Did you know you pay more fuel tax on a single car journey than a billionaire does on a private jet flight?
Right now the gov is subsidising tax breaks, when they could be using that tax to generate billions for public services.

The main cause of the noise is something that will, sooner or later, hit every part of the network: “rail corrugation”.

3. Main takeaways, continued:
- Retail electricity prices, and price increases, are mostly about spending on poles and wires, not energy supply
- Renewables don't correlate with higher prices, but dependence on natural gas pretty clearly does

High-speed rail is coming to #Canada!
This week, federal government fast-tracked the Alto project.
Will link #Quebec City- #Montreal - #Ottawa - #Toronto , a corridor with half Canada's population.
Projected to carry 30 million passengers a year—twice US Northeast Corridor—on 300 km/h trains.
