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 …

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 …

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 …

Nebraska tribe’s latest energy project: reclaimed solar thermal heaters

In addition to this Nebraska example, solar thermal heating technology is alive and well in Minnesota, where the Rural Renewable Energy Alliance (RREAL) designed its own heater and for years manufactured and installed them at no cost to low-income households. RREAL has shifted its focus to community solar and licensed the design to the White Earth Nation in northwest Minnesota. The tribe …
