Record $260 Billion Invested in Clean Energy in 2011 | Solar Thermal Magazine - 0 views

  • 2011 highlights include a 36% surge in total investment in solar technology, to $136.6bn. This was nearly double the $74.9bn investment in wind power, which was down 17% on the previous year
  • The performance of solar is even more remarkable when you consider that the price of photovoltaic modules fell by close to 50% during 2011, and now stands 75% lower than three years ago, in mid-2008. The cost of PV technology has fallen, but the volume of PV sold has increased by a much greater factor as it approached competitiveness with other sources of power.”

Discovery May Allow Doubling of Solar Panel Efficiency! | Solar Thermal Magazine - 0 views

  • University of Texas at Austin stating that one of its chemists has discovered a way that may allow solar panel efficiency to be doubled, possibly reaching as high as 66%
  • “At current, approximately 31% insolation-to-electricity efficiency of a silicon solar cell is considered to be the maximum in the solar industry,”
  • “Being able to cheaply double the efficiency and even being able to reach 66% efficiency could potentially erase the barriers of competing with cheap fossil fuels very quickly.”

Why less is more: how thin film manufacturing is finding momentum - ElectroIQ - 0 views

  • Today, silicon wafers and PV modules are in more ample supply, and negotiating power has shifted back to the buyer, though the near term outlook for c-Si components is somewhat uncertain because of accelerating demand. With cost leadership now a matter of survival in a tight PV market, the competitiveness of thin-film technologies has been challenged. However, a new generation of thin-film silicon technology is poised to regain cost leadership within the industry. Key innovations are helping to drive down cost and increase efficiency and reliability to reinforce thin film’s competitive advantages in end user markets.
  • Thin-film silicon PV modules require far less silicon than traditional methods (less than 1/100th of a wafer thickness) and use widely available, comparatively inexpensive materials.
  • Another key positive factor is that thin-film silicon technology uses only environmentally friendly, non-toxic substances. Finally, thin-film silicon panels have an inherent advantage in real energy performance, due primarily to the fact that thin-film silicon has a temperature coefficient “penalty” that is almost 50% lower than most conventional crystalline. In hot climates, this advantage results in 5% to10% higher output per installed watt compared to crystalline silicon.

New Year Prediction: Even Higher Costs and More Headaches Ahead for Nuclear Power in 20... - 0 views

  • There simply are too many other choices which provide greater certainty at lesser cost and without the enormous long-term unresolved problems and risks facing nuclear power.
  • Failure of voluntary, self-regulation; Denial of the reality of risk; Lack of safety culture; Lack of a comprehensive, consistent regulatory framework; The challenge of continuous change and the need to retrofit existing reactors; Failure to resolve important outstanding safety issues; Failure to require existing reactors to add safety measures because of cost; and Complexity, confusion and chaos in the response to a severe accident. With the global nuclear safety institutions expressing strong concerns, particularly the advanced industrial nuclear nations, and the aftermath of Fukushima likely to command attention for years as the extent of the damage and the challenge of decommissioning unfold, the issues are likely to continue to have traction. The reviews stimulated by accidents are not limited to safety issues. In the wake of Fukushima re-evaluations of energy options and nuclear risks and economics have substantially dimmed the prospects for construction of new nuclear reactors: Major policy reviews by governments have led several nations to decide to scale back or abandon their commitments to nuclear power (including important large industrial national like Japan and Germany); Financial institutions have conducted extensive reassessments of the economic prospects of nuclear power and concluded that the costs will rise (e.g. USB); Utilities with nuclear plants in several nations have been downgraded by rating agencies; and Several major firms in advanced industrial nations have abandoned the sector or been forced to scale back their activities (e.g., Shaw Group, Siemens and Areva). As the Cooper paper concludes: “As all stakeholders re-examine all aspect of energy policy, the risks of nuclear reactors increase and the attractiveness of nuclear power compared to other options decreases.”

Electric vehicle battery cost reductions won't pay off next year - ElectroIQ - 0 views

  • According to data from Pike Research’s annual Electric Vehicle Consumer Survey, the optimal price for a plug-in electric vehicle (PEV) to engage consumers is $23,750, but a quick pricing check reveals distance between want and reality: 2012 Toyota Prius PHEV ($32,000), the Honda Fit BEV ($36,625), and the Ford Focus EV ($39,995) (before federal incentives). These relatively high selling prices will constrain the market for PEVs in 2012. Nevertheless, the global market for plug-in electric vehicles will grow to more than a quarter million vehicles in 2012.
  • Car-sharing services will expand the market for EVs and hybrids. Battery production will outstrip vehicle production. The Asia-Pacific region will become the early leader in vehicle-to-grid (V2G) systems. Third-party EV charging companies will dominate public charging sales. Employers will begin to purchase EV chargers in large numbers.  EVs will begin to function as home appliances.

Grid Parity for Solar PV with Balance of System Cost Reductions | john-farrell-ilsr - 0 views

  • Cutting non-module solar PV costs with best design practices could make solar PV cost less than grid electricity for more than 25 percent of Americans.
  • how to reduce balance of system costs by 58 percent in five years.
  • They found that the balance of system savings (and induced reduction in module costs) could lower the price of solar PV electricity from 22 cents per kWh to 8 cents per kWh. 
  • ...1 more annotation...
  • To put that in context, I recently examined distributed solar's cost compared to grid electricity prices, concluding that "solar PV at $5 per Watt (with solely the federal tax credit) could not match average grid electricity prices in any of the sixteen twenty largest metropolitan areas in the United States."

Busting 4 Myths About Solar PV vs. Concentrating Solar Power | john-farrell-ilsr - 0 views

  • A concentrating solar power plant has a capital cost of $5.50 per watt without storage, and $7.75 per watt with six hours of thermal storage. The levelized cost of electricity from a Mohave Desert concentrating solar power plant (without storage) serving Southern California load is $250 per megawatt-hour (MWh), or 25 cents per kilowatt-hour (kWh).  With the federal investment tax credit, the price is 17.5 cents.* In contrast, a distributed solar PV plant has a capital cost of $3.80 per watt without storage and can add battery storage for $0.50 per watt. Thus, a PV plant with six hours of storage would cost $6.80 per watt. Because a distributed solar PV plant also has no need for long-distance transmission, the levelized cost of solar PV (without storage) in Southern California is $136 per MWh, or 13.6 cents per kWh (9.5 cents with the federal tax credit). The levelized cost for concentrating solar and solar PV with storage (and the federal tax credit) are 23 and 16.8 cents per kWh, respectively.
