Tonik fuel mix

All of our tariffs include 100% renewable electricity, but we’re often asked about how it is generated. This year we’re pleased to report that from 1st April 2017 – 31st March 2018, our electricity came from two sources: 68% was generated from wind and 32% from solar.

Our energy is backed and guaranteed through Renewable Energy Guarantee of Origin (REGO) certificates with Ofgem. So for every unit of electricity that our members use, we buy REGOs to ensure that a unit of electricity from 100% renewable sources, has been generated and fed back into the grid to replace it.

This is in stark contrast to the national average, where only 29.04% of electricity is renewably generated. The remaining 70.96% of non-renewably generated electricity results in an environmental impact of 225g of CO2 emissions and 0.007g of high level radioactive waste per kWh produced. But because renewable electricity avoids fossil fuels and nuclear power, it is carbon neutral and produces no radioactive waste whatsoever.

The average UK household uses 3100kWh a year, which equates to 697kg of carbon dioxide and 21.7g of radioactive waste.

To put that in perspective, a 697kg reduction in carbon dioxide emissions is equivalent to driving 7,567km in an Audi A1*. To put that into further perspective, you could drive from Birmingham to Beirut and back again!
