The service began with 370 cars, including electric BMW i3 sedans and conventional 3 Series and MINI offerings. A year later, the ReachNow fleet has grown to more than …

Unsubsidized offshore wind power just won a German power auction – offshore wind is steady, stronger, and close to population centers

BNEF: As natural gas and coal plants are increasingly idled in favor of renewables, their capacity factors will take a big hit, and lifetime cost of those plants goes up. Think of them as the expensive back-up power for cheap renewables. Offshore wind won a German power auction without needing any subsidies: As prices plummet, offshore wind is now competitive with …

Vehicle-To-Grid discharge, even at constant power, is detrimental to EV battery performance, study finds

By James Ayre, Clean Technica, May 16th, 2017 There have long been critics of the idea of widespread use of electric vehicle (EV) vehicle-to-grid (V2G) technologies for a variety of reasons, but largely in relation to the potential damage done to EV batteries, and thus reduced battery lifespan.  New research from the Hawaii Natural Energy Institute at the University of Hawaii at …

Allergy, oak pollen and ragweed seasons growing with climate change

More children could wind up in hospital emergency rooms suffering from allergy-induced asthma if greenhouse gas emissions continue to rise and cause longer oak pollen seasons, according to a new study. The new research finds that if greenhouse gas emissions continue to increase through the end of this century, the oak pollen season in some areas could extend by up …

Declining precipitation in Colorado River Basin worsened by rising temperatures

Scientists found that another factor affected the runoff ratio: temperature. Over the last few centuries, the runoff ratio was reduced when temperatures were warmer. And the influence of temperature strengthened during drier years: When the snowpack was shallow, warm temperatures reduced the runoff ratio more than when the snowpack was deep, further exacerbating drought conditions. The low runoff ratios seen …

Low hedges along roads instead of taller trees, help air pollution and health

Science Daily, 16 May 2017 The harmful impact of urban air pollution could be combated by strategically placing low hedges along roads in a built-up environment of cities instead of taller trees, a new study has found. The study, just published in the journal Atmospheric Environment, points out that low hedges reduce the impact of pollution from vehicles in cityscapes …
