A new reconfigurable device that emits patterns of thermal infrared light in a fully controllable manner could one day make it possible to collect waste heat at infrared wavelengths and turn it into usable energy.

In order to have a good chance of meeting the limits set by the Paris Agreement, it will be necessary to both reduce greenhouse gas emissions while preserving carbon sinks,  with net emissions peaking in the next ten years, according to a new study.

Americans used more clean energy in 2016
April 11, 2017 10:13 AM - DOE / Lawrence Livermore National Laboratory

Americans used more renewable energy in 2016 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory. Overall, energy consumption was nearly flat.

Each year, the Laboratory releases energy flow charts that illustrate the nation's consumption and use of energy. Americans used 0.1 quads (quadrillion BTU), more in 2016 than in 2015. A BTU, or British Thermal Unit, is a unit of measurement for energy; 3,400 BTUs is equivalent to about 1 kilowatt-hour.

Project Hotspot
April 7, 2017 03:36 PM - Geological Society of America

In their study published in Lithosphere this week, James Kessler and colleagues examine the geology of a scientific borehole drilled into the Snake River Plain, Idaho, USA, to investigate the potential for geothermal energy at depth. The site discussed in this paper is on the Mountain Home Air Force Base, where a drillhole in 1984 indicated that geothermal fluids were present at about 1.8 km depth.

Record New Renewable Power Capacity Added at Lower Cost
April 7, 2017 11:50 AM - UN Environment

As the cost of clean technology continues to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23 per cent lower than the previous year, according to new research published today by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance.

Global Trends in Renewable Energy Investment 2017 finds that wind, solar, biomass and waste-to-energy, geothermal, small hydro and marine sources added 138.5 gigawatts to global power capacity in 2016, up 8 per cent from the 127.5 gigawatts added the year before. The added generating capacity roughly equals that of the world's 16 largest existing power producing facilities combined.

The Vanishing Nile: A Great River Faces a Multitude of Threats
April 6, 2017 08:49 AM - Yale Environment 360

The Nile River is under assault on two fronts – a massive dam under construction upstream in Ethiopia and rising sea levels leading to saltwater intrusion downstream. These dual threats now jeopardize the future of a river that is the lifeblood for millions.
