Quiet, clean and green are not words you would typically use to describe a construction site. But the site at Olav Vs gate, one of the busiest streets in the heart of Norway's capital city, Oslo, was special. In a first of its kind in the world, all the machinery used on site – excavators, diggers and loaders – were electric.

HO CHI MINH CITY/SEOUL -- Samsung must switch to using 100% renewable energy in South Korea and Vietnam -- the tech conglomerate's two biggest production bases -- even as those countries plan to build more coal-fired power plants, Greenpeace said in a report on Tuesday.

In the tranquil Greek island of Tilos, a wind turbine hums over a silvery sea while scorching sun rays hit a hill lined with solar panels. The small island of around 800 inhabitants is the first island in the Mediterranean to generate almost all of its electricity from renewable sources under a pioneering project launched in 2018.

“Our technology is going to complement the current forms of printed, back-lit communication,” says Jeroen ter Schiphorst, Chief Technology Officer and co-founder at Lusoco. The company is initially focusing on sustainable advertising signs. This is because these kinds of signs consume a significant amount of energy, about three hundred to six hundred kilowatt hours per piece annually. “Of course, we are using more and more renewable energy, but our demand for energy will also increase significantly in the years to come, for example due to the rise of electric cars,” Ter Schiphorst explains.

China's industrial hub Shandong province pledged to tighten new approval of industries such as oil refining and aluminium smelting which have high energy use and high emissions as Beijing strives to meet climate change targets.

Japan on Monday pledged to offer $10 billion financial aid for decarbonisation projects in Asia, such as renewable energy, energy-saving and conversion to gas-fired power generation from coal-fired power to help with an energy transition.

An energy transition zone in Aberdeen is being allocated £26m by the Scottish government to help the transition from oil and gas jobs to green energy. This almost matches funds provided by the UK government. The zone aims to transform the area into a hub for cleaner energies such as offshore wind and hydrogen.

Ever since President Xi Jinping pitched the idea of a “global energy internet” to the United Nations six years ago, China’s been trying to persuade the world to build the high voltage highways that would form its backbone.

As part of Beijing's carbon reduction goals, China's traditional fossil fuel giants are racing to take the lead in hydrogen energy, cities are making plans to develop it as a clean power source, and automakers are developing hydrogen-driven vehicles.

Indonesia aims to sell only electric cars and motorcycles by 2050 to replace vehicles powered by combustion engines, the country's energy minister said on Monday, as the Southeast Asian country seeks to reduce its carbon emissions.

Scottish energy company Nova Innovation has created the first ever electric vehicle charge point using a source of tidal energy, on the island of Yell in Shetland. Tidal energy is an abundant renewable source on a planet covered by 70% water yet remains largely untapped.

The world’s longest undersea electric cable is set to be switched on this week, as testing begins for the 720km interconnector that will trade power between the UK and Norway. Electricity will start flowing through the €2bn North Sea Link in coming days, with the joint venture between the UK’s National Grid and Norway’s Statnett due to begin formal operations in October.
