Worldwatch: Fossil fuel subsidies continue to outweigh those for renewable energy; international pledges on reform unfulfilled


Fossil fuel subsidies continue to far outweigh support for renewable energy, according to new research conducted for the Worldwatch Institute’s Vital Signs Online service. Although independent reporting on these subsidies has increased, global efforts to move forward with subsidy reform have been hindered by a variety of causes, leaving international pledges unfulfilled.
Total subsidies for renewable energy stood at $66 billion in 2010 (a 10% increase from the year before); the total value of global fossil fuel subsidies is estimated at between $775 billion and more than $1 trillion in 2012, Two thirds of the renewable energy subsidies went to renewable electricity resources and the remaining third to biofuels.
GSI: Fuel Subsidies in India
In 2011–12 India’s subsidies and under-recoveries for fuel totalled INR1.4 trillion (US$27.7 billion). Total subsidy expenditure (including for fertilizer and food) was up by 27% on the previous year, significantly contributing to the rise in fiscal deficit of 1.3% of the GDP for 2011–12, according to the International Institute for Sustainable Development’s Global Subsidies Initiative (GSI).
The Government has announced its goal of reducing total subsidy expenditure to 2% of GDP in 2012-13, with further reductions down to 1.75% in following years. However, reform has been hampered by concerns over how higher fuel prices will affect the broader economy—potentially disrupting key sectors like transport, industry and agriculture—and the ability of poor citizens to cope with higher prices.
GSI, in collaboration with the National Institute for Public Finance and Policy (NIPFP) and The Energy Resource Institute (TERI), released three new reports on India’s fuel subsidies and the options and recommendations for reform.
As an example, for diesel pricing the short-term recommendation is to progressively decontrol diesel prices by eliminating under-recovery over a period of around one year. For the medium term, the organizations suggest refining and implementing options investigated over the short term. For the long term, the recommendation is to liberalize diesel pricing.
Although the total subsidies for renewable energy are significantly lower than those for fossil fuels, they are higher on a per kWh basis (without including externalities). Estimates based on 2009 energy production numbers placed renewable energy subsidies between 1.7¢ and 15¢ per kWh, while subsidies for fossil fuels were estimated at around 0.1–0.7¢ per kWh. Unit subsidy costs for renewables are expected to decrease as technologies become more efficient and the prices of wholesale electricity and transport fuels rise.
Other findings from the Worldwatch report include:
  • Global production subsidies total an estimated $100 billion per year, and consumption subsidies add to roughly $675 billion.
  • In 2010, developing countries spent roughly $193 billion, or 47% of all fossil fuel consumption subsidies, on oil while industrial countries spent roughly $28 billion.
  • Since 2007, roughly 80% of spending on consumption subsidies occurred in countries that are net exporters of fossil fuels.
The US National Academy of Sciences estimates that fossil fuel subsidies cost the United States $120 billion in pollution and related health care costs every year. But these hidden costs (externalities) are not reflected in fossil fuel prices.
According to projections by the International Energy Agency (IEA), if fossil fuel subsidies were phased out by 2020, global energy consumption would be reduced by 3.9% that year compared with having subsidy rates unchanged. Oil demand would be reduced by 3.7 million barrels per day, natural gas demand would be cut by 330 billion cubic meters, and coal demand would drop by 230 million tons of coal.
The effects of the subsidy removal would extend beyond the end of the phaseout period. By 2035, oil demand would decrease by 4%, natural gas by 9.9%, and coal demand by 5.3%, compared with the baseline projection. Overall, carbon dioxide emissions would be reduced by 4.7% in 2020 and 5.8% in 2035.
The IEA’s chief economist recently estimated that eliminating all subsidies in 2012 for coal, gas, and oil could save as much as Germany’s annual greenhouse gas emissions each year by 2015, while the emission savings over the next decade might be enough to cover half of the carbon savings needed to stop dangerous levels of climate change.
Progress toward a complete phaseout, however, has been minimal. The 2009 pledge by the Group of 20 major economies to reduce “inefficient fossil fuel subsidies” has been left vague and unfulfilled, the Worldwatch Institute notes. The lack of a definition has left countries to make their own determination if their subsidies are inefficient. As of August 2012, G20 countries had not taken any substantial action in response to the pledge—six members opted out of reporting altogether (an increase from two in 2010), and no country has yet initiated a subsidy reform in response to the pledge. Furthermore, there continues to be a large gap between self-reported statistics and independent estimates in some countries.

Wind-Powered “Skypump” Fills Your EV With Clean Energy



The cleanliness of your EV is directly proportional to your source of electricity. If you’re drawing current from a coal-fired powerplant, well that isn’t very clean, is it? But a new wind turbine design from GE and Urban Green Energy cleverly called the “Skypump” uses a compact design with urban areas in mind to deliver clean energy to electric vehicles.
Using the power of wind to charge electric cars isn’t a new idea, though GE’s implementation of the Skypump is worthy of note. The compact design does away with huge propellers in favor vertical wind blades that require a minimum of 7 MPH winds to operate. The Skypump is hooked into one of GE’s DuraStation Level 2 EV chargers.
Standing at 42 feet high, and utilizing a compact blade design, the Skypump could fill in where traditional wind turbines are just too big. Each blade on some wind turbines can be as big as 160 feet long; the Skypump could easily see use in mall parking lots or industrial/business parks.
Don’t get me wrong; the Skypump won’t be solving the woes of EV users anytime soon. However, it can offer a genuinely green alternative to plugging into a coal-fired plug, and if this design proves effective, it could become quite commonplace.

ALTe To Develop Serial Plug-In Hybrid Drivetrains For Conversions

We need more and more companies like ALTe.

From Green Car Congress:

A Bloomfield, Michigan startup is developing light- and medium-duty series plug-in hybrid electric vehicle powertrain systems—initially as conversions, but ultimately extending to an OEM basis.

ALTe, LLC has initially targeted fleet applications—specifically, the New York Ford Crown Victoria taxi fleet—as the passenger car market does not drive enough miles per year to deliver the financial payback on the incremental cost of the conversion, said John Thomas, ALTe CEO, at the Business of Plugging In conference in Detroit last week.

ALTe already has Gen 1 proof-of-concept systems running in a Crown Vic taxi equipped with a 20 kWh Li-ion battery pack. In the Crown Victoria, the proof of concept powertrain conversion systems improve fuel economy from 80%-200% from the base 4.6L V8: from 14 mpg to up to 43 mpg, depending on vehicle use. With fleet mileage, ALTe projects ROI on a conversion in less than two years.

(Another benefit of targeting a conversion application such as the taxi fleet is that the vehicles are all out of warranty, Thomas noted.)

A Gen 2 Series PHEV Powertrain under development is installed in a running rolling chassis.

Thomas came to ALTe from Tesla Motors, where he was Senior Program Director and General Manager, and was working on “Whitestar”, later revealed as the Model S. Prior to Tesla, Thomas was Director of Special Projects at Magna Steyr, VP and Division General Manager at auto supplier Collins & Aikman, and a powertrain component design engineer and powertrain system project and project engineer for 10 years. ALTe is staffed by traditional auto industry and Tesla Motors alumni averaging more than 24 years of experience at major auto OEMs and suppliers in the US, Japan and Korea, Thomas said.

“The series plug-in hybrid is the best transitional powertrain technology due to cost and range issues of current battery science.”
—John Thomas

Thomas said that ALTe is building a robustly engineered, professional quality, mass production powertrain conversion kit assembly operation and plans to produce up to 90,000 powertrains per year. The company will deliver these powertrain kits to a dealer network to be established.

ALTe plans to develop series plug-in hybrid powertrains for a range of popular vehicles such as taxis, shuttle busses, pickup trucks, SUVs, etc, and is targeting more than $2 billion of revenues within five years.

The Mitsubishi iMiEV All-Electric Vehicle



The Misubishi iMiEV is the company's foray into the eco-friendly, green domain of auto manufacturers. It is a very compact all-electric vehicle that is scheduled to be introduced in the United States in 2009. Let's hope they can stick to that date as we need all the alternate energy vehicles we can get our hands on.

The iMiEV (what a name, huh?) is powered by three asynchronous AC motors which are capable of regenerative braking. This means that the motors turn into genereators when the driver taps the brakes and thus helps slow the car down while simultaneously adding electricity back into the battery pack. This technique allows the car to have a greater range, thus allowing the battery pack to be somewhat smaller in size. Speaking of the battery, Mitsubishi is using a 550 pound, 330 volt, 16 kWh Lithium ion pack. This is enough juice to propel the car for 70 miles or so. Personally, I would prefer the iMiEV to have a 24 kWh battery pack and more than 100 miles range as this would cover the overwhelming majority of daily commutes.

Here are some photos and specs from wired.com:

The iMiEV is an electric version of the "i," which belongs to a popular class of small vehicles called Kei cars. Although tiny — just a hair over 11 feet long — the iMiEV is surprisingly roomy inside because the wheels are pushed to the corners and the battery, motor and other electronics are located beneath the floor.

39_imiev_interior

The iMiEV is a real car, with all the amenities you'd expect to find in a compact or mid-sized car. Fit and finish is solid, though some of the plastic looked and felt cheap. Should the car ever make it to the United States, it will of course be left-hand drive.

The automatic transmission has three speeds, which might more accurately be called "modes." Drive ("D") provides full power. "Eco" tempers that by 10 percent and "B" maximizes regenerative braking to recover as much kinetic energy as possible and maximize battery life.

Dashboard display tells you how much battery charge you've got left in addition to things like how fast you're going and how far you've gone. You can't make it out in the photo, but the green display to the left of the gauge reads "Ready" and lights up once you've started the car. Electric motors are silent, so without the display you may not realize the iMiEV is running.

42_imiev_battery

The iMiEV uses a 16-kWh, 330-volt lithium-ion battery that weighs 550 pounds. It's located beneath the front seats. Mitsubishi is developing and building batteries under a joint venture with the Japanese firms GS Yuasa and MMC called "Lithium Energy Japan."

The battery charges in about 12 hours using a standard 110-volt household outlet. Double the voltage to 220 and you cut charging time in half.
