“Instead of just swapping hydrocarbons for renewable imports, the new energy system creates very different types of dependencies. With oil & gas, the dependence is on the fuel supply itself; with renewables, the dependency rests on replacing physical assets & the use of critical minerals.”

SoCalGas is using *efficiency funding* collected from ratepayers to push LA wildfire survivors who lost their homes to build back with *gas* rather than all-electric.
Truly bleak stuff. This should not be allowed. Where are our regulators at the CPUC?

LA Wildfire Survivors Want to Rebuild All-Electric, but a Utility Is Using Customer Funds to Incentivize Gas Appliances - Inside Climate News
California’s utility regulator said it would eliminate ratepayer-funded incentives for gas appliances in new construction, but created an exception that allows rebates for them in wildfire rebuilds.

Grid bottlenecks aren’t a failure of the energy transition — they’re proof it’s working.
Renewables got cheap fast, and now the grid has to catch up. Time to build the wires for the clean energy system we already have.

The shift to EVs is happening—fast. Manufacturers can either embrace the long-term transition or chase short-term gains by clinging to petrol and diesel.
China is choosing the long view. Many in Europe aren’t. The risk? Ending up with cars no one wants, lost market share, and shuttered factories.

Lots of news coverage this morning about £28 billion investment approved to upgrade the UK's energy network.
BUT: The majority of the spending – £17.8 billion - announced today is to maintain Britain’s gas networks rather than build new transmission lines.

Data centres are energy hungry but what if we could use their waste heat to heat our homes?
That's exactly what happens in places like Finland: Cities are tapping the vast amounts of waste heat generated by data centres, and feeding it into district-heating networks.

In 2024 less than 10% of Danish electricity was from fossil fuels.

A positive correlation exists between the number of available smart tariffs and the market penetration of EVs in Europe.
This means that with a growing EV fleet, there is also a growing choice between services and tariffs.
