In order to limit global temperature rise, we need to increase our use of non-fossil based energy sources. These include solar and wind energy and other renewable sources of energy, such as those based on biomass. The adoption of renewable energy sources has implications for spatial planning, as solar and wind parks can take up large areas of the earth's surface. How to go about planning and implementing the energy transition is the subject of much public debate: Where should solar and wind parks be located? What are the effects of these energy parks on biodiversity? Wageningen Environmental Research combines its scientific knowledge on renewable energy with its expertise on spatial planning to offer stakeholders support in implementing energy transition measures.
