A bit of future-gazing which I can't be bothered spinning into a 15,000 word Gartner report.
In the UK we have a competitive electricity market. Only one set of wires comes to your house, but you can buy your electricity from a number of providers. Some only offer organic, corn-fed, Wind Farm power - others promise price stability - another gives you a discount at their electric car chargers - one gives you loyalty points at a supermarket.
We increasingly have smart meters. Second-by-second they measure our energy consumption and report it back to our power suppliers.
Domestic appliances are increasingly coming with Internet connectivity. We may laugh at the "Internet of Shit" - but soon every device we own will come with an app. We will control them from our phones, and they will report back their usage to their manufacturer.
Let's mash these ideas up.
According to the Energy Savings Trusts' report "Powering The Nation" a typical fridge/freezer uses 427kWh per year.
At an average price of 15p/kWh that's an annual running cost of £64.
Suppose your fridge manufacturer buys electricity in bulk at wholesale prices. The current wholesale price per MWh is £40. That's 4p/kWh. Or about £20 to run a fridge for a year.
Would you buy a fridge which costs £100 more but comes with 5 years worth of free energy?
You register your fridge online. It *wavy hand technobabble* talks to your smart meter and tells it how much electricity it has used that day, the sum is deducted from your bill.
Perhaps it does clever things like works out when the spot price for electricity is low and then cools down. Or it keeps your food a little bit warmer when energy prices are high.
Or perhaps it could *mumble mumble* blockchain *something something* cloud computing?
Is this the future? I think so.
I've been reviewing WiFi connected plug sockets which measure how much power an appliance consumes. They cost about $10 per unit at retail pricing. Soon it will be normal to receive an electricity bill which shows you just how much your Playstation 5 costs to run.
Your typical bill will tell you how much energy each of your appliances use. At which point it will become obvious that replacing your old TV with something newer will save you money in the long run.
Tesla gives customers £50 worth of "free" electricity with their cars - but that's only at their branded charging stations.
In the future, a new electric car will come with 10,000 miles worth of "free" electricity when you charge at home. You won't notice an extra £300 on the price of a new vehicle, and the manufacturer can securitise their wholesale energy purchases.
Your appliance talks to your smart meter which talks to your energy provider. With a little bit of thought, this could change how we buy energy consuming products.
