When you collect a star, you can then click on one of your clouds to upgrade it: speed, capacity, generation rate. This also changes the look of the cloud, such as lightning for speed, rain for capacity, and sun for generation rate (which also helps you decide which of the existing clouds to conquer). I mostly used speed and generation. Don't forget to use space bar to select all clouds, which is also helpful for getting to a star more quickly.
