Following fiasco in Spain, electric car sales slump in the UK

In August it was apparent that Spain’s much-publicized plans to put thousands of electric cars on the road as part of a drive for a greener economy were way off target, with only 16 sold so far compared to the 2000 target for this year.

The Guardian reported today that

Sales of new electric cars in the UK plummeted by nearly 90% in 2009 compared with their peak in 2007, according to motoring trade association figures released this week. Just 55 of the green cars – whose fans include Boris Johnson, Jonathan Ross and Jade Jagger – were registered in 2009, in contrast to 397 in 2007, says the Society of Motor Manufacturers and Traders.

The huge fall is a blow to UK efforts to meet tough carbon emission cut targets in a decade, and comes just months before the government introduces a subsidy of up to £5,000 off new electric cars.

Nearly half of the electric vehicles sold last year were the tiny G-Wiz car. The latest modelhas a top speed of 50mph and a range of 48 miles between charges.

In January, the coalition will begin offering up to £5,000 towards the price of a series of newly launched electric cars, as part of a subsidy announced by the former Labour government. The Department for Transport (DfT) anticipates around 8,600 of the cars will be sold in the first year of the scheme. The government has so far committed £43m for the scheme to run until March 2012, with a review taking place in January 2012, but in yesterday’s spending review it talked of “supporting consumer incentives for electric and other low-emission cars throughout the life of this parliament,” suggesting the subsidy would continue after March 2012 though possibly at a lower rate.

In Spain the Industry Ministry’s plan was to have 2,000 electric cars on the road by the end of 2010 and 20,000 electric and hybrid vehicles operating the following year.

I cannot help concluding that most of these highly artificial “green” subsidies – whether for cars or for solar energy or  for wind turbines – are badly thought through, are chasing a mirage and will be counter-productive.

Coal India IPO: Coal becomes sexy again

October 23, 2010

Coal India Limited (CIL) is an Indian state-owned coal company headquartered in Kolkata, West Bengal, India and the world’s largest coal miner with revenue exceeding Rs 45,797 Cr or $10.3 billion U.S. (FY2008-09). It is owned entirely by the Union Government of India, under the administrative control of the Ministry of Coal.

As part of its divestment programme to raise about 9 Billion$, the Government of India has put up  10% of Coal India Ltd. in an IPO conducted this week. If priced at the top of its 225-245 rupee price range, the IPO would swell Government coffers by about 3.5 Billion$ and Coal India would have a market value of $35 billion, ranking it seventh among listed Indian firms. As the Economic Times puts it “The response to the Coal India (CIL) initial public offering (IPO) that finally closed early Friday morning, after lead managers were forced to extend the time limit to deal with a deluge of applications, has been phenomenal. Against the issue amount of Rs 150 billion, bids came in for Rs 2.54 trillion and the final total could be higher.
While retail investors seem to have been relatively circumspect — the retail portion was over-subscribed only 2.32 times — and employees even more so — the employee portion was not fully subscribed — both institutional and highnet-worth buyers seem to have participated with gusto.”

While a portion of the shares were held for employees the mining unions discouraged their members from applying. But with the opening price when the shares list on November 4th expected to be around Rs 300 – 320 there is a backlash among the union members who are going to have lost out. The institutional portion was oversubscribed 25 times.

Coal India has reserves of about 277 billion tonnes of which around 60 billions tonnes are currently recoverable by open cast mining. Current annual production is about 400 million tonnes and expected to rise to about 650 million tonnes in 5 years. India currently imports about 100 million tonnes of high grade coal mainly for steel making. Coal India has a major investment programme ongoing for the installation of coal washeries to improve the notoriously poor quality (high levels of abrasive ash) of Indian coals. Most Indian coals have very low values of Sulphur content so that sulphur dioxide emission is not a major concern.

The enormous interest of the institutional investors – both from within and from outside India – is a healthy indicator that simple business considerations rather than pseudo-environmentalism is still the governing factor.

Now UK joins the nuclear renaissance with 8 plants approved

October 18, 2010

The quiet nuclear renaissance continues with the UK now announcing its plans.

http://www.telegraph.co.uk/earth/energy/8070810/Eight-new-nuclear-power-stations-despite-safety-and-clean-up-concerns.html

Chris Huhne, the UK Energy Secretary, has given the go-ahead for eight new nuclear power stations in Britain despite concerns about safety and the clean-up costs.

The new nuclear power stations will be built near existing sites in in Bradwell in Essex, Hartlepool, Heysham in Lancashire, Hinkley Point in Somerset, Oldbury in South Gloucestershire, Sellafield in Cumbria, Sizewell in Suffolk and Wylfa in Anglesey.

Three sites in Dungeness in Kent and Braystones and Kirksanton in Cumbria were ruled out due to concerns over the impact on wildlife and the Lake District National Park. The new stations will not start generating power until 2018 so the Government also plans to allow existing nuclear stations to extend their life.

The government also signed a regulatory justification for the AP1000 and EPR reactor designs. Following 2004 regulations, it is required to justify that new reactors are worth the potential radiological risk. Following three consultations have taken place—one on the regulatory review, and one on each design—the government decided not to launch a further public consultation on the matter.

The AP1000 is a Westinghouse designed  1154 MWe PWR nuclear power plant. The EPR reactor is an advanced Pressurized Water Reactor (PWR) offered by AREVA and which is being built in Finland, France and China.

Purple coloured wind turbines might save some bats

October 15, 2010

Reported by the BBC:

 

purple windmill

 

A study has revealed that a wind turbine’s colour affects how many insects it attracts, shedding more light on why the turbines occasionally kill bats and birds. Scientists say that turbines, most commonly painted white or grey, draw in insects. These then lure bats and birds – as they pursue their prey – into the path of the turbine blades. Support for the idea comes from another study showing that bats are most often killed by turbines at night and in summer, when insects are most abundant.

Bats are more likely to be killed by wind turbines at night and during the summer, researchers have discovered. The reason is thought to be because the turbines attract migrating insects. At some sites, 20 to 40 bats are killed each year per turbine, although rates of one to three bats are more typical.

Now scientists have ascertained that 90% of bat mortality occurs in northern Europe between late July and early October. A similar pattern occurs in North America. Observations from both continents also show that most bats are killed on relatively warm nights with low wind speed.

While the review by scientists does not provide all the answers, it suggests wind turbines are tall enough to attract insects migrating at night, which typically fly at heights of over 60m. Bats and birds are then killed by turbine blades as they feed on this insect bonanza.

PhD student Chloe Long of Loughborough University, UK. and her Loughborough colleagues, Dr James Flint and Dr Paul Lepper, conducted the first empirical study of insect attraction to wind turbines, the results of which are published in the European Journal of Wildlife Research.

In particular, they measured how a turbine’s colour alters how many insects gather around it. Most turbines are painted pure white or light grey, in a bid to make them as visually unobtrusive as possible. But insects, it seems, are unlikely to ignore these muted tones. The researchers measured how many insects were attracted to a range of paint colours, including pure white, light and dark grey, sky blue, red and purple.

Turbines painted pure white and light grey drew the most insects bar just one other colour; yellow. The colour they found least attractive was purple.

The researchers also found that the ultraviolet and infrared components of paint colour, which humans cannot see but insects can, also had a significant impact, with higher levels of both attracting more insects.

Winning decoration for an electrical cabinet

October 12, 2010

From: http://www.byggvarlden.se/nyheter/byggprojekt/article2487490.ece

Grey is boring, thinks Fortum. Graffiti is not much better.

Therefore the Energy company organized a competition for the best decorated electrical cabinet on the street. In early October Fortum announced the winners of the “Electrical cabinet” compettion. More than 1200 contributions poured in. 180,000 people voted.

The background to the competition is that the energy company spends close to 10 million kronor every year just to get rid of graffiti.
“Now we’ll test it to see if the graffiti will diminish when thee cabinets are finer ” says Professor Molinder, adding that the contest was conducted in cooperation with the City of Stockholm.

The quiet nuclear renaissance is already under way

Commercial and planned nuclear plants around the world: Wikipedia

 

In spite of political posturing of many kinds,  nuclear power capacity worldwide is steadily increasing  with 58 reactors under construction in 15 countries. Most reactors on order or planned are in Asia, though there are plans for new units in 65 countries. In many countries which already have nuclear plants in operation significant capacity addition is being created by plant upgrading.

Quietly, the nuclear renaissance is already under way and the lead is in Asia.

The 2nd International Conference on Asian Nuclear Prospects 2010 (ANUP 2010) gets under way tomorrow at Mahabalipuram near Chennai, India.

Speaking on the occasion, chairman, Indian Atomic Energy Commission, and secretary department of atomic energy Srikumar Banerjee said that the major issue facing the sector was waste management.  R.K. Sinha, vice president, Indian Nuclear Society and director, Bhabha Atomic Research Centre, said around six new countries are interested to have atomic power plant and many of them will have one by 2030.

Of the 58 nuclear reactors currently under construction world-wide, 35 are in Asia (23 in China, 6 in Korea, 4 in India and 2 in Japan).

The Deputy Director General of the International Atomic Energy Agency (IAEA) Y.A. Sokolov said that current nuclear expansion remains centred in Asia. Of the twelve constructions started in 2009, ten were in Asia.

In addition to the new plants under construction, numerous power reactors in USA, Belgium, Sweden and Germany, for example, have had their generating capacity increased. In Switzerland, the capacity of its five reactors has been increased by 12.3%. In the USA, the Nuclear Regulatory Commission has approved 126 uprates totalling some 5600 MWe since 1977, a few of them “extended uprates” of up to 20%. Spain has had a program to add 810 MWe (11%) to its nuclear capacity through upgrading its nine reactors by up to 13%.  Some 519 MWe of the increase is already in place.  For instance, the Almarez nuclear plant is being boosted by more than 5% at a cost of US$ 50 million. Finland boosted the capacity of the original Olkiluoto plant by 29% to 1700 MWe. This plant started with two 660 MWe Swedish BWRs commissioned in 1978 and 1980. It is now licensed to operate to 2018. The Loviisa plant, with two VVER-440 (PWR) reactors, has been uprated by 90 MWe (10%). Sweden is uprating Forsmark plant by 13% (410 MWe) over 2008-10 at a cost of EUR 225 million, and Oskarshamn-3 by 21% to 1450 MWe at a cost of EUR 180 million.

Commissioner William C. Ostendorff, United States Nuclear Regulatory Commission gave the Keynote Address at  the Emerging Issues Policy Forum, Powering the Future 2010 Conference on 4th October in Florida. During his speech he said:

Despite the global financial crisis over the last two years, there still appears to be great interest in nuclear power worldwide. In September, the International Atomic Energy Agency (IAEA) released its annual nuclear power projections. In these projections, the IAEA estimates that up to 10.4% of global electricity will come from nuclear reactors by the year 2030. This estimate is higher than last year’s estimate, which was up to 9% from nuclear power by 2030. The IAEA also made projections out to the year 2050, which estimated a maximum share of 11.9% from nuclear reactors.

Since the 2008 timeframe, the number of countries interested in the introduction of nuclear power has risen from 43 to about 65. Most of these countries are in Asia and Africa. At the same time, the number of countries planning to phase out their reactors has dropped. For example, you may have read that the German government decided last month to extend the life spans of its nuclear plants while alternative energy sources are developed.

I want to touch on one more subject before I close. I believe that it is important for the public to have trust and confidence in a strong regulator. A recent report from the Organization for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) compared nuclear accident risks with those from other energy sources. What caught my attention was the impressive safety record of the nuclear industry compared to other energy sectors.

Three Gorges Dam to reach full water level this month

October 4, 2010

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town ofSandouping, located in the Yiling District of Yichang, in Hubei province, China.

Map of the location of the Three Gorges Dam, Sandouping, Yichang, Hubei Province, China and major cities along the Yangtze River

Three Gorges Dam location: Wikipedia image

The dam body was completed in 2006. Except for a ship lift, the originally planned components of theproject were completed on October 30, 2008, when the 26th generator in the shore plant began commercial operation. Each generator has a capacity of 700 MW. Six additional generators in the underground power plant are not expected to become fully operational until 2011. Coupling the dam’s 32 main generators with 2 smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will eventually reach 22,500 MW.

Xinhua reports  from Yichang, Hubei that the water level at the Three Gorges Dam, the world’s largest water control project, reached 164.59 meters on Sunday, only 10 meters short of its full capacity of 175-meters. The dam in central China started to hold back water this September by discharging less to the lower reaches of the Yangtze River, the country’s longest river.

When the water level is at its maximum of 175 metres over sea level (110 metres above the river level downstream), the dam reservoir is about 660 kilometres  in length and 1.12 kilometres  in width on average, and contains 39.3 km3 of water. The total surface area of the reservoir is 1,045 km². The reservoir flooded a total area of 632 km² of land, compared to the 1,350 km² of reservoir created by the Itaipu Dam on the border of Brazil and Paraguay (which has a  generating capacity of 14,000 MW).

Reaching the 175-meter water level would enable the Three Gorges Dam to fulfill its functions of flood control and generating electricity to the fullest extent, symbolizing the total success of the massive water project. This is the reservoir’s third attempt to reach full capacity since 2008. However, water levels stopped at 172.8 meters in 2008 and 171.43 meters in 2009 due to droughts on the lower reaches.

However, this time officials believe the dam will reach full capacity by the end of October.

Rain and lack of wind hit UK renewable generation

October 1, 2010

The Guardian reports that

The UK has suffered a second fall in renewable energy production this year, raising concern about the more than £1bn support the industry receives each year from taxpayers.

Wind turbine accident

Lower than expected wind speeds and rainfall led to a 12% fall in renewable electricity generated between April and June, compared to the same period in 2009. This setback follows a smaller but still notable decline between January and March, again compared to last year.

The DECC admits that “The intermittent nature of wind means that we do need alternative back-up generation, for when wind speeds drop” but should have added that alternative capacity is also necessary when it blows too hard and when it is too cold and when the foundations are cracking and …

Seasonal power generation can contribute marginally to energy needs but cannot provide base-load power generation.

Wind is not always as benign as it is made out. The “Summary of Wind Turbine Accident Data to 31 December 2008” reports 41 worker fatalities.

“CO2 is a valuable resource” – New Scientist

September 29, 2010
Carbon dioxide

CO2 molecule

Greenhouses to negate greenhouse effects?

The New Scientist today saysCarbon dioxide may be bad for the climate, but it’s good for the roses. Perhaps it’s time we rehabilitated this gaseous villain”.

While plenty of commercial greenhouses top up their air with extra CO2, what is unusual about this one is where its CO2 comes from. Until a few years ago, the greenhouse’s operators used to burn natural gas for the sole purpose of generating CO2. Today it is piped from a nearby oil refinery. Each year, 400,000 tonnes of CO2 are captured and then piped to around 500 greenhouses between Rotterdam and The Hague, where it is absorbed by the growing plants before they are shipped for sale around the world .

“It’s time we stopped thinking of CO2 solely as a pollutant and viewed it as a valuable resource,” says Gabriele Centi, a chemist at the University of Messina, Italy.

Cash for carbon

Capturing carbon dioxide from smokestacks and then pumping it underground is going to be an expensive way to combat climate change. For a coal-fired power plant, for instance, the process is expected to add 30 per cent to the cost of generating electricity. However, a handful of entrepreneurs are already beginning to turn a costly waste product into a valuable commodity.

Wikipedia

Take some flower-growing greenhouses in the Netherlands. There, CO2 emitted from a nearby oil refinery is piped to the plants, boosting their growth (pictured, and see main story). The scheme began in 2005, when Organic Carbon Dioxide for Assimilation of Plants (OCAP), a newly formed gas supplier, began pumping waste CO2from the refinery to the greenhouses along a disused oil pipeline. The refinery sells the CO2 to OCAP at a profit, which then sells the gas to greenhouses at a price lower than what they were paying to burn natural gas to generate CO2. “I think the best way to fight climate change is making money out of it, otherwise our efforts wouldn’t survive in the long term,” says OCAP director Hendrik de Wit.

A ramble through electricity consumption and aspirations.

September 29, 2010

From the IEA 2010 World Energy Statistics, the country with the lowest electricity consumption is Haiti at 23 kWh /capita. The country with the highest consumption is Iceland with 49,818 kWh/capita. In between come Ethiopia at 42 kWh/capita, Kenya at 156, India at 566, Iraq at 1267, China at 2453, France at 7,703, the US at 13,647, Canada at 17,053 and Norway at 24,868 kWh/capita. For the world as a whole the average consumption is 2,782 kWh/capita.

The average is 18 times less than the maximum and the minimum is 120 times less than the average. And of course the average in every country itself represents an enormous spread between individuals.

To put this into the perspective of living standards and the quality of life, the electricity consumption of household goods is typically as follows:

  • One 60 W light –bulb for 8 hrs per day consumes 175 kWh/annum,
  • Typical 19” colour TV (70 W) for c. 5 hrs per day 125 kWh/annum
  • Table fan (20 W) for c. 12 hours per day 88 kWh/annum
  • Desktop computer (100 W) for 8 hours per day 290 kWh/annum
  • Refrigerator (80 W), continuously, 700 kWh/annum
  • Freezer 150 W continuously, 1300 kWh/annum

To have access to one 60 W light bulb when you have none is an enormous improvement in the quality of one’s life. To have access to a fridge so that shopping and cooking every day while also holding down a full-time job is no longer necessary is the difference between freedom and slavery for many women in the developing world. It is a sobering thought that if every Haitian used just one 60 W light bulb for 8 hours every day, the electricity consumption in Haiti (and therefore electricity generation) would increase seven-fold!
