Most of The World Could Be 100% Powered With Renewables by 2050

Almost three quarters of the world’s countries could be powered entirely by renewable energy sources by 2050 – if we want it badly enough, that is.

That’s according to an ambitious new 2050 roadmap that calculates a move to an emissions-free future would create millions of jobs, cut trillions in health and climate costs, and help save the planet from global warming.

The estimates, produced by a team of almost 30 scientists, are based on an assessment of the capabilities of 139 countries to transition to 100 percent wind, water, and solar power in the next three and a bit decades.

While such a far-reaching overhaul of existing energy infrastructure goes beyond what the UN’s Paris climate agreement (COP21) actually calls for, the researchers say there are compelling reasons for going all in sooner rather than later.

“Our findings suggest that the benefits are so great that we should accelerate the transition to wind, water, and solar, as fast as possible,” says one of the team, Mark Delucchi from the University of California, Berkeley, “by retiring fossil-fuel systems early wherever we can.”

That’s because doing so wouldn’t just create new jobs in renewables – a net increase of more than 24 million full-time positions is anticipated – it would also make us healthier sooner, with less fossil fuel emissions polluting the atmosphere.

The team says that reduction alone could cut deaths due to air pollution by as much as 4.6 million premature fatalities annually.

But perhaps even more importantly in the long run, making the switch could lock in COP21’s goal of keeping the rise in global temperatures to less than 1.5 degrees Celsius above pre-industrial levels.

The research, which in an earlier form was initially presented to world leaders at COP21 in 2015, builds upon a previous US-only roadmap that showed how the 50 US states could make the same kind of renewables transition by 2050.

Both studies were spearheaded by Stanford University’s Mark Z. Jacobson – a co-founder of US non-profit The Solutions Project.

“What I find most exciting about the results of this study is that every country that we examined has sufficient resources to power itself,” he told Charles Q. Choi at IEEE Spectrum.

“[A]lthough in the case of a couple of tiny countries with very high populations, this might require either importing energy from their neighbor or using an unusually high amount of offshore energy.”

That’s because larger countries with more landmass respective to the size of their populations enjoy greater flexibility in finding appropriate sites for solar, wind, and hydropower facilities.

While the 139-country roadmap has been a massive undertaking, the team don’t intend to stop there.

“We are next developing roadmaps for individual cities to go to 100 percent clean, renewable energy,” Jacobson said.

While thousands of the world’s cities are already doing an amazing job of independently crushing their carbon emission targets, more localized and granular roadmaps could only help the world to go emissions-free.

As awesome as the rapid uptake of renewables has been in recent times, from where we stand right now we’ve still got a long way to go to get to 100 percent – but we’ve got a roadmap, people, and we know which way to head.

The findings are reported in Joule.

Saint Petersburg Becomes First Florida City to Commit to 100% Renewables

The Saint Petersburg City Council formally approved on Monday the city’s commitment to transitioning to 100 percent clean, renewable energy. Saint Petersburg represents the first city in Florida and the 20th city in the country to make such a commitment.

In a unanimous vote, the City Council Committee of the Whole allocated $250K of BP Oil Spill settlement funds to an “Integrated Sustainability Action Plan,” which will chart a roadmap to 100 percent clean, renewable energy in Saint Petersburg. In addition, the plan also incorporates components of a climate action plan, a resiliency plan and strategies for Saint Petersburg to achieve a 5 STAR Community rating. The 100 percent clean energy roadmap builds on Mayor Rick Kriseman’s executive order establishing a net-zero energy goal for the city earlier in 2016.

“The movement for clean energy in cities and towns across the country is now more important than ever,” Sierra Club Executive Director Michael Brune said.

“Saint Petersburg joins 19 other cities from San Diego, California to Greensburg, Kansas that will lead the way to support equitable and inclusive communities built on 100 percent clean, renewable energy for all. Whether you’re from a red state or blue state, clean energy works for everyone and local leaders will continue to move forward to create more jobs, stronger communities, and cleaner air and water.”

Mayor Kriesman will share more information on the Integrated Sustainability Action Plan at a press conference on Dec. 9 on the steps of City Hall. The chancellor of the University of South Florida St. Petersburg will also make an announcement about the university’s recently-completed climate action plan.

“The Integrated Sustainability Action Plan builds on my executive order on sustainability by creating a roadmap to achieve the city’s long-term sustainability goals,” Mayor Kriseman said. “Working towards 100 percent clean energy and zero waste will help ensure that St. Pete remains a ‘city of opportunity where the sun shines on all who come to live, work and play.”

Organizations that support the Ready for 100% St. Pete campaign include Oceana, Environment Florida, Southern Alliance for Clean Energy, Sunshine State Interfaith Power & Light, Keep Pinellas Beautiful, LocalShops1, Center for Biological Diversity, Chart 411, Craftsman House, The Burg Bar & Grill and St. Peace House.

“This is a historic moment for St. Pete,” Emily Gorman, campaign manager for Suncoast Sierra Club’s Ready for 100% St. Pete, said. “We envision a city where families can raise their kids in communities free from toxic pollution, where everyone has the opportunity for a good job and access to healthy, affordable energy. The transition to 100 percent clean, renewable energy will ensure a more resilient, sustainable and equitable future for all our residents.”
