EUROPA - Press Releases - How is Europe doing in clean technologies? Visit the new Commission's online assessment system

  • Today, the Commission launches "SETIS", the online Strategic Energy Technologies (SET-Plan) Information System, which provides the latest research results on the status, forecasts and R&D investment figures for low-carbon technologies. It underpins the effective strategic planning, conception and implementation of EU energy technology policy and serves notably to the implementation of the Strategic Energy Technology Plan (SET Plan). SETIS assesses and monitors those technologies that have a significant potential to help Europe meet its energy and climate change targets, such as wind power, solar power, CCS or bioenergy. The Information System offers interactive tools to compare the maximum potential and energy production costs foreseen for the different technologies over time.

Research

  • We examine the potential economic implications of
    using vehicle batteries to store grid electricity generated at off-peak
    hours for off-vehicle use during peak hours. Hourly electricity prices in
    three U.S. cities were used to arrive at daily profit values, while the
    economic losses associated with battery degradation were calculated based
    on data collected from A123 Systems LiFePO4/Graphite cells tested under
    combined driving and off-vehicle electricity utilization. For a 16 kWh
    vehicle battery pack, the maximum annual profit with perfect market
    information and no battery degradation cost ranged from ~$140 to $250 in
    the three cities. If the measured battery degradation is applied, however,
    the maximum annual profit (if battery pack replacement costs fall to
    $5,000 for a 16 kWh battery) decreases to ~$10-$120. It appears unlikely
    that these profits alone will provide sufficient incentive to the vehicle
    owner to use the battery pack for electricity storage and later
    off-vehicle use. We also estimate grid net social welfare benefits from
    avoiding the construction and use of peaking generators that may accrue to
    the owner, finding that these are similar in magnitude to the energy
    arbitrage profit.

Eight Increasingly Affordable Home Remodels - Forbes.com

  • In that particular case, he says, the materials comprised only 10% to 20% of
    the cost. But the customer was right to ask for a deal, since the price of lumber
    is down 2%, steel
    is down 9% and copper is down 11% from a year ago, according to the American
    Institute of Architects.

Brilliant New Book Teaches You How to Evaluate Sustainable Energy Claims « Johnny Rook’s Climaticide Chronicles

  • Unsettlingly, usually, these discussions involve more strong opinions than data. Some people believe that one of these alternative (they are not all sustainable) energy options is the silver bullet that will solve both the climate and the energy crisis. Other argue that there is no silver bullet and that what is required are a variety of silver BB’s: a mixture of technologies, along with greater energy efficiency and preservation of habitat (forests). Do we really just need to build huge number of nuclear plants or wind farms to solve the problem? If, instead, we are going to use a mix of alternative energy sources, which ones should we use and in what quantities?

PV's "Moore's Law" Required To Drive Increased Material Efficiency

The road to grid parity for PV power generation will be difficult, needing five or more years to compete with utility power, unsubsidized, on a large scale, noted Mark Thirsk, managing partner at Linx Consulting, at a recent SEMI PV forecast luncheon (Sept. 18) in Santa Clara, CA.

Benefits of System Loss Reduction « HEAD, WIND, CANOE

    • Aside from impacting or not impacting electricity rates, system loss reduction has the following benefits:


      • Reduction of fuel emissions due to lesser use of fossil-fuel generating plants - this has societal impact as it cover environmental concerns.
      • Utility system capacity savings - decrease in losses provides released extra capacity for the distribution lines and transformers.
      • Promotion of Energy Efficiency - it will be noted that the Distribution Utility (DU) is an energy-efficient electric company as it tries to decrease its system loss.
      • Improvement of system voltage profile - the utility is regulated to supplying a range of voltage level and reduction of losses will produce a marginal system voltage quality that may be acceptable. This will also provide good power quality at the convenience outlets of consumers allowing their electric equipment/appliances to operate without mis-operation or loss of life.
      • Increase Utility Commercial Appeal - a DU aiming at system loss reduction gets an added commercial appeal in the restructured power industry. This is important in the changing environment of the power industry, have you seen MERALCO TV commercials?

Joel Makower: Two Steps Forward: The Latest Reports: Solar Utilities, Carbon Offsets, and the Emperor's New Clothes

  • My colleagues at Clean Edge have just released the Utility Solar Assessment (USA) Study, making the case that solar power has the potential to reach cost parity with retail-electricity rates in most regions of the U.S. in less than a decade — but only if electric utilities step up to the plate.

Germany's Solar Cell Promotion: Dark Clouds on the Horizon | Leonardo ENERGY

  • This article demonstrates that the large feed-in tariffs currently guaranteed for solar electricity in Germany constitute a subsidization regime that, if extended to 2020, threatens to reach a level comparable to that of German hard coal production, a notoriously outstanding example of misguided political intervention. Yet, as a consequence of the coexistence of the German Renewable Energy Sources Act (EEG) and theEUEmissions Trading Scheme (ETS), the increased use of renewable energy technologies does not imply any additional emission reductions beyond those already achieved by ETS alone. Similarly disappointing is the net employment balance, which is likely to be negative if one takes into account the opportunity cost of this form of solar photovoltaic support. Along the lines of the International Energy Agency (IEA 2007:77), we therefore recommend the immediate and drastic reduction of the magnitude of the feed-in tariffs granted for solar-based electricity. Ultimately, producing electricity on this basis is among the most expensive greenhouse gas abatement options.

The Oil Drum: Europe | A Little History of the Affordability of Domestic Energy in Great Britain

  • The chart above shows domestic fuel prices for Great Britain from 1914 to 2007. The data up to 1985 was compiled by Horace Herring and Rodney Evans using this source and been updated with more recent figures from UK government statistics. It is expressed in UK pounds for the year 2000, adjusted by the retail price index (i.e the price of energy related to other 'real' goods such as food).

Electronic Component Suppliers - Electricity Storage Association - electric utility, esco

  • While capital cost is an important economic parameter, it should be realized that the total ownership cost (including the impact of equipment life and O&M costs) is a much more meaningful index for a complete economic analysis. For example, while the capital cost of lead-acid batteries is relatively low, they may not necessarily be the least expensive option for energy management (load leveling) due to their relatively short life for this type of application.

Flat Panel Technology Boosts Solar Efficiency

  • Xtreme Energetics has investigated the possibility of using mechanical trackers to perform the same light-focusing duties as other solar array manufacturers have. However, HP’s transparent transistor can do the job electronically, rather than mechanically, and significantly reduce the costs of such an installation. Such a solar array is known as a concentrating photovoltaic (or CPV) solar array. To date, CPV arrays are fairly expensive and cannot store energy, making them less useful. They also work best in specific sections of the world — those with the highest levels of solar radiation, such as the southwest United States and northern Africa.

IEEE Spectrum: Plugging Away in a Prius

  • In October, Sawyer paid US $25 000 for a brand-new
    black 2008 Toyota Prius. But compared with his RAV4 EV,
    it was a gas guzzler, going only 1 or 2 km electrically
    before switching on its internal combustion engine. So
    Sawyer wrote a check for the car, then drove it directly
    to Hybrids Plus [see our sidebar,"Getting on the Grid"],
    also in Boulder, where he wrote another check, for $32
    000—to have his shiny new Prius converted into a PHEV.
    (The radio-telemetry business has been very good to Sawyer.)

Rhein on Energy and Climate : Bright Prospects for PV electricity

  • The leading Norwegian manufacturer of photovoltaic cells and panels expects PV power generation costs to decline to only 8 cents/kWh as of 2010, provided installations benefit from at least 1800 hours/year of sunshine. That is the case in the countries around the Mediterranean, the southern parts of the USA, India, China, Australia and many other parts of the planet.

The Oil Drum: Europe | Why wind needs feed-in tariffs (and why it is not the enemy of nuclear)

  • An argument often heard against wind is that it costs a lot in public subsidies for a solution that will always have a limited

    impact (because it still produces only a small fraction of overall needs, and because of its unreliability linked to its

    intermitten nature). This is an argument worth addressing in detail, especially when it is pointed out, as the graph shows, that

    wind is already almost competitive with the other main sources of electricity, which suggests that it might not even need

    the subsidies then (and the increase in commodity prices since that graph was prepared using 2004 data, only reinforces that

    argument).

Research

  • The price of delivered electricity will rise if generators have to pay for
    carbon dioxide emissions through an implicit or explicit mechanism. There
    are two main effects that a substantial price on CO2 emissions would have
    in the short run (before the generation fleet changes significantly).
    First, consumers would react to increased price by buying less, described
    by their price elasticity of demand. Second, a price on CO2 emissions
    would change the order in which existing generators are economically
    dispatched, depending on their carbon dioxide emissions and marginal fuel
    prices. Both the price increase and dispatch changes depend on the mix of
    generation technologies and fuels in the region available for dispatch,
    although the consumer response to higher prices is the dominant effect. We
    estimate that the instantaneous imposition of a price of $35 per metric
    ton on CO2 emissions would lead to a 10% reduction in CO2 emissions in PJM
    and MISO at a price elasticity of -0.1. Reductions in ERCOT would be about
    one-third as large. Thus, a price on CO2 emissions that has been shown in
    earlier work to stimulate investment in new generation technology also
    provides significant CO2 reductions before new technology is deployed at
    large scale.

Reasons to see red over green energy | Environment | The Guardian

  • How bad is the situation? Well, BERR handed out grants for part of the cost of fitting solar photovoltaic systems covering only 270 houses last year. The Germans fitted 130,000. We have a total installed capacity (including commercial) of 16 Megawatt peak (Mwp). They have 3,800 Mwp.
