Electric Generator Capacity Factors Vary Widely Across the World

September 8, 2015 by U.S. EIA: Today in Energy

Electric Generation Variance

The tech used to generate electricity are similar across regions of the world, but the pattern of use for those generating technologies can be significantly different. Analysis of electric generating plant utilization over a five-year period shows a wide range of variability among fuel types and across world regions.[read more]

Opportunity and Crisis in South Africa's Electricity

June 4, 2015 by Sussex Energy Group

South Africa is in an electricity crisis. It has resulted in regular load-shedding across the country since late last year as the country’s cash strapped utility Eskom faces a $17 billion funding gap to 2018. Electricity consumers face a 250 per cent cumulative increase in electricity prices since 2008.[read more]

And the Winner Is: Distributed Generation

April 11, 2015 by Nigel Morris

Not a day goes by when I don’t learn something new about what solar energy can do and frankly, how many falsehoods exist about “the problems” that it theoretically causes. But what I love most is when facts and data bust the myths being spouted and today, we got an extremely cool new set of truths.[read more]

GE's New Gas Turbines Are State of the Art, But Are We Getting Too Cozy With the Fuel?

April 9, 2015 by Jared Anderson

GE, Turbines, and Fuel

The first natural gas-fired turbine for US power generation and one of today’s state-of-the-art designs currently live on GE’s massive 413-acre Greenville, South Carolina campus. The fact that both machines convert natural gas into electricity is pretty much where the similarities end.[read more]

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]
