How much should it cost to charge a car?

A large electrc charger with the Shell logo on it.

Back when nuclear power stations were first proposed, we were promised "energy which is too cheap to meter". That is, the cost of electricity would be so low, invoicing for its use would be prohibitively expensive. Well, that didn't exactly turn out that way! But as our electronics have become more efficient, the cost of…

Even when I had a petrol car, I boycotted Shell - refusing to use their petrol stations. I thought that would continue once I got an electric car - no dino-juice for me! My car has more than enough range for me, but on a recent journey I decided it would be prudent to do…

A graph of energy consumption.

(Long and data-filled post ahead!) I've switched to energy provider Bulb (£50 off if you join using that link). They offer a "peak time" electricity charge which looks like this: 23:00 to 07:00 = £0.0815/kWh 07:00 to 16:00 = £0.1235/kWh 16:00 to 19:00 = £0.3263/kWh 19:00 to 23:00 = £0.1235/kWh By contrast, the standard tariff…

I've been driving EVs for a few years now - and people often ask me about running costs. I can't tell you what your insurance, maintenance, or leasing costs will be - but I can show you how much it costs to drive. Here's a fairly recent trip in my Renault Zoe: That's a mixture…

My solar panels deliver pure Direct Current electricity into my house. All my house has Alternating Current circuits. Therefore, I need an inverter to change the DC to AC. This is inefficient. Most of the electronic devices I own are powered by DC. So I plug little wall-warts into the AC sockets to convert back…

The British Summer Generates 1.5 MegaWatts Per Roof

by @edent | # # # | 2 comments | Read ~247 times.

A couple of years ago, we had solar panels installed on our roof. We based our power generation estimates on the Europa Solar Calculator which estimated that they would generate around 2,700 kWh per year. Every few months we take a reading and see how the panels have been performing. Our meter reading for the…
