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 …

The Case for Switching From Natural Gas Hookups to Heat Pumps

7/19 GTM: Geothermal heat pumps are a no-brainer given their efficiency and environmental advantages, argue investor Jigar Shah and Kathy Hannun of Dandelion Energy. The Natural Resources Defense Council claims that installing heat pumps instead of natural-gas lines would save homeowners $1,500 right away, and hundreds of more dollars each year after that in operating costs. Homeowners would also enjoy the benefit …

California cities begin banning natural gas hook-ups in new buildings, in a historic move

 By Susie Cagle in Oakland, for The Guardian, 23 Jul 2019 More than 50 cities and counties in California are now considering similar policies to Berkeley’s, either banning or limiting gas and incentivizing full electrification in new buildings. This week Berkeley, California became the first city in the United States to ban natural, fossil gas hook-ups in new buildings. The landmark …

LED light bulbs, heat-pumps, and electric cars all have something in common each represent an efficiency improvement of 300% or greater over their predecessors. Drastically improving land and food efficiency is also needed.

Drastically improving the efficiency of how much land is used to produce our protein and calories by switching to plant-based or more land-efficient animal sources, will also make it much easier to sustainably produce enough food to feed the world’s growing population. Excerpt from Clean Technica, Carbon Farming Can Deliver, July 2019 LED light bulbs, heat-pumps, and electric cars all …

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 …

Denver Initiative Would Raise Over $40 Million for Housing Efficiency, Retrofits, Training and Support of EJ and Low Income Communities

We have submitted our ballot language with suggested improvements to the City Council Referred Initiative drafters. We would also appreciate all of your input on where you feel changes/improvements should be made.  Please provide changes on the document as comments only or send suggestions to me that I will include in the document.  Thank you all for your help! Here are several equity …

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 …

Getting the Facts Right: Clean, Electric Buildings Can Reduce Greenhouse Gas Emissions AND Save Money in New Construction

Building decarbonization is a necessary component of our overall climate change strategy. Multiple analyses have shown that for new construction it is cheaper to build all-electric than to install gas-fired appliances and air conditioning. RMI found this to be true for all new construction scenarios, even without considering the gas infrastructure costs of new service lines. In all but the most coal-heavy …

40% of U.S. homes were built before 1970 and reducing emissions in the building sector is 40% more cost-effective than investing elsewhere

By Mirella Vitale, SVP of Group Marketing, Communications & Public Affairs at ROCKWOOL GroupMarch 18, 2019 ROCKWOOL: Energy efficiency is the best way to create resilient cities and communities. We’re at an inflection point in the battle against climate change. With each passing day, the time available to address climate change dwindles while the effects of global climate disruption become …
