A groundbreaking study conducted by researchers from the Karlsruhe Institute of Technology in Germany has unveiled that more than 30 million homes in Europe could potentially fulfill all their energy requirements using rooftop solar panels.
The study identified that over 50% of Europe’s 41 million freestanding homes could have achieved self-sufficiency in 2020 using only solar power and batteries, a percentage expected to rise to 75% by 2050.
The findings, presented in the study titled ‘Two million European single-family homes could abandon the grid by 2050’, published in the scientific journal Joule, underscore the significant decrease in solar panel costs. The price of solar panels has plummeted by nearly 90% over the past decade, making solar power increasingly affordable and accessible, according to Independent.
Lead researcher Felix Creutzig noted that these falling costs could pave the way for solar technology and other renewables to feasibly and cost-effectively cover the world’s entire energy consumption by 2050.
In a related study published last month by researchers from the University of Exeter and University College London, solar energy was identified to have reached an “irreversible tipping point.” This development is expected to propel solar power to become the primary global energy source within the next thirty years, marking a significant shift away from fossil fuels.
