To limit the worst impacts of global warming and ensure energy security, countries all over the world develop energy roadmaps grounded in widely available, reliable and zero-emission technologies. [1] Wind power is one of several renewable energy sources that contribute to a balanced energy mix. It can be seamlessly integrated into the transmission system, ensuring no disruption while providing clean, renewable power.
This example from a Spanish system operator shows how various energy sources are layered to meet daily demand peaks, with wind (in light blue) contributing based on its availability. The mix of energy sources depends on policy and economic factors.
Electricity supply must constantly match demand, as it cannot yet be stored in large quantities. Wind energy is one of several sources used to meet this demand.
There are great benefits to coupling wind energy with other renewable energy sources. By combining wind power with other sources like solar and hydro, the grid can maintain a stable supply of electricity due to different operating profiles. Energy storage solutions, such as batteries, are expected to play a crucial role in balancing supply and demand, storing excess energy when wind conditions are favorable and releasing it when needed.
A set of studies in Denmark and Europe analyzed grid stability with renewable energy sources across electricity, heating and transportation sectors. These studies consistently found that renewable energy, combined with storage, district heating, and other efficiency measures, can meet demand without relying on nuclear power, natural gas or fossil fuels with carbon capture.

Wind energy is generated by converting wind into electricity using wind turbines. The electricity generated from wind power can vary at different times, such as hourly, daily or seasonally.
by the sun’s uneven heating of the atmosphere, the Earth’s irregular surface, and its rotation. Air moves because of temperature differences, with cold air being heavier than warm air.
enough kinetic energy every 24 hours to produce approximately 35 times more electricity than what human activities use daily. Unlike coal or oil, this resource is completely renewed each day.
Vestas takes millions of atmospheric observations daily worldwide. This helps us choose the best locations for our wind turbines.
