The developments in Galway, Ireland and Jutland, Denmark, will run on clean, renewable energy sources. They are expected to be operational in 2017.
Apple will also work with local partners in the development of new renewable energy projects from wind or other sources.
The company claims that the facilities will have the lowest environmental impact yet for an Apple data centre.
For the Irish project, Apple will recover land earlier used for growing and harvesting non-native trees and will restore native trees to Derrydonnell Forest.
In Denmark, the company will eliminate the need for additional generators by locating the data centre adjacent to an electrical substation.
The facility will grab excess heat and release it into the district heating system to help warm homes in the nearby community.
Apple CEO Tim Cook said: "This significant new investment represents Apple’s biggest project in Europe to date.
"We’re thrilled to be expanding our operations, creating hundreds of local jobs and introducing some of our most advanced green building designs yet."
Apple vice president of environmental initiatives Lisa Jackson said: "We’re excited to spur green industry growth in Ireland and Denmark and develop energy systems that take advantage of their strong wind resources.
"Our commitment to environmental responsibility is good for the planet, good for our business and good for the European economy."
