Self-driving cars could save energy

Posted by Alex Barrett on 23 November 2016 at 11:30 am

Self-driving cars could save energy

In 2014 transport accounted for 38% of the UK’s final energy consumption [1]. The majority of this was due to the use of road vehicles, both for private transport and for business. Cars account for a considerable fraction of the greenhouse gasses we emit. As roads get more congested the…

Was switching my energy supplier worth it?

Was switching my energy supplier worth it?

OK, so I switched a little while ago and I wanted to tell you how painless it has all been. The new supplier, Bulb, wrote to me almost immediately to welcome me to their new community. They introduced me to their website where I will be able to post meter readings to keep track of my usage (w…

Heat Pumps: Air source or ground source?

Heat Pumps: Air source or ground source?

Heat pumps are devices that use a small amount of energy to move heat from one place to another. During cold weather they extract heat from outside sources and pump it indoors. This process can be reversed during summer in order to act as an air conditioning system. The heat pump circulates a…

How will degree days help you measure energy savings from heating and insulation improvements?

Suppose you are retrofitting your house, improving its insulation or installing a more energy efficient heating system. You will want to know how much energy you are saving, but with heating costs this can be tricky to figure out. This is where "degree days" can help. Temperature, a…

Can we generate 100% of our energy from renewables?

Can we generate 100% of our energy from renewables?

In early May of 2016 Portugal covered all of its electricity demand for four days using only renewable sources, energy prices in Germany briefly turned negative, as renewables met almost all of the demand for a day, and the UK didn't use any coal fired power stations at all during several low…

How does a full log box keep you and your wood stove happy?

How does a full log box keep you and your wood stove happy?

Good preparation is important if you want to heat your home efficiently with a wood stove. What you want is ‘maximisation of heat out’ and ‘minimisation of effort in’. The practical and psychological benefits of advance preparation are clear to me. Practical benef…

Should you open windows in winter?

Should you open windows in winter?

When it comes to energy saving the less heat your house loses the better. One of the best ways to accomplish this is by draught proofing. By stopping warm air from leaking out of your house you prevent heat loss and so reduce the amount of energy you have to use for heating. This suggests that fo…

What are the basics of a modern biomass boiler?

In this video SuperHomer Mark Brown introduces us to the wood pellet boiler he chose to get installed in his 1980s five bedroom detached family home in 2009. Mark's boiler is substantially larger than the usual gas boiler and is installed in the garage. Some boiler models do not take…

I switched energy supplier and saved

Posted by Gabby Mallett on 3 November 2016 at 10:05 am

I switched energy supplier and saved

The first thing I had to do was work out how much energy I had used last year. That wasn’t as difficult as I thought it would be as, rather helpfully, my current energy provider does give me an annual statement and puts on each month’s bill a note of my previous year’s energy us…

Energy vampires are real and exist in your home!

Vampire draw, phantom loads and no-load power are all terms used to refer to the phenomenon of electricity being consumed by appliances that are “switched off” or in "stand-by mode". These appliances can run up your electricity bill and can easily add up to a hundred po…

How should I season and store wood for my stove?

What are the aims of wood storage and why it is so important? I spoke to Stewart McIlroy, SuperHomer and wood stove owner about his advice for wood storage. Stewart says that the main aim of storing wood is to ‘season’ it. Newly chopped wood contains a high percentage of water whi…

It is energy switching time again

It is energy switching time again

As we approach winter, and most of you will already have turned your heating on, I wonder how many of you are thinking about switching.  Why would you want to have your most costly months on that stupidly high tariff you are paying because you haven’t bothered to shop around? In the su…

Does plastic have to come from oil?

Plastic is all around us. Over the course of the 20th century it has become one of the most commonly used materials for all manner of goods and appliances. It is estimated that 288 million tons of plastic were produced in 2012 [1]. But plastic is made from oil, the same non-renewable crude oil re…

Heat pump tumble dryers: Eco-friendly or not?

It is no secret that tumble dryers are not especially environmentally friendly. They use quite a lot of energy and are certainly less energy efficient than hanging your washing out to dry. Several types of dryer claim to be more environmentally friendly. In particular heat pump tumble dryers …

Will energy scavenging be the next big thing? Let's stomp!

Will energy scavenging be the next big thing? Let's stomp!

The field of “energy scavenging” or “harvesting” is all about capturing the small amounts of energy that are constantly going to waste [1, 2]. Most tasks produce excess heat, light, vibrations and movement, which mostly goes to waste. A variety of innovative technologies h…

Draught proofing - how much could you save?

Posted by Alex Barrett on 14 October 2016 at 1:40 pm

Draught proofing - how much could you save?

Leaky buildings cost a lot of energy. Draughts allow hot air to escape from even the best insulated houses, and can be uncomfortable for those inside. Historic England report that older buildings lose 15-20% of their heat through draughts [1]. Fortunately this can be solved by draught proofing, w…

Are sunpipes the solution to dark rooms and stairwells?

Posted by Anna Carlini on 11 October 2016 at 10:30 am

Are sunpipes the solution to dark rooms and stairwells?

Sunpipes are cylindrical tubes which channel natural sunlight from a transparent dome on the roof to bring it to areas that wouldn’t otherwise get natural light. Many of us have dark stairwells and rooms that get little sunlight in our homes. Sunpipes (sometimes called solarpipes) are a low…

How easy is it to get a new electricity meter installed?

How easy is it to get a new electricity meter installed?

That was another saga. Firstly the letter they sent to say that my meter may be faulty gave the contact details of a third party that they had commissioned to do their meter installs. I emailed and asked for some more info. How long would the install take? Did I really need to be at home, as the …
