Chapter 1: A Glimmer of Hope in Renewable Energy

In recent months, the news has been overwhelmingly grim, suggesting that the world is in a state of decline. Yet, amid this turmoil, a flicker of optimism emerges. We are on the verge of achieving one of the most critical objectives outlined in COP28. But can this truly make a meaningful impact in our fight against climate change?

Although COP28 had its fair share of criticism, with fossil fuel executives and lobbyists dominating discussions, the final agreement did introduce some significant commitments. One noteworthy pledge is the “Global Renewables and Energy Efficiency Pledge,” which aims to triple the global renewable energy capacity to 11,000 GW by 2030 and to double energy intensity improvements from 2% to 4% annually by the same year. These targets are aligned with the International Energy Agency's (IEA) recommendations to keep global warming below 1.5 degrees Celsius. If nations adhere to this promise, it could represent a substantial advancement in environmental preservation.

Achieving a threefold increase in renewable energy within just seven years is no small feat. This challenge is compounded by the need for more land, innovative technologies, and in some cases, entirely new infrastructure to support the efficient use of these energy sources. Nevertheless, recent data indicates that we are already making significant progress toward this ambitious target.

The IEA recently reported a remarkable 50% increase in global renewable capacity in 2023, totaling an impressive 510 GW. Notably, China alone added as much solar capacity in 2023 as the entire world did in 2022! The West hasn't lagged either, with the US and Brazil achieving record-high renewable installations.

According to IEA Executive Director Fatih Birol, current policies and market conditions put global renewable capacity on a path to increase by 2.5 times by 2030. However, he also cautioned that while we are making strides, we still need to accelerate our efforts to meet the COP28 target. Governments possess the necessary tools to bridge this gap and facilitate this growth.

The video titled "Fortnite - Save the World - Help with Your First Atlas Mission (Fight the Storm)" provides insight into teamwork and strategy that can be applied to collaborative efforts in renewable energy initiatives.

In other words, this monumental goal is achievable. A mere 20% increase in our current renewable expansion trajectory could bring us across the finish line. This can be accomplished through grants, subsidies, tax incentives, and other governmental support.

If we achieve this target, the implications would be profound, potentially cutting global energy emissions by 35% by 2030. Presently, the global energy sector is responsible for approximately 36.8 billion tons of carbon emissions annually, meaning we could be on track to reduce emissions by about 12.38 billion tons each year—a significant victory for our planet.

However, this outcome is contingent on our ability to double energy intensity improvements globally, which poses its own challenges.

To enhance the efficiency of our energy grids, we must invest in large-scale grid-level batteries that store excess energy for high-demand periods. This is particularly vital for renewables, which produce energy intermittently and unpredictably. The efficiency of the grid's architecture is also crucial; modern, high-voltage transmission lines are far more effective than older models, significantly reducing energy loss during transmission. Additionally, optimizing the layout of the grid can minimize the distance that renewable energy must travel to reach consumers, further enhancing efficiency.

Given that improving energy efficiency is a complex issue and the pledge's wording is somewhat ambiguous, assessing our progress in this area is challenging. However, a recent Bloomberg report estimates that global energy storage capacity could reach 1,877 GWh by 2030.

To put this in perspective, the United States consumes 16% of the world's energy supply. For renewables to comprise 94% of the US energy mix by 2050, an estimated 6,000 GWh of energy storage will be necessary. Currently, the world is adding enough storage each year to meet nearly a third of the US's 2050 requirements. In simpler terms, we are adding about 5% of the needed energy storage annually, suggesting we could meet our 2050 storage goals by 2044.

While we may not be entirely aligned with the energy efficiency targets outlined in COP28, we are at least on track to fulfill our global energy storage needs by the time we aim for net-zero emissions in 2050, heavily relying on renewable energy.

Thus, we are on a path toward preserving the planet. While the rollout of renewables needs to accelerate, this can be addressed. The expansion of grid-level energy storage must also be expedited, considering the finite lifespan of these installations. Fortunately, advancements in battery technology are making solutions more accessible and efficient. In summary, our journey toward net-zero emissions and saving the planet from ourselves appears increasingly plausible.
