Opinion of the European Economic and Social Committee on the Current situation and prospects for traditional energy sources — coal, oil and natural gas — in a future energy mix

(2006/C 28/02)

On 10 February 2005, the European Economic and Social Committee, acting under Rule 29(2) of its Rules of Procedure, decided to draw up an opinion on the Current situation and prospects for traditional energy sources — coal, oil and natural gas — in a future energy mix.

Current situation and prospects for traditional energy sources — coal, oil and natural gas — in a future energy mix

The Section for Transport, Energy, Infrastructure and the Information Society, which was responsible for preparing the Committee's work on the subject, adopted its opinion 1 September 2005. The rapporteur was Mr Wolf.

At its 421st plenary session, held on 26-27 October (meeting of 26 October 2005), the European Economic and Social Committee adopted the following opinion by 119 votes to 1, with 3 abstentions.

The EESC has recently adopted a number of opinions (1) on energy issues. Since by far the largest share of energy supply still comes from the fossil fuels: coal, oil and natural gas, and the question of resources and the release of greenhouse gases associated with their use has been the subject of political discussion, the present opinion evaluates these ‘classic’ fuels.

1

The strategic aim of this series of opinions, which an opinion on renewable energy sources and the present opinion bring to a conclusion, is to provide a solid basis for establishing realistic options for a future energy mix.

This should be followed by an opinion on ‘The EU's Energy Supply: Strategy for an Optimum Energy mix’ which builds on and summarises the findings of the series.

| 1.1 | Usable energy is the mainstay of our contemporary way of life and culture. It is only its ready availability that has made our present standard of living possible. If the Lisbon Strategy and the Gothenburg and Barcelona Council conclusions are to be implemented, a secure, cheap, environmentally-friendly and sustainable supply of usable energy is absolutely essential. |

The use of these vital raw materials has led to Europe being heavily dependent on high-grade imports of them, and this is set to increase in future, particularly as regards oil and, increasingly, natural gas.

| 1.5 | The expected lifetime of world-wide resources and reserves (3) of coal, oil and gas is dependent on several factors (economic growth, exploration and technological advances). It still extends over many decades (perhaps even centuries in the case of coal), although in the case of oil, in particular, there could be a drop in reserves and shortage of supply before the middle of the present century. The way the oil markets are going at the moment, there could be virtually unpredictable price hikes, even in the very short term, which could have a considerable impact on national economies (4). |

| 1.6 | The EU's energy policy must do everything to reduce this dependency over the long term, particularly by taking energy-saving measures, using all fuels more efficiently and making greater use of alternative energy systems, such as renewable and nuclear energies.

| 1.7 | On the other hand, the EU's energy policy must be fully geared to securing the supply and supply routes of fossil fuels, a particular problem here being the political stability of some of the main suppliers. Cooperation with the Russian Federation, the CIS states, countries in the Middle East and regions neighbouring the EU (such as Algeria and Libya) is particularly important in this regard. |

| 1.15 | In the transport field, every effort has to be made to cut the specific use of fuel (consumption per passenger-kilometre) and to prevent total consumption continuing to rise. This requires technological progress in many areas of vehicle and fuel development, measures to avoid traffic congestion (building of roads and tunnels/routing systems) and a reduction in traffic (6). Increased use of electric-powered vehicles, such as electric trains, reduces reliance on oil by allowing diversification in the use of primary energies (coal, gas, renewable energies, nuclear power). |

| 2.2 | The Committee has noted on several occasions that supplying and using energy puts a strain on the environment, involves risks and depends on unforeseeable and external political factors. None of the options and technologies which could contribute to future energy supply is technologically perfect, entirely free of adverse effects on the environment, suitable for all needs, and offers predictable pricing and availability over the long term. Added to this are the questions of diminishing reserves and resources with all that this entails. This difficult situation will be significantly exacerbated by the increase in the world's population, the increasing thirst for energy of the developing countries and, above all, the rapidly increasing energy needs of the big new industrial nations, such as China, India and Brazil. |

| 2.3 | A secure, long-term, environmentally sound and competitive energy supply must therefore remain a major goal of a forward-looking European energy policy. For the reasons given, this cannot rely on a few energy sources alone. Instead, the only way of countering energy shortages and other risks is through an energy mix that is diverse in type and origin and in which all available fuels and technologies are used and (further) developed so that eventually they can compete among themselves under accepted environmental conditions and in changing circumstances. |

| 3.2.1 | According to the reference prognoses (8) issued in 2004 by the International Energy Agency in Paris and the US Department of Energy's Information Administration (EIA), even 25 years from now, these fossil fuels will still account for over 80 % of the world's energy consumption. |

| 3.2.2 | The contribution of renewable energies will grow, but not at a rate above that of energy consumption, according to IEA and EIA estimates; their share will thus remain constant. If present trends continue, nuclear energy is also expected to take a slightly larger share in supply in absolute terms, but again, assuming the broad policy conditions do not radically change at EU level, the increase will be below the overall trend in consumption. As a result, the IEA and EIA are now even anticipating a decline in nuclear energy's share in covering the world's energy consumption. |

They are compared in terms of their energy content, measured in joules or watt seconds. |

| 3.6 | Only the recoverable part of resources is included in the Estimated Ultimate Recovery.

| 3.8 | It is reserves which are at the forefront of public debate, because it is from these that the coverage of energy sources is derived. By dividing reserves by current annual consumption, we get the ‘static lifetime’.

| 3.12 | Oil: More than a third of ‘conventional’ oil's EUR of 380 billion tons oil equivalent has been recovered so far. At present recovery volumes, half of the conventional potential would be used up in around ten years. Any increase in recovery after that would mean turning increasingly to non-conventional deposits (heavy oil, oil sand, oil shale). This would put back the Depletion Mid Point. Otherwise, there could be a drop in reserves and a drastic fall in supply (11) even before the middle of the present century. |

| 3.14 | However, exploration for gas (methane) hydrates and the technology for recovering them are still at the research stage, so no reliable claims can be made about how much they can contribute to the energy supply. On the one hand, there are estimates that the potential supplies exceed all the known supplies of fossil fuels, while on the other, nothing is certain concerning their recovery (basically technology and costs). Moreover, their release — whether due to climate change or the actions of man — is seen to involve an element of uncertainty, or even risk, as this could produce an accumulation of the powerful greenhouse gas methane in the atmosphere, which would be extremely damaging to the climate. |

| 3.15 | The costs of recovering fossil fuels differ greatly. Depending on the deposit, those for oil currently stand at between 2 and 20 USD a barrel. Although ever smaller deposits have to be developed in increasingly difficult geological and geographical conditions, these cost increases can be offset, or even more than offset, by gains in productivity, mostly based on technological innovation. In the case of natural gas, too, there are corresponding differences in recovery costs. In the case of coal, costs very much depend on the depth of the deposit, seam thickness and also whether it can be recovered by opencast or only deep mining. The cost range is considerable, from a few USD/t (e.g., in Powder River Basin in the USA) to 200 USD/t in the case of mining in certain European coalfields. |

| 3.16 | The regional distribution of fossil reserves, particularly those of oil, is also very uneven. 65 % of oil reserves are in the Middle East. The distribution of natural gas is only slightly better, with two key regions, the Middle East (34 %) and the successor states of the USSR (39 %). Coal reserves, on the other hand, are more evenly distributed. The largest coal reserves are in North America and there are also large coal supplies in China, India, Australia, South Africa and Europe. |

| 4.1 | Primary energy consumption in the EU of 25 in 2004 was around 2.5 billion tons of coal equivalent or around 75 exajoules (75 x 1018 joules). This corresponds to 16 % of the world's energy consumption of 15.3 billion tons of coal equivalent. At 5.5 tons of coal equivalent, the per capita consumption of energy in the EU of 25 is more than double the world average, albeit only half that in North America. In terms of the economic performance it produces, energy consumption in Europe is only around half the average in all non-European regions, as energy is used here substantially more efficiently than in many other parts of the world. |

At 5.5 tons of coal equivalent, the per capita consumption of energy in the EU of 25 is more than double the world average, albeit only half that in North America. In terms of the economic performance it produces, energy consumption in Europe is only around half the average in all non-European regions, as energy is used here substantially more efficiently than in many other parts of the world.

| 4.2 | The most important energy sources in the EU of 25 in 2004 — measured in total primary energy consumption — were mineral oil at 39 %, natural gas at 24 % and coal at 17 %. Other important staples of the EU energy supply are nuclear energy at 14 % and renewable and other energy sources at 6 %. The shares of the various fossil energy sources differ widely among the 25 Member States. They range in the case of natural gas from 1 % in Sweden to almost 50 % in the Netherlands, in the case of mineral oil from less than 30 % in Hungary to two-thirds in Portugal, and in the case of coal from 5 % in France to 60 % in Poland. The main reason for these differences is the different size of fossil energy reserves in the individual Member States. |

| 4.3 | The total energy reserves of the EU of 25 are comparatively tiny at around 38 billion tons of coal equivalent.

Coal supplies (lignite and hard coal), at 31 billion tons of coal equivalent, account for the bulk of this and are roughly equally divided between lignite and hard coal. Natural gas reserves stand at 4 billion tons of coal equivalent and oil reserves at 2 billion tons of coal equivalent. For the foreseeable future, the EU will remain the world's largest net energy importer. According to European Commission estimates, this dependency will increase to more than two-thirds by 2030. |

| 4.4 | The distribution of fossil energy reserves among the EU of 25 is very uneven. Oil supplies are concentrated particularly in the British and then the Danish North Sea.

Norwegian oil and gas reserves also play an important role because, although not a member of the EU, Norway is a member of the European Economic Area. |

| 5.2 | Primary energy consumption will rise by 2040 to 2.9 billion tons of coal equivalent — a mere 0.6 % p.a. However, GDP is expected to rise by 2.4 % p.a. up to 2030.

The share of fossil fuels in covering primary energy consumption will even increase by 2 percentage points, to 82 %, by 2030.

| 5.4 | Coal: After an initial downturn, coal consumption is expected to rise again around 2015 as the result of its improved competitiveness in electricity production. Rising gas prices and the anticipated availability of advanced coal-to-electricity conversion technologies are the main reasons for this development. On this assessment, coal consumption in 2030 will match that for 2000. Coal's share in primary energy consumption in the EU-25 will then be around 15 %, as it was in 2005. As a downturn of 40 % in coal extraction in the EU is expected in the period 2005 to 2030, together with an increase in coal imports of around 125 %, the share of imports in covering the EU-25's coal consumption will rise from 1/3 in 2005 to almost 2/3 in 2030. |

The Commission's estimate in its baseline scenario is that the expected increase in capacity will come from an increase of around 300 GW in fossil energies and around 130 GW in wind, hydro and solar energies, while nuclear plant capacity is expected to decrease by 30 GW between 2005 and 2030, failing any lasting change in overall policy. |

6.   Coal, oil and natural gas in a sustainable energy mix

| 6.1 | Coal, oil and natural gas are natural hydrocarbons produced over millions of years through a transformation from biological substances — deposited biomass; in effect, then, it is deposited solar energy. Different geological conditions in their formation (e.g., pressure, temperature and age) have resulted in different products. An important distinguishing feature is the fuel's hydrogen content. Natural gas has the highest ratio of hydrogen to carbon at 4: 1, while that of oil is 1.8: 1, and of coal 0.7: 1. This in large part determines the various applications to which these fossil fuels are put. |

However, their specific physical and chemical properties (state, hydrogen content, carbon content, ash content, etc.) make them particularly good for many applications and less so for others. Economic, technological and environmental criteria determine the choice of the hydrocarbon to be used. |

| 6.3 | Around 7 % of fossil fuels consumed in the EU are used for ‘non-energy’ consumption, i.e., mainly the production of chemical products. At the beginning of the last century reusable materials — initially ones derived from coal — were the basis for the newly emerging branch of manufacturing. Since then, hydrocarbon reusable materials have been almost completely edged out by natural gas and oil products. Oil and natural gas will continue to dominate in this segment of the market in future for as long as supplies remain. The lifetime of oil and gas reserves would be significantly longer if these fuels could be used less for producing energy and heat. |

Special precautions are needed in the case of offshore production. The methane produced in oil recovery should not be burned off, but put to industrial use. Something similar applies in the case of coal mining to the fire damp produced, which can contain large amounts of methane. |

| 7.3 | The European Large Combustion Plant Directive sets strict environmental standards for the building and running of power stations with a performance of ≥ 50 MWth.

Older plants are to be modernised. This should ensure that the emissions of dust (and fine dust, see 7.6), sulphur dioxide, nitrogen oxides and, above all, harmful heavy metals and toxic or carcinogenic organic substances are reduced to a tolerable level for nature and people. Noise levels must also be pre-emptively reduced to a level at which harm is avoided as much as possible. |

| 7.4 | Coal contains non-combustible substances which are separated (in electric or fabric filters) as ash following the combustion process in a power station.

| 7.6 | For a number of years now there has been intensified discussion of fine dust emissions (15). These are respirable suspended dust particles which are smaller than 10 μm and could be a trigger for respiratory diseases. Such particles are also emitted by oil and coal combustion, as the filters are not able to completely separate finer ash particles. The most important source of fine dust emissions, however, are vehicles running on diesel which are not fitted with particle filters. In coal and oil power stations dust emission is restricted by the European Large Combustion Plant Directive's ceiling of 20 mg/m. In large power stations fine dust emissions are further reduced by wet flue gas desulphurisation. To reduce fine dust emissions further and to maintain emission ceilings throughout Europe, stricter conditions for diesel vehicles have been enacted by the EU which make particle filters obligatory in cars from 2008. |

In coal and oil power stations dust emission is restricted by the European Large Combustion Plant Directive's ceiling of 20 mg/m. In large power stations fine dust emissions are further reduced by wet flue gas desulphurisation. To reduce fine dust emissions further and to maintain emission ceilings throughout Europe, stricter conditions for diesel vehicles have been enacted by the EU which make particle filters obligatory in cars from 2008.

| 7.7 | The desulphurisation of flue gases from large power stations and industrial combustion plants was made compulsory in some EU Member States as early as the 1980s. This put an end to the acidification of land and lakes that was already visible. The latest version of the European Large Combustion Plant Regulation prescribes an SO2 flue gas ceiling of 200 mg/m3 for plants >300 MW. The current state of technology allows separation of sulphur parts to a level of more than 90 %. New markets have been found for the products of sulphur separation, notably plaster, and the consumption of natural resources thereby reduced. |

At increased concentrations these nitrogen oxides can cause respiratory diseases and are also a precursor of environmentally damaging ozone.

Alongside increasing efficiency and energy-saving measures, CO2 separation technologies (see below) have the most potential for producing a considerable alleviation in the long term and therefore need to be developed. |

Moreover, gas is too important a raw material for the chemicals industry and the transport sector to be used for producing electricity. |

| 7.11 | Per energy unit, the combustion of natural gas produces only 50 % to 60 % of environmentally harmful CO2 compared with the burning of coal, because not only the carbon in the gas is used (burned), but also the hydrogen. However, methane itself — a main component of natural gas — is a greenhouse gas far more harmful to the climate (c. factor 30) than CO2. For this reason, everything must be done in the production and use of fossil fuels to prevent methane emissions. Methane released in the recovery of oil and coal must be captured and put to some use. It is also vital to avoid leakages of methane in transporting natural gas, as even the slightest losses in transit by pipeline are enough to offset the advantage natural gas has in this respect over coal. |

| 8.1 | In the EU of 25, coal, oil and gas power stations account for more than 60 % of the total installed capacity of power stations and thus form the backbone of electricity supply in Europe. The need to replace decommissioned power stations and to satisfy increasing demands made on power station capacity (see point 5.8) means that a considerable number of new power stations will have to be built within the next twenty-five years. Even with more intense use of renewable energy and an expansion of nuclear energy, coal and gas power stations will have to meet a substantial part of this shortfall. The greater the efficiency and pollutant capture rate of these power stations, the easier it will be to meet environmental and climate protection requirements. |

| 8.4 | Modern coal-fired power stations achieve an efficiency of more than 45 % using hard coal and more than 43 % using lignite. The steps needed to achieve an efficiency level of 50 % in coal power stations by 2020 are known.

Pre-treatment plants for drying lignite coal should be tested for a new generation of lignite power stations. Such ambitious development aims require the kind of international cooperation that exists in the EU projects AD 700 and Comtes 700 for the development of a 700° C power station. The demonstration of a new power station concept requires investments of up to EUR 1 bn. As individual companies are hardly in a position to bear the costs and risks alone, cooperation between European companies should be sought. |

Nevertheless, research and development should be advanced, including with public support, to locate and — if possible — tap its potential. |
