New study finds that being a couch potato is green

Years ago, before there was Amazon Prime, TreeHugger concluded that online shopping used less energy than driving to the mall. Now a new study, Changes in Time Use and Their Effect on Energy Consumption in the United States, concludes that many of the technological changes of the last 15 years, from online shopping to Netflix, are contributing to Americans using less energy than they used to. This research tracks lifestyle changes in the United States through changes in times spent on different activities and measures the associated energy effects. We find that Americans are spending more time at home and...

Electric Grid Expert Lays Out Why It’s Basically Impossible Use 100% Green Energy

Powering the grid with 100 percent green energy may sound like a nice idea, but it would actually be extremely difficult to do, a electric grid expert told Greentech Media in an interview Wednesday. “Let’s say we have a 100% system, hypothetically,” Christopher Clack, a National Oceanic and Atmospheric Administration (NOAA) mathematician, said in the interview. “Now you have got think about working out forecasting of load and of the weather, because that’s your fuel source now, seasons or years ahead of time with really good accuracy so that you know how much energy to store, how much to shed,...

Researchers Have Projected When Green Tech Will Surpass Fossil Fuels

Electric vehicles could be cost-competitive with internal combustion-powered cars within five years and batteries that store power from solar panels could become commonplace by 2030 if current investments in those technologies continue, British researchers estimate. A new tool produced by Imperial College London uses data on the prices and installed capacity of battery storage to project how quickly their prices would reach levels that would compete with other energy sources. The findings, published today in the journal Nature Energy, suggest electric cars will match gasoline engines’ costs per mile sometime between 2022 and 2034 — and a solar-battery combination could...
