Renewable Energy Sources

Ανανεώσιμες πηγές ενέργειας

The current energy challenges are:

  • ensuring energy resources with high adequacy to cover the continuously increased demand
  • reducing the environmental impacts from the production and use of energy, especially the impacts related to the climate change and air pollution

The RES and energy efficiency in buildings, infrastructure and transport play an important role in satisfying the energy demand in a sustainable way.

The use of fossil fuels in the production of electicity causes the emission of GreenHouse Gases (GHGs) which contribute in the phenomenon of climate change. The use of RES (wind, solar-thermal and photovoltaics, small hydroelectric stations, biomass and geothermal) contributes in the replacement of the conventional energy sources. Greece's national target for 2020 is the 20% replacement of the conventional energy sources with RES and the 20% reduction of the emission of the GHGs.

Greece's national target for energy efficiency for 2020 is 20%. Significant reduction in energy consumption (heating and electricity) results from renovation, better operation and maintenance and use of RES in buildings and infrustructures (e.g. thermal insulation, air conditioning, aeration and lighting). Considerable also reduction in energy consumption could result in transportation which currently consume fuel with 98% of its source from fossil fuels. This reduction could occur with alternative and renewable fuels in conjunction to sustainable transport strategies.
