With Scotland’s climate, you might think there is plenty of water to go around, however, Scotland can suffer from water shortages. Although rainwater can replenish rivers, lochs and reservoirs quickly, when there is a dry spell water levels can also drop rapidly.
In the UK, water use accounts for 6% of carbon emissions – this is same as the aviation industry. 1% of this comes from collecting, treating and pumping water to your home and treating the waste water before being returned to the environment. The remaining 5% is from the energy used to heat water in the home.
