Wind is shelved from the Pickens Plan

The 2008 “Pickens Plan,” U.S. financier T. Boone Pickens’ proposal to reduce U.S. dependence on foreign oil, anticipated that 20% of American power generation could come from wind while natural gas could power the nation’s transportation sector. At the time, he received support from unlikely sources, including the executive director of the Sierra Club, Carl Pope.

Pickens’ interest in wind generation, however, has been steadily decreasing since his plan was initially announced, and in a recent interview with Roll Call, he said he’s entirely shelving the wind portion of his plan. According to Pickens, wind is not financially viable because natural gas is too cheap. Until the cost of natural gas rises, wind generation doesn’t make economic sense. In the meantime, he is focusing entirely on getting natural gas into the energy market.

The move has produced a backlash from some of the environmentalists that formerly supported the Pickens Plan. They accuse Pickens of lobbying for incentives in order to make more money off natural gas, and they complain that the natural gas industry is too unregulated to be considered a clean source of fuel. The process known as “fracking,” which is used to produce natural gas, has been questioned as a possible source of groundwater contamination.

Meanwhile, supporters of wind power say Pickens’ move shouldn’t be seen as a reflection of the health of the wind industry as a whole, but as how things happen to be playing out in Texas at this particular time. Wind industry analyst Matt Kaplan, with IHS Emerging Energy Research, told Climate Progress that it’s very difficult right now for wind farms to beat out natural gas on the spot market. It’s also difficult for developers to find long-term agreements in Texas since Texan utilities have already purchased enough wind power to fulfill their required targets. Other markets, however, still have a lot of room for renewable energy development. California and the Northeastern states, in particular, are willing to sign power purchase agreements. Overall, Kaplan thinks development will stay relatively flat until the price of natural gas begins to rise.

“We think it’s really a more healthy trajectory for the industry – this moderation is going to make wind more cost competitive over the long term by forcing companies to improve technology, build better projects, and reduce costs,” Kaplan told Climate Progress.

Peter Kelley, the vice president of the American Wind Energy Association, told Roll Call, “We agree [with T. Boone Pickens] that natural gas prices won’t stay as low as they are today for very long, and that’s one of the reasons we believe wind energy needs to be a bigger part of our energy mix all along, so electric utilities can lock in long-term low rates today.” Indeed, Pickens’ organization stresses that wind power is still an important piece of America’s energy independence. They’re just not building large wind farms in Texas for the time being. Considering Pickens expects natural gas prices to rise by 2016, however, we have to wonder why it doesn’t make sense to continue planning for wind farm construction now.

Obama’s drilling plan

President Obama announced last Saturday that, in an effort to promote greater domestic oil production and help relieve prices at the fuel pumps, he intends to expand oil and gas drilling in the Gulf of Mexico and Alaska. The move was apparently meant to appease voters that are angry over soaring gas prices. At the same time, Obama has continued to press for repealing $21 billion in tax incentives for the big oil companies.

This isn’t the first time Obama has proposed expanding drilling. On March 31, 2010, he also announced the need to open more areas to gas and oil drilling. At that time, environmentalists sharply criticized the move and Republicans only offered lackluster support. The BP oil spill that occurred in the Gulf of Mexico a few weeks later effectively killed the proposal, with the administration placing a moratorium on deep water drilling.

This time around, Obama wants the Interior Department to allow drilling in Alaska’s National Petroleum Reserve. He also called for the faster evaluation and leasing of new oil and gas areas in the Gulf of Mexico. Obama cautioned that, “while there are no quick fixes to the problem [of high gas prices], there are a few steps we should take that make good sense.”

Some have argued that the proposal is aimed more at voter psychology than good sense. It’s unclear whether the move would have much effect on gas prices. It takes a long time for a policy change to produce a noticeable rise in oil production. Moreover, oil is a fungible global commodity. The price is determined by global supply and demand. If China is willing to pay more for oil than America, oil companies will only be too happy to send Alaskan oil overseas. The only way drilling for more oil in America would appreciably alter the price of gasoline is if the oil industry were nationalized.

However, there are ways in which the move does make good sense. Obama now looks like he’s doing something, energy markets usually respond positively to the prospect of greater future oil supplies, and real jobs will be created. The effect on the markets and the creation of jobs are especially welcome as the economy continues to slowly recover.

US State Dept. finds no new issues with Keystone XL

Keystone XL is back in the news! Keystone XL, the controversial 1,900-mile pipeline carrying Canadian bitumen from Alberta to refineries as far south as Houston TX, passed another hurdle recently when an updated environmental report from the State Department found no new issues with the proposed pipeline since a similar report was issued last year.

Environmentalists have fought the production of Canada’s oil sands, citing the destructive nature of its production (primarily through strip mining) and the intensive amounts of energy required to extract the oil (known as bitumen) from the sand. They further argue that the corrosive nature of bitumen could eventually damage the proposed pipeline and increase the risks of a spill in areas where a major aquifer (the Ogallala) is most vulnerable to contamination.

Supporters of the project point out that Canada regulates its energy production, requires mitigation and reclamation costs to be included in development, and is a stable and reliable source of energy for the U.S. The proposed pipeline could significantly reduce U.S. dependence on Middle Eastern oil. Moreover, the Canadian reserves are significant.

The Associated Press (AP) reported that Susan Casey-Lefkowitz, the international program directory for the Natural Resources Defense Council, claimed the report didn’t adequately address pipeline safety, including the risks posed to the Ogallala Aquifer. “If this round of the Keystone XL tar sands pipeline environmental review is as superficial as it seems, the State Department will need to go back to the drawing board — perhaps the third time will be a charm and they will get it right,” she told the AP. A spokesman for TransCanada, the Calgary-based company behind the pipeline, said the company was pleased with the State Department’s report but declined to comment specifically.

Approval of the pipeline has been held up since the Environmental Protection Agency asked the State Department for the additional environmental report last summer. The State Department, which has authority over the pipeline since it crosses an international boundary, is expected to decide on approval of the pipeline by the end of the year.

We’re No. 17! We’re No. 17!

Wind turbines (Vendsyssel, Denmark)

The Associated Press (AP) is reporting that a study (to be released May 9) commissioned by the World Wildlife Fund for Nature (WWF) and prepared by Roland Berger Strategy Consultants ranks the U.S. 17th in clean energy production. Denmark earns the top spot, with 3.1 percent of its gross domestic product (GDP) coming from clean tech (about $9.4 billion).

The report used data gathered from various energy and financial sources, like the International Energy Agency or bank and brokerage reports, to measure earnings from green energy technologies. These included not only energy production from renewable sources, such as biofuels, solar, or wind, but energy efficiency technologies as well. The countries were then ranked according to the amount of national revenue generated from these technologies. In other words, the percentage of a country’s GDP that came from clean tech determined its rank.

The report also looked at the pace of growth. The AP quotes Roland Berger Strategy Consultants’ senior research associate Ward van den Berg as saying, “Clean technologies are really growing fast, but China is responsible for the majority of that growth.” The report ranks China second, but says its production of green tech has grown a whopping 77 percent a year. This accounts for the largest earnings stated in the report, about $64 billion, which is 1.4 percent of China’s GDP. Donald Pols, an economist with the WWF, told the AP, “The Chinese have made, on the political level, a conscious decision to capture this market and to develop this market agressively.”

Pols went on to say that U.S. clean tech had grown substantially thanks to the policies of Obama, but this couldn’t compare to Chinese policies and Chinese growth. “When you speak to the Chinese, climate change is not an ideological issue. It’s just a fact of life. While we debate climate change and the transition to a low carbon economy, the debate is passed in China. For them it’s implementation. It’s a growth sector, and they want to capture this sector,” Pols told the AP. The U.S. generates about $45 billion from clean tech, representing 0.3 percent of its GDP.

According to the report, the top five producers in terms of percentage of GDP, in order of rank, are Denmark, China, Germany, Brazil, and Lithuania.

Surprising effect of light could change solar power generation

The University of Michigan has announced that researchers have discovered a surprising magnetic effect of light that could lead to solar power generation that doesn’t require the traditional semiconductor-based solar cells.

Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics and an author of a paper on the work, said the researchers had found a way to make an “optical battery.” This overturns a century-old tenet of physics.

Light has both electric and magnetic components. Until now, researchers thought the effects of the magnetic field were so weak that they could be ignored. But Rand and his colleagues discovered that, at the right intensity and when light is traveling through a non-conductive material, a magnetic effect can be generated that is 100 million times stronger than previously expected. This is equivalent to a strong electric effect.

“This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation,” Rand said. “In solar cells, the light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load. Instead of the light being absorbed, energy is stored in the magnetic moment. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power source.”

This new technique could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in converting solar power to useable energy. That’s equivalent to today’s commercial-grade solar cells.

The paper is titled “Optically-induced charge separation and terahertz emission in unbiased dielectrics” and has been published in the Journal of Applied Physics. You can read the University’s press release on their website.

EVs land in Antarctica

The National Renewable Energy Laboratory (NREL) has announced that McMurdo Station received two electric vehicles to help test whether the research station can move away from a dependence on diesel trucks. If the vehicles can handle the tough conditions at the remote station, they’ll help offset current fossil fuel use and pollution.

Transporting vehicle fuel to Antarctica is expensive, resource intensive, and requires a lot of planning, while both wind and solar (at least, for half the year) are plentiful on the ice. Moreover, McMurdo Station is considered a pristine research environment and anything that can be done to reduce pollution without jeopardizing operations would be helpful. Therefore, the National Science Foundation’s Office of Polar Programs is working with NREL and the Department of Energy to incorporate more renewable energy and efficiency practices into current facilities.

As part of that effort, NREL researched and tested e-ride Industries’ EXV2 electric utility vehicle. The units were chosen because the truck-like bed and larger utility-style tires more closely resembled the pick-up trucks currently being used. NREL subjected the vehicles to sub-zero temperatures and, after being assured they functioned as expected, outfitted them with insulation and battery heaters and sent them by boat and transport plane to McMurdo.

Since landing on the ice in February, the vehicles have been used on a daily basis, logging more than 70 hours and nearly 140 miles. The real test lies ahead, during Antarctica’s bad weather months. The vehicles will then be subjected to brutally cold conditions. “Empirical data on the capability of the vehicle batteries in such cold is critical,” NREL Senior Task Leader Ted Sears said. “As a result, we are trying to learn everything we can about how the vehicle systems operate and respond in the extreme cold. Despite the vehicles being equipped with battery warming devices, there are still going to be limitations on their capabilities.”

McMurdo isn’t the only facility looking at whether renewables can reduce fuel use. Remote locations the world over would benefit from similar vehicles. Currently these places have to ship fuel in at great cost.

Batteries not required: Wireless sensors promote building efficiencies

Wired’s Gadget Lab is reporting on a clever wireless energy sensor developed by EnOcean that can help manage energy efficiencies (and cut costs) in commercial buildings.

EnOcean is a spinoff of Siemens focused on making energy harvesting wireless sensors and transmitters. These devices harvest energy from the mechanical movement of light switches, swipe card readers, and door handles, or use the Peltier effect to extract energy from the temperature difference between surfaces, to power tiny transmitters. These transmitters can communicate on TCP/IP networks allowing for whole-building control.

“Most buildings today are dumb,” says EnOcean Chairman Graham Martin, “meaning they completely lack automation systems to manage energy use.” With EnOcean’s easy-to-install switches and thermostats in place, any internet-enabled device can communicate with the sensors to turn down the heat or shut off lights. And since the whole system is wireless, there’s no need to rip holes in walls to install automation systems.

While currently focused on commercial uses, EnOcean has its sights on more mainstream applications, such as homes. You can read more about how their technology works on their website.
