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.

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.”

Most Germans Don't Choose Green Energy | phockeno - 0 views

  • In total, only 10 percent of German households have switched to 100-percent renewable energy providers
  • The main reason Germans do not switch providers is still fear. "For years the big utilities waged campaigns explicitly designed to instill this fear. They implied that you could wind up with no power at all if you tried to switch,"
  • "Thus many people have trouble trusting a new company."

  • More people will switch when they're cheaper than the alternatives. But the current government is blocking this."
  • We need to beef up renewable energy capacity, which means maintaining the feed-in tariff for many years to come, and also to expand the green power market as much as possible."

Here Comes the Sun - The Chart Paul Krugman Left Out | john-farrell-ilsr - 0 views

  • rid electricity prices are not fixed, but changing.  Over the past decade, electricity prices have risen, on average across the United States, 3 percent per year.  The solar electricity price is locked in once the panels are operating. Some utilities have time-of-use rates that charge more for electricity during peak times (hot, summer afternoons) that rise as high as 30 cents per kWh.  Solar competes favorably against these rates. There are federal, state and utility incentives for solar that reduce the cost.  The 30% federal tax credit, for example, is in statute until the end of 2016.
  • The first step is translating solar prices into electricity prices.  Installed costs for solar have dropped dramatically, from $8 to $10 per Watt just a few years ago to as low as $3.50 per Watt for utility-scale systems as just over $4 per Watt for residential systems.  But electricity isn't sold in Watts, but in kilowatt-hours (kWh).  So, solar installed at $3.50 per Watt in Minneapolis, MN, will produce electricity for about 23 cents per kWh.  In sunny Los Angeles, the same solar PV array would produce power at 19 cents per kWh, because the more abundant and direct sunshine would make 20% more solar electricity over the same time period.
  • by the time their solar PV systems are halfway to their expected life of 25 years, 45 million Americans (roughly 1 in 6) would have cheaper electricity from solar if they installed right now at $3.50 per Watt.

Clean Energy Expert Tam Hunt: Rapid Clean Energy Growth Inevitable | MCasey - 0 views

  • Where global wind power has grown about 25 percent per year in the last decade, global solar power has grown an average of 68 percent each year over the last five years (including Bloomberg New Energy Finance projections of 28 GW of new solar in 2011). This is a doubling literally every 1.3 years. So today’s 40 GW of capacity becomes, under the same growth rate, an astronomical 1.3 million GW by 2030. Obviously, the recent rate of growth won’t continue because, among other reasons, this is far more power than we need for the entire globe! But even if solar power’s rate of growth drops in half to 35 percent over the next two decades, this produces a doubling every 2.3 years and we get 16,000 GW (16 terawatts) by 2030 – almost as much as the entire world will need by then.
  • keep in mind that clean energy doesn’t come with the enormous health and economic costs that are inherent to dirty energy, such as the $500-billion-per-year cost of coal in the United States alone
