2.8. Energy production
Due to both
population growth and economic growth, energy consumption and resulting
greenhouse gas emissions have been increasing in the pan European region,
despite energy efficiency improvements and an increased use of renewable energy
in certain areas. This trend is expected to continue if no additional policies
and measures are implemented. Total energy consumption throughout the
pan-European region is growing and remains dominated by fossil fuels. Despite
large reductions in some air emissions in parts of Europe, the energy supply
sector remains a major contributor to air pollution and greenhouse gas
emissions. Increasing investments in renewable energy production installations
in all regions remains a key tool to meeting environmental challenges and to
improving security of supply.
Increased use of
fuel for domestic use may increase the public health effects. Various forms of
electric power generation are associated with public and occupational health
impacts along the production life cycle - from fuel extract to waste disposal -
or recycling.
In general,
renewable energies seem to be preferable especially if no combustion is
involved in the different production stages. However, a holistic view is
necessary in order to analyze the public health impacts of energy production as
a basis for avoiding surprises and reducing risks in the future. The WHO has
summarized the health impacts of different forms of electrical power generation
below as shown in Table 2.4.

Many health
outcomes depend on the technology used, occupational health and safety
practices, measures of control of pollutant emissions, workers protection
legislation and practices and enforcement mechanisms. Many of these activities
are under the responsibility of the enterprise. The exposure of the local
population is very much dependent on the location of human settlements in
relation to pollution dispersal and population vulnerability. Such factors are
likely to significantly influence the associated health effects. We have to
make sure that the highest measures of protection are adopted by the
enterprises and energy companies, in order to control air, soil or water
pollutants’ impact on the environment and therewith on human health. Renewable
sources, such as photovoltaic and wind energy, are associated with fewer health
effects in general. There has been a shift in the types of fuels used, away
from coal and towards relatively cleaner ones, such as gas, in several central
and Eastern European countries, both in district heating systems and in
individual houses. The increased use of renewable energy, especially wind,
solar and photovoltaic energy, will have positive health benefits. The
production of electricity from nuclear sources has increased. Further major
increases in nuclear power are not expected, however, until after 2020, when
some increase may be necessary to meet the targets for reducing greenhouse
gases. As noted above, addressing public concerns about the human health
consequences of nuclear power accidents and nuclear waste disposal is a
"must" for policy makers. The market price of energy is also very
important for health; in fact, significant increases in prices of essential
forms of energy (e.g. as is currently the case for oil) are likely to have a
major impact on prices of manufactured and transported goods (e.g. food).
