Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Science has an important part to play in our everyday existence, and there is far too much neglect of science; but its intention is to supplement not to supplant the familiar outlook.
Arthur Eddington, Science and the Unseen World (1929).
Power generation from a renewable resource like wind directly depends on the weather, which cannot be easily predicted. An EU initiative improved wind power and electricity demand forecasting in order to make wind power more valuable on the power market.
