High technology feels so clean—no coal or steam or mess, just cool aluminum, sleek plastics, and polished glass. But that clean surface hides an interior that is far messier and more toxic…researchers took apart 36 phones and submitted their components to X-ray fluorescence spectrometry…then rated and ranked the phones on a scale of 0 – 5, lowest being best:
24 out of 25 oldest plants (60+ years) are hydropower
Nearly all nuclear plants are 20+ years old
Here is a graphic from EIA with more detail. The pie chart shows how much generating capacity comes from each fuel type. The graph shows capacity by year the plant was built.
Notice that hydropower was the first energy source built, the creation of coal plants dominated from 1950 to the mid-80s, and it’s been all natural gas since then.
But, age may not matter when it comes to operating power plants, from Wiki Answers:
In a nutshell, it is not correct to assign human attributes (e.g., lifetimes) to inanimate objects. Consequently, the operating span of a coal fired power plant can be unlimited since any degraded or failed component can be replaced with a new one. The decision on whether to make a refurbishment, or to build a new plant, is merely a question of relative economics and investment risk. For example, the cost of a single replacement part is almost always less than the cost of replacing the plant. However, in an old plant, there is a risk that many additionally worn parts also will need replacement soon. Plant owners evaluate these tradeoffs each time a major component fails and make the decision whether or not to retire the plant.
In a surprising turnaround, the amount of carbon dioxide being released into the atmosphere in the U.S. has fallen dramatically to its lowest level in 20 years, and government officials say the biggest reason is that cheap and plentiful natural gas has led many power plant operators to switch from dirtier-burning coal.
Isn’t that great news?
I think we need some uplifting climate change news with all the “doom and gloom” stories out there. Let’s keep it going.
The United States has cut its CO2 output more than any other country in recent years, with our output dropping since 2007. We are now close to 1990 levels and may be able to fit in with the Kyoto Protocols.
Of the fossil fuels, natural gas releases the least amount of air pollution and CO2. It is a homegrown source which improves our energy independence and stability, as well as keeping our money at home.
Coal has gone from producing half our energy to only one-third.
** Fracking for natural gas – it is unknown how destructive this new, hugely popular process is.
Fishermen were casting their lines into the urban waters of Washington, D.C., into a river notorious as one of the dirtiest in the nation. What’s more, according to a recent study, they represented a small fraction of the 17,000 or more residents of this metropolitan area who are consuming fish from a river that has all the markings of a Superfund site.
Sometimes you just can’t believe it, the article even says that a sewer line directly dumps a billion gallons of human waste every year.
A refreshing, well-balanced look at climate change in America.
You don’t have to be a climate scientist these days to know that the climate has problems. You just have to step outside.
The United States is now enduring its warmest year on record…Meanwhile, the country often seems to be moving further away from doing something about climate change, with the issue having all but fallen out of the national debate.
Behind the scenes, however, a somewhat different story is starting to emerge — one that offers reason for optimism to anyone worried about the planet. The world’s largest economies may now be in the process of creating a climate-change response that does not depend on the politically painful process of raising the price of dirty energy. The response is not guaranteed to work, given the scale of the problem. But the early successes have been notable.
Over the last several years, the governments of the United States, Europe and China have spent hundreds of billions of dollars on clean-energy research and deployment. And despite some high-profile flops, like ethanol and Solyndra, the investments seem to be succeeding more than they are failing.
At this Central Park adventure, kids will hammer, saw wood, make forts, push themselves around in the shallow water on a raft and do all sorts of climbing, jumping and whatever they choose. Kids can raft on a small pond, navigate a rope bridge, use a cable slide, go down a mud slide and more. Bring a spare change of clothing, a plastic bag to put the wet clothes in and close-toed shoes for safety.
Parents will not be allowed to tell the kids, “Don’t get dirty.” Sorry mom or dad. The dirt is what this is about and you must just butt out!
This summer-fun event is held annually. Adventure Playground runs mid-June through mid-August. This experience is suitable for kids six to twelve years old. It is only open from 10 a.m. to 4 p.m., Monday through Saturday, closed Sunday. Adult supervision is provided and a small fee is charged. For information and group reservations, phone (714) 842-7442.
Location: Huntington Central Park, 7111 Talbert Avenue , Huntington Beach, California.

The current explosion in cloud computing offered by major IT companies is driving significant new demand for dirty energy like coal and nuclear power, according to a new report from Greenpeace International.
The report, “How Clean is Your Cloud?” shows a growing split within the tech industry between companies that are taking steps to power their clouds with clean energy, like Google, Yahoo and Facebook, and companies like Apple, Amazon and Microsoft who lag behind by choosing to build their growing fleets of data centres to be powered by coal and nuclear energy.
“When people around the world share their music or photos on the cloud, they want to know that the cloud is powered by clean, safe energy,” said Gary Cook, Greenpeace International Senior Policy Analyst. “Yet highly innovative and profitable companies like Apple, Amazon, and Microsoft are building data centres powered by coal and acting like their customers won’t know or won’t care.”
The report research found that if the cloud were a country its electricity demand would currently rank 5th in the world, and is expected to triple by 2020.
“While many IT companies have made great strides in efficiency, that’s only half the picture – they need to make sure their energy comes from clean sources,” said Gary Cook, Greenpeace International Senior Policy Analyst.
Companies like Google, Yahoo and Facebook are beginning to lead the sector down a clean energy pathway through innovations in energy efficiency, prioritising renewable energy access when siting their data centres, and demanding better energy options from utilities and government decision-makers.
