants (they need it these days)

Etc etc. 🙂
brendanmcewen.bsky.social
I used to buy organic… now I generally dont. I think it is largely a marketing hustle intended to separate those with means from their $. And a net bad, given yield impacts.

I do wish there was an independent food labeling scheme growers could apply to that had good contextual criteria.

Youth unemployment isn’t just a statistic. As these testimonials indicate, it’s a crisis shaping the lives & futures of young people.

A Youth Climate Corps could put thousands to work while supporting climate & community. Take action below 👇

If the world diverts tens or hundreds of millions of hectares of additional cropland to biofuels, it would lead to large-scale deforestation and ecosystem conversion, and would be a disaster for our efforts to fight climate change and biodiversity loss. It would also lead to higher food prices.

This is a great short piece worth thinking about when it comes to transportation & urbanism.

“We cannot optimise both proximity and mobility. Proximity and Mobility cannot be friends. We settle into one of two worlds: (a) high proximity, low mobility or (b) high mobility, low proximity.”
What we mean be high proximity/low mobility verses high mobility/low proximity.

there is this notion that electrification is driving car bloat - I really don't see it! Sure EVs are lower cost to operate, but trend towards the (very dangerous) large pickups & SUVs is predominantly driven by North American automakers selling ICE
brendanmcewen.bsky.social
As @cleanenergycanada.org documents, Europeans have access to lower cost EVs. The Federal govt of Canada should enable access.

What really strikes me about these cars is their modest size! So much safer for pedestrians, etc.

Vertical solar panels didn't decrease wheat yields at all.

Although exposure to sunlight was decreased, wind protection seemed to make up for it.

I'm writing something on why Canada develops megaprojects instead of innovation systems

In 1957 staple theorist WT Easterbrook wrote Canada puts "a high premium on bigness in entrepreneurship" - that our capitalists seek security in gov't infrastructure projects.

I see AI-generated text everywhere in academic writing. And it's making me a bit sad.

It feels like all the argumentation is homogenized, and stylistically represents a consulting report (McKinsey style), with a lot of empty strawman arguments and other logical/intellectual blunders.

This is the primary contributor to the acceleration in global warming in recent years. Cutting air pollution saves lives and is unequivocally worth doing, but it is also driving about a quarter (~0.14C) of the approximately 0.5C warming the world has experienced between 2007 and 2024.

I have a new @nytimes.com guest essay w/ @davidkeith.bsky.social about sunlight reflection. We note its not a solution for climate change and at best a band aid to treat systems, and suggest if its ever done it should only be to replace the cooling from air pollution today:
Opinion | A Responsible Way to Cool the Planet
A small, carefully scaled geoengineering program could compensate for the loss of cooling as we eliminate sulfur pollution.
