  • The EU does that since the emissions are taxed via the EU ETS and it just results in the most expensive electricity in the world.

  • The idea is interesting but unfortunately most of the people don't know the electricity price even now without this mechanism. This should be displayed on top of every washing machine everywhere to make it works

  • My electricity provider has a near real-time graph of energy generation by source (wind, solar, coal, etc.) and I use this during off-peak times to decide when to use or avoid certain loads. For example I love charging batteries when solar is producing more energy than is being used by customers.

  • This is kind of a stupid preposition. the cheapest hour should be the cheapest with carbon externalities priced in. There are lots of times where it is both logical and good for the cheapeat hour to not be the lowest carbon (i.e minimum run times on foasil fuel plantspushing should hours very cheap because they are needed for the peak hours or forecast renewable drop off.) If the market isnt pricing the carbon externalities that is a seperate issue.

    further the grid price only represents variable costs, congestion, and bidding strategies of gen to try and also recoup fixed costs and make a profit. This may translate to cheaper when lower carbon because variable cost is zero for many renewables but making it explicitly happen breaks the market price finding mexhanism and is probably an even larger aubsidy to renewables, which in itself is stupid vs just pricing the carbon externalities and letting the market decide.

  • In my country (for people with a so called "dynamic pricing" contract) the price of electricity already drops significantly when we have a load of green energy (wind, solar). I guess this is just a side effect of not having a well-balanced grid. But still that's already kind of a CO2-based pricing - although not directly

  • The harder question is probably whether dynamic pricing changes behavior without mostly becoming a penalty for people who have less flexibility in when they use electricity

  • Mine is just flat pricing but I do try to align it.

    UK has big variations in carbon intensity depending on how solar & wind is doing, so easy enough to make a small effort to align discretionary things like washing machine with that

    There is also a very nice dashboard for UK grid that shows clearly what's going on at any point in time.

  • Here is an analysis from Germany: Quarter-hourly spot prices compared to the share of renewable energy generation in total generation. A higher share of renewables puts massive downward pressure on the spot market electricity price.

    https://www.energy-charts.info/charts/price_scatter/chart.ht...

    Since price elasticity for electricity is very high, the market cap decreases by approximately €150,000 for every additional GWh of renewable energy production. A single additional offshore wind turbine with an annual output of 60 GWh reduces the combined revenue of all electricity producers by about €9 million per year that it is in operation.

    Blocking wind power and solar projects only serves to secure the profits of monopolists and oligopolists in the electricity market, but causes massive harm to the economy.
