If I were Minister of Energy

With a post title like this, it is probably worth pointing out that Theresa May scrapped the Department Of Energy and Climate Change in July and it became the Department for Business, Energy and Industrial Strategy.

Just read that new department title again......slowly.......it is FOR business and energy. And the energy that they are FOR is more energy consumption to profit the Big Six energy suppliers, along with Fracking. Not FOR the energy efficiency measures that reduce consumption and fuel poverty, or make our industry more efficient and competitive. Climate Change has been completely dropped from the title, along with any pretence that this government gives a damn about reducing carbon emissions.

"The Department of Energy & Climate Change (DECC) works to make sure the UK has secure, clean, affordable energy supplies and promote international action to mitigate climate change."

The old mission statement replaced with.....

"The department brings together responsibilities for business, industrial strategy, science, innovation, energy, and climate change."

So there is no Minister for Energy and Climate Change in the UK, but if there was one, that was not tied in to business and industry growth targets, there really are plenty of things that they could do to reduce carbon emissions.

One of the cost effective measures to reduce energy would be to send the office workers home. If one person in the office works from home, they will still use energy for their technology at home and in winter some lighting and heating. However they will not be commuting and in summer it is most likely that their home will not have cooling (we don't tend to in UK homes) and the lights wont be on continuously.

Technology has come so far that we can work anywhere. There is really no need to have a separate 'office' to work in when documents can be stored on the cloud, conversations held on skype or facetime and work carried out on 'pocket-sized' portable devices. Wouldn't you rather work from a park bench or sat on the promenade in summer, than in a stuffy office space?

Now if all the workers in the office worked from home the benefits increase dramatically. That company may no longer need to lease a building or maybe just a smaller building that contains meeting rooms and hotdesks, but no permanent desk spaces. Instantly there are less corridors and toilets being lit all day, besides the massive saving in cooling and ventilating many of these densely packed office spaces, so a big energy saving.

Additional carbon savings would be from the reduction in traffic congestion - if you only had to go in to work for a meeting once a week, you would probably avoid first thing Monday morning, right. Traffic congestion is an appalling waste of energy, engines running whilst going nowhere, and a significant contributor to air pollution. Reducing the number of commuters will ease the situation for the people who can't work from home, like nurses, retail workers, police officers and politicians. And of course you could always hold your weekly meeting in your local coffee shop or curry house, which would benefit small businesses outside of the central district.

There is also a community benefit as it would bring more able-bodied adults back into communities during the day, making them a safer place for the elderly. Not to mention how many hours a week extra you could spend with your family or friends if you are not commuting. There are a whole host of other benefits, such as reductions in absenteeism, improved mental health, better work-life balance etc. but you get my point.

And if you think that you can't send people home because they won't get any work done, then you are soooo wrong. Trust me on this. I thought that I am getting a bit slow with work and not as efficient as I used to be, after 8 years working from home, but once I stepped back into an office environment I was vindicated. It is far more distracting working with other people. You are obliged to ask them how they are, get distracted by other peoples phone calls, then discuss any query/decision/irritation/success with everyone, just because they are there. At home you get distracted hanging the washing out or walking the dog, but in between you get to concentrate. There is also the incentive that if you finish all your work quickly you are free to relax, instead of watching the clock until home time.

And if you think you may miss the social aspect, just ask yourself if you have any genuine friends at work? If you do you will stay in touch, but chances are there are a good few people that you would happily not sit next to every day. Do you get up to speak to the people in the office next door or just email them? I rest my case!

It would be a win for the government because less investment would be needed on infrastructure if the roads are slightly emptier, and reductions in carbon emissions and air pollution would help meet some of our legal reduction targets. They could also see significant savings by sending government workers home. The demand for new office buildings would drop, and government support for converting them to dwellings, would help landlords to re-coup their losses and give a good opportunity to require energy efficiency improvements, along with easing the housing shortage.

This is really a biggie and is the next logical step given the way technologies are heading. It is the kind of solution the government likes because it doesn't cost them very much, just a bit of change management required. All it needs is some dynamic companies to demonstrate the potential for reducing their overheads or a Minister of Energy to promote the change! Please feel free to nominate me for that role ;-)

Un-seasonal



Blue sky makes all the difference
The sky was blue today after yet another storm hit the UK. This was the 9th storm this winter which is more than the average.

Rain approaching
Storms in the UK are certainly not international news, no twisters or snowmaggedons. Just rather dull and continuous rain, accompanied by howling winds. There hasn't even been thunder and lightening to add some excitement. Some areas have experienced flooding or downed power lines, yet it is theunusual pattern of weather that makes it news-worthy for me.

Very wet and muddy dog walks
It is an El Nino year, which has spread a mixed bag of extreme weather across the world. Even so, I can't just shrug it off and expect next year to be 'normal' again. Have we had a 'normal' year in the last decade? A year when rainfall or temperature  records haven't been broken?

I wish rainbows were the only thing coming from this coal-fired power station.
The climate change predictions for the UK (that I read a good few years ago now), indicated that winters would be milder and wetter, with much less frequency of snow. Summers would also be milder and wetter, except for in the Southeast. This describes 2015 pretty well. Last summer was warm, but can anybody remember a day that was actually hot, like sunbathing-on-the-beach hot? We kept wondering when summer would start. And this winter has been exceptionally mild so far, though very wet and stormy.

Are we moving to a 'season-less' climate in the UK, with far less definition between spring and summer or autumn and winter? That is not to say that every year will be like that, just that a trend may be emerging. I mean we can't expect to ignore all the danger signs about climate change and not have to face the consequences.

Lovely traditional stone terraced housing
The good news is that buildings in the UK are built to withstand this kind of weather, at least most of the dwellings are. The majority of dwellings are built of brick or stone, and feel solid and secure whilst the wind is howling round them. The style is for low-rise, compact and often terraced dwellings. Even hurricane strength winds only result in a few chimney pots being toppled, trees falling and power lines being damaged. Watch the scenes in other areas of the world and whole streets of homes get reduced to matchsticks.
Old brick built factory still looking amazing
This is also why we have some of the oldest housing stock - brick houses are expensive and slow to build (compared to timber) and as they last well and are expensive to replace, we keep them. Even more so with stone dwellings. My friend's cottage is over 300 years old, and the thick stone walls would have taken an enormous amount of energy to demolish.

Any excuse for more nice photos
Now I know that old houses get a bad name for not being energy efficient, but that is not entirely true. They tend to be small, so have less volume to heat, and if they are terraced they reduce heat loss by having less external wall area. Houses were built with good natural light in all rooms, before we had electricity and had a cellar and a pantry instead of a fridge or freezer.
 

That is not to say that older buildings don't feel cold and draughty, but it is worth bearing in mind that a new efficient double-glazed window provides no more insulation than an old solid brick wall. Modern buildings with vast glazed areas are really not a great idea if you wish to reduce your heating bills. You will find that there is more focus on building houses airtight these days, to reduce unwanted draughts, and adding additional insulation to any building will always improve the thermal comfort and efficiency.
Survived since 1483
Other bloggers have noticed changes in their weather patterns too, sometimes major scary events like the forest fires and drought in Tasmania that Jo mentioned, or even small signs of change such as still picking raspberries in November as Mrs Thrift noted. I would love to hear of any changes that you may have noticed, wherever you are. It may be plants flowering earlier or areas flooding that have never been flooded before. It all helps to build up a picture of how the climate is changing and prepare us for what might come next.

The Obelisk

Who knew that Loughborough had an Obelisk? Loughborough isn't London by a long shot, it is a small town in the Midlands and yet poking above the treeline on the outskirts of town there is an 80ft Obelisk.


When I first saw it I thought maybe it was a chimney from an old factory or brick works, but given its location it made no sense.

 
 
It was built in 1730 for Ambrose Phillips who owned the Garendon Estate. He had been inspired by a trip to Italy. You can find out more history here. Garendon Hall was in a poor state after the war and was demolished, and the rubble used in the building of the M1 motorway. The Garendon estate is slowly disappearing as chunks have been sold off to developers over the years. My home is built on former Garendon estate land and we are fighting to stop the remaining land being developed.


How many 285 year old Obelisks involve traipsing through a muddy woods to see them? It looked rather lonely and neglected, and has had some ugly repair work. But the four spheres that hold the column up still look amazing. It was hard to get a good photo to show it on my mobile, but the whole top column rests solely on these stone spheres, giving the illusion that it could roll off, yet it is clearly incredibly stable.

What is reassuring is how well it has been built, considering it was before the industrial revolution and well before we had discovered oil. There is lots of amazing architecture still standing from this time, but I can't imagine the brickwork on my house surviving more than 100 years!

It is easy to forget how brief the current era of cheap oil has been. Where will the downward slope of the oil peak take us? Maybe it will re-ignite an interest in sailing ships, canals, windmills and great architecture again. Or maybe something completely different. But I think it highly unlikely that it will take us back to a medieval Britain, although many (my kids included) seem to imagine that this is what life without the internet means. Before oil there were books, music and art and after the oil is gone there will be too.

Ashby Castle and Resilience

It has been the summer holidays and we have had our share of nice days out. Last week I visited Ashby Castle with my youngest daughter and her friends. You may be able to make them out at the top of the tower.

 
Ashby Castle is an English Heritage site. It is basically a ruin, but what remains is immensely fun for kids. There are the grassy slopes of a sunken garden and lake, which are great for rolling down or running around.


There are ruins with grand doorways and hidden stairways, brilliant for hide and seek or toy sword battles. The 6 storey tower with it's spiral staircase gives a grand view of the surrounding area too.


But absolutely the best feature is a secret underground passageway running from the base of the tower to the old kitchen cellars. It just gives an extra element of authenticity and fun to imaginative battle games to storm the castle.

 
Now some of the visitors will be wandering round with an audio guide, but we just spread out a picnic and let the kids imaginations run wild.

When my youngest daughter was about 2, we came with some friends - about 13 kids in total. The boys were all dressed up as knights and kings with swords and shields, and the younger girls as princesses. It was the most amazing day! It is such a shame that they have grown up.


This time was a much quieter affair and I sat looking at the walls of the tower. They are incredibly thick. The wall above is twice as thick as the doorway.


The tower was built in 1470 and designed to withstand attacks. The thick walls were a big investment of labour and resources, but the intention was to build something that was resilient and would last for generations. As it was, the tower was blown up in 1648, but it was so well built that the remaining half of the tower that you see above, has stood for another 360 years and could well last another 360 more.

I was sitting on a picnic blanket reading a section from Green Wizardry by John Michael Greer on 'Sustainability and Resilience'. His point was that efficiency is about getting the most from the least resources, whereas resilience is the opposite. Resilience is about having spare capacity or using extra resources to make things that are stronger, longer lasting, and can absorb shocks. In the case of Ashby Castle the time, energy and resources invested in those strong walls, was intended to protect the people inside and is the main reason that they are still standing for us to enjoy today.


Here is an example of some homes built in the last couple of years. To me they are so ugly. But they are very efficient. Look at the shape - they are almost square. This gives the biggest internal area for the smallest area of external walls. In other words it uses less bricks than a fancier shaped house. The ceilings inside are low to reduce unnecessary height and brickwork. And the roof has virtually no overhang to save on tiles, which would otherwise provide some shelter from rain to the brickwork and shade upper windows in hot weather. It is also a very shallow roof slope, again being efficient with materials, but not allowing for any deviation in the weather that could bring a heavy snowfall.

The buildings are 3 storeys high to minimise on the footprint, and in addition the garden is tiny, so being very efficient with land. Just in case you don't realise how short the garden is, I was walking along the path one day, when the occupant opened their back door and threw a burnt slice of toast over the back fence. Just a toast toss between backdoor and fence!

 
 
There was really no need to be so efficient with space in Loughborough. This is the edge of a small town, not a city centre, but then maybe it is better to squeeze all the ugly buildings in tightly so as not to spoil the view too much.

The council negotiated an 11 acre open park area as part of the development deal, which is great for me to walk my dog round, but it adjoins an existing park area of a similar size, and it is not widely known about. So these ugly houses have been built with virtually no space to grow their own food, dry their washing, or room for their kids play. Yet the open playing areas are too far from the houses and too empty of people to be safe from stranger danger, so it seems the kids stay at home instead.

There is no large lawn to mow for weekly exercise, or flowerbeds to attract bees and insects. No room for trees or ponds to encourage wildlife and back garden ecosystems. Yet the council, with their funds becoming tighter, now has the burden of an additional large open space with grass to cut, bins to empty and borders to maintain on a regular basis. There are no allotments in this ward either!

The really wasteful thing is that these houses probably won't be here at the turn of the next century, so it is a false sense of efficiency. It is not just because they seem flimsy compared to a large part of the UK's building stock which is built pre-1940. But because they are ugly, and who wants to maintain and care for an ugly house?

The homes below are cheap and cheerful houses from 100 years ago. Efficient terraced housing with small gardens. They were built to save space and be close to amenities, as people walked most places in those days. However the little attractive features, such as the decorative trim at the eaves, the curves around the windows and doors, and the symmetry all add to making them more appealing and helping them survive. The rooms have additional height to make them feel more spacious and the bay window makes them feel less 'square' and brings in more light. They may not have un underground tunnel, but were built with cellars.


It is funny because even the 1950's council houses were solid and built to last, and they provided a reasonable garden. During a time when the country had a large war debt to pay off we were building with some resilience. At some point since then resilience has gone out the window. There is clearly a lack of balance between 'lean manufacturing' efficiency (otherwise known as cheap and cheerful 'Noddy' homes) and a need to build in resilience so that homes are fit for the future.
