The Clean Energy Bill has been on the agenda for some time and not just in the UK. With climate change an ever growing global concern, investment in other cleaner energy sources has been essential. However, when it comes to investment in wind farms, developers have faced significant opposition. The balancing act for the government appears to be generating sufficient investment in wind farms, while minimising the negative externalities.

The phrase often thrown around with regards to wind farms, seems to be ‘not in my backyard’. That is, people recognise the need for them, but don’t want them to be built in the local areas. The reason is to do with the negative externalities. Not only are the wind farms several metres high and wide, creating a blight on the landscape, but they also create a noise, both of which impose a third party effect on the local communities. These factors, amongst others, have led to numerous protests whenever a new wind farm is suggested. The problem has been that with such challenging targets for energy, wind farms are essential and thus government regulation has been able to over-ride the protests of local communities.

However, planning guidance in the UK will now be changed to give local opposition the ability to override national energy targets. In some sense, more weight is being given to the negative externalities associated with a new wind farm. This doesn’t mean that the government is unwilling to let investment in wind farms stop. Instead, incentives are being used to try to encourage local communities to accept new wind farms. While acknowledging the existence of negative externalities, the government is perhaps trying to put a value on them. The benefits offered to local communities by developers will increase by a factor of five, thus aiming to compensate those affected accordingly. Unsurprisingly, there have been mixed opinions, summed up by Maria McCaffery, the Chief Executive of trade association RenewableUK:

Maria McCaffery, chief executive of trade association RenewableUK, said the proposals would signal the end of many planned developments and that was “disappointing”.

Developing wind farms requires a significant amount of investment to be made upfront. Adding to this cost, by following the government’s advice that we should pay substantially more into community funds for future projects, will unfortunately make some planned wind energy developments uneconomic in England.

That said, we recognise the need to ensure good practice across the industry and will continue to work with government and local authorities to benefit communities right across the country which are hosting our clean energy future.

The improved benefits package by the energy industry is expected to be in place towards the end of the year. The idea is that with greater use of wind farms, energy bills can be subsidised, thereby reducing the cost of living. Investment in wind farms (on-shore and off-shore) is essential. Current energy sources are non-renewable and as such new energy sources must be developed. However, many are focused on the short term cost and not the long term benefit that such investment will bring. The public appears to be in favour of investment in new energy sources, especially with the prospect of subsidised energy bills – but this positive outlook soon turns into protest when the developers pick ‘your back yard’ as the next site. The following articles consider this issue.

Questions

  1. What are the negative externalities associated with wind farms?
  2. Conduct a cost-benefit analysis as to whether a wind farm should be constructed in your local area. Which factors have you given greatest weight to?
  3. In question 2 above, were you concerned about the Pareto criterion or the Hicks-Kaldor criterion?
  4. If local communities can be compensated sufficiently, should wind farms go ahead?
  5. If the added cost to the development of wind farms means that some will no longer go ahead, is this efficient?
  6. Why is there a need to invest in new energy sources?
  7. To what extent is climate change a global problem requiring international (and not national) solution?

Much has been written on Margaret Thatcher following her death at the age of 87 on April 8. But getting a calm assessment of both her time in office and her legacy is not easy. And it’s clear why: she created both stronger loyalty and stronger opposition than any other UK Prime Minister.

As economists, however, we should try to be as dispassionate as possible in assessing the effects of policies. There is always a normative question of the relative desirability of different economic outcomes – and you will have your own views on the relative importance of objectives such as economic growth, greater equality and greater social cohesion – but to determine cause and effect, or at least correlation, requires a careful examination of the evidence. Also, drawing lessons for future policy requires a careful modelling of the economy and the effects of changing economic variables.

The following articles have been selected from the hundreds that have appeared in the press in the past few days. Whilst they cannot be claimed to be totally ‘objective’, taken together they give a good overview of her economic policies and her economic legacy.

You may well have been surprised by the amount of coverage of her death and at the fervour of her supporters and critics. But this bears witness to the huge effect she had on both the political scene and on the UK economy – for good or bad.

The UK government has just given the go-ahead for the building of two new nuclear reactors at Hinkley Point in Somerset. The contract to build and run the power station will go to EDF, the French energy company.

The power station is estimated to cost some £14 billion to build. It would produce around 7% of the UK’s electricity. Currently the 16 nuclear reactors in the UK produce around 19%. But all except for Sizewell B in Suffolk are due to close by 2023, although the lives of some could be extended. There is thus a considerable energy gap to fill in the coming years.

Several new nuclear power stations were being considered to help fill this gap, but with rising capital costs, especially following the Fukushima disaster in Japan, potential investors pulled out of other negotiations. Hinkley Point is the only proposal left. It’s not surprising that the government wants it to go ahead.

All that remains to agree is the price that EDF can charge for the electricity generated from the power station. This price, known as the ‘strike price’, is a government-guaranteed price over the long term. EDF is seeking a 40-year deal. Some low carbon power stations, such as nuclear and offshore wind and wave power stations, have high capital costs. The idea of the strike price is to reduce the risks of the investment and make it easier for energy companies to estimate the likely return on capital.

But the strike price, which will probably be agreed at around £95 per megawatt hour (MWh), is roughly double the current wholesale price of electricity. EDF want a price of around £100 per MWh, which is estimated to give a return on capital of around 10%. The government was hoping to agree on a price nearer to £80 per MWh. Either way, this will require a huge future subsidy on the electricity generated from the plant.

There are several questions being asked about the deal. Is the strike price worth paying? Are all the costs and benefits properly accounted for, including environmental costs and benefits and safety issues? Being an extremely long-term project, are uncertainties over costs, performance of the plant, future market prices for electricity and the costs of alternative forms of power generation sufficiently accounted for? Will the strike price contravene EU competition law? Is the timescale for construction realistic and what would be the consequences of delays? The articles consider these questions and raise a number of issues in planning very long-term capital projects.

From early January to late February 2013, the average pump price of petrol in the UK rose by over 6p per litre – a rise of 4.7% in just seven weeks. There have also been substantial rises in the price of diesel.

The higher prices reflect a rise in the dollar wholesale price of oil and a depreciation in the pound. From 2 January to 21 February the pound fell from $1.63 to $1.53 – a depreciation of 6.1% (see). Crude oil prices (in dollars) rose by just under 7% over this period. With oil imports priced in dollars, a weaker pound pushes up the price of oil in the UK. The price has then been pushed up even higher by speculation, fuelled by the belief that prices have further to rise.

The higher price of road fuel, plus the general squeeze on living standards from the recession, with prices rising faster than wages, has caused a reduction in the consumption of road fuel. Petrol sales have fallen to their lowest level for 23 years. Sales in January 2013 were 99m litres down on the previous month’s sales of 1564m litres (a fall of 6.3%).

Not surprisingly motorists’ groups have called for a reduction in fuel taxes to ease the burden on motorists. They also argue that this will help to drive recovery in the economy by leaving people with more money in their pockets.

Equally not surprisingly, those concerned about the environment have welcomed the reduction in traffic, as have some motorists who like the quieter roads, allowing journey times to be cut, with resulting reductions in fuel consumption per mile.

The following videos and articles discuss the causes of the most recent fuel price rises and also examine the responsiveness of demand to these higher prices and to the reductions in real incomes.

It’s a relatively common dish to see on a menu at a restaurant: mackerel. This particular fish has been promoted as a healthy and sustainable dish, but now its sustainability is coming into question and the Marine Conservation Society has taken it off its ‘fish to eat’ list. My brother Hugh is a marine biologist and often comments on which fish we should be avoiding due to sustainability issues (especially given how much I like fish!) So, how is this an economics issue?

There a couple of key things to pick out here. Firstly, with the conservationists’ warning of this issue of unsustainability, they have been asking consumers to reduce the amount of mackerel they buy. This will naturally have an impact on fisherman. If consumers do listen to the conservationists and hence reduce their demand for mackerel, we could see a fall in the price of this fish and a reduction in the fishermen’s turnover. It could be that we see a switch in consumption to other more sustainable fish, especially if we see some form of intervention.

Another area concerning economics is the idea of over-fishing. For years, there have been disputes over who has the rights to these fish stocks. In the past, the Faroe Isles and Iceland have increased their quotas significantly, as mackerel appear to have migrated to their shores, contributing to this question of sustainability. Iceland and the Faroe Isles have ‘unilaterally agreed their quotas … as they are not governed by the common fisheries policy’.

The question is: when fisherman catch one additional mackerel, what are they considering? Do they think about the private benefit to them (or their company) or do they consider the external cost imposed on others? Whenever one fish is taken from the sea, there is one less fish available for other fishermen.

This leads to over-consumption of fish and contributes towards the well-documented depletion of fish stocks and ‘The Tragedy of the Commons’, if account is not taken of the external cost imposed on other fishermen.

The total catch is now far in excess of what has been scientifically recommended and previously agreed upon by all participating countries. Negotiations to introduce new catch allowances have so far failed to reach agreement.

There are hopes that an international policy on quotas can be agreed to ensure mackerel levels return to or remain at a sustainable level. However, at present no progress has been made. Until some form of an agreement is reached, fishermen around Iceland and the Faroe Isles will continue to battle against the conservationists. The following articles consider this fishy topic.

Questions

  1. Why are quotas set by the EU for fishing? Who do they apply to?
  2. Why is there an externality from fishing?
  3. What is the Tragedy of the Commons? Using a diagram with average and marginal revenue product and average and marginal cost illustrate the market equilibrium and the social optimum. Why are they different?
  4. Following on from question 3, what does this suggest about the role of governments?
  5. If the conservationists’ request regarding buying less mackerel is successful, what impact might this have on fishermen and fisheries?
  6. If consumers do switch to buying other fish, what would happen to the equilibrium in the mackerel market and in the market for other fish? Think about this question in terms of general equilibrium analysis.
