Solar Soaring: A Bright Outlook for Global Power by 2050

Solar energy is set to exceed previous estimates, potentially constituting over 50 per cent of global electricity by 2050. Declining costs and increasing efficiency position solar as the dominant clean energy source.

FREMONT, CA: Even without strong climate policies, solar energy is expected to exceed earlier projections and could account for more than 50 per cent of the world's electricity production by 2050. The average cost of solar power will significantly drop by 60 per cent between 2020 and 2050 when using a macroeconomic model based on data from 70 regions. Over the last ten years, solar electricity costs have dropped by 89 per cent, while battery prices decreased by the same amount between 2008 and 2022. Solar energy is predicted to be the most affordable choice globally by 2030.

The tipping point for solar power has been reached despite ongoing challenges like managing solar variability and securing critical minerals. This change aligns with the global movement towards net-zero emissions and highlights the incredible progress made in the affordability of clean energy.

The study, which uses a macroeconomic model to synthesise current economic and technological data from 70 regions worldwide, clearly suggests that the solar revolution is underway. Its results indicate that by the middle of the twenty-first century, solar energy will account for more than half of global electricity generation, even without more stringent climate policies.

According to the International Energy Agency's 2022 World Energy Outlook, solar energy will only account for 25 per cent of the world's electricity production by 2050. The study challenges and exceeds previous expectations regarding the shift towards solar dominance, indicating a critical moment in the trajectory of renewable energy.

Solar and Storage Cheapest by 2030

The swift development of solar power is contingent upon two critical elements: its economic viability and expeditious construction schedules. The construction of solar farms can usually be completed in a year, which is significantly less time than the three years that offshore wind farms may require.

In addition to expediting the realisation of cost savings, this quick construction schedule enables investors to take advantage of the financial advantages of solar energy earlier than they would with other renewable energy infrastructures. Due to the self-reinforcing cycle created by this dynamic interaction, producers and installers gain more experience, which lowers prices and increases investor interest in solar energy.

The average cost of producing power from solar energy will drop significantly, with a 60 per cent decrease predicted between 2020 and 2050. Notably, this projection emphasises the long-term appeal of solar energy as a feasible and economical investment by considering the rising demand for energy storage.

By 2030, solar energy and storage are expected to be the most cost-effective way to generate electricity globally. It might be 50 per cent less expensive than developing brand-new coal-fired power plants in strategic locations, creating a competitive obstacle for nations that invest in fossil fuel-based infrastructure and encouraging a move towards sustainability.

The amount of solar energy produced varies greatly depending on the season, time of day, and weather. Grids of electricity must be designed with flexibility in mind to handle this variability. This will necessitate increased investment in complementary renewable energy sources like wind energy, a larger network of transmission cables connecting various regions, and extensive energy storage.

When solar energy takes over in the future, there will be a significant need for several critical minerals and metals. The International Energy Agency projects that 2040 renewable technologies will supply almost 90 per cent of lithium demand, 60 to 70 per cent of nickel and cobalt demand, and 40 per cent of copper demand overall.

More development of recycling programmes will be required to guarantee a consistent future supply of necessary materials. Global mining operations also need to be varied. This will lessen the risk of concentrating mining operations in shaky areas.

Financial support for solar expansion is essential, but most current climate funding goes to developed areas. Using risk-reduction techniques and opening up international finance for developing nations could help close this gap. To remain competitive, countries must embrace renewable energy; to prevent assets from becoming stranded and to welcome the impending era of sustainable energy, they must speed up the integration of solar power.
