Island of Tokelau Becomes World's First Solar-Powered Country
By Paul E McGinniss
Goodbye diesel generators, hello sunshine and coconuts! The remote Pacific island nation of Tokelau, which lies midway between New Zealand and Hawaii and was settled over a thousand years ago, is the first country on the planet to give up fossil fuels and power itself solely by renewable resources.
Tokelau's three atolls, which are territory of New Zealand, now have independent renewable energy systems comprised of solar Photovoltaic (PV) panels and coconut biofuel powered generators. Each renewable power plant has battery back up installed and produce enough clean energy to supply 150 percent of the countries current demand.
Previously the island country powered itself by shipping in thousands of barrels of dirty diesel fuel. According to PowerSmart, the New Zealand based company which installed the Tokelau Renewable Energy Project, diesel generators were burning around 200 liters of fuel daily on each of Tokelau's three atolls, meaning more than 2,000 barrels of diesel were used to generate electricity in Tokelau each year, costing more than $1 million NZD. Money saved from diesel fuel costs will now be put toward social programs.
Minister of Foreign Affairs for New Zealand, Murray McCully said in a statement: “Until now, Tokelau has been 100 percent dependent upon diesel for electricity generation, with heavy economic and environmental costs.”
PowerSmart Managing Director Mike Bassett-Smith says the company is proud to be leading the project because of the impact it will have on the well-being of the people of Tokelau:
"All across the Pacific there are clear issues with the current and expected future costs of electricity generated using diesel, not to mention the environmental costs and risks of unloading diesel drums on tropical atolls. ... Energy costs underpin the economic and social development of these nations and making a positive impact on these issues is the single most important reason we started this business."
New Zealand is now working with the pacific nations of Tonga and the Cook Islands to develop renewable energy. And the renewable energy project in Tokelau has generated much interest in renewable energy from New Zealanders as well.
Many countries around the world are announcing aggressive plans for renewable energy development. Saudi Arabia just announced plans to go 100 percent renewable with Mecca working toward becoming the first city in Saudi Arabia to operate an entire power plant from renewable energy sources.
Scotland has set a goal of 100 percent renewable energy by 2020.
In India a climate change movement against fossil fuels has rallied many to embrace clean energy, including the remote village of Sompeta in the state of Andhra Pradesh, to adopt widespread installation of solar PV.
Despite enormous pressure from the heavily subsided, powerful fossil fuels industry, the U.S. has made great strides in developing renewable resources. According to the Renewable Energy Policy Network for the 21st Century, as of 2011 the U.S. was number one in geothermal energy capacity in the world and second in wind power. And we are the fifth largest producer of power from solar PV.
But we have a long way to go if we want to be 100 percent renewable. According to the U.S. Energy Information Agency, approximately 8 percent of U.S. power is now generated by renewable resources. And the U.S. is the second largest consumer of energy, after China, which recently surpassed American energy consumption.
There is an urgent need to combat climate change and get off fossil fuels. Bill McKibben, founder of 350.org, pointed out in his feature piece for Rolling Stone Magazine, "We have five times as much oil and coal and gas on the books as climate scientists think is safe to burn. We’d have to keep 80 percent of those reserves locked away underground to avoid that fate. Before we knew those numbers, our fate had been likely. Now, barring some massive intervention, it seems certain." McKibben is working hard to get these facts out to Americans during his Do the Math Tour.
Fortunately, there's reason for hope. Think Progress reported that renewable electricity nearly doubled under the first Obama administration. And in 2011, global investments in renewable energy surpassed investments in fossil fuels for the first time. Since 2004, one trillion dollars have been invested in the global clean energy sector.
Let's keep the momentum building and keep steady pressure on world leaders, as well as our state and federal governments to push for 100 percent clean energy. Sign EcoWatch's petition today, telling Congress to expedite renewable energy.

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>
