I’ve been reminded about indirect gadget energy use this week. I’ve blogged on this before but the article I read was a real eye opener. Here are some of the claims.
- Soon data centres will have a bigger carbon footprint than the aviation industry (and that is big).
- Bitcoin “mining” will use produce more CO2 than 1 million flights.
- Most astonishing of all. The use of the internet in Japan by 2030 may use more power than the countries current generating capacity.
There are two trends going on here. The first is that the devices we actually use are getting more efficient. The EU has pioneered this. So my new sophisticated boiler has a standby of 1W, my laptop uses less power than my old one etc. This however is being outdone by the “internet of things”. This connectivity which we are just at the start of will increase the “need” for big data. (I would question whether its desirable to have an internet connected fridge).
The second trend is more and more people are getting connected to the internet. This is great especially in the developing world but it does mean that the internets’ energy use is rising. Of course this is countered by the trend of more efficient sever centres, with companies putting them in cold places or even trying them underwater. Plus computer are getting more energy efficient.
Is there a solution to indirect gadget energy use? I’m not sure there really is. We can hold the big tech companies to account on where their power is coming from. But ultimately we need to learn to be less obsessive bout our devices.
I’ve been thinking about insect armageddon a bit over the last few days. With one of these rare very hot summers (by that I mean no rain and consistent sunny days) I have been out in the garden a lot. There has been a lot of talk of insect armageddon over the last year or so. As more flowers have come out (and due to the very long cold winter many are late) I’ve been examining the insect population. Or rather lack of it. Earlier on in the year bumblebees were out on my thistle (below) which they love.
To be fair the plant is past its best but insects there are none. Another plant they love is the sage. This year its noticeably had less flowers, but also very few bees visiting. Another herb they love is oregano. Bees and hoverflies fight over the small mauve flowers. This years visitors are almost absent although the flowers have only just come out. Encouragingly there were two honeybees on the flowers earlier. Its really rare to see a honeybee at all. Its not just bees but hoverflies, flies and the irritating midges that live in the vegetable patch and only bite you under your clothes and you don’t notice the bites for 24 hours are also in low numbers. There are very few social wasps, I have yet to to see any solitary bees or many of the more unusual social wasps or parasitic wasps. When we went to the highlands in the first week of June there were myriad insects of all sizes and types where we were staying but few elsewhere. Our car had few insects on its number plate something that has continued since and was noticeable last year.
Another strange thing is that both my neighbours had bumble bee nests along my boundary. Both have disappeared something I found in the past when I had a nest on my compost heap. Logically I would expect them to last out the whole summer.
This is all anecdotal but does suggest a drop in numbers. This has very serious implications for the natural world and for us. We need these pollinators. I’m hoping that the strange weather we went straight from winter to summer may have something to do with it and next year numbers will recover. However I fear its pollution and climate change.
People are coming up with new uses for roads apart from for driving. I heard this week of a researcher in India who is experimenting with using plastic combined with tarmac to build road surfaces. Whilst this is not a new use per se its a way of tying up carbon and also a use for waste plastic which we know is a huge problem at the moment. Apparently the waste plastic prevents potholes forming. A company in Scotland is also trying using plastic as a road surface.
I learnt today of others coming up with new uses for roads. These include embedding solar PV in them (surely relies on less traffic over time not more). Growing flowers to encourage bees and even growing crops. The short film was sold as making toilet paper. I suppose you would not want to eat food grown in the central reservation, but then I’m not sure I would want to eat honey produced by bees foraging there either. Bees are very sensitive to pollution so I suppose this is one way of indirectly measuring it. I’m not absolutely sold on with of these new uses for roads (apart from the use of waste plastic), but keep thinking people.
Are scooters a good idea? (as urban transport)? There are myriad ideas floating around at the moment about how to solve the urban transport crisis in our cities. There have been numerous cycle hire schemes with many more being reported on the way and many having fallen by the wayside. The Guardian sent its reporter out to try another idea from Paris (the Velib scheme being a Parisian one), this time electric scooters.
These are being hired out by yet another American startup company. There is a plan to pay people to charge them up at night but at the moment the company collects them at the end of each day.
Paris is awash with electric cars, bike hires, buses and of course conventional traffic. Having cycled in Paris twice. Twice being two times too many. I can honestly say I wouldn’t touch one with a bargepole. The cycling I did there was honestly one of the most dangerous things I have ever done. These things move at 15mph which I think for me is pretty fast cycling. I wouldn’t like to be hit by one at this speed or come off one. At the same time its not quite enough to outpace cars. They are allowed on the roads. You’ve got to signal and look over your shoulder etc….
I think this will go the way of the electric car hire scheme in Paris. i.e. bust. Are scooters a good idea? Take the metro or the RER. This is not the solution to urban transport pollution; walking useing public transport or cycling on segregated lanes are the solutions.
Here’s an idea I’ve not heard about before – carbon dividends. Broadly speaking polls show most Americans do believe in climate change. There is also clearly some concern amongst Republicans about Trump pulling out of Paris. They are both losing support of younger voters and if climate change is real then there could be a real crisis. Looking at the migration crisis it could be argued that its roots lie in climate change. Even if it doesn’t at present look forward to a possible climate future and it looks frightening, Added to this there is still concern about energy security. There must be some worries amongst more thoughtful Republicans that oil, gas coal and uranium are finite.
Carbon dividends combine the ideas of a carbon tax and a citizens income. Readers of this blog will know I am a huge supporter of this latter idea. The current social security model is broken in a world of part time insecure work (of which I am a part). The problem has been how to fund it. Could James Baker and George Shultz have found the solution to this conundrum and how to sell a carbon tax?
The carbon tax has been promoted by James Hansen. He talks of a tax on all carbon and vaguely of tax cuts in return. The problem is that of selling the idea. I’ve always preferred up until now a carbon ration but recognise both are a hard sell.
The Carbon dividend idea is simple. All business who pollute have to buy a fee. The money is collected and paid as a “share dividend” to all households. Imported goods and fuels are taxed to allow no home disadvantage.
The advantages are income would rise at least in the medium term.
Its simple in theory and allows markets to operate most efficiently. It does not promote any particular solution but would allow companies to choose the most effective one to reduce emissions and avoids regulation.
The idea is a citizens income in all but name (the alternative would be to build a sovereign wealth fund). However there do seem to be certainly some questions if not disadvantages. In time the income should fall even if just for peak oil reasons. Second who administrates it all? The idea is to get the government of your back but it sounds like it needs to involve the government and the tax system (in fact they do suggest this).
Its certainly an interesting idea whether its sellable anyway least of all the US at the moment remains to be seen.
The head of Scottish Power has said today that the government should drop all support foe wave and tidal energy since wind and solar are getting so cheap. Is this a case of ocean energy versus the other? This in a week after the UK government dropped its support for the Swansea bay tidal bay scheme and as solar UK output briefly overtakes gas to become number one electricity producer last Saturday.
Up until recently I would have agreed with them but thinking it through has given me pause for thought. One thing is off-shore wind. This was the most expensive mainstream renewable energy until very recently. But costs have plunged soon it will not require any subsidy. This is because it has been given consistent support and the economies of scale and the learning curve will apply. I have to agree with the government on the tidal lagoon that learning curves would not occur like nuclear each scheme would be effectively bespoke, but I think the benefits of it outwayed this. There is no doubt that if wave and tidal were given consistent support costs would plunge in the same way.
Whilst wave is the same as wind for intermittency and tends to match wind output tidal is predictable and with geographic spread would do reliable base load. In addition we are electrifying the economy and will need everything we can muster. There is only so much you can pack on to land. Ocean energy versus the other, there should be no either or.
BP moves into electric vehicles (or charging). One of the big complaints about the oil companies is that they either ignore the renewables scene, or do token amounts of it. This week BP has bought the UK’s largest electric car network. The synergy is obvious. BP owns (or mostly franchises I believe) thousands of filling stations. Western governments have all pledged to phase out carbon based transport at some point.
Its another change of direction back towards greenery for BP (following a more minor one last year). BP once called itself under Lord Brown “Beyond Petroleum”. When he went so did the last pretence of “greenwash”. The solar panels business was closed or sold. At one time it was the largest in the world. I have BP modules. BP does own some wind assets in the US but apart from that is focused almost entirely from oil. They have also however moved back into solar buying a solar park developer.
The deal will see the rolling out of 1200 rapid charging points at filling stations nationwide. These are the only practical way of dealing with charging cars at filling stations. At the moment UK sales of pure electric cars are very low. Range anxiety and the number of charging points being the reason for the slow uptake. Is this greenwash, BP hedging its bets or hard headed business decision? I think BP cannot ignore green energy. BP moves into electric vehicles, but only time will tell if this is some kind of green epiphany.
Car free days are getting more and more popular all over the world. Paris even held one in 2016. Edinburgh held one yesterday. I was at work having got there on my normal car method of cycling so took no part in it. As in other car free days the city centre was closed to cars. There were stalls, events and some kind of march involving children. The event was part of the cities transformation plan.
The aim of yesterday was to make a point about air quality and the quality of life. These are both affected by cars and road traffic in city centres. The problem is that cars are the main source of NOX and particulates. Whilst electric cars are part of the solution, solving the NOX aspect they create only a 50% reduction in particulates. This is due 50% coming from tyres, dust on the road and brakes etc.
But the quality of life is so much better if people cycle, walk and use public transport. There are indications that levels of cycling have stopped increasing. Whether the council really has the political courage to do something radical in the city centre to reduce road traffic is open to question as is what is the best way to go about it?
The latest from the BP statistical review. Its that time of year when the BP statistical review comes out. There is wealth of useful information in this annual publication. There are three things I’m going to pick out in this post.
The first thing to state is there there is more and more information in each edition. This year information about key materials for the energy transition has been added. I will be blogging on this more in the future when I’ve had more of chance to look at them.
The second thing that I noticed this year (although its been present for some years) was the comparison of gas prices in key countries. I’ve plotted all the data out below. The right hand axis shows consumption in billions of cubic feet per day (global) against the gas prices (left hand axis).
Its surprising how low gas prices are in Canada are, but its a little known fact that its a major natural gas producer. Its also worth bearing out that gas prices in the UK are still low by international comparison. Something that users in the UK don’t recognise. Global gas use is still rising relentlessly and the BP data shows only a tiny increase in proven reserves.
The last thing I’ll pick out is that global total energy consumption is still rising without any sign of a slow down. If anything its accelerating (see graph below). Obviously with many countries still developing this makes sense, but it raises a whole set of moral issues on a finite planet.
In my next blog on the latest from the BP statistical review I will look at some of the data behind this relentless energy consumption, its implications and the conclusions BP draw from it as well as some of the other information they provide.
Women won’t cycle. Or women women won’t cycle enough, that is the finding from a sustrans survey this week. The survey was carried out in a number of British cites including Edinburgh. 12% 0f women cycle at least once compared to 24% of men. As it happens I know a a number of these women and I’m married to one and the father of another! Funnily enough two of them turned up to our church homegroup on bikes last night. One had fallen off the day before as well.
The reasons why women don’t cycle are very obvious. Safety. From cars rather than attacks. These latter incidents are rare I’ve been chased three times in 30 years (once by another cyclist since I overtook him – he clearly had mental problems). All three times I easily outpaced my pursuers.
No the real problems are cars not people per say. Its not hair although there was a tendency a few years ago for most female cyclists I saw not to wear helmets, which I think must be the hair issue. This has changed and fortunately almost all cyclists in Edinburgh wear helmets (including all the ones I know). When I cycled to Paris for the Climate Conference a good proportion of us were female and they knew what they were doing and did not need any help from us men, which is as it should be.
Its clear if we have more segregated cycle lanes more people will cycle including more women.
