Renewable energy
In 2020, 89% of our electricity use was from renewable sources, significantly accelerating progress against our 2025 RE100 commitment. This was achieved through increasing renewable imported electricity to 99.9%1 and utilising 5.3GWh of on-site solar PV. The remaining 11% of power use was delivered by on-site combined heat and power (CHP) systems that use fossil gas. Decarbonising this source of electricity requires renewable fuels and these are under assessment as part of our emerging clean heat strategy.
As part of this strategy, we are investigating solutions for our global heat demand, delivered mostly through on-site combustion of fossil gas in boilers or CHP plants. In 2020, we joined the Renewable Thermal Collaborative, the leading coalition for organisations committed to decarbonising the energy required for heat in buildings and industrial processes.
In addition, we strengthened our commitments under the Climate Group's EP100 and EV100 initiatives: committing to double energy productivity and switch to 100% electric vehicles by 2025.
