- “’Seismic Shift:’ Energy Crisis Helped Wind And Solar Stretch Cost Advantage Over Fossil Fuels” • In 2010, the cost of solar PV was eight times as high as the cheapest source of fossil fuels, with a levelised cost of energy of 44.5¢/kWh. An IRENA report says the LCOE of PVs fell to 4.9¢/kWh in 2022, making it 29% cheaper than the cheapest fossil fuel option. [Renew Economy]
- “Heat Pumps Up To Three Times More Efficient In Cold” • A study from Oxford University and the Regulatory Assistance Project used data from seven field studies. It shows that heat pumps are two to three times as efficient as combustion or resistive electric heating technology, even in temperatures approaching -30°C (-22ºF). [CleanTechnica]
- “Number Of Billion-Dollar Weather Disasters In US Blows Through Annual Record With Four Months Left In The Year” • With four months left in the year, the US has had 23 disasters that each cost at least $1 billion, NOAA data shows, surpassing the previous record of 22 events in 2020. Together, 2023’s disasters have done $57.6 billion in damages. [CNN]
- “Sun Cable Plan To Bring Solar Power To Singapore Is Back On” • Sun Cable, formerly known as PowerLink, is an ambitious idea that involves sending solar power via an undersea cable 4,200 km (2,610 miles) from Darwin, Australia, to Singapore. Delays in approvals and disagreements held the project up. Now it is under way again. [CleanTechnica]
- “Record US Small-Scale Solar Capacity Added In 2022” • The Energy Information Administration estimates that the US added a record 6.4 GW of small-scale solar capacity in 2022. Capacity grew from 7.3 GW in 2014, the first year of estimates, to 39.5 GW in 2022. Small-scale solar makes up about one-third of the total solar capacity in the US. [CleanTechnica]
