  • Green ammonia at 10 ports could decarbonise most of shipping

    Green ammonia is a fuel made through a 100 per cent renewable and zero-carbon processes, such as combining hydrogen from water electrolysis and nitrogen separated from the air through a renewables-powered Haber process. It has been proposed as an alternative fuel source for the shipping industry, although there has long been uncertainty about how and…

  • Fixing the Panama Canal

    A reduction to 24 ships per day from the normal 38 doesn’t sound like a lot, but that’s a 36% loss in annual Canal traffic. Imagine the East Coast without 17% of its Asian-sourced fuel and goods, or having to bear the cost of rerouting that traffic through thousands more miles at sea.

  • How the US is rapidly cleaning up its biggest form of mass transit

    The US Environmental Protection Agency (EPA) has now allocated enough funds to replace more than 5,000 of the country’s school buses with zero-emission alternatives.

  • Scientists drilling into magma chamber for potentially unlimited energy

    Scientists in Iceland are steaming ahead with an ambitious project to drill straight down into a magma chamber that could provide not only the first direct look at the oceans of molten rock stewing miles beneath the Earth’s surface, but a revolution in geothermal energy that could potentially see the technology be used anywhere on…

  • ‘World’s largest solar project’ breaks ground in PH, says SPNEC

    The project aims to have 3,400 megawatts of solar panels and 4,000 megawatt hour (MWh) of battery storage. This alone costs P200 billion, SPNEC said.  Once finished, the firm said it would generate around 5 billion kilowatt-hour (kWh) yearly “or an estimated 5% of the total volume of the Philippine grid and 12 percent of…

  • BIG’s mindfulness city in bhutan envisions the world’s first carbon-negative community

    In the expansive area of Gelephu, the existing natural landscape and infrastructure have naturally given rise to eleven distinctive neighborhoods. These areas are meticulously planned, drawing inspiration from the Mandala principles. Each neighborhood is centered around a communal space, with a gradual shift from scattered smaller buildings in the northern region to more substantial urban…

  • China’s Decarbonization Efforts Gain Momentum

    Renewable energy capacity hit a record high of 1.45 billion kilowatts by mid-December 2023, for the first time exceeding thermal power and representing over half of China’s energy mix, with wind and solar as major drivers. https://shanghaiist.com/chinas-decarbonization-efforts-gain-momentum/

  • Perovskite Solar Cell Mystery Solved, Now Comes The Hard Part

    If you’re wondering why perovskite solar cells are not yet widely available 14 years after that first paper was published, that’s a good question. Silicon is a more expensive energy-capturing material, but its durability has made it the go-to photovoltaic material of choice. Perovskites are relatively inexpensive, but they are unstable. Their crystalline structure shifts…

  • A climate change poem turned hip-hop song.

    “Hip-hop being a voice for the voiceless, this was an opportunity for me to give a voice for the environment.” https://www.teaonews.co.nz/2023/12/22/a-climate-change-poem-turned-hip-hop-song/

  • EVs and hybrids had a noticeable effect on US fuel consumption, says EPA

    For MY2022, the EPA says that the average real-world CO2 emissions for all new vehicles fell by 10 g/mile to 337 g/mile, the lowest average it has ever measured. Similarly, real-world fuel economy increased by 0.6 mpg for MY2022, to 26 mpg—this, too, is a record high and the single-largest year-on-year improvement for both CO2 and mpg…
