Introduction
 In recent years, the consumption of fossil fuel and the
mitigation of climate changes have become major
challenges for governments all over the world. To engage
these challenges, many countries are pursuing the
research, development, and demonstration of renewable
energy sources
 During the last few years, political support for renewable
energies has been growing continuously both at the national
and international level.
 The increased use of renewable energy sources in the heat
market can significantly alleviate the negative effects of
high-energy costs on the national economy.

diversification of fuel,
municipal waste utilization possibilities for heat
and electricity generation,
integration of industrial excess heat to district
heating networks.

Situation after 2006
 Looking at the renewable energy use after
2006, it was a natural gas price boom,
increase of social and political pressure for
fast developments in clean energy, and
financial crisis, which requires adequate
government measures to stimulate the
economy.

Impact of legal regulation (1)
 Legal regulation became an important tool to
diversify energy supply, to reduce air pollution and
to meet targets of sustainable development.
 Sustainable development model guarantees to the
present generation the ability to meet our needs
without detriment the ability of future generations.
 The main factor limiting further renewable energy
growth in district heating is high investment costs
and constraints of legal regulation.
Impact of legal regulation (2)
 Despite the government policy efforts,
accepted legislated base and programs for
enhancement of the use of renewable energy
sources, due to expensiveness of alternative
energy technologies and various constraints,
total contribution to development is not
impressive.
 More effectiveness can be obtained on
cooperation with other countries.
District heating in Lithuania
 Lithuanian district heating system has been
developed during planned economy times,
and problems of district heating sector are a
heritage of planned economy.
 This is one of the most threatening economic
and social problems at the moment.
 Social policy decisions with unstable energy
policy distort market signals to the
consumers.
Importance of renewable energy
 The European Union's policy stimulates
changes in heating sector.
 The Renewable Energy Sources Directive
2009/28/EC translates binding targets into a
legislative framework.
 Renewable energy development in district
heating that is encouraged by laws requires
large investments.
