In 1962, a high-altitude Pacific nuclear test caused electrical damage 1,400 km away in Hawaii. A powerful electromagnetic pulse (EMP) – created either by a solar storm or a high-altitude nuclear explosion — poses a threat to regions dependent on electricity, as such pulses could cause outages lasting from two weeks to two years. The main problem is the availability of spare transformers. Superstorm Sandy’s worst effects were in a single location. In the case of a big EMP surge, replacement transformers would be needed in hundreds of locations at the same time. The cost of an EMP pulse to the U.S. economy would likely be in the range of $500 million to $2.6 trillion. A report by the U.S. National Academies was even more pessimistic, guessing at a higher range and a multi-year recovery. Besides disrupting electricity such storms can also destroy satellites, disrupt GPS navigation, and make other parts of the infrastructure fail.

STANFORD, Calif. — AFTER years of hype, renewable energy has gone mainstream in much of the United States and, increasingly, around the world. . .

. . . But many communities that need small-scale renewable energy remain out in the cold — literally and figuratively.

In Alaska, for instance, the vast majority of the more than 200 small, isolated communities populated primarily by native Alaskans rely on dirty, expensive diesel fuel to generate their electricity and heat.

Puerto Rico’s electrical utility is running out of money and time to negotiate a deal with its lenders, part of a broad reckoning for an island that relies on Wall Street to finance some of its most basic functions.

The Puerto Rico Electric Power Authority must repay $146 million to Citigroup over the next two months for a credit line used to buy oil to generate electricity. It is also uncertain whether the authority will be able to renew a $550 million credit line from Scotiabank for fuel purchases, people briefed on the matter said.

Strawberry Energy

In a bid to bring more renewable energy choices to the public, while educating people on the benefits of solar power, one Serbian startup is building public solar charging stations that will energize mobile gadgets and serve as a social hub.

The vision of Strawberry Energy is to make renewable energy sources more accessible for all people, and to show that solar power and other clean energy solutions aren't just abstract concepts, but are instead practical and desirable. The way they're helping to get that message across is through their public solar charging stations, dubbed Strawberry Trees, which offer free charging for mobile devices, and in some cases, free WiFi.
