Bill McKibben Delivers an Inspiring Case for Solar Energy in His Latest Book

The Sun Comes Here
(Bill McKibben) WW Norton UK, September 16th. US, August 19th

The sun is shining brighter through solar energy. According to Ember, a think tank on energy, solar energy has been the fastest-growing power source globally for the past two decades.

In 2022, solar power generation capacity surpassed 1 terawatt for the first time, and just two years later, it doubled, contributing 7% to the world’s electricity supply. When including wind turbines, which harness solar energy through different methods, solar accounted for 15% of global electricity last year.

This surge in solar energy is not simply due to an increased commitment to climate goals. Indeed, as noted in another Ember Report, many renewable energy targets have barely made progress towards achieving net-zero emissions over the past decade.

The true driver behind the rise of solar is its position as the most cost-effective method of electricity generation almost everywhere.

In his book Here Comes the Sun: The Last Chance for Climate and a New Chance for Civilization, long-time climate advocate Bill McKibben asserts that we are on the brink of a critical historical transition—from reliance on fossil fuels to embracing solar energy. “We are looking to the heavens for energy instead of to hell,” McKibben writes.

Below, he provides a thoughtful exploration of how solar energy not only addresses climate issues in time but also transforms the interaction between the economy and the natural world.

This is not the first call to action for a swift transition to renewable sources. However, it offers a visionary glimpse of what a solar-powered society could look like, going beyond just technological and economic considerations during the energy shift.

“This critical transformation is now presented as the most significant bargain ever, yet it remains cloaked in mysteries we have yet to fully unravel,” he notes.

This optimism is presented by McKibben, a renowned voice in environmentalism since his first book, The End of Nature, where he first alerted the world to the climate crisis.

Rather than detailing the ongoing damage from climate change, he emphasizes the numerous advantages of increased solar power, including more stable energy prices and reduced reliance on fossil fuel-rich states.

On a spiritual note, he suggests that this shift may rekindle our deep respect for the sun and its immense power.

McKibben also engages with skeptics of renewable energy, providing a balanced perspective on the trade-offs in the energy transition, such as the rising demand for minerals, land use, and potential job losses in fossil fuel industries. His argument is reinforced by an array of global anecdotes from different energy transitions, including a positive mention of the Kentucky Coal Mines Museum’s transition to solar energy to cut costs.

Nevertheless, doubts linger about the feasibility of McKibben’s optimistic outlook. A significant portion of the rapid growth in solar energy is currently occurring in China, which has unique advantages such as central planning and a distinct political structure that may not be replicable elsewhere. This rapid pace may not even be sustainable in China itself.

In the U.S., despite remarkable growth in solar energy in recent years, the industry now contends with challenges posed by the previous administration’s discontent towards renewable resources. Loss of tax credits that once leveled the playing field with subsidized fossil fuels and local opposition to solar projects also complicate future growth.

As McKibben acknowledges, both can be true: solar-driven energy transitions may be on the horizon, but reductions in emissions might not happen swiftly enough to avert further drastic impacts of global warming. “It won’t be easy, but it’s necessary,” he asserts. “We must cease burning, or we will face dire consequences.”

Personally, I resonate with this perspective—I’d much prefer to bask in the sunlight.
