Learning from Dogs

Dogs are integrous animals. We have much to learn from them.

Turning corners, en route to Plan B.

with one comment

Nothing stays the same for very long!

I wanted to call this post Change out of hope but that title was used on March 17th so opted for Turning corners instead!

Either way, this Post is prompted by a recent item published on the Earth Policy Institute website.  While Lester Brown’s book World on the Edge is a tough read, Lester is President of the Earth Policy Institute, it’s all too easy to think that the future for humanity is wall-to-wall gloom.  So here’s the article that was recently published, reproduced here under the copyright terms of the Earth Policy Institute.

Hope turning on the wind!

Wind Tops 10 Percent Share of Electricity in Five U.S. States

by J. Matthew Roney

A new picture is emerging in the U.S. power sector. In 2007, electricity generation from coal peaked, dropping by close to 4 percent annually between 2007 and 2011. Over the same time period, nuclear generation fell slightly, while natural gas-fired electricity grew by some 3 percent annually and hydropower by 7 percent. Meanwhile, wind-generated electricity grew by a whopping 36 percent each year. Multiple factors underlie this nascent shift in U.S. electricity production, including the global recession, increasing energy efficiency, and more economically recoverable domestic natural gas. But ultimately it is the increasing attractiveness of wind as an energy source that will drive it into prominence.

Wind power accounted for just 2.9 percent of total electricity generation in the United States in 2011. In five U.S. states, however, 10 percent or more of electricity generation came from wind. South Dakota leads the states, with wind power making up 22 percent of its electricity generation in 2011, up from 14 percent in 2010. In 2011, Iowa generated 19 percent of its electricity with wind energy. And in North Dakota, wind’s share was 15 percent.

The two most populous U.S. states are also harnessing more of their wind resources. While adding more than 900 megawatts of new wind farms in 2011 to its existing 3,000-megawatt wind capacity, California was able to increase its wind electricity share from 3 to 4 percent. Texas has the most wind installations of all the states, with 10,400 megawatts. In fact, if Texas were a country, it would rank sixth in the world for total wind capacity. Figures from the Electric Reliability Council of Texas (ERCOT), the independent service operator that delivers 85 percent of the state’s electricity, show that wind’s share of electricity in the ERCOT region jumped from 2.9 percent in 2007 to 8.5 percent in 2011.

Even though the cost of generating electricity from the wind has fallen substantially, certain policies have been needed to help it compete with the longtime support and lack of full-cost accounting for fossil fuels. Through so-called renewable portfolio standards (RPS), 29 states now require a percentage of utilities’ electricity to come from renewables by a certain date. This includes 8 of the top 10 states in total installed wind power capacity. For example, California’s RPS requires one third of the state’s electricity to come from renewable sources by 2020. But the biggest policy driver of U.S. wind power growth thus far has been the federal production tax credit (PTC) for each kilowatt-hour of electricity a wind turbine generates. When Congress has allowed the PTC to expire, as it is scheduled to do again at the end of 2012, wind installations in the following year have plummeted.

In the short term, extending the PTC will be critical for the U.S. wind industry, which boasts more than 400 turbine component manufacturers and employs some 75,000 people. Ultimately, moving away from the recurring boom-bust threat by establishing a national RPS or a carbon tax would encourage even greater manufacturing growth and wind installations.

In a country where wind resources could power the entire economy, there is still great potential to be realized. Four states in northern Germany have set the mark, with each getting more than 40 percent of their electricity from the wind. Which U.S. state will get there first?

This video is well worth watching as well as going to that link at the end of the essay above.

Lester Brown, Thomas Friedman, and Paul Krugman discuss the need for a carbon tax in order to price carbon emissions at their true cost.

The “Journey to Planet Earth” series continues with a special program, hosted by Matt Damon, which features environmental visionary Lester Brown and author of “Plan B.” This documentary delivers a clear and unflinching message — either confront the realities of climate change or suffer the consequences of lost civilizations and failed political states.

I will see how much material there is available online with regard to that programme hosted by Matt Damon and, maybe, present some of it on Learning from Dogs.

Finally, the picture of the wind turbine at the head of this Post came from a website called www.windgeneratorblog.com.  Fancy a home wind generator?

  1. I would be all for wind, if, and I am pretty much for wind, in spite of:
    1) bird killing
    2) insect gluing
    3) loss of wind when greenhouse blossoms
    4) crazy destruction of natural beauty

    The most performing turbines stand 200 meter tall. The latest, in France, made by the TGV manufacturer, Alstom, use magnetic transmission of power (good; no gears!) and have blades 74 meters long…

    OK maybe killing natural beauty in deserted plains does not count, but killing wildlife sure does…

    Also wind, massive, will necessitate hydro, massive (so artificial lagoons, offshore). For storage. Otherwise, it’s going to be like Denmark: #1 wind, #1 coal (for base).
