More Clean than Dirty Power Installed in 2007

For all we talk about solar and beta blockers and levitra wind power, they still produce tiny amounts of the United States' (and the World's) electricity. But now we've finally got some numbers reflecting just how exciting renewables are. In 2007, the U.S. the majority of new power installed was wind power, and total production of coal-fired power actually shrunk!

A total of 8.6 gigawatts of new power were installed in 2007 with around 5 gigawatts of that coming from wind. Almost all of the rest of the power addition came from natural gas.

Two coal fired power plants went online in 2007 for a total addition of just over a gigawatt. However, reductions and retirements of coal fired power elsewhere actually resulted in a 200 MW decrease in coal-generated power during the year.

That's freaking awesome.

Sometimes it's hard to see long term when we're all focused so much on the day's big breakthrough. But it's important to note that 2007 was a breakthrough year even though no one noticed. We can't just shut down all the coal-fired power plants in America, but we can start installing clean power instead of dirty power.

The Department of Energy apparently takes a long time to where to buy viagra pills get these reports together, they just released these 2007 numbers about a week ago. But, frankly, I'm already holding my breath for 2008's numbers. You can read the full report here.

This is a great trend to see taking shape as wind and solar become the levitra alternative predominant methods of new power generation. Continued installations will then allow for further reductions in the need for coal, which will have a very beneficial effect on lowering CO2 emissions.

Wind and solar are great as they provide long term jobs and almost no pollution (ex the creation of the hardware). Coal jobs rely on dangerous work to both the miners and to the public.

Thanks Hank for the encouraging news.

I agree with all the comments here, a great trend that will continue and grow in the upcoming months, years. This is really encouraging, especially in this crazy economy. Green power and cialis to order green jobs will play a significant role in helping the United States on so many different levels.
Efficiency Savings?
written by Norbert, February 03, 2009
This is good news. Estimating how much energy supply growth was avoided through efficiency improvements would also be worth knowing. The ACEEE report estimated that 3/4 of the demand since 1970 was satisfied through efficiency, and only 1/4 through supply. Although we definitely need to ramp up renewables, a good way to get ahead of the curve is best levitra using less electricity.

Great news indeed but the overhyped wind and solar will never replace coal and other fossil fuels without adequate storage. They are intermittent energy.

There is no shortage of baseload green energy.

Geothermal is the most potent green energy of all. It is both superior to and cheaper than fossil fuels by some estimates.

Biomass is replacing coal today over vociferous opposition by some that pretend they are environmentalists.

Best, Terry
Coal really reducing?

In the report mentioned as a source of your article, it reads: "In 2007, electricity generation from coal-fired capacity increased 1.3 percent, reversing the decline from 2005 to 2006. Coal-fired generation increased from 1,991 million MWh in 2006 to 2,016 million MWh in 2007. This is a new record, exceeding the previous all-time high of 2,013 million MWh set in 2005. The record level of coal-fired generation reflects a one percentage point increase in the average capacity factor of cheapest levitra in uk coal-fired generation to 73.6 percent."

Regarding the energy mix, it reads "In spite of setting a record level for generation in 2007, coal’s share of total net generation continued its downward trend in 2007. It accounted for 48.5 percent of total net generation in 2007 as compared to 49.0 percent in 2006 and 52.8 percent in 1997. Nevertheless, it remains the primary source of baseload generation. The decline in coal’s share of total net generation in 2007 was attributable to continued increase in the share of total net generation produced by natural gas-fired and nuclear capacity, as well as renewable sources, other than conventional hydroelectric capacity."

It seems that coal is only being replaced by other I reading this right? I would love to see renewables taking a bigger chunk out of the coal portion.

Also "Estimated carbon dioxide emissions by U.S. electric generators and combined heat and power facilities increased by 2.3 percent from 2006 to 2007 (from 2,460 million metric tons to 2,517 million metric tons). This reverses the decline in carbon dioxide emissions reported for 2006."

I would like to be optimistic about 2007, but the report doesn't provide this for me.
