The transition to clean energy requires a fundamental shift in mindset, from a linear perspective to an exponential one. Energy incumbents often perceive change as linear, while the new energy reality is exponential, demanding agility and adaptability. The US currently dominates the old energy industries but is not the technological epicenter of clean energy, with China leading the way in renewable energy and supply chain development.

The Importance of Proper Modeling:
Official renewable energy forecasts may underestimate the potential of renewables due to inadequate modeling practices. Many models do not adequately capture the impact of efficiency and renewable learning curves, leading to an underestimation of renewable contributions. Proper modeling using actual market prices and observed learning curves shows that a rapid transition to clean energy is feasible and cost-effective, without the need for costly and risky technologies like CCS or BECCS.

The Economic Benefits of a Clean Energy Transition:
Contrary to popular belief, a clean energy transition can be more cost-effective than continuing with business as usual. The fast transition scenario, which aims to phase out fossil fuels by 2040, is significantly cheaper than a slow transition or no transition at all. The faster the transition, the lower the total cost, as renewables become cheaper even sooner. Stranded assets can be largely avoided through careful planning and investment in depreciation and service demand growth.

The Shift from Carbon to Silicon:
The ongoing energy transformation marks a shift from the age of carbon to the modern age of silicon.
