10 Reasons Why '100% Renewables Is Possible': Top Energy Experts Issue Declaration
By Jake Johnson
Setting out to rebut defeatist and cynical claims that transitioning the entire global energy system to 100% renewables by 2035 is infeasible, a group of dozens of leading scientists from around the world unveiled a joint declaration Tuesday arguing that such a transformation of the fossil fuel-dependent status quo is not only necessary to avert climate disaster but eminently achievable.
What's required, argue the 46 signatories of the new 10-point declaration, is sufficient political will, international coordination, and concrete action on a massive scale to institute a total "re-design of the global energy system."
"We have lost too much time in our efforts to address global warming and the seven million air pollution deaths that occur each year, by not focusing enough on useful solutions," said Mark Jacobson, director of the atmosphere/energy program and professor of civil and environmental engineering at Stanford University.
"Fortunately, low-cost 100% clean, renewable energy solutions do exist to solve these problems, as found by over a dozen independent research groups," added Jacobson, one of the seven original signers of the declaration. "The solutions will not only save consumers money, but also create jobs and provide energy and more international security, while substantially reducing air pollution and climate damage from energy. Policymakers around the world are strongly urged to ensure we implement these solutions over the next 10-15 years."
The year 2035 has been described by some scientists as the "deadline for climate action" at which humanity "could cross a point of no return" if governments fail to drastically reduce global carbon emissions in the years prior.
The scientists' new declaration, characterized as a concise summary of decades of findings from some of the world's leading energy researchers, argues that a "transformation to 100% [renewable energy] can occur faster than current expectations: the power sector can transform by 2030 and the other sectors soon thereafter."
In addition to helping the world avert catastrophic warming, the researchers argue that such a transformation would also "stimulate investments of trillions of dollars and create millions more jobs than lost worldwide" while providing "sustainable energy security for future generations."
The full 10-point declaration states:
- Numerous studies have investigated 100% renewable energy (RE) systems in regions, countries, and worldwide, and they have found that it works, not only for providing electricity, but also for providing all energy.
- A transformation to 100% RE can occur faster than current expectations: the power sector can transform by 2030 and the other sectors soon thereafter. With political will, a transformation of the global energy sector by 2030-35 appears to be possible!
- Electricity in a 100% RE system will cost less than in our current energy system; the total energy cost of a 100% RE system will be lower than the cost of conventional energy, even if we exclude social costs.
- The total social cost (energy, environmental, climate, and health cost) of a 100% RE system will be drastically lower than of business as usual. The sooner we achieve a 100% RE system, the faster these savings will be realized!
- A 100% RE system can supply regions, countries, and the world reliably (24-7) with energy at low cost.
- A massive re-design of the global energy system will be needed, including increasing energy efficiency on all levels.
- Solar and wind will be the key pillars of energy supply, plus flexibility in many forms, especially storage, sector coupling, demand response management, large- and small-scale grid integration.
- The studies agree that electricity will take a massively increasing share (about 80-95%) of the global energy supply. Electrification will result in a superabundance of cheap clean, renewable energy, increasing prosperity for all humanity.
- All our studies show that creating the new 100% RE system will benefit the world economy. It will stimulate investments of trillions of dollars and create millions more jobs than lost worldwide. Superabundant clean, renewable energy will create wealth and provide a boost for every sector of the global economy.
- Such a rapid transformation is necessary to stop the 7 million human deaths that occur annually today worldwide from air pollution, to slow the growing damage due to global warming and thus avoid the climate catastrophe, and to provide sustainable energy security for future generations.
Stressing the viability of the kinds of transitions that will be necessary to achieve 100% renewable energy across the globe by 2035, the coalition's website points out that:
To date, 11 countries have reached or exceeded 100% renewable electricity; 12 countries have passed laws to reach 100% renewable electricity by 2030; 49 countries have passed laws to reach 100% renewable electricity by 2050; 14 U.S. states and territories have passed laws or executive orders to reach up to 100% renewable electricity by between 2030 and 2050; over 300 cities worldwide have passed laws to reach 100% renewable electricity by no later than 2050; and over 280 international businesses have committed to 100% renewables across their global operations.
"The transformation to 100% renewables is possible," the scientists said, "and will be coming much faster than the general expectation."

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.
Comparing rime ice and glaze ice shows how each changes the texture of the blade. Gao, Liu and Hu, 2021, CC BY-ND
Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
