This post offers some thoughts on why electricity prices in Great Britain are so high, with a few reflections about what should be done about it.

I signed up back in late 2018 with Octopus Energy’s Agile tariff, which reflects the half hourly wholesale prices. My reason for signing up…


It is now widely recognised that we need to reduce emissions. However, there are many ways to do this, and lots of uncertainty in the decisions to be made.

Most governments handle this by letting the private markets innovate, taking risk in search of profit. In practice, this approach is…
