Opinion | How Long Can America’s Climate Hypocrisy Last? – The New York Times

On the same day this month that the head of the International Energy Agency confidently declared that fossil fuel demand would peak this decade, the climate advocacy group Oil Change International found that the United States would be responsible for over one-third of all planned fossil fuel expansion through 2050. The following week, as President Biden emphatically called climate change an “existential threat” and announced the creation of a climate conservation corps, the United States broke a record for oil production.

It’s nothing new for climate ambition and climate hypocrisy to flicker back and forth like the two faces of a lenticular hologram. When the United States helped forge the Paris agreement in 2015, it still forbade the export of crude oil and was shipping a pretty trivial amount of natural gas overseas. But that legal ban was lifted the same month the climate agreement was reached, and today the United States — already the biggest producer of oil in the world and its biggest consumer — is also the world’s second-largest interregional exporter of crude. In 2015, the United States was shipping out just 1 percent as much liquefied natural gas as Qatar, the world’s biggest exporter; today, it is the world’s largest exporter, as well as the largest consumer and largest producer.

How Do Substations Work?

Untangling the various equipment you might see in an electrical substation.

This is a very interesting video. Substations do a lot more then just stepping down the voltage from high-voltage transmission lines. They carefully control the output voltage and frequency, bring together often multiple power lines feeding into the system, they can disconnect and connect lines for servicing and repair. In many ways, substations really are the brains of the local power grid.

The developers of a transmission line that is essential to meeting New York’s clean energy goals and shutting down polluting New York City power plants say they’re still on track to finish construction in 2026 — despite pushing for nearly $3 billion in increased ratepayer subsidies.

The recent ask by the Champlain Hudson Power Express is the latest effort by renewable energy companies to press New York regulators for more public aid for their projects — putting the state in an increasingly difficult bind as it steams toward ambitious climate goals by 2030.

Refrigerants How they work in HVAC systems

In this video we will be learning how refrigerants work in HVAC systems such as refrigerators, air and water cooled chillers as well as split a/c units. The refrigerant removes heat from the building and transfers it into the ambient outside air to produce air conditioning.
