European sustainable energy week encourages individuals, businesses and government to come up with ways of saving energy.
Currently around 10% of the energy used in the EU comes from renewable sources like solar power, wind turbines, hydroelectric plants and biomass. Every year since 2005, European sustainable energy week has been promoting the development of renewable energy - with the message that we can all do our bit to reduce the amount of energy we consume.
From 11 to 15 April, some 600 events will be taking place, involving around 30 000 people from 43 European countries. This year the focus is on energy efficiency and renewable energy.
For example, in the Swedish town of Örebro, the winners of a county-wide quiz will receive low-energy products as prizes.
In Albacete (Spain), a local agency will teach people how they can use up to 15% less fuel by adjusting their driving style.
The role of businesses and business leaders in creating a more eco-friendly economy will the discussed at an informal get-together in Paris.
In Brussels, conferences and exhibitions will bring together politicians, industrialists and scientists for the biggest ever European forum on sustainable energy. Topics for discussion will include making buildings more energy efficient and the greening of European industry.
And European sustainable energy awards will be presented to the most ambitious and innovative projects from around Europe. Last year, one of the awards went to a project in Budapest that helped schools to cut their energy consumption by as much as 40%.
All of this will help the EU to hit the targets it set itself for 2020: a 20% reduction in greenhouse-gas emissions, 20% of energy needs to be met from renewable sources, and a 20% cut in energy consumption.
