Energy and Environment Monitor: Summary of EPRI Prism/MERGE 2009 Analyses Report: EPRI ... - 0 views

  • In 2007, the Electric Power Research Institute (EPRI) released its first “Prism” model and Model for Estimating the Regional and Global Effects of Greenhouse Gas Reductions (MERGE). 
  • EPRI updated both analyses in 2009 to reflect economic and technological changes that have the potential to affect projected emissions and the technologies to address them. 
  • The Prism analysis projects that by 2030, 60% of the total U.S. generation mix would consist of low- or non-CO2 emitting generation

Green Car Congress: EPRI-NRDC Studies Highlight GHG and Air Quality Benefits of Plug-in... - 0 views

  • Widespread adoption of PHEVs could reduce GHG emissions from vehicles by more than 450 million metric tons annually in 2050—equivalent to removing 82.5 million passenger cars from the road. Cumulative GHG emissions reductions from 2010 to 2050 could reach 10.3 billion metric tons under the most aggressive scenarios for the development of a lower-carbon electrical infrastructure and PHEV penetration.

Distributed Renewables Can Defer Infrastructure Investments | The New Rules Project - 0 views

  •  
    This recent article by the Manager of EPRI published on EnergyCentral.com discusses how conventional photovoltaic (PV) applications can act as distributed resources when the sun is shining -- rather than solely as a reduction in load

Pumped Hydro: Is it TOO Green? | PeteSinger - 1 views

  • In the latest Electric Power Research Institute Journal, an article titled "Hydropower Reservoirs: A Question of Emissions" notes that reservoirs used for hydropower and for pumped-hydro energy storage are not necessarily as green as you might imagine. Or rather, they might be too green: carbon-rich organic material that accumulates on the reservoir floor can be the source of carbon emissions. A recent study of the 90-year-old Lake Wohlen, in Switzerland, for example, found high emissions of methane, as recently reported in the journal Environmental Science and Technology, in an article titled: "Extreme Methane Emissions from a Swiss Hydropower Reservoir: Contribution from Bubbling Sediments."
  •  
    Applies to both hydro reservoirs (i.e. water pooled behind a dam) and hydro pools filled with pumped-hydro. Note that the latter, pumped-hydro, already carries the emissions profile of the energy used to power the turbine pumping the water against gravity, scaled up for conversion efficiency losses.
