Snøhetta has just completed an office building in Trondheim that produces more than double the amount of electricity that it consumes. If you recall my recent post on Norway's new coastal highway, you may remember that Trondheim is the northern terminus of highway E39. I mention this because of access to sun. Latitude 63.43.
The office building is about 18,000 square meters and it is wrapped with about 3,000 square meters of solar panels. The roof is angled at 19 degrees in order to maximize sun harvesting, and any excess electricity is fed back into the city's grid / neighboring facilities. Large batteries also help to help carry the building through the winter months (again, latitude 63.43).
Here are a few photos of the roof (via Dezeen):
I wish I had more of the details so that I could see how the numbers pencil. Hard costs, utility costs, office rents, government incentives/disincentives, embodied energy in the batteries, and so on. Because this looks like an extraordinary accomplishment for a city that is remarkably north.

I came across this map while reading up on Hurricane Dorian:
On Monday, Indonesia’s president, Joko Widodo, announced a plan to build a new capital city on the island of Borneo. The plan is in response to Jakarta's formidable environmental challenges. It suffers from some of the worst air quality in the world and is struggling with a severe subsidence problem, which, I understand, is partially (or largely) a result of climate change and the unregulated extraction of groundwater.
About 40% of the city now sits below sea level and the worst affected areas are supposedly sinking at up to 20cm per year. This gives Jakarta the dubious distinction of being the fastest sinking big city. On top of this, it is also one of the biggest cities in the world in terms of population. The Jakarta megalopolis has over 30 million people, placing it 2nd after Tokyo according to this list.
Here's a short video from the BBC that will give you some visuals to go along with the above. These are the sorts of urban challenges that will make you forget all about separated bike lanes and 45 degree angular planes. And they are not entirely unique to Jakarta. If you can't see the video below, click here.

It is a map showing the tracks of every known hurricane in the North Atlantic (1851-2013) and in the Eastern North Pacific (1949-2013). Major hurricanes (category 3 or higher) are shown in yellow and tropical cyclones (intensity less than category 3) are shown in red.
The map is from the National Hurricane Center. Some of their other maps include the points of origin for tropical cyclones (here is August 21-31 from 1851-2015) and the total number of hurricane strikes by U.S. county (here is Florida from 1900-2010).
What has happened is a catastrophe. UBS is already estimating the insured damages in the Bahamas to be between $500 million and $1 billion. But as is usually the case, the total economic losses will likely exceed the insured losses.
