I don't have the precise figures with me, but in terms of the use of primary energy in Europe, it is in the order of magnitude of 6% or 7%, depending on which sector. It is more in electricity. It is less, for example, in other sectors, such as biomass. But the objective is to go with a binding target, by 2020, up to 20%. So it is three times what we have in place today.
The real question that is hotly debated now is to what extent we are going to have incentives in place that are in line with the liberalization of the electricity market that we are currently undergoing in the European Union, because most of the incentive schemes for renewables are very much tied to the different member states. For sure you will know that in Denmark, for example, wind energy has been booming, as it is also in the north of Germany, but the support systems of Denmark and Germany have been particularly generous to the development of the wind energy there.
When we are moving from something covering 6% or 7%, up to 20%, it becomes a major vector in the energy production and in the liberalization of the electricity and energy markets we have today in Europe. So we will see in the coming year or two quite a bit of intensive debate on what kind of specific support systems for renewable energy we are going to have, on top of the carbon market that we have today, because we know that the carbon market—today around 15 euros per tonne of carbon dioxide, up to prices for the 2008 to 2012 period—is a very important stimulus or incentive for the development of renewable energy. The question is, what should we do on top of that? It's clearly not enough.
Some are expecting a price that is higher than the 15 euros we have today. To the extent that the prices are going to be higher, less other support and specific support systems are going to be needed. But that is one of the issues where the commission is going to take more initiatives after the explicit support that we hope we will get from the heads of states and government on March 8 and 9.
