Integration of Environmental Considerations at Different Levels of
Decision Making
Annex B: Energy Sector
B.1.1 Stakeholder Analysis
The Energy Sector in its narrowest sense may be defined as including:
public electricity and heat production and distribution; production of oil and gas;
petroleum refining; the manufacture of solid fuels-coke; and other energy industries which
include specific auto-production of electricity and heat. Of these public electricity and
heat production is by far the most important.
Energy production and consumption falls into two main types:
| electricity - generated from fossil fuels (gas, coal) and renewables. This is used as a
factor of production in all economic sectors, residential and transport users; |
| heat - mainly produced from natural gas or fuel oil and used for many purposes (e.g.
space heating, heating water, industrial processes) by domestic users, industry and
commercial. 85% of heat is produced in combination with power (combined heat and power -
CHP). |
At the macro level the key government actor is the Danish Energy Agency which sets the
policy framework and targets at the national level and provides fiscal incentives for
sustainable energy production and consumption.
At the meso level key actors include the Council for Sustainable Energy which is an
independent advisory body to the government and the Parliament, and a consultative body on
the national level with responsibility for promotion of energy conservation and efficiency
and the use of renewable energy, and launching new ideas and debate. Other meso level
actors are the Electricity Saving Trust (established in 1997) which aims to encourage the
substitution of electrical heating by district heating or heating with natural gas in
households and the public sector and the regulator of the newly de-regulated
energy companies. Municipalities and housing associations may also be considered meso
level actors in the energy sector since they are actively involved in setting procurement
policies for energy efficient products and for the fuel mix of energy supply to new
developments. They also have a role as energy consumers.
At the micro level the market based actors are the utilities and consumers.
The current ownership structure of the Danish electricity sector is complex with heat
and power generators being partly owned by municipalities and partly by the consumers. All
distribution companies have a so called public service obligation to supply,
to supply consumers that do not have the possibility to choose their own supplies. This
consists of a minimum package of services at a set price overseen by a public
regulator. On the other hand, distribution companies have the obligation to buy the
cheapest electricity. Deregulation of the sector as a result of the 1999 Electricity
Reform will see a concentration of productive capacity in the hands of two commercial
producers. The Danish electricity market is too small to contain additional producers.
Competition in the Danish electricity sector will come from abroad.
Consumers of energy comprise all economic actors including industry, transport and
other service providers and households. The latter includes both individual homeowners and
owners of apartments who may take decisions more collectively through housing
associations. The motivation of individual households also reflects the age of the
housing, type of housing (with very different incentives for individual houses and
apartments) and the age and income level of the residents (with pensioners singled out as
a group requiring particular financial support to make energy efficient choices).
Individual investors are also becoming an important target group in Denmark for raising
finance for developing renewables, particularly wind turbines.
B.1.2 Key Environmental Issues
The key drivers determining levels of energy use are:
| economic growth; |
| the growth in passenger and freight distances travelled, especially by road; |
| structural economic changes between sectors of different energy intensity in the economy
(ie energy consumed per unit of output); |
| fuel type and efficiency of use for power generation and heating; |
| social behaviour in relation to energy savings. |
The key environmental issues associated with energy production, transmission,
distribution and consumption are:
| climate change and acidification - mainly associated with fossil fuel use in electricity
generation, process heat and transport and their impacts on human health, materials, crop
and ecosystem productivity; |
| fugitive emissions including: emissions from oil transport, storage, refining,
transmission and distribution of oil products, venting and flaring; |
| waste generation from coal fired power generation; |
| land use and landscape issues principally associated with production and transmission of
conventional power and with renewable energy sources such as energy coppicing, biofuels
and wind turbines; and |
| water pollution and abstraction due to power generation. |
For the decision analysis described in Section B1.4 we have focused on two
inter-related sustainability decisions for this sector:
| Increasing production and supply of renewables by energy companies |
| Reducing household emissions of Green House Gases by reducing overall energy consumption |
|
B.1.3 Framework for Market Based decisions
Danish energy policy, as set out in Energy 21, aims to stabilise energy consumption and
increase the use of renewable energy sources and combined heat and power production. Key
drivers behind Danish energy policy are energy security, the EU electricity and natural
gas directives and environmental objectives. Goals outlined in Energy 21 are:
| to reduce CO2 emissions by 20 % compared to the 1988 level by 2005. |
| renewables should contribute to around 35 % of total primary energy supply in 2030 (235
PJ). (1) Currently renewables accounts for
about 9 % of the total energy demand, coming mainly from wind and biomass. The implied
target is a 1 % per year increase to 2030. Energy 21 stresses renewable energy as a
priority research area. The Danish programme for the Development of Renewable Energy
(DPRE), established in 1991, aims to provide support for the development and
implementation of renewable energy technologies. In 1996 grant payments under the
programme amounted to DKK 65 million. (2)DPRE
is supplementary to the Danish Energy Research Programme (ERP). The framework for
renewables is also set by the Electricity Reform Agreement, 1999 which provides for
substantial modification of the support for renewable energy from subsidies to a market
based scheme. |
| a greater use of biomass and 2-300,000 ha of energy crops (3) are expected to contribute 145 PJ annually by 2030.(4) This is expected to lower Denmarks total CO2
emissions by around 12.5 %. The Biomass Agreement outlines the future use of
biomass. Electricity utilities are obliged to use 1.2 Mt of straw, 200,000 tonnes of wood
chips and 200,000 tonnes of either straw, wood chips or willow chips annually by
2000. (5) This represents 6 % of the total
consumption of coal. |
| CHP is a key element of the CO2 emissions reduction strategy. By 1998, 50 %
of the electricity generated for domestic supply was produced as CHP. The bulk of the
countrys future heat demand and electricity consumption is expected to be covered by
CHP, including district heating plants running on biomass. |
Other policy tools which currently set the framework for decision making in relation to
reducing demand for conventional energy sources and increasing supply of renewables are
summarised in Table B1.1 and Table B1.2 respectively.
Table B1.1 Tools which provide the macro framework for demand
reduction decisions in the energy sector in Denmark
Tool |
Aims and description |
Regulation |
| Inspection of oil burners used in central heating systems by authorised firms since
1997; the initiative is supported by an information campaign with the objective of
increasing energy efficiency in new buildings by 50% by 2005. |
| Since 1992 energy management and annual reporting on energy consumption have been
mandatory in every government building. |
| Local energy managers must be appointed by every institution. |
| Mandatory individual metering of all buildings since 1997. |
|
Energy Labelling Schemes |
| Energy labelling for domestic appliances (fridges, freezers, washing machines,
dishwashers, office equipment, lighting, electric motors, process ventilation, pumps,
boilers and technical insulation) in line with EU programme. |
| Energy arrows inform consumers of electricity consumption of different appliances
(developed by utilities). |
| Voluntary scheme for other products gives a label to the best products on the market,
updated on an annual basis |
|
Energy labelling of buildings |
| Since 1997 mandatory audits and labelling of small buildings (1,500 m2) by the vendor
prior to sale. |
|
Guidance |
| Building Code 1995 sets limits for heating and ventilation systems. |
| Future changes aimed at ambitious energy efficiency targets (45 kWh per m2) are expected
to enter into force by 2005 |
|
Subsidies |
| Grants for energy saving investments in central government buildings financed from a tax
of 5% on government energy consumption. The annual yield of this tax is around DKK 50
million. |
| subsidies for energy savings in pensioners dwellings |
| compulsory energy conservation pool financed by contributions based on consumption at
county and municipal level being considered. |
| Subsidies for installation of water borne central heating in housing erected before
1950. Some 65000 dwellings to be connected over 10 years. |
| Electricity Conservation scheme: investment grants for heat saving or support for
development of supplementary sources of energy, with a particular focus on switching
electric heating in areas with district heating and natural gas supply. Financed for fixed
amount levy on household and public sector energy consumption. Annual total of DKK 100
million. |
|
Reporting |
| Introduction of green accounts at county and municipal level is being considered. |
| More detailed, frequent and graphic reporting of individual household consumption on
electricity bills. |
|
CO2 quota system |
| Power companies will be allocated a specific emissions cap within the framework of a
total cap of 23 million tonnes of CO2 for 2000, falling to 20 million tons in
2003. Over the following three years the total will drop by 1 million tons annually. For
each ton of CO2 by which a company exceeds its quota it will penalised $5.60.
Unused amounts may be banked and applied to the following year. The quotas will be
tradable within Denmark only but the government hopes that over the next few years the
system can be expanded at least to the Baltic region. The measure aims to support combined
heat and power (co-generation) which is widespread in Denmark by taking account of the
amount of heat produced when calculating a plants CO2 emissions. |
|
Energy efficiency subsidies |
| Subsidies are granted for the development and implementation of energy efficiency
appliances and products with a focus on dwellings and the public sector. Subsidies will
also be granted for marketing and procurement of energy efficiency products. |
|
Negotiated Agreements |
| Voluntary agreements on energy efficiency will be negotiated with trade organisations,
housing associations etc for specific products and technologies. |
|
Purchasing policies |
| Buying clubs are drawing up stringent requirements related to energy
efficiency, price, materials for products and then guaranteeing contracts to the best
performing manufactures. |
| From 1997 housing associations have been encouraged to take this route on energy
efficiency. |
|
Table B1.2 Tools which provide the macro framework for promotion of
renewables in the energy sector in Denmark
Tool |
Aims and operation |
Regulation |
| The Heat Supply Act requires municipalities to draw up heating plans including district
heating. Renewable local energy sources (straw, biogas, forestry residues, waste
incineration etc) have to be considered. |
|
Green electricity certificates |
| An important new development in the electricity reform of 1999 is the development of a
market in green certificates, which represent the production of green energy. Utilities
have an obligation to purchase green certificates. The most efficient (competitive)
renewable energies are encouraged to develop through the price system. If the
consumer/distribution companies of electricity do not fulfil their quota, a penalty of
0.27 DKK/kWh is levied. |
|
Green taxes |
| Taxes and tax concessions on different sources of energy aim to restore the price
imbalance between fossil fuels and non-fossil fuel energy. |
|
Subsidies |
| Subsidies are paid to generators of electricity from renewables which act as
compensation for the automatic levying of the CO2 tax on all electricity. For a
period still to be specified, the following fixed tariffs apply to power generated from
biomass: |
| Biogas plants: 0.33 DKK/kWh |
| Local biomass plants: 0.27-0.33 DKK/kWh |
| For biogas and biomass plants erected during 2000,2001 and 2002, a fixed tariff of 0.5
DKK/kWh will apply for 10 years. |
| In addition an electricity production subsidy of 0.17 DKK/kWh is available. In 1996
support in subsidies amounted to DKK 276 million for wind power and DKK 122 million for
biomass. |
|
Obligation to purchase green energy |
| The current system of state subsidies for wind power is to be replaced by an obligation
on consumers and energy distributors to obtain up to 20% of the energy they use from
renewable sources. The only exception will be large users who will face this obligation
for only up to 100 GW of electricity. The Danish Energy Agency does not expect it to be
fully functional until 2003. |
|
Buy-back rates for wind generated electricity |
| Fixed prices have been set in the electricity reform in 1999, for wind energy sold to
the grid |
|
Reporting and awareness raising |
| Council for Sustainable Energy responsible for major awareness raising campaigns and
events |
|
Subsidies for households |
| Subsidies are offered to replace an oil boiler with a biomass boiler. The subsidy for
the biomass boiler varies from 10 to 30% of the investment. In 1996 the Danish Energy
board granted a total of 128 million DKK. |
|
Danish Programme for Development of Renewable Energy |
| Established in 1991, it aims to provide support for the development and implementation
of renewable energy technologies to fulfil national energy plans. In 1996 grant payments
under the programme amounted to DKK 65 million. Support is given to development of
technologies, dissemination of information and investment subsidies are granted for the
purchase of straw and wood pellet boilers, small scale biogas plants, solar panels, heat
pumps etc. DPRE is supplementary to the Danish Energy Research Programme. |
|
Development and Demonstration Programme for Renewable Energy |
| Investment subsidies are offered to spur the dissemination of commercially available
technologies. The subsidy varies between 15-30% of the construction costs. In 1996 a total
of 71 million DKK was spent on investment subsidies. Subsidies for demonstration of
pre-commercial technologies amounted to 56 million DKK. |
|
Renewable Energy Island |
| The island of Samsoe with 4,400 inhabitants will have its entire energy supply based on
renewable energy, including the transport sector. The programme will be financed from the
existing grant schemes. |
|
B.1.4 Decision Flow Analysis
Decision flow analyses were completed for the energy sector for individual households
and energy generators in relation to climate change and demand management, specifically
reducing energy demand and greenhouse gas emissions. The results are presented in Tables
1.3 and 1.4 and discussed below.
A key question for households is what type of property to buy, whether to buy or rent a
house or apartment, old or new, energy efficient or not. The key parameters in making this
decision are:
| The availability of old and new energy efficient houses and apartments on the
market. This will reflect building regulations and guidelines for new housing, the energy
efficiency policies of builders, architects and housing associations. The average life
span of the housing stock and the frequency with which housing is renovated and
refurbished and how building codes apply to older buildings. |
| Awareness of energy issues by house buyers, renters, vendors and landlords. This
will depend on the extent that everyone involved in the housing chain understands energy
conservation, its relation to climate change and to the costs of building, refurbishing
and heating a dwelling. The extent to which individual apartments in blocks are separately
metered and billed according to energy usage is also important. |
| Affordability. When comparing the potentially high costs of undertaking energy
conservation measures, households will take into consideration the capital costs of the
works, the tenure (whether they own or rent the property) and how long they expect to be
there. They will then consider the likely pay back time and the expected impact on the
sale price and ease of sale. The cost of capital works can be influenced by the
availability of grants and tax breaks for carrying out the works and offering EcoMortgages
and other financial incentives for the purchase of energy efficient housing. |
Another key decision for households is what type of fuel or electricity to use. This is
affected by the following parameters:
| Availability of green fuels or district heating. This will be affected by
infrastructure for producing and distributing renewable electricity and district heating
and ease of connection in a given area. This is likely to be a major framework condition
for the success of integrating environmental considerations into energy choices. |
| Awareness of energy choices, which will be affected both by wider awareness
raising of energy issues and the extent to which municipal and commercial energy providers
make their customers aware of the options. |
| Cost. If green electricity is available its price will depend on the source of
energy (with only energy from waste and biomass being comparable in price to conventional
sources), the pricing policies of the energy providers and any government subsidies for
the production of renewables energy or price support to consumers . In the US and UK a
small niche market is developing of consumers who are prepared to pay a 5-10 % premium
over the normal tariff for the purchase of renewables. |
| Reliability of supply. Renewable sources are less likely to suffer from negative
perceptions of poor quality or reliability than some other environmentally preferred goods
or services (such as public transport or low energy appliances). |
| Habit. An important parameter affecting environmentally sound purchasing
decisions where consumers have the necessary knowledge, access to products or services and
the correct pricing incentives may be inertia and a lack of willingness to change
established behaviour. This is less likely to be a factor for renewables or district
heating than for other green consumables where for many the market and
acceptability of products has yet to be firmly established. |
Having made the decisions about the energy efficiency of housing and the type of energy
supply householders are also faced with the decision of what type of household appliances
to buy. Their choices will reflect the following parameters:
| Availability. The availability of low energy appliances on the market. This will
be affected by legislative requirements on producers, wholesalers and retailers of
appliances. |
| Cost. This will be affected by the market conditions on the supply side, the
additional costs of producing energy efficient products and whether any higher costs are
passed on to the consumer. Consumer choice will reflect the actual price differential, how
long the appliance is expected to last and the expected pay back time. |
| Perceived quality. This will depend on consumers awareness of energy saving
as an issue, and the extent of knowledge about the attributes of the appliance relative to
conventional ones. This parameter can be impacted by awareness raising campaigns, eco
labelling or energy consumption labelling of products and provision of point of sale
advice and advice helplines. |
Decisions about how much energy to use reflect the type of property and appliances and
lifestyle decisions about how much heating, lighting and space heating is required. These
choices are affected by all of the same parameters as above and in particular price,
awareness and information about energy use and opportunities for sharing of some
facilities (eg washing machines and dryers in apartment blocks).
The key framework conditions affecting how households integrate environment into their
day to day decisions are probably the availability of green power and products, the price
differential between these and conventional products and their general awareness. The
major instruments which have been used to affect these decisions to date include economic
instruments (mainly subsidies for the domestic sector), ecolabelling of household
appliances (fridges, freezers, washing machines etc) and energy efficiency advice to
homeowners supported by a legal requirement to undertake an energy audit and subsidies to
undertake the necessary works to make houses energy efficient .
