The Surprising Affordability of the Clean Energy Transition

The common perception that transitioning to renewable energy requires a massive surge in capital expenditure may be misleading, according to a recent analysis by RMI, a clean energy research group. Contrary to widely held beliefs, the buildout of renewable energy does not demand a significant increase in capital spending.

The study, named "The Great Reallocation," challenges estimates from organizations like McKinsey & Company and the International Energy Agency (IEA). RMI argues that many of these estimates fail to consider the decrease in fossil fuel spending, leading to inflated figures.

RMI found that energy supply capital expenditure is set to grow by 2 percent annually for the next seven years, aligning with the past seven years and significantly lower than the 2000s. Renewable capital spending is projected to double, while fossil fuel spending will likely halve by 2030. The main point is that financing the energy transition relies more on reallocating capital than a massive influx of funds.

Achieving this seems feasible as the required growth in energy supply capital spending is below expected global GDP growth. To illustrate, the additional capex needed for energy supply is just 1 percent of the $27 trillion global capex in 2022.

However, achieving this transition requires efforts to redirect capital from generation to grids and from developed markets to emerging markets. The primary obstacles identified are policy and expertise rather than a lack of capital availability.

RMI's analysis contradicts estimates from McKinsey, which projected an average annual cost of $9.2 trillion for the net-zero transition between 2021 and 2050. RMI argues that McKinsey's comparison is unfair, as it fails to consider the natural growth in the global economy and energy spending.

Similarly, the IEA's estimates are disputed by RMI, which contends that the IEA's inclusion of various capital cost categories leads to misleading figures. The clash revolves around how declines in fossil fuel spending are calculated and communicated.

In conclusion, the key takeaway from this report is that the transition to clean energy is not something with massive costs that we should fear. The transition to clean energy is the track we’re already on, but it’s unknown how quickly we’ll get there.
