Britain claims to lead the world in tackling climate change. But in reality, the UK's attempts reduce carbon dependency are feeble. With energy costs so cheap, the answer may be in all our hands, writes Chris Goodall.

A raft of schemes has failed to cut UK greenhouse-gas emissions over the last decade. Carbon dioxide (CO2) output has risen by 4% since 1997, or over 8% if emissions from international travel are included. Independent forecasts of energy use continue to see substantial rises.

The National Grid, which is responsible for operating the UK’s main electricity and gas supply networks, is preparing for a 5% growth in electricity use over the next six years; it also predicts gas consumption will increase by over twice as much.

Government ministers and company bosses are not lying when they claim to have introduced measures to arrest the growth in energy use. By and large, these people really do mean what they say. Most chief executives, trained to recognise long-term trends, openly acknowledge that climate change is a huge threat and have taken limited measures to cut emissions. Government departments, weak and disorganised though they often seem, are throwing money at hundreds of research programmes, grant schemes and marketing campaigns to help us all reduce energy use.

But it simply isn't working, and there is one principal reason: fossil fuel energy is extraordinarily cheap, both in historical terms and when measured against average salaries. Consider the tumble dryer. A full load of clothes, swiftly extracted from the washing machine and pushed firmly into the dryer, can be painlessly dried in a couple of hours or less. To take that tangled mess of dripping underwear, shirts and tea towels and pin it on a washing line might take 15 minutes. Drying “by hand” would take several hours, possibly a day, and bringing the clothes indoors and folding them could easily take another 20 minutes. Moreover, rain could fall or the activities of birds could spoil your clean sheets.

However, the cost of the electricity to power the dryer will be around 25 pence (US$0.50), and the labour saved may be half an hour or more. As a result, the rational person who values his or her own time has little choice. Homo economicus slams the door of the dryer shut, feeling only a little guilty that another kilogram of CO2 has been added to the communal atmosphere.

The financial incentive to restrain household energy consumption is small. Take lighting as an example. The average UK home uses around 750 kilowatt hours each year, costing around £65 (US$128), or the price of a family evening out. Does it make sense to buy energy efficient bulbs? The average house has about 25 light fittings and many middle class homes have twice that number. These fittings come in all different sizes and shapes, and to replace your old fashioned incandescent bulbs with low energy equivalents is time-consuming and expensive. Moreover, you might not even find a direct replacement; there are over 100 different types of bulb sold in the UK, and even Tesco, a major supermarket chain, only sells nine energy-efficient equivalents. You may up spending around £100 (US$197) in order to save about £45 (US$89) a year in lower electricity bills. To most people, it is simply not worth the effort.

What about the surreptitious dash to the supermarket in the car? You may know you should cycle, but there is something good on TV and the three-mile round trip probably costs about 40 pence (US$0.89) in petrol, or less if you have got an efficient new diesel car. It saves you 20 minutes on a bike and although the parking is a bit difficult, you get back before the TV programme started. You spend £15 (US$30) on groceries, and the petrol cost is scarcely noticeable.

The cost of gas for central heating is higher than it was a couple of years ago. Nevertheless, little by little, we are increasing the internal temperatures of our houses. A decade ago, we thought 18 degrees centigrade was warm, now the typical thermostat is set at 20 or more. The extra cost of this comforting warmth in winter is less than £100 ($US197), but the change added a tonne of CO2 a year.

What about turning the computer off? Leaving it on overnight probably adds about 16pence (US$0.31) to your employer's electricity costs. It might take five minutes to turn on again, and to open the programmes you need. What sort of employer values someone as able as you at 16 pence for five minutes? After all, even the UK minimum wage pays three times as much for this length of time. It may even be financially irresponsible to use the off switch before going home.

At the other end of the spectrum, think about the humble soft-drink can. Today, it will almost certainly be made from aluminium, a metal that needs enormous amounts of energy to make. One small can of cola contains some flavoured water and a kilowatt hour of energy. Recycling this can saves most of this energy. Does this make it worth collecting and re-processing? Make your own mind up – the price paid by aluminium recyclers in the UK is 45 pence (US$0.89) for 60 cans.

As growth has made people richer, energy has got cheaper and cheaper in relative terms. For people with a decent income and multiple demands on their attention it is increasingly sensible to use electricity to save effort, or petrol to avoid wasting time. We will not get to grips with climate change until we recognise this.

Governments persist with policies that stand no chance of combating the insidious addiction to energy that is – to all intents and purposes – free. In the host of schemes that the UK government has introduced, there is no recognition of the underlying problem that energy is too cheap for people to want to ration its use. Frightened by the possible electoral reaction to any attempt to increase fuel and power prices, the UK government has substituted poorly funded programmes and exhortatory press releases for real action.

政策和制度的重要性

大众需要环保的意识!但是,正确和合理的政策和制度是确认大众对环保有所行动的保证。文章中举的英国人的例子非常有说服力!!很好!

The importance of policies and schemes

The masses need to be environment-conscious. However, valid policies and appropirate schemes are crucial to the needed action taken by the public. The UK as mentioned in the article is a well-illustrated example.


疑问

现在发达国家的NGO都来发展中国家开展项目,保护环境,但是他们自己都做好了吗?发达国家的人们依然消耗大量的资源,他们依然开车坐飞机,我有时很困惑,他们想说服还吃不饱饭的发展中国家减排,其资格何在?

Queries

Nowadays, those NGO in developed countries are launching environmental protection events in developing countries; However, have they done their job in their own countries? Those in developed countries are continuing consuming a large amount of resources, they are driving and travelling by plane.

So I feel confused sometimes, and wonder if they are eligible to persuade China, a developing country where people are still struggling for food, to cut emissions?


就用干衣机好了!

大部分人都愿用简便的方式干事情,我也不例外.我并不介意去计算启动干手机要产生多少二氧化碳了.如果非要我计算一下的话,我可能连挂衣服,然后走开...整个过程我呼出的二氧化碳都算上,看看用干衣机到底值不值.可是我懒得这样算,就只管用它好了.

I will choose the dryer!

Most people will choose a easy way to finish a work, so do I. I will not bother calculating how much CO2 will be generated by turning on the dryer. If I have to do so, I might also like to calculate how much CO2 will be generated by supporting me to finish hanging, walking and so on, and see if it is worth turning on dryer or not. But I am too lazy to do that, and then I choose the dryer.


代价将会是什么?

如果出现一场像战争一样一目了然的危机,人们定会认识到生活的这个世界发生了多巨大的变化,因为他们可以切实地感知到问题的所在.然而对于气候变迁,我们却很难察觉,当气候随着日积月累发生了明显的实质性变化时,我们即便能发现也已为时过晚.我认为,我们有义务让世人清楚地了解我们的孩子们将生活在一个什么样的世界里,并让大家意识到这是一个道德问题.大多数人都不会赞成向孩子们掠盗的做法,可是我们如果做了错误的选择,自私和懒惰的背后,我们是在掠夺子代们的资源.我们每多将一公吨的碳资源释放到大气中,都意味着下一代又减损了一公吨碳资源.无论我们的父母为我们做什么,他们都清楚事情的后果,我们也当如此不是吗?

So what does it take?

If there was a real visible emergency -- like a war -- people would accept huge changes in the way they lived because they would see the point. The difficulty with climate change is that by the time it becomes a visible, tangible emergency for most of us, enough for us to understand the danger we are in, it will be too late. I think we have to make people understand exactly what kind of world today's children will have to live in and show them that this is a moral issue. Most people would not think that stealing from a baby was a good thing. But if you make the wrong choices, through selfishness and laziness, you are stealing from children. Every tonne of carbon we put into the atmosphere is a tonne less for the next generation. When our parents did it to us, they did not know the consequences. We do.

英国政府可采用超临界锅炉来替代长期使用的燃煤锅炉发电,这在削减CO2排放量上是一重大进步。因为这能削减20%的CO2排放量,这么大的量,比我们晾干衣物省下的CO2还要多。这样,英国政府就可以追随中国的步伐:中国有世界上80%的超临界压力锅炉发电站,而将来新建的发电站也将使用该技术。

Mr

One huge step the UK could take to reduce emissions is to retro-fit supercritical boilers to its longer life coal fired power stations. this would cut CO2 emissions by 20% at each of these - a huge amount and much more than savings gained by people putting their washing out to dry. In this way the UK would be following in China's footsteps: China has 80% of the supercritical coal stations installed in the world and most of its new stations will use this technology in the future.
