The Columbia River Basin Provides More than 40% of Total U.S. Hydroelectric Generation

July 7, 2014 by U.S. EIA: Today in Energy

Columbia River Basin Hydro Power

Hydroelectric power plants located in the Columbia River Basin account for a little more than one third of all the hydroelectric capacity in the United States. The Columbia River runs from the Canadian Rockies and flows 1,214 miles through Idaho, Oregon, and Washington.[read more]

Non-Hydro Renewables Generate More Electricity Than Conventional Hydro for First Time

May 30, 2014 by Tom Schueneman

Renewables Growth and Change

Historically large-hydro renewable sources like large dams have contributed most electrical generation from the combined renewable sources including wind, solar, biomass and geothermal. But the tide may be turning on the growing renewable energy mix.[read more]

The Cost of Wind Energy, Part I

May 13, 2013 by Charles Barton

I wanted to find a means of estimating the cost of a one million mega watt (Mgw) wind generator and compare that to the cost of one million Mgw of nuclear generation capacity.[read more]

Demand Response Cuts Need for New Generation in PJM Grid

May 8, 2013 by Adam James

PJM's demand reponse

Increasing reliance on smart technology to revolutionize the way efficiency is utilized represents a departure from the supply-side approach that has traditionally governed the "dumb," centralized electricity system of years past.[read more]

Solar Energy to Account for Most New Generation in California

May 1, 2013 by Herman Trabish

California's grid

Almost all of the new generation capacity in the California transmission system operator’s queue for the second half of 2013 is solar -- 97 percent, to be exact. There are 1,633 megawatts of new generation capacity in the 2H 2013 queue.[read more]

Wind vs. Nuclear Energy in the UK: A Question of Scale

March 21, 2013 by Robert Wilson

nuclear energy in the UK

The UK government has just given planning approval for the first new nuclear power plant in almost 20 years, and someone wanted to know how many windfarms would be needed to generate the same amount of power?[read more]

California’s photovoltaic push

July 9, 2010 by Todd Woody

photo: PG&E I wrote this post for Grist, where it first appeared. Amid the hullabaloo over government-chartered mortgage giants derailing the green financing program known as Property Assessed Clean Energy, or PACE, the march toward distributed generation of renewable energy – that is, generating electricity from...[read more]

A smart electric network – in more ways than one

June 29, 2010 by Rich Maltzman

As we often do here on EarthPM, we are going to combine a couple of pertinent and important themes to hopefully strengthen some points that are key to each of them. The two themes we relate here are: Electric Smart Grids for effective power transmission and reduced carbon footprint High-powered Grids of Smart PMs to gain a bigger...[read more]

Mixed outlook for gas reactors

June 9, 2010 by Dan Yurman

Progress planned in Europe, but a fire sale looms in South Africa The future of high temperature gas-cooled reactors is taking different directions depending on where you look. In Europe a multi-national collaboration is working on plans for a site to build the Allegro Reactor. However, in South Africa the proposed “rescue plan” for the...[read more]
