grease floats.
when it flows in sewage and into our plants, it thickens as temps fall, separating in our settling tanks.
the churning water forms grease globs that build like snowballs, and operators remove them so they don’t clog the process.
listen. don’t pour grease down your drains.

Almost no STEM graduate of my acquaintance was taught basic concepts of labor supply and demand, empirical organizational dynamics, or recent economic history, making them enormously vulnerable in their professional lives. This is disciplinary arrogance but it serves external interests as well. 2/2

big late breaking news: the market monitor for the largest energy grid in the u.s., covering much of the midwest and mid-atlantic, has called to block new data centers connections to the grid, saying current course of growth assures regular blackouts
No more PJM data centers unless they can be reliably served: market monitor
The PJM Interconnection’s market monitor urged the Federal Energy Regulatory Commission to rule that large data centers can only come online if the grid operator can still meet reliability metrics.

What's the deal with balcony solar?

The FAA briefly halted flights into DCA following today’s shooting near the White House to allow a medevac helicopter to fly nearby.
Normal operations have now resumed, the FAA tells me, and inbound flights are coming out of holding patterns. No flights canceled.-CNN

Going after the last 5% of electricity supply CO2 reduction without reducing transportation emissions is lunacy.
I worry about mining for EV batteries, too.
But we can have a better quality of life if we substitute private cars for bikes, transit, infill development

Good figure from a recent ESIG report showing how marginal abatement costs in the electric sector start out low but increase sharply as you approach zero emissions.

#climaterisk China has flat fossil fuel growth for 6quarters (Structural decline in FF demand). India had a flat quarter (mild weather). Even with hydro down YoY (EU), we are basically flat on FF electricity growth. It's happening guys.
NEW | Solar and wind have grown fast enough to meet ALL new electricity demand in the first three quarters of 2025, leaving fossil generation at a standstill.
Ember forecasts that 2025 could be the first year since Covid-19 without a rise in fossil power.

'plant has bidirectional aFRR capability, can rapidly curtail its output during periods of high generation, reducing systems’ reliance on fossil fuel plants for negative control energy. It can also rapidly respond and produce power at times of low generation, even during periods of negative pricing'
Germany’s first grid-balancing solar project might be a ‘paradigm shift’ for energy
A modestly sized solar PV project in central Germany might have just ushered in a new era of renewables’ relationship with the grid.
