The Little Technology That Could

Solberg calculates that 75 percent of energy use and costs for heating could be eliminated in commercial, health care and residential buildings through AHR, even in the frosty Midwest.  He points to a new health club in Edina, Minnesota, which is already saving on construction costs and projected to see 50 percent lower operating costs.

Something New to Preserve the Old in Charleston, SC

In a city like Charleston, with deep cultural roots and more historic buildings than you can count, the effects of development on neighborhood preservation and the growing impacts of climate change demand a new approach that can address both issues simultaneously.

CO2 Emissions in Developed Economies Fall Due to Decreasing Fossil Fuel and Energy Use

The research team analysed the reasons behind changes in CO2 emissions in countries where emissions declined significantly between 2005 and 2015. The findings, published in Nature Climate Change, show that the fall in CO2 emissions was mainly due to renewable energy replacing fossil fuels and to decreasing energy use.

Is Transition Worth It?

Are investments in energy transition, especially for public dollars in the form of incentives or subsidies, worth it? Do investments in energy efficiency truly pay off, or does efficiency just make energy cheaper because we’re using less of it, encouraging customers to use more of it—a phenomenon known as the rebound effect, the backfire hypothesis, and the Jevons Paradox?

Digitalization, Efficiency and the Rebound Effect

Debates about the so-called rebound effect go back to William Stanley Jevons’ work in the 19th century, although they had been forgotten for too long. Rebound effects occur if a reduction of inputs per unit of output (efficiency) generates an absolute increase in output (growth).
