"Too Cheap": Seven Reasons Solar Power Has Surpassed Nuclear Energy

Fortunately, batteries have also undergone their own cost revolution, dramatically enhancing their ability to support solar power development. Roseno said: "Today, in sun-rich regions, the combined cost of solar power plus energy storage is typically already lower than that of building new fossil-fuel power plants. Batteries have essentially solved the daily challenge of shifting solar generation from midday to evening use." For example, in California, solar power and battery storage together met over one-quarter of electricity demand on average during the evening peak hours (7–9 p.m.) in the first half of 2026. Several U.S. states—including Vermont—are now promoting grid-connected home battery systems, typically paired with rooftop solar installations. Nonetheless, Roseno and Jones both note persistent obstacles to storing solar energy across seasons, during prolonged cloudy periods, or throughout monsoon seasons. This underscores the continued importance of integrating solar power fully into the broader electricity system. 6. Comprehensive Electrification Solar power is viewed as a key driver of electrification—helping reduce fossil fuel dependence in sectors previously unconnected to the grid, such as electric vehicles. Electrification was also highlighted as a central topic at this year’s United Nations climate conference in Turkey. Jones stated: "The trajectory for solar is not just to become king of electricity—but king of energy itself." Yet all this requires careful planning. Julia Souder, CEO of the Long-Duration Energy Storage Council—a global, executive-led nonprofit established during COP26—recently warned: "Unplanned electrification carries inherent risks; adding large volumes of new electrical loads without corresponding flexibility makes the entire system vulnerable." In a blog post published by the international policy network REN21, she wrote: "Electrification does not automatically deliver resilience." Roseno noted that today’s constraints on solar expansion are no longer solar panels themselves or their costs—but rather the pace of grid modernization, energy storage deployment, and growth in electrified demand. "The bigger question is no longer whether solar can grow—but whether our power systems and institutions can keep up." Alicia Zhao observed that, in the United States, data centers and electrification are driving electricity demand growth for the first time in decades—and energy security has become a national priority. She said: "Renewables now account for over 90% of newly added U.S. power generation capacity. This demand for secure, rapidly deployable power—even without current federal government support—may create a critical opportunity for further renewable energy advancement." 7. Technological Expansion In recent years, plug-in solar panels—also known as 'balcony solar'—have surged in popularity across Germany. These units generate less electricity than rooftop panels but can feed power directly into homes via standard wall sockets. Currently, several other countries—and some U.S. states, including California—have approved their use. Additionally, agrivoltaics—the integration of agriculture and solar power generation—is increasingly seen in certain regions as a solution to land-use concerns associated with solar farms. Moreover, emerging technologies—from floating solar farms and 'mirror' solar plants to perovskite solar panels and solar windows—could all see significant development in the coming years.

IEA Releases 'Net Zero by 2050: A Roadmap for the Global Energy Sector' — Electrification to Become a Key Tool for Carbon Reduction

Renewable energy sources—primarily wind and solar—will undergo substantial expansion in the future, a view consistently upheld across multiple recent IEA reports. This latest roadmap reaffirms that stance. The report states that a net-zero emissions energy system will rely predominantly on renewables—not fossil fuels. By 2050, fossil fuel use will decline from nearly four-fifths of total global energy supply today to roughly one-fifth. At that point, carbon emissions from fossil-fuel-based products will be concentrated mainly in applications equipped with carbon capture, utilization, and storage (CCUS) facilities. This sharp reduction in fossil energy will be offset by clean energy. By 2050, two-thirds of global energy supply will come from wind, solar, bioenergy, geothermal, and hydropower—with solar becoming the largest single energy source, accounting for one-fifth of total supply. Between now and 2050, photovoltaic (PV) and wind power capacity will increase twentyfold and elevenfold, respectively. Accordingly, the report concludes that solar and wind deployment must accelerate rapidly over the next decade. By 2030, annual PV additions must reach 630 gigawatts (GW), and annual wind additions 390 GW—four times the record set in 2020. For PV alone, that equates to installing a solar park the size of the world’s largest—every single day. The IEA asserts that existing renewable energy technologies are fully capable of meeting the deployment needs of the next decade—and that technological advances will continue driving down the cost of renewable electricity generation. Consequently, electricity will hold a distinct advantage in the net-zero energy transition. Over the next decade, the power sector must eliminate energy poverty for approximately 785 million people currently without electricity access worldwide—and provide clean cooking solutions for 2.6 billion people. Ensuring universal energy access remains integral to implementing the net-zero pathway. Electricity security grows increasingly vital; international cooperation essential to meet challenges As power systems grow cleaner, electrification will become a pivotal tool for carbon reduction across the entire economy. Simultaneously, electricity will assume an even more central role in global energy security than it does today. The report notes that this shift introduces new energy security challenges—including variability in renewable energy supply and cybersecurity risks. Furthermore, growing reliance on critical minerals required for clean energy technologies and infrastructure will heighten exposure to price volatility and supply disruptions—potentially impeding the energy transition. Given these concerns, IEA Executive Director Fatih Birol calls for strengthened international cooperation. Governments must foster markets for batteries, digital grid solutions, and grid investments; encourage system flexibility; and ensure sufficient, reliable electricity supply. New international mechanisms are needed to guarantee timely, sustainable supplies of critical minerals. Over the past year, the number of countries pledging net-zero emissions has grown rapidly—now covering around 70% of global carbon emissions. Alok Sharma, incoming President of the Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC), stated: "International cooperation holds immense value. Without it, the global transition to net zero could be delayed by decades." The urgency expressed by international energy and climate organizations stems from the roadmap’s finding that even if all climate commitments made by governments to date were fully implemented, they would still fall far short of achieving global net-zero emissions by 2050—and limiting global temperature rise to 1.5°C.
