Energy Needs of China’s Consumers Swamping Efficiency Gains


Share/Bookmark
Already, in the last three years, China has shut down more than a thousand older coal-fired power plants that used technology of the sort still common in the United States. China has also surpassed the rest of the world as the biggest investor in wind turbines and other clean energy technology. And it has dictated tough new energy standards for lighting and gas mileage for cars.
China's CO2 emissions

Keith Bradsher has filed an important story showing how the  energy demands of China’s emerging consumer class are overwhelming the central government’s efforts to cut industrial energy waste and blunt growth in carbon dioxide emissions.

The article provides a closeup view of the demographic and economic forces that are destined to make Asia the dominant influence on the planetary greenhouse for decades to come, by almost every analysis.

Yes We Can Include Energy


Share/Bookmark
President Obama made it clear in his Inaugural address that energy will play a central role in the “remaking of America”. In his speech, the President cited both energy and the environment as symptoms of the crisis facing America.
The state of the economy calls for action, bold and swift, and we will act — not only to create new jobs, but to lay a new foundation for growth. We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together. We will restore science to its rightful place, and wield technology’s wonders to raise health care’s quality and lower its cost. We will harness the sun and the winds and the soil to fuel our cars and run our factories.
“With old friends and former foes, we will work tirelessly to lessen the nuclear threat, and roll back the specter of a warming planet.” He even nodded to America’s higher per-capita use of energy and natural resources: “[N]or can we consume the world’s resources without regard to effect. For the world has changed, and we must change with it.”

Gazprom Prepares To Leave Ukraine Shivering


Share/Bookmark
The Russian energy company is poised to cut off the gas supply to Kiev as disagreements regarding debt repayment and pricing persist.
Russian Prime Minister Vladimir Putin warned that there would be "serious consequences" for Ukraine if the country were to intercept gas supplies destined for the rest of Europe.


Gazprom Prepares To Leave Ukraine Shivering
Melinda Peer

With negotiations between Russian energy company Gazprom and Ukraine at an impasse just a few hours before the firm's midnight deadline, it looks increasingly likely that Kiev residents will start 2009 without supplies of gas. Gazprom engineers are prepared to make good on a threat to shut down the gas pipelines in the absence of an agreement.

After Gazprom reiterated on Wednesday that failure to resolve the dispute over Kiev's $2.0 billion gas-supply-related debt would result in a cutoff, the company said. Without a new gas supply contract, Gazprom said it "won't have any legal grounds to supply gas beyond the customs territory of the Russian Federation to Ukraine." Shares of Gazprom trading on the pink sheets gained 10 cents, or 0.7%, to $14.40, during New York's afternoon trading session.

"The talks with Ukraine haven't brought any concrete result," said Alexey Miller, chairman of Gazprom's management committee. "We are seeing now during the talks that the gas issue has ceased to be an economic one, but is a political bargaining chip for Ukraine," he added, as concerns spread regarding the availability of gas supplies for European states that get gas from pipelines that transit through Ukraine.

Russian Prime Minister Vladimir Putin warned that there would be "serious consequences" for Ukraine if the country were to intercept gas supplies destined for the rest of Europe. Previously, Ukraine had said Europe's supply would be unaffected by the dispute.

The two sides have been engaged in negotiations regarding Kiev's $2.0 billion debt ahead of Wednesday's deadline but had made little headway as of late Tuesday. (See "Gazprom Feels The Pinch.") According to TradeTheNews.com, by early Wednesday, both sides appeared to be set on resolving the dispute by means of political intervention from Moscow, but little progress was achieved Wednesday, as the players argued over supply pricing for the coming year. Gazprom raised the country's prices by 40.0%, but they are still cheaper than those Western Europe is paying.

Sun, Stone and Stimulus


Share/Bookmark
I just finished reading a good article over in the MarketBeat section of the Wall Street Journal. If you have the time it is worth reading.
A number of strategists have put forth the theory that the beginning of a new presidential administration will spark a bit of a market rally, in part because it has happened in the past, and in part because of expectations for a stimulus package focused on infrastructure.
First Solar, a maker of solar panels and builder of solar power plants, is trading around $136, up 59% from its low in November, cutting its losses for the year to less than 50%. First Solar, a stock-market star in late 2007 and early 2008, is set to have another run in early 2009 because of gathering momentum, technicians say.

“The initial target would be the December 18 high around $149, about 13% from here,” said Ryan Detrick, senior technical strategist at Schaeffer’s Investment Research. “If it clears that first level, I wouldn’t be shocked at all if it goes up to the $180 level, its Nov. 14 high.”

Wind Energy Bumps into Power Grid's Limits


Share/Bookmark
There seems to be a consistent problem with new energy sources getting to the final distribution point. Now with the new solar craze, I have to wonder...what is the solution?

The Energy Challenge

When the builders of the Maple Ridge Wind farm spent $320 million to put nearly 200 wind turbines in upstate New York, the idea was to get paid for producing electricity. But at times, regional electric lines have been so congested that Maple Ridge has been forced to shut down even with a brisk wind blowing.

That is a symptom of a broad national problem. Expansive dreams about renewable energy, like Al Gore’s hope of replacing all fossil fuels in a decade, are bumping up against the reality of a power grid that cannot handle the new demands.

The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.

The Solar House, Part Two and Three


Share/Bookmark
In fact, because we now generate more solar energy than we can use, we welcome friends who own electric vehicles over to charge their car batteries for free.


Solar House Part 2 (Aug)
This month we reinstalled the 4-kW solar array over our main roof and put in place the 2-kW, triangle-shaped array of 14 panels over our garage. Our now 6-kW solar system includes a 4-kW inverter to convert the DC electricity coming from the solar panels into AC to power our appliances. Most homes wouldn't require a 6-kW system; we added the extra 2-kW solely to power up the 24 nickel metal hydride batteries in our Toyota RAV4 all-electric vehicle (seen in main image). In fact, because we now generate more solar energy than we can use, we welcome friends who own electric vehicles over to charge their car batteries for free. Cost: included in costs noted in "Solar, Part 1"

Battery Backup (Sep)
To be prepared in case of blackouts, we installed an 8-kW battery reserve system. This includes an inverter and charge controller that regulate energy flow to and from the batteries. If the utility grid goes down and we have a string of very overcast days, our batteries will give us about three days worth of conservative electric use. If the sun is shining, we have unlimited energy, of course. Cost: included in costs noted in "Solar, Part 1"

Solar, Part 3 (Oct)

This month we replaced our natural gas-fired water heater with an active, closed-loop solar hot water system (see the two gray solar panels visible on the left side of the roof) and a new 220-volt electric hot-water heater. Cost: $2,500

New Heating/Cooling (Jan)

The final step in making our house comfortable involved replacing the old, five-ton heating, ventilation, and air conditioning (HVAC) system with a split-ductless heat pump/HVAC system. This is a three-zone system, with small units in the den, dining room, and upstairs master bedroom. The system has an outside central operating unit and a compressor-heat exchanger that is about half the size of a typical air conditioner. Cost: $4,200

Costs & Benefits

After $18,500 in rebates and tax incentives, the total cost for all our energy-efficient improvements and our solar system, including labor, came to $43,000. We calculated that, if we had not made the retrofit, our energy bills for 2004, including fuel and oil for a gas-powered car, would have come to $6,000. With the upgrades, we have no energy costs (except for $5 a month for the one therm of natural gas we use, mostly for cooking). Thus, our entire energy makeover will pay for itself in just over seven years ($43,000/$6,000 = 7.2). And because our loan for these improvements is based on home equity, the interest payments are tax-deductible.

Since we remain connected to the utility grid, Southern California Edison's time-of-use billing program measures our overall electricity consumption and production. Rates vary depending on season and peak versus off-peak hours. With normal sunshine, we can actually see our meter "feeding the grid." Our electricity production earns us "use-it-or-lose-it" credit from the utility. In summer peak hours (10 a.m. to 6 p.m.), we can earn over 40 cents per kilowatt-hour; even during off-peak summer hours and in winter, we can earn credit. Each year, our credit amounts to between $200 and $300.

It's true that we live in warm, sunny California, which has some of the best rebates and tax incentives for going solar in the nation. But wherever you live, you can benefit from energy-efficiency and renewable-energy upgrades to your existing home and become part of the solution to global warming. See Resources for more general information. For more specifics on the Williamsons' retrofit, see this article published in Solar Today Magazine, from which our feature was drawn.

Looking Forward, an Energy Scramble or a Blueprint?


Share/Bookmark
This article is long and worthwhile reading. Follow the link for more detailed information.
Like many institutions and individuals, Shell, the oil giant, is trying to divine what lies ahead in a world with limited energy options, a fast-growing energy appetite, and a climate system almost assuredly disrupted should carbon dioxide emissions from today’s fuels of choice continue their seemingly inexorable rise.
Earlier this month, the company’s forecasters produced two energy scenarios for the next two generations, which they call “the world of scramble” and the “world of blueprints.”
In 2002, I wrote about a report, “Great Transition,”
ranging from Eco Communalism to Fortress World.”

There’ll be instability, poverty, overpopulation, and pollution in some places (they tend to go hand in hand, as in Haiti)

Wind Power Becoming More Affordable


Share/Bookmark
clipped from wnyt.com

Making electricity from wind is becoming a realistic option.

A wind turbine system suitable for powering a family house or small farm is now priced at about 15-thousand dollars, according to conference participants.
Almost all of the expense is upfront, so that after seven or eight years at current rates the cost is paid back and the owner is now enjoying basically free electricity.
The wind doesn't always blow, so a wind turbine owner would need to stay on grid, have back up generators or other sources of power for complete reliability. But if it means reducing demand for current sources of juice, increasingly people are saying where do I sign up?
Although it is non-polluting and renewable, there are real problems with wind power, including visual impact objections and risk to flying birds. For wind to be fully utilized those problems will have to be worked out.

$100 million investment to help solar energy plan


Share/Bookmark

Under an agreement announced yesterday, Phoenix-based Stirling Energy Systems said it has landed a $100 million investment from NTR, an international holding company in Dublin, Ireland.
for Stirling, which has come under fire from environmentalists who question Stirling's role in the 150-mile Sunrise Powerlink proposed by San Diego Gas & Electric Co.
the Arizona startup with 40 employees plans to develop a power plant, consisting of 12,000 solar energy dishes, near El Centro at an estimated cost of $400 million.

The plant would generate enough electricity for nearly 300,000 homes in San Diego
Environmentalists say they are skeptical of the Stirling proposal. They doubt that the company can move from its prototype models to large-scale production in time to enable San Diego Gas & Electric to meet a statewide mandate that requires it to use renewable energy for 20 percent of its total power supply by 2010.

Stern Reality: Is Global Warming Even Worse than You Thought?

Nicholas Stern, author of the gloomy, eponymous review that sparked a debate among environmental economists in 2006, said he was wrong. Things are actually much worse. From the Independent:
“We badly underestimated the degree of damages and the risks of climate change,” said Lord Stern in a speech in London yesterday. “All of the links in the chain are on average worse than we thought a couple of years ago.” […]He also reiterated his previous estimates that governments and business must invest the equivalent of between 1 to 2 per cent of global GDP annually up to 2050 in new technologies and efficiency measures or face climate change of catastrophic proportions.

Moore’s Law: Why Enviros Are Wrong on Nuclear Power


Share/Bookmark
Happy looking guy. Contemplating or a case of agita?
clipped from blogs.wsj.com
Greenpeace co-founder Patrick Moore’s cheerleading for nuclear power is hardly news these days
Mr. Moore, who now works as a nuclear-power advocate with the Clean and Safe Energy coalition, drops a few interesting pearls in an interview this week with Fareed Zakaria, the editor of Newsweek International.
[W]e made the mistake of lumping nuclear energy in with nuclear weapons, as if all things nuclear were evil. I think that’s as big a mistake as if you lumped nuclear medicine in with nuclear weapons.
[S]olar is completely ridiculous. The cost is so high—California’s $3.2 billion in solar subsidies is all just going into Silicon Valley companies and consultants. It’s ridiculous.
Unfortunately now the environmental movement is the primary obstacle here. If it weren’t for their opposition to nuclear energy, there would be a lot fewer coal-fired power plants in the United States and other parts of the world today.

Professor delivers 'Lecture': Randy Pausch's The Last Lecture makes its debut at No. 2 on USA TODAY's Best-selling Books list, but Pausch, who is dying of pancreatic cancer, says sales aren't the reason he wrote the book.
"I personally only cared about the first three copies, which are for my kids," he says. The book, written with Wall Street Journal columnist Jeff Zaslow, builds on a "last lecture" Pausch gave in September at Carnegie Mellon. Many in the publishing world believe Lecture will be the next Tuesdays With Morrie, which became a publishing sensation. It, too, dealt with wisdom imparted by a dying professor.

New Ways to Store Solar Energy for Nighttime and Cloudy Days


Share/Bookmark
clipped from www.nytimes.com
Solar power, the holy grail of renewable energy, has always faced the problem of how to store the energy captured from the sun’s rays so that demand for electricity can be met at night or whenever the sun is not shining.
The difficulty is that electricity is hard to store. Batteries are not up to efficiently storing energy on a large scale. A different approach being tried by the solar power industry could eliminate the problem.
Storing Solar Energy


Storing Solar Energy

The idea is to capture the sun’s heat.
Solar thermal systems are built to gather heat from the sun, boil water into steam, spin a turbine and make power, as existing solar thermal power plants do — but not immediately. The heat would be stored for hours or even days, like water behind a dam.
“You take the energy the sun is putting into the earth that day, store it and capture it, put it into the reservoir, and use it on demand,”

Rocky Politics: The Coal Question

Which weighs more this election year—the economy, or the environment?

This was supposed to be the year the environment and climate change reached a political tipping point
For the Democrats, the issue is especially prickly. As the WSJ reports today (sub reqd.), coal has become part of the political battlefield as the primaries wind down:
The race for the Democratic nomination hinges on a handful of states where coal is still king. That puts Senators Hillary Clinton and Barack Obama in a bind: how to attack global warming without threatening an industry that provides half the U.S.’s electricity and more than 80,000 mining jobs.
