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… Continue reading →

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… Continue reading →

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… Continue reading →

The British Summer Generates 1.5 MegaWatts Per Roof

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… Continue reading →
