A Reminder…The sources of greenhouse gases can be grouped into five categories:
- Transportation is the biggest, perhaps electric vehicles will reduce this number, over time. Hydrogen is still on the list.
- Electricity generation is second. The chart below shows the contribution of renewable sources to the generation of electricity.
- Industrial greenhouse gas emissions primarily come from burning fossil fuels for energy, as well as greenhouse gas emissions from certain chemical reactions necessary to produce goods from raw materials.
