On a small island in American Samoa, diesel generators are turning to 100% renewable energy.
The easternmost tau in the archipelago has just been equipped with a new micro-grid, which contains a micro-grid.
4 megawatts of solar energy
Power generation capacity and 6 MW of battery storage.
It is enough to power the entire island day and night.
Tau is only 17 square miles and has a population of less than 1,000 people. so far, they rely almost entirely on diesel generators to generate electricity.
But the situation is not always ideal.
Because the Ta'u is too remote, the fuel for the generator has to be transported by boat, which is expensive, meaning that the fuel on the island is sometimes low before the next shipment arrives.
About a year ago, the American Samoa Electric Power Authority began seeking help on a project that would save the island inconvenience, cost and greenhouse gas emissions from reliance on diesel. “[They]
Basically, just send out the tender to see if anyone can offer a replacement for diesel, which is something we are responding to, "co-
Founder and CTO of solar energy supplier SolarCity, the company was recently acquired by Tesla.
The result is a system consisting of more than 5,000 SolarCity solar panels and 60 Tesla Powerpack battery storage systems.
The new micro-grid can save the island nearly 110,000 gallons of diesel and about 2 gallons a year.
According to U. S. data, 5 million of CO2 emissionsS.

According to Rive, the micro-grid is up and running, covering about 99% of the island's electricity demand.
He added that the battery system could provide the island with full three days of electricity without the sun.
It can be fully charged in seven hours of sunshine.
This is not the first time an island has turned to renewable energy.
Last year, for example, the conservation association completed a $1 investment.
2 million solar and wind projects on Palmira Atoll, about 1,000 miles south of Hawaii.
Although there is no permanent population on the atoll, it is a scientific outpost and temporary residence for researchers.
According to the Association for Conservation of Nature, the island relies almost entirely on renewable energy.

30% of China's electricity comes from wind and solar energy.
A proposed expansion plan announced earlier this year could raise the share of renewable energy to 70%.
The goal is to eventually completely eliminate the use of fossil fuels in the Galapagos Islands.
SolarCity and Tesla are involved in another project on Kauai island, Hawaii, which will complete 17 MW of solar power and 52 MW of battery storage, drive said.
According to Rive, the future of solar energy lies in these types of batteries.
Coupling the system to store and send energy even if the sun does not shine.
One of the biggest obstacles to renewable energy such as wind and solar power is that they can only generate intermittent power.
The sun came out and the wind blew.

Storage solutions are key to the continued expansion of renewable energy.
