GRAPH: US Energy Supply Source Percentages Hold From 2009-2010, But Overall Usage Continues Growth

Graphs, Charts, Diagrams: This series of posts (tag: Graphs-Charts-Diagrams) will focus on visuals  that help create context for large scale issues, such as energy usage.

Above is a chart by the Energy Information Administration (USA), featured in the Annual Energy Review 2010 (see full chart and other EIA resources here). While I am particularly curious to see what the data will be for 2011, 2012, and 2013 in the light of the natural gas trending, the takeaway from this graph, when compared to the one of the previous year, is that nothing has changed – at least in terms of macro-categories. There is a shift in what renewable sources provided the 8% of national supply, yet the dominance of Petroleum, Natural Gas, and Coal hold steadfast.  Continue reading

EIA: How many/what kind of power plants in USA?

Want some stats? Here you go.

http://www.eia.gov/electricity/annual/pdf/table1.2.pdf states there are over 5K natural gas generators as top source in number of plants as well as nameplate capacity; coal is second in capacity, but conventional hydroelectric is second in generator numbers.

The capacity of fossil fuel plants far outweighs that of renewable plants, at this time…

How many and what kind of power plants are there in the United States?

There are about 18,000 individual generators at about 5,800 operational power plants in the United States with a nameplate generation capacity of at least one MegaWatt. A power plant can have one or more generators, and some generators may use more than one type of fuel.

Minds Meet on Shale Gas, Fracking by Bill Chameides

The Takeaway: We Gotta Get Natural Gas Right

After yesterday’s session, a small group of us retired to the Faculty Commons for a glass of wine, dinner, and conversation. We were treated to a short talk by Richard Newell, a Duke professor and the director of Duke’s Energy Initiative, who returned last fall from a stint in the Obama administration as the head of the Energy Information Administration. Richard provided a fascinating overview of the issue from the perspective of someone who has spent the last two years trying to make sense of the nation’s long-term energy future.

Some relevant history: Hydraulic fracturing is as old as … well if not quite the hills, let’s just say it’s not new. A kind of hydraulic fracturing was first done in the late 19th century using nitroglycerin (see here, here and here [pdf]). Horizontal drilling is also not all that new, dating back to the 1950s. It wasn’t until the 1990s that the two were put together, and the application of the process to extract shale gas didn’t really begin until the middle part of the last decade, but since then, it’s become a game changer — initially responsible for a percent or two of all natural gas production, it’s now producing about 30 percent of U.S. supply.

The economic impact has been huge. For instance, in 2006, the federal government was discussing ways to accelerate the construction of billion-dollar port facilities for processing imported liquified natural gas because it was believed we faced an imminent natural gas shortage that would put our electricity supply at risk. Today we have an overabundance of natural gas, prices are down and few are lining up to invest in such a facility.

Another point Richard made: The global shale gas resource is huge, so large that exploiting it will dominate supply and therefore set natural gas prices at least for the next decade. So from today’s perspective, shale gas is here to stay, a resource that will be exploited. So we’d better get it right.

If fossil fuel infrastructure is not rapidly changed, the world will 'lose for ever' the chance to avoid dangerous climate change

The world is likely to build so many fossil-fuelled power stations, energy-guzzling factories and inefficient buildings in the next five years that it will become impossible to hold global warming to safe levels, and the last chance of combating dangerous climate change will be “lost for ever”, according to the most thorough analysis yet of world energy infrastructure.

The new research adds to that finding, by showing in detail how current choices on building new energy and industrial infrastructure are likely to commit the world to much higher emissions for the next few decades, blowing apart hopes of containing the problem to manageable levels. The IEA’s data is regarded as the gold standard in emissions and energy, and is widely regarded as one of the most conservative in outlook – making the warning all the more stark. The central problem is that most industrial infrastructure currently in existence – the fossil-fuelled power stations, the emissions-spewing factories, the inefficient transport and buildings – is already contributing to the high level of emissions, and will do so for decades. Carbon dioxide, once released, stays in the atmosphere and continues to have a warming effect for about a century, and industrial infrastructure is built to have a useful life of several decades.
