When Elon Musk talks about energy, the world tends to listen — even more so when his warnings sound like something out of a sci-fi thriller. Years after championing solar energy as humanity’s path to survival, Musk is once again in the spotlight — this time not for a breakthrough, but for a billion-dollar controversy. Solar energy has rapidly evolved from an alternative concept to a cornerstone of global energy strategy. According to the International Energy Agency (IEA), solar photovoltaic (PV) technology is now the cheapest source of electricity in history in many regions
Solar energy is the future as the Earth is getting warmer
In 2023 alone, global solar capacity grew by more than 400 gigawatts, accounting for over 60% of all new renewable power installations worldwide. As battery storage improves and installation costs continue to fall — dropping by nearly 90% since 2010 — solar is no longer a futuristic bet, but a proven, scalable solution in the fight against climate change.
At the center of the storm is Tesla’s 2016 acquisition of SolarCity — a move Musk once framed as essential to accelerating the transition to sustainable energy. However, according to shareholders, it wasn’t a visionary leap — it was a bailout. At the time, SolarCity was drowning in debt and bleeding cash. Critics argue that Elon Musk, who chaired both companies, pushed Tesla into the deal to rescue his own investment and protect family members involved in SolarCity’s leadership.
Elon Musk on solar energy
Tesla CEO Elon Musk stressed the importance of home energy independence during the company’s Q4 and full-year 2024 earnings call, suggesting that solar panels and battery storage could be essential for households in the event of grid failures. He described how the solar roof, when paired with the Tesla Powerwall, allows a home to keep running even during extended blackouts — and framed this setup as something that could protect a family’s well-being.
This statement came after Tesla missed both revenue and earnings expectations and reported its first annual sales decline since 2011, despite continued growth in the EV market. While the numbers initially triggered a drop in stock value, shares recovered after the company projected a return to growth.
An investor raised whether Tesla had quietly stepped away from its solar roof product — first introduced in 2016 but slow to scale. Tesla clarified that the product remains a central part of its residential offerings, alongside Powerwall, and still attracts interest. However, it is no longer being installed directly by Tesla. Instead, the company now focuses on manufacturing units for use by roofing industry partners.
Elon Musk’s remarks about solar and backup batteries emphasized how they could help households operate independently of the grid and maintain power during outages — from running appliances to keeping phones and computers charged. He pointed to the convenience and added layer of security this offers, especially during emergencies or long-term disruptions.
While his tone may have leaned toward urgency, the underlying point holds: having solar panels and battery storage can reduce reliance on centralized utilities and keep essential systems online in difficult situations.
Contradictions in Elon Musk statement
Elon Musk supported former President Trump and now serves on a non-binding advisory panel known informally as the “Department of Government Efficiency.” The group holds no regulatory authority, but was created to recommend cost-cutting ideas. Meanwhile, Trump’s energy agenda includes rolling back clean-energy support, including policies that have helped solar grow into one of the fastest-expanding energy sectors in the country.
Musk has also publicly minimized the urgency of climate change. He has suggested that the dangers of global warming are exaggerated — a view at odds with the scientific consensus and growing concerns over extreme weather events linked to climate instability.
