This depends on the fuel mix of the energy supplier you are using (ie. what percentage comes from fossil fuels and what percentage comes from renewable energy).
Maeving encourages all customers to choose and support electricity suppliers that draw from 100% renewable energy. A list of energy suppliers and their respective fuel mixes can be found here.
