Despite political challenges, the U.S. renewable energy sector is experiencing rapid growth. Solar and wind technologies are now cheaper and faster to deploy than fossil fuels, with significant public support and investment driving this transition. Events like Sun Day on September 21st aim to mobilize citizens for clean energy advocacy, marking a pivotal moment in the shift towards a sustainable energy future.
If you’ve been following the news in the United States this year, you might think that the transition from fossil fuels to renewable technologies has stalled. The narrative of a return to ‘clean coal’ and a bygone era of energy production seems to dominate discussions. However, this perspective overlooks a significant and ongoing shift in the energy landscape.
The recent legislation signed into law, often referred to as the “One Big Beautiful Bill,” appears to undermine progress in clean energy expansion. This bill could potentially damage many clean energy projects that benefited from incentives in the Inflation Reduction Act passed by the previous administration. However, the fundamental flaw in this strategy is that the push for renewable energy is driven by economic factors rather than ideology.
Investors and developers are increasingly turning to renewable technologies because they are more reliable, affordable, and quicker to deploy than fossil fuel alternatives. For instance, according to Lazard, a respected financial advisory firm, the unsubsidized Levelized Cost of Energy (LCOE) for utility-scale solar photovoltaic power in the U.S. is now lower than that of the cheapest fossil fuel electricity generation methods, such as Combined Cycle Gas Turbine (CCGT) power stations. Even when energy storage is factored in, solar remains competitive.
Onshore wind follows a similar trend, with costs remaining favorable compared to fossil fuels. Reports from various reputable organizations, including the International Energy Agency and the U.S. Energy Information Administration, confirm that solar PV LCOE is lower than CCGT in most regions, even without tax credits.
The urgency of transitioning to renewable energy cannot be overstated. The faster a project is completed, the less interest accrues on capital investments, and the sooner returns can be realized. Data from the Solar Energy Industries Association (SEIA) indicates that a typical utility-scale solar park can be operational in as little as 17 months, while onshore wind farms take about 20 months. In contrast, fossil fuel power stations often take four years or more to become operational, with nuclear plants taking over a decade.
In 2024, solar power and energy storage accounted for 84% of all new U.S. electricity grid capacity, with 50 gigawatts of solar PV installed—the largest growth in over two decades. Projections indicate that solar, wind, and batteries will comprise 99% of all new energy installations this year. The rapid growth of solar power is reminiscent of the explosive growth fossil fuels experienced in the early 20th century.
Interestingly, Texas, a state often associated with fossil fuels, is leading the charge in solar energy installation. It is projected to add nearly 10 gigawatts of new solar capacity this year, surpassing California in utility-scale solar capacity. This shift is driven not by environmental concerns but by economic incentives.
Since the Inflation Reduction Act, U.S. solar module manufacturing capacity has increased nearly fourfold, meeting almost all domestic demand. This growth not only creates jobs but also leads to healthier communities. Reports indicate that areas powered by solar energy experience fewer asthma attacks and clearer skies. In 2022 alone, wind and solar energy prevented between 1,200 and 1,600 premature deaths due to reduced emissions, saving an estimated $249 billion from 2019 to 2022.
A recent poll revealed that 87% of Americans support federal incentives for solar and energy storage deployment, including 78% of those who voted for the current administration. Despite this overwhelming support, the current administration seems intent on dismantling progress in renewable energy, driven by ties to fossil fuel industries.
As Bill McKibben noted, the war on wind and solar will ultimately fail because economic forces favor clean energy. In a recent address, UN Secretary General Antonio Guterres highlighted that $2 trillion flowed into clean energy globally last year, outpacing fossil fuel investments by $800 billion. This shift represents not just a change in energy sources but a transformation in possibilities for the future.
On September 21st, a National Day of Action known as Sun Day will take place across the United States. This event aims to demand the rapid deployment of clean energy through rallies, ribbon cuttings for new solar farms, e-bike parades, and public art. Citizens are encouraged to participate by attending events or organizing their own activities to promote clean energy.
If you’re in the U.S., you can find local events and RSVP to participate. Whether it’s hosting a discussion about clean energy improvements or organizing a community march, every effort contributes to the larger movement for change. As the saying goes, even small actions can lead to significant impacts when enough people get involved.
As we stand on the brink of a new era, it is clear that fossil fuels are losing their relevance, and the sun is rising on a clean energy age. The transition to renewable energy is not just a possibility; it is an economic imperative that is gaining momentum across the nation. The upcoming Sun Day event is a testament to the growing demand for clean energy solutions and a call for collective action to ensure a sustainable future for all.
In the words of UN Secretary General Guterres, we are indeed on the cusp of a new era, and it is time to embrace the change that renewable energy brings.
