We can’t afford not to decarbonize. Invest 1% of world GDP, the total value of all goods and services in the world = about $85 trillion per year in 2019. 1% of that is $850 billion/yr

From Dr. Scott Denning, Colorado State University, Aug 2019 Economists estimate the total cost of decarbonizing the world economy to be about 1% of global GDP. Academic economists estimate the total cost of saving our descendants from millennia of hellish struggle at 1% of GDP (plus or minus 1% — could actually cost anywhere from nothing to 2%). And yes …

Mass-production techniques + aggregated demand among building owners to cost-effectively retrofit buildings to a net-zero energy standard

The Challenge of Scaling Up Energy Retrofits for Buildings Most building energy retrofits are one-off affairs. “We need an Amazon” in the market, says one architect. By Tom Konrad, GTM, July 19, 2019 Getting to the root of the problem.8 It’s almost always easier and cheaper to build an energy-efficient building in the first place than retrofitting existing structures. But …

New York’s climate plan will drive big changes, if it works

Solar panels on every roof. Parking meters that double as car chargers. Wind turbines towering above farm fields and ocean waves. A new law signed Thursday by New York Gov. Andrew Cuomo sets the nation’s most aggressive targets for reducing carbon emissions and is intended to drive dramatic changes over the next 30 years. It calls for all the state’s …

Fossil fuel EROI for electricity close to 3:1

Science Daily, July 2019: Researchers have calculated the EROI for fossil fuels over a 16 year period and found that at the finished fuel stage, the ratios are much closer to those of renewable energy sources — roughly 6:1, and potentially as low as 3:1 in the case of electricity. An evaluation of the global energy return on investment for …

Researchers In Switzerland Say Zero Emission Society Will Require Seasonal Energy Storage

July 9th, 2019 by Steve Hanley on Clean Technica.com, Researchers In Switzerland Say Zero Emission Society Will Require Seasonal Energy Storage Researchers Martin Rüdisüli, Sinan Teske, and Urs Elber of the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have studied what will be needed to make Switzerland able to use only zero carbon energy. Among their main conclusions is that the …

Should Electrification Strategy Emphasize Heating Over EVs?

The U.K. government is backing electric vehicles more vigorously than hybrid heat pumps. Is that the wrong approach? By JASON DEIGN JULY 05, 2019, GreenTechMedia 14 Hybrid heat pumps (HHPs) can use gas as well as electricity The focus of much attention… Moves to foster electric-vehicle adoption for energy system decarbonization in the U.K. could risk shifting the emphasis away from …

How will decisions change with increased variable, renewable energy (VRE)?

VRE will make it more important to electrify everything, even if, in some contexts (like building heating and cooling), it might mean a short-term reduction in energy efficiency. The more water heaters and electric vehicles are connected to the grid, providing storage and controllable demand, the more stable a high-VRE grid will be. Ancillary services” for the grid include things like …

July 2, 2019 That’s 0.0082677165 inches for Americans, and really thin in either unit. One of the great advantages of Passivhaus design is that they don’t require much heating, in even the coldest of climates. When you don’t need a lot of heat, you get some really interesting options, like this Carbontec heating film, seen at the North American Passive House …
