Reminder…Sources and Uses of Energy

 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.
