Today’s Solutions: December 19, 2025

In an attempt to show that transitioning to a global 100 percent renewable energy system is no longer a matter of technical feasibility or economic viability, but one of political will, a Finnish university has published a comprehensive global roadmap on how the world can reduce its carbon emissions before the 2050 deadline. The report breaks down exactly how the world’s different regions can transition to 100 percent clean energy as a means of preventing the more catastrophic outcomes of irreversible climate change. The study is the first of its kind to outline a cost-effective international strategy to keep the planet’s carbon emissions at 1.5. degrees Celsius. Not only that, it is the first one of its kind to suggest a global strategy that does not involve carbon-capture technology. As of right now, one-third of the world’s energy is renewable. With population growth and energy demand in mind, the researchers say that we could meet the Paris Agreement’s carbon mitigation goals by generating 69 percent of the world’s energy from solar panels, 18% from wind power, 3% from hydropower and 6 percent from bioenergy. Additionally, all the energy transitions could be paid for simply by giving up on fossil fuels entirely. The researchers dedicated the report to 16-year-old climate activist Greta Thunberg, who has been nominated for the Nobel Peace Prize in recognition for her youth-led Fridays for Future environmental protests.
