San Francisco Board of Supervisors votes unanimously to ban gas in new buildings

San Francisco has already banned natural gas for any new city-owned building. Berkeley banned gas in new buildings last year. Natural gas accounts for roughly 40% of San Francisco’s overall emissions of greenhouse gases and 80% of building emissions. Requiring cleaner, all-electric buildings in new construction will increase building safety, reduce emissions citywide, and improve indoor air quality, Mandelman said. …

Tony Seba RethinkX findings on rapid electricity decarbonization and ramp-up of renewables

» It is both physically possible and economically affordable to meet 100% of electricity demand with the combination of solar, wind, and batteries (SWB) by 2030 across the entire continental United States as well as the overwhelming majority of other populated regions of the world. » The Clean Energy U-Curve captures the tradeoff relationship between electricity generation and energy storage …

Griffith: If households were to electrify everything from their cars to their heaters, backed by renewable energy sources, they could cut their energy bills by a third and save $1,050-$2,585 per year – even after the cost of financing the switch

We’ve often heard that decarbonizing our households, by switching all our fossil-fueled machines to electric ones, would be prohibitively expensive. But Rewiring America’s new study, No Place Like Home: Fighting Climate Change (and Saving Money) by Electrifying America’s Households, by Saul Griffith, PhD and Sam Calisch, PhD, offers hope and highlights an opportunity. If households were to electrify everything from …

How Sweden Is Transforming Homes Into Power Stations

One example is in the city of Ludivika where 1970s flats have recently been retrofitted with the latest smart energy technology. 48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight. The result is a cluster of ‘prosumer’ …

Energy footprints grow with expenditure: the top 10% consume roughly 20 times more energy than the bottom 10%

A study published in Nature Energy shows that energy footprints grow with expenditure, and, as a consequence, are unequally distributed. Among all the countries and income classes in the study, the top 10% consume roughly 20 times more energy than the bottom 10%. Additionally, as income increases, people spend more of their money on energy-intensive goods, such as package holidays or …
