A remote tropical island has catapulted itself headlong into the future by ditching diesel and powering all homes and businesses with the scorching South Pacific sun. Using more than 5,000 solar panels and 60 Tesla power packs the tiny island of Ta’u in American Samoa is now entirely self-sufficient for its electricity supply – though the process of converting has been tough and pitted with delays. Located 4,000 miles from the west coast of the United States, Ta’u has depended on over 100,000 gallons of diesel shipped in from the main island of Tutuila to survive, using it to power homes, government buildings and – crucially – water pumps. When bad weather or rough seas prevented the ferry docking, which was often, the island came to a virtual stand-still, leaving Ta’u’s 600 residents unable to work efficiently, go to school or leave their usually idyllic paradise. Utu Abe Malae, executive director of the American Samoa Power Authority, said Tutuila has subsidized Ta’u diesel shipments for decades to the tune of US$400,000 a year – and continually ran the risk of a serious environmental disaster if the delivery ships capsized during the notoriously treacherous journey.

So what happens when you cross blockchains and internet of things? One outcome is buzzword overload. In the coLAB, we don’t like that very much. We like to make things tangible, and we learn what’s possible by building prototypes.So we built a proof of concept solar panel kit that automatically creates renewable energy certificates as it generates power. Why energy? What are renewable energy certificates? Let us explain.
Kyocera Corporation, K.K. GAIA POWER, Kyudenko Corporation, and Century Tokyo Leasing Corporation announced that the companies have made a joint investment in Kanoya Osaki Solar Hills LLC, a solar power operating company, to construct and operate a 92-megawatt (MW) solar power plant. Planned for construction on a site stretching across Kanoya City and Osaki Town in Kagoshima Prefecture, the project will become one of the largest solar installations in Japan.
Project planning began in January 2014, as the local community expressed interest in effectively using the project site, which had been designated for a golf course more than 30 years ago but subsequently abandoned. Covering a total of approximately 2,000,000m2 (approx. 494 acres), the site will accommodate 340,740 Kyocera solar modules, and is expected to generate roughly 99,230MWh annually — enough electricity to power approximately 30,500*1 typical households, offsetting roughly 35,730 tons of CO2 emissions per year
“We are at the beginning of a new era in power markets,” the UBS analysts write. ”Purely based on economics, we believe almost every family home and every commercial rooftop in Germany, Italy and Spain should be equipped with a solar system by the end of this decade.” It says up to 18% of electricity demand could be replaced by self-produced solar power in these markets, at the expense of centralised generation. Even as soon as 2020, up to 43GW of unsubsidised solar could be installed in Germany, Italy and Spain, replacing up to 9 per cent of electricity demand. This is on top of reduction in demand caused by energy efficiency measures and weak GDP growth.
If Germany succeeds in making the transition, it could provide a workable blueprint for other industrial nations, many of which are also likely to face pressures to transform their energy consumption. “This Energiewende is being watched very closely. If it works in Germany, it will be a template for other countries,” says Graham Weale, chief economist at RWE, which is grappling with how to shut its nuclear power plants while keeping the lights on. “If it doesn’t, it will be very damaging to the German economy and that of Europe.”
