Part 7/9:
Reaching 50% clean energy by 2030 may be feasible, with projections suggesting that higher percentages are attainable. However, achieving towards 100% clean energy will face significant barriers due to technological limitations and the structural need for high-energy fuels in certain industries. While moving toward a 90% clean energy mix seems achievable, the last hurdle to reach full decarbonization will necessitate innovative solutions for energy sources that remain challenging to electrify.
