Why do different Green Tags offset different amounts of CO2?
This can be a complex topic, so let’s start with the basics and build from there. Green Tag purchases support new renewable energy projects, which provide clean energy to the national electric grid. Each Green Tag represents 1,000 kWh (or one MWh) of electricity from a clean, renewable resource. The more clean energy there is on the grid, the less need there is for energy generated by burning polluting fossil fuels (coal, oil, natural gas, etc).
