Although it is almost impossible to create a sustainable energy system without cost increases, it is important to keep these as low as possible. Every economic activity is dependent on energy in one way or another, so an excessively costly system would likely lead to increased poverty. The target for the increase of energy costs is set at 10% and for electricity at 50%.The increase for electricity is higher, since a lot of processes, like space heating, that are fuel based in 2012 will likely be electricity based in 2030. Also, household electricity prices in the Netherlands are a lot higher than electricity prices for companies in 2012. Increasing the price for firms to the level of households would mean a rise of more than 50%. Because of this, 50% price increase seemed reasonable.
