Ripe for Retirement: Examining the Competitiveness of U.S. Coal Plants

This is Part One of a 3-Part Blog Series.

Today, the Union of Concerned Scientists released an update of our 2012 ground-breaking analysis, Ripe for Retirement, examining the economic viability of U.S. coal generators compared with modern, cleaner alternatives. Our new findings, published in Electricity Journal, show that nearly 59 gigawatts (GW) of coal power capacity are not cost competitive when compared with natural gas, and more than 71 GW are uneconomic when compared with wind power. These coal generators are prime candidates for retirement and their closure would provide substantial benefits for consumers and the environment. It would also accelerate the transition to a cleaner, more reliable and affordable energy system. Read More

Misleading IER Report on Wind Power Ignores Some Crucial Facts

A new, misleading report on wind power has emerged from the Institute for Energy Research. This small single-issue group has released an analysis of a single federal tax policy – the wind energy Production Tax Credit (PTC) – and hidden an awful lot of relevant information in the process, including the group’s history of payments from fossil fuel interests and its distortions of renewable energy facts.

Climate Science, Nuclear Power, and a Renewable Energy Future

Contrary to the public assertions made this week by some of our climate scientist friends, nuclear power is likely to have a limited near-term role in avoiding the worst impacts of climate change. Renewable energy technologies are cheaper, less risky, and ready for deployment today. A look at where things stand with both nuclear and renewables bears all that out. Read More

The Falling Cost of Wind Power Spurs New Investments

After a very slow start in 2013, U.S. wind development is really starting to pick up. According to the American Wind Energy Association’s (AWEA’s) just released Third Quarter 2013 Market Report, over 7,500 megawatts (MW) of new wind power capacity is under development in the U.S., representing an investment in the U.S. economy of roughly $15 billion.

Disproving the Skeptics: 10x More Windpower and Solar is No Problem!

What would happen if we tried to make the electric supply 30% wind and solar? Air pollution goes down, and reliability is unaffected. Ok, now picture adding as much as 50,000 MW of wind and 60,000 MW of solar by the year 2026, and the engineers saying, “Sure, we can do that.”

That’s the finding of a study previewed today by the grid operator PJM and a consulting team led by General Electric. Read More

Do Wind Turbines Affect Property Values? No — or at Least “No Statistical Evidence” — Says New Hedonic Study

I noted in my recent post on wind turbines and tourism that a related issue, wind farms and property values, was also important to consider. A new study does just that, and finds “no statistical evidence” of effects. Read More

Where Is Wind Energy Cheaper than Natural Gas?

Answer: The gas-rich states of Oklahoma, Texas, and Colorado. This week, utility Public Service Co. of Oklahoma announced that it tripled its planned purchase of 200 MW of wind energy, to 600 MW, because of the immediate savings to its customers and the 20-year guaranteed stable pricing. Read More

Water-Smart Power Can Help Declining Aquifers

A new study about declining aquifers in the Great Plains focuses on the agricultural sector’s water use, as it should. But water-smart power choices can help, too, by cutting electric-sector pressure on precious groundwater resources. Read More

“Not A Good Day in the Neighborhood” — Electricity Grid Progress since the August 2003 Blackout

Electricity grid operators knew hours before the 4 p.m., August 14, 2003 Northeast power failure that things were going badly. One called his wife, predicting accurately that he would have to work late, and another complained it was “not a good day in the neighborhood.”

The largest blackout in North America left 50 million people without power and largely without communications, but some engineers knew that the blackout could have been prevented. Part two of a two-part series on the Northeast Blackout of 2003. Read More
