Solar Power Shines Bright in Texas Heatwave, Debunking Reliability Concerns

As Texas battles a record-breaking heatwave, the state's power grid faces immense strain. Contrary to claims by some lawmakers, renewable energy sources, particularly solar power, have played a crucial role in maintaining energy reliability.

This blog post highlights the importance of solar energy in supporting Texas during the heatwave and debunks misconceptions surrounding its reliability. With a focus on providing valuable insights and optimizing for search engines, we delve into the role of solar power and its contribution to Texas' energy grid.

Solar Power's Determinative Impact on Energy Reliability:

Texas has endured an oppressive heatwave for more than two weeks, with no immediate end in sight. The soaring temperatures have pushed energy demand to record levels, putting strain on the grid. However, the state has managed to avoid rolling blackouts, thanks in large part to its increased supply of solar power. According to Doug Lewin, president of the renewable power consulting firm Stoic Energy, the additional solar capacity has likely been "determinative in making a difference between outages and not having outages" 1. Solar power, especially during hot, sunny summer days, has accounted for over 15% of the state's energy supply, effectively supporting the grid's stability.

Debunking Myths Surrounding Solar Power Reliability:

Despite its proven productivity in Texas, some lawmakers continue to undermine the reliability of solar energy. Critics often argue that solar power is intermittent due to the sun's limited availability throughout the day. However, as Joshua Rhodes, a research scientist at the University of Texas at Austin, explains, "The same sun that heats up buildings... is the sun that can make electricity from solar panels"1. In Texas, solar power remains a reliable and consistent energy source even beyond peak sunlight hours due to the geographical advantage of west Texas, where the sun sets later. By producing electricity until late in the evening, solar power continues to contribute to the grid's stability throughout the day.

Synergy with Other Renewable Energy Sources:

While solar power significantly contributes to energy reliability, it is important to acknowledge the synergistic relationship between different renewable energy sources. Wind power, although less effective during peak electricity demand, complements solar energy by generating electricity in the evening and at night when the sun sets. This combination helps ensure a stable energy supply throughout the day. Additionally, battery storage plays a crucial role by providing immediate backup power when other power sources fail, guaranteeing uninterrupted electricity during critical moments.

Political Rhetoric vs. Data-Driven Analysis:

Despite overwhelming evidence in favor of renewable energy, some Republican lawmakers in Texas persistently demonize renewable sources, often blaming them for grid failures. However, independent reports have consistently debunked these claims, attributing grid failures to the aging fossil fuel power plants rather than renewables. Ed Hirs, an energy fellow at the University of Houston, asserts that the rhetoric against renewables is "clearly politically based" and lacks logical and data-driven arguments1. A data-driven approach is crucial to ensuring the state's grid resilience and addressing reliability concerns.

Urgent Action for a Resilient Grid:

Investing in the reliability of Texas' power grid is essential, especially in light of the climate crisis. Climate change has made extreme heat events, such as the current heatwave, five times more likely in Texas. Without urgent action, the number of scorching days in the state is expected to nearly double by 2036, further straining the grid1. Strengthening the grid's capacity to withstand increasing demands and extreme weather conditions is paramount to ensuring a resilient energy infrastructure.


Solar power has emerged as a reliable and essential component of Texas' energy mix, especially during the ongoing heatwave. By debunking misconceptions surrounding solar energy's reliability, we shed light on its significant contributions to maintaining energy reliability. Texas must invest in the reliability of its power grid, considering the mounting challenges posed by the climate crisis.
