Pay-per-use approaches to air conditioning and more
In your office you may have a photocopier which is leased on a pay-per-use basis. The same approach is being applied in the cooling industry. The idea of Cooling as a Service (CaaS), enables customers to leap-frog to the best solutions available in their markets, while incentivising suppliers to improve maintenance, increase efficiency, reduce energy use, maximise the use of equipment & reutilisation of components. Today, CaaS is saving more than 68 GWh of electricity & 36,000 tonnes of CO2 emissions annually ( = 50,000 return flights from London to New York) Win:Win 4 planet, consumers & business.
Aircraft looking "tidal kites" will generate electricity from the ocean's tidal power, as tested out at the Faroe Islands over the past year as they provide power to the islands.The technology has been developed by Swedish engineering firm Minesto, with larger versions of the tidal kites being rolled out in 2022.To find more, click the link:https://www.bbc.com/news/business-59401199
The paper industry is energy-intensive. According to the EIA, the industry consumed 1483.2 trillion British thermal units (Btu) of energy in 2019. At the same time, the CO2 emissions of the paper industry
reached 48 million tons. Utilising renewable energy is a well established way to try to reduce the emissions footprint of processing steps reliant on electricity. But replacing natural gas needed for high temperature drying is harder. In what could well be a world-first, a NZ company is replacing natural gas in its drying hood with geothermal steam instead. https://www.eeca.govt.nz/about/news-and-corporate/news/essitys-groundbreaking-geothermal-project-a-world-first/
Science Direct forecasts worldwide solar PV waste will to reach around 78 million tonnes by 2050. Recovery of materials such as silicon has traditionally needed hydrofluoric acid, a highly toxic and corrosive chemical. Scientists have found a new way to recover silicon which uses a specific chemical treatment sequence, using less toxic chemicals. The process delivers a silicon purity of 99.9984%, recovers more useful materials than just silicon and delivers a profit of $185 on every 1kg of solar panel recycled in this manner.https://www.saurenergy.com/solar-energy-news/indian-scientists-recover-pure-silicon-from-obsolete-solar-cells
