Renewable electricity consumption (CSI 031/ENER 030) - Assessment published Aug 2011

Indicator definition

The share of renewable electricity is the ratio between the electricity produced from renewable energy sources and gross national electricity consumption, expressed as a percentage. It measures the contribution of electricity produced from renewable energy sources to the national gross electricity consumption.

Renewable energy sources are defined as renewable non-fossil energy sources: wind, solar, geothermal, wave, tidal, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases. Electricity produced from renewable energy sources comprises the electricity generation from hydro plants (excluding that produced as a result of pumping storage systems), wind, solar, geothermal and electricity from biomass/wastes. Electricity from biomass/wastes comprises electricity generated from wood/wood wastes and the burning other of solid wastes of a renewable nature (straw, black liquor), municipal solid waste incineration, biogas (incl. landfill, sewage, farm gas) and liquid biofuels. Gross national electricity consumption comprises total gross national electricity generation from all fuels (including autoproduction), plus electricity imports, minus exports.

Projections are for 2020-2030 from the POLES (IPTS) Baseline and GHG Reduction Scenario, from the WEO 2009 (IEA) Reference and Alternative Policy Scenario (450) and PRIMES (EC) baseline and reference scenarios.

Units

Electricity generation is measured in either GWh or TWh (1000 GWh). The share of elecrticity generated from renewable energy sources is express as percentage.

Policy context and targets

Context description

Environmental context

The share of electricity consumption from renewable energy sources provides a broad indication of progress towards reducing the environmental impact of electricity consumption on the environment. Increasing the share of renewables in electricity consumption will help the EU to reduce the GHG emissions from power generation but the overall impact will depend on which generation sources are being replaced in the energy system.

Emissions of air pollutants are also generally lower for renewable electricity production than for electricity produced from fossil fuels. The exception to this is the incineration of Municipal and Solid Waste (MSW), which due to high costs of separation, usually involves the combustion of some mixed wastes including materials contaminated with heavy metals. MSW incineration also causes emission of particulate matter which, depending to what degree the waste is burned and at what temperature, can be higher than those from fossil fuel combustion. Lower temperatures cause larger particles to be emitted, which can be linked to respiratory diseases. Emissions to the atmosphere from MSW incineration are subject to stringent regulations including tight controls on emissions of cadmium, mercury, and other such substances.

The implementation of renewable energy sources may have negative impacts on landscapes, habitats and ecosystems, although many impacts can be minimised through careful site selection. Hydropower schemes in particular can have adverse impacts including flooding, disruption of ecosystems and hydrology, and socio-economic impacts if resettlement is required (for large hydro). Some solar photovoltaic schemes require relatively large quantities of heavy metals in their construction and geothermal energy can release pollutant gases carried by hot fluids if not properly controlled. Wind turbines can have visual impacts on the areas in which they are sited. Some types of biomass and biofuel crops have considerable land, water and agricultural input requirements such as fertilisers and pesticides.

That said,renewable energy is by nature more sustainable than the combustion of fossil fuels, and in many cases more efficient. It will undoubtedly play a big part in curbing the atmospheric concentration of CO₂ at 450ppm, which is commonly understood to be the safe limit. By continuing to burn fossil fuels, we would continue to raise atmospheric CO₂ which poses unknown risks to ecosystems, possibly far greater than those from renewable energy implementation.

Sets an indicative target of 21% of renewable electricity in gross electricity consumption in 2010 at EU level. Fulfilling this target will also help meeting the new, mandatory target of 20% renewables in final energy consumption in 2020 set by the Directive 2009/28/EC (see also ENER 28).

Targets

According to the renewable electricity directive (2001/77/EC), the overall EU-27 target is a share of 21.0 % of renewable electricity in gross electricity consumption by 2010. In 2009, the share was 19.8 %. If the trend of the last 20 years is pursued, continued, the EU will reach 20% energy generation from renewable sources. Given that the trend in recent years is actually increasing, there is reason to be confident in meeting the 21% objective by 2010. Within the EU-27, only Hungary, Lithuania and Luxembourg have already reached their indicative target and three countries, Bulgaria, Germany and Estonia are very close to reach their objectives (see Figure 2). It follows that at an individual country level, there is still much ground to be made up.

Uncertainties

The renewables electricity directive (2001/77/EC) defines the share of renewable electricity as the percentage of electricity produced from renewable energy sources in gross electricity consumption. The numerator includes all electricity generated from renewable sources, most of which is for domestic use. The denominator contains all electricity consumed in a country, thus including imports and excluding exports of electricity. Therefore, the share of renewable electricity can be higher than 100 % in a country if all electricity is produced from renewable sources and some of the over-generated renewable electricity is exported to a neighbouring country.

Biomass and wastes, as defined by Eurostat, cover organic, non-fossil material of biological origin, which may be used for heat production or electricity generation. They comprise wood and wood waste, biogas, municipal solid waste (MSW) and biofuels. MSW comprises biodegradable and non-biodegradable wastes produced by different sectors. Non-biodegradable municipal and solid wastes are not considered to be renewable, but current data availability does not allow the non-biodegradable content of wastes to be identified separately, except for industry.

The electricity produced as a result from hydropower storage systems is not classified as a renewable source of energy in terms of electricity production, but is part of the gross electricity consumption in a country.

The share of renewable electricity could increase even if the actual electricity produced from renewable sources falls. Similarly, the share could fall despite an increase in electricity generation from renewable sources. Therefore, from an environmental point of view, attaining the 2010 target for the share of renewable electricity does not necessarily imply that carbon dioxide emissions from electricity generation will fall.

Electricity consumption within the national territory includes imports of electricity from neighbouring countries. It also excludes the electricity produced nationally but exported abroad. In some countries the contribution of electricity trade to total electricity consumption and the changes observed from year to year need to be looked at carefully when analysing trends in renewable electricity. Impacts on the (national) environment are also affected since emissions are accounted where the electricity is produced whereas consumption is accounted where the electricity is consumed.
