We’re headed to Paris. But where did we come from?

by Ensia  (May 20, 2015)

A look at past UN climate negotiations offers valuable context for this year’s pivotal talks. 2015 is shaping up to be a pivotal year with respect to climate change as growing concern about impacts converges with a critical stage in the decades-long process of shaping an international agreement to change our trajectory. To help us all ...

Clean-Energy Innovation Essential to meeting Climate Goals – IEA Report

by GLOBE Foundation  (May 4, 2015)

A concerted push for clean-energy innovation is the only way the world can meet its climate goals, the International Energy Agency says as it released its flagship energy technology report. The report, Energy Technology Perspectives 2015 (ETP 2015), shows that despite a few recent success stories, clean-energy progress is falling well short ...

US plant shutdowns, grid focus drive storage growth: Greensmith CEO

by Wind Energy Update - part of the FC Business Intelligence Ltd group  (May 4, 2015)

Power plant closures and hiking transmission costs are driving up US utilities’ investment in renewable energy storage, John Jung, CEO of Greensmith, an energy storage services firm, told Wind Energy Update. Some 60 GW of US coal-fired capacity is set to close between 2012 and 2020, according to the EIA. Nuclear plant lifespans will end and ...

Greenhouse Gases-California-Things to Know

by Associated Press  (Apr. 29, 2015)

Here are some things to know about California Gov. Jerry Brown's new target for reducing carbon emissions that contribute to climate change. WHAT DO THE NUMBERS MEAN? Brown set a goal for the state to reduce emissions to 40 percent below what they were in 1990. Countries set that year as a benchmark for climate change when they signed on to the ...

Determinants of corporate carbon reduction targets

by Inderscience Publishers  (Sep. 25, 2014)

This paper examines attributes affecting a corporation’s choice of an intensity-only (carbon emissions relative to sales, production, etc.) versus an absolute carbon dioxide (CO 2 ) emissions goal. We investigate alternative hypotheses for this choice including: 1) a high growth hypothesis whereby high growth companies select an intensity goal, ...

City of Houston Total Organic Carbon - Case Study

by TOC Systems, Inc.  (Mar. 2, 2015)

ABSTRACT The City of Houston, Texas has been aware of the implications that current and pending regulatory standards would have on the operation of their four surface water treatment facilities. In particular, the City has closely monitored changes in regulations related to enhanced coagulation, total organic carbon (TOC) removal, and ...

Hexavalent chromium reduction and energy recovery by using dual-chambered microbial fuel cell

by IWA Publishing  (Feb. 26, 2015)

Microbial fuel cell (MFC) technology is utilized to treat hexavalent chromium (Cr(VI)) from wastewater and to generate electricity simultaneously. The Cr(VI) is bioelectrochemically reduced to non-toxic Cr(III) form in the presence of an organic electron donor in a dual-chambered MFC. The Cr(VI) as catholyte and artificial wastewater inoculated ...

Removal of bromide and bromate from drinking water using granular activated carbon

by IWA Publishing  (Feb. 27, 2015)

Granular activated carbon (GAC) was used to remove bromide (Br−) and bromate (BrO3−) from drinking water in both bench- and pilot-scale experiments. The present study aims to minimize BrO3− formation and eliminate BrO3− generated during the ozonation of drinking water, particularly in packaged drinking ...

Influence of COD/sulfate ratios on the integrated reactor system for simultaneous removal of carbon, sulfur and nitrogen

by IWA Publishing  (Mar. 16, 2015)

An integrated reactor system was developed for the simultaneous removal of carbon, sulfur and nitrogen from sulfate-laden wastewater and for elemental sulfur (S0) reclamation. The system mainly consisted of an expanded granular sludge bed (EGSB) for sulfate reduction and organic carbon removal (SR-CR), an EGSB for denitrifying sulfide removal ...

The jobs impact of GHG reduction strategies in the USA

by Inderscience Publishers  (Dec. 2, 2014)

This paper estimates the economic and jobs impact of the USA displacing 1.2 billion tons of carbon emissions annually by 2030 using energy efficiency and renewable energy. We assess the technologies deployed, their costs, and the necessary time frames. We then estimate the job impacts of the policy and find that it will generate more than 4.5 ...
