U.S. investors are beginning to smell an opportunity in the waste-to-energy market, where livestock dung and food garbage is traded. Interest is being fueled by new state laws and by demand from companies such as UPS Inc.

After a lull in investor interest stretching back a decade, attention to “anaerobic digestion” waste-to-energy is surging in the United States, developers in the sector have said. — The Los Angeles Times

The desert outside Tennant Creek, deep in the Northern Territory, is not the most obvious place to build and transmit Singapore’s future electricity supply. Though few in the southern states are yet to take notice, a group of Australian developers are betting that will change. If they are right, it could have far-reaching consequences for Australia’s energy industry and what the country sells to the world. — The Guardian

Nearly 300 coal-fired power plants have been "retired" since 2010, according to the Sierra Club. It's a trend that continues despite President Trump's support for coal. That has left many communities worried that those now-idled places will simply be mothballed. — NPR

The dream of nuclear fusion is on the brink of being realised, according to a major new US initiative that says it will put fusion power on the grid within 15 years.

The project, a collaboration between scientists at MIT and a private company, will take a radically different approach to other efforts to transform fusion from an expensive science experiment into a viable commercial energy source. — The Guardian

Britain’s homes could be lit and powered by windfarms surrounding an artificial island deep out in the North Sea, under advanced plans by a Dutch energy network.

The radical proposal envisages an island being built to act as a hub for vast offshore windfarms that would eclipse today’s facilities in scale. Dogger Bank, 125km (78 miles) off the East Yorkshire coast, has been identified as a potentially windy and shallow site. — The Guardian

Permissive building codes, industry inertia, and market demands — like clients clamoring for floor-to-ceiling views — have widened the discrepancy between the kind of buildings cities say they want and what they actually allow. So while the industry inches towards better environmental performance, buildings in Boston and other cities still fall short of the sustainability goals that everyone claims to embrace. — The Boston Globe

Google parent Alphabet is spinning off a little-known unit working on geothermal power called Dandelion, which will begin offering residential energy services. [...]

Dandelion chief executive Kathy Hannun said her team had been working for several years "to make it easier and more affordable to heat and cool homes with the clean, free, abundant, and renewable energy source right under our feet," and that the efforts culminated with the creation of an independent company outside of Alphabet. — phys.org

Driverless cars will trundle around the UK in their first public trials today.

The demonstration of the autonomous electric vehicles is going to take place on the pavements of Milton Keynes.

These tests will be the culmination of an 18-month research project which involved virtually mapping the town and updating regulations for driverless vehicles. — Sky.com

Renewable energy like solar and wind is booming across the country as the costs of production have come down. But the sun doesn't always shine, and the wind doesn't blow when we need it to. [...]

A company called SolarReserve may have found a solution: It built a large solar plant in the Nevada desert that can store heat from the sun and generate electricity for up to 10 hours even after sundown. — npr.org

A US government agency says it has attained the “holy grail” of energy – the next-generation system of battery storage, that has has been hotly pursued by the likes of Bill Gates and Elon Musk.

Advanced Research Projects Agency-Energy (Arpa-E) – a branch of the Department of Energy – says it achieved its breakthrough technology in seven years. — The Guardian

According to a team of researchers at MIT, both scenarios may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat, whenever it’s needed. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.

[...] the new finding could provide a highly efficient method for storing the sun’s energy through a chemical reaction and releasing it later as heat. — news.mit.edu

The rainy season coincides with summer in Dakar, which means it’s the power-cut days. The heat goes up, A/Cs kick into gear and the power utility, Senelec, cannot cope. [...]

Enter solar. This potential renewable savior is a latecomer to Dakar because until recently solar power was banned in cities, as it was considered what the French pointedly call “compétition déloyale” – unfair competition.

But under pressure from Dakar’s own citizens, the ban was lifted under the last government [...]. — nextcity.org

China has announced plans to ban the use of coal in its smog-plagued capital by the end of 2020, as the country fights deadly levels of pollution, especially in major cities.
Beijing's Municipal Environmental Protection Bureau posted the plan on its website on Monday, saying the city would instead prioritize electricity and natural gas for heating.
The Chinese central government recently listed environmental protection as one of the top criteria by which leaders will be judged. — Al Jazeera
