Solar cell efficiency may get a bump from bumps. New research from Turkey’s Abdullah Gül University suggests that building tiny domes into the surface of organic solar cells could boost their efficiency by up to two-thirds, while capturing light from a wider angle.
The city’s new Bicycling Rewards Program aims to encourage community members to ride a bike instead of driving. The program comes as a response to the city’s lagging climate goals. According to Denver Streets Partnership, transportation was responsible for 30% of the city’s greenhouse gas emissions in 2018, and this incentive is part of a larger research project to see what motivates locals to ditch their cars.
This year’s Super Bowl was the first ever to be fully powered by renewable energy, thanks to the host stadium’s agreement with a solar farm. More than 621,000 solar panels found in a barren area of the Nevada desert help power Allegiant Stadium, home to the Las Vegas Raiders and host of Super Bowl LVIII. According to CBS News, the Les Vegas stadium entered into a 25-year agreement with NV Energy to buy power from its new solar installation.
A remarkable pilot project installed on a 787-ft. container ship has proven it’s possible to capture emissions from the smokestacks of cargo ships with 78% efficiency and convert the CO2 into limestone pebbles, which can be offloaded and sold. London startup Seabound, funded by a US$1.5-million grant from the UK Government, partnered up with global shipping company Lomar to install the carbon capture equipment on one of its older and dirtier-burning ships, a medium-sized vessel capable of carrying more than 3,200 shipping containers.
Nine U.S. states have inked an agreement to promote climate-friendly heat pump sales. The memorandum of understanding sets a 2030 target for heat pumps to make up 65% of residential heating, cooling, and water heating equipment sales. By 2040, the goal is for heat pumps to account for 90% of the HVAC and water heating market. The states on board with the agreement include: California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island.
The European Union saw a record drop in fossil fuel power last year, according to a new analysis by energy think tank Ember. In 2023, coal generation fell by 26%, while gas generation fell by 15%. Along with a record buildout of renewables and a downturn in demand, the decline of fossil fuels led to an unprecedented drop in emissions from generating electricity, which fell by 19%. Now, for the first time, wind power supplies more electricity for Europe than either natural gas or coal.
Around the world, mangrove forests have undergone a decades-long decline that’s just now slowing to a halt. But Pakistan bucks this trend. The country’s mangroves expanded from 48,331 hectares in 1986 to 143,930 hectares in 2020, according to a 2022 analysis of satellite data. Many in Pakistan are looking to mangroves to bolster precious fish stocks and defend against the mounting effects of climate change.
Ethiopia is to claim the accolade of becoming the first country in the world to ban the importation of all internal combustion engine cars, both new and used. The East African country will adopt an electric-only strategy as it seeks to reduce its reliance on fossil fuel imports and clean the air in its cities. While EV charging infrastructure is limited, Ethiopia does generate 100% of its electricity from renewable sources, according to the International Energy Agency, with strong solar, hydropower, and wind power projects.
As of January 2024, municipalities in France must now provide residents with ways to sort bio-waste, which includes food scraps, vegetable peels, expired food and garden waste. Households and businesses are required to dispose of organic matter either in a dedicated small bin for home collection or at a municipal collection point. The waste will then be turned into biogas or compost to replace chemical fertilizers.
Electric vehicles sales in China, the world’s largest automotive market, are surging. All plugin models accounted for 37% of the market in 2023, up from just 6% at the end of 2021. Full electrics (BEVs) alone accounted for 25%. Plugins are expected to cross the 50% mark for plugins and electric by 2026, with BEVs likely to account for over a third of sales, if current trends persist.
