Against the background of the climate protection objectives of the Kyoto Protocol, the development
of renewable energy sources since 1990 is of special interest. To date, however, it
has not proved possible to achieve any marked increase in their share of energy supplies. On
a global scale, energy supply from renewables grew by an average of 1.9 % per annum until
2008, which was on the same level as the growth in total primary energy consumption.
Since 2005 a change in the trend has been observed in the industrialised countries (OECD),
with growth in renewable energy supplies, at 1.5 %, for the first time exceeding the growth
in total primary energy consumption (2005: 1.4 % p. a.). In 2008, renewable energies
achieved growth of 2 % p.a., while the pace of growth of total primary energy consumption
in the OECD continued to fall from 1.2 % p.a. in 2007 to 1.1 % p.a. in 2008.
