Martin Hannan for The National: HOUSEHOLDERS on the Shetland Isles were not aware of it, but when they plugged in their kettles recently, they were sharing in a bit of history.
For the Shetland Tidal Array at Bluemull Sound, installed by Nova Innovation of Edinburgh, has become the world’s first tidal power array to be connected to a grid and deliver power on a commercial basis – to dozens of homes on the islands.
The achievement has been hailed by environmentalists and the renewable industry as a turning point in the development of marine power.
Nova had shown its technology could work with a single turbine which generated electricity in March. But the installation of second turbine that is also working to the grid proves that large tidal power arrays can and do work. Commercially viable tidal power is seen as something of a Holy Grail by the industry, since it is one of the few renewable energy sources that is entirely predictable – as one industry source once put it: “there will be tidal power available as long as the moon is in the sky”.

Anjana Pasricha for VOA News: Indian scientists have designed a “solar tree” that they hope will help overcome one of the key challenges the country faces in the generation of solar power.
With photovoltaic panels placed at different levels on branches made of steel, “solar trees” could dramatically reduce the amount of land needed to develop solar parks.
“It takes about four-square meters of space to produce energy which otherwise would have required 400 square meters of space. So almost 100 times the space is saved, which as you know is very valuable,” said Daljit Singh Bedi, chief scientist at the Council of Scientific and Industrial Research (CSIR) in New Delhi, whose laboratory in Kolkata developed the tree.
A scarce resource in India, acquisition of land to develop roads, factories and other infrastructure is a sensitive issue that has led to frequent and sometimes violent protests from displaced people. Cont'd...
Louis Sahagun for The LA Times: The San Bernardino County Board of Supervisors has rejected a controversial solar plant proposed for the Mojave Desert’s Soda Mountains, citing concerns that the project would destroy habitat and block ancient trails used by bighorn sheep for thousands of years.
In a 3-2 vote, the board on Tuesday declined to certify documents required under state law in order to issue county permits for the project on public land along Interstate 15 near the entrances to Joshua Tree National Park and Death Valley National Park, and less than a mile from the Mojave National Preserve.
“We endorse renewable energy, but this was the wrong project in the wrong location,” said Supervisor Robert A. Lovingood. Cont'd...
