TVA Pulls the Plug on More Coal Plants; Others Will Surely Follow

Last week, the Tennessee Valley Authority’s (TVA) board of directors voted in favor of retiring 3,300 megawatts (MW) of coal power capacity. This action is good news for consumers and the environment in the region. It also continues the drumbeat of retirement announcements nationwide and provides further evidence of the eroding economic viability of the aging U.S. coal fleet. A recent UCS analysis, Ripe for Retirement, documents why many more U.S. coal generators should also be considered for closure. Read More

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

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

Electricity Rate Hikes in California? Not the Jolt Clean Energy Opponents Claim.

A coalition of industry trade groups that have long opposed California’s clean energy policies funded a report about a month ago that blamed California’s rising electricity rates on — you guessed it — California’s clean energy policies. Since the California Energy Commission just updated its electricity and natural gas demand forecast, which contains revised estimates for rate increases that are 15-20 percent lower than original predictions (see slide 3 of Tuesday’s presentation), I thought it was time for a blog on the subject of renewables and rates.

Renewable Energy Contracts and Energy Efficiency Progress: New England is Sprinting

For fans of the Boston Red Sox and the New England Patriots, life in New England right now is awfully good. The Sox hold a commanding lead in the race to the post-season, and the Patriots are 3-0.*

Life in New England is also good for fans of clean energy and a stronger, cleaner energy future, which should include just about anyone with lungs or a wallet. Just-announced plans for more local renewable energy, and a new report on best cities for energy efficiency, show the important progress New England is making in some key areas for our economy and our environment.

Latest Data on Solar Shows Price Declines through 2012

According to the latest Tracking the Sun report from the Department of Energy’s Lawrence Berkeley National Laboratory (LBNL), prices for installed solar photovoltaic (PV) systems fell between 6% and 14% in 2012. The report also contains a 2013 snapshot for California systems, where prices fell by an additional 10% to 15% in the first 6 months. 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

In Chicago, ALEC Reboots Failed Strategy for Attacking Renewable Energy Policies

Having failed completely in its attempt to repeal state renewable electricity standards (RES) during the spring 2013 legislative season, the American Legislative Exchange Council (ALEC) is shifting gears. Their new strategy is more nuanced, but the goal remains the same: support their fossil fuel cronies by rolling back renewable energy policies. Fortunately, this latest scheme is likely doomed to fail as well. Read More

Arizona: Don’t Turn Out the Lights on Solar Power

Arizona, a state known for abundant sunshine and one of the fastest growing populations in the country, may be changing its rooftop solar program in a way that would decrease the benefits that utility customers receive from installing solar panels on their roofs. Read More
