The purpose of the "super-grid", of which in a very small way the new Irish inter-connector is an example, is that wind power (and PV) surpluses in one part of Europe will find value and be exported to other parts of Europe where and whenever there is a dearth.

Macquarie Equities Research said in a client note several days ago that energy efficiency measures really do seem to be having an impact on electricity demand, and the effect is likely to continue. It’s not just theoretical or wishful, the analysts said. “Unfortunately for investors,” the firm said, “utilities expect this demand destruction to continue or even accelerate.” A couple of electric utilities said pretty much the same thing. According to a Macquarie survey of utilities, to which 43 responded, most expect slow demand growth, less than 1% a year, significantly less than the historical rate of about 2%. The economy is partly to blame for flat or small growth in demand over the last several years — and some respondents see the economy as the bigger driver — but “more than half of utilities estimate that energy efficiency has reduced their load growth by up to 1% per annum, with nearly an additional quarter estimating a reduction of up to 0.5%.” What is energy efficiency doing to power demand?

Five big energy problems for the 21st century | FT Energy Source A piece by academic and author Vaclav Smil in the OECD Observer (undated, unfortunately) paints a gloomy picture of energy transition this century: An impartial examination of some basic principles reveals five factors that will make the transition to a non-fossil world far more difficult than is commonly realised. These are: the scale of the shift; the lower energy density of the replacement fuels; the substantially lower power density of renewable energy extraction; intermittency of renewable flows; and uneven distribution of renewable energy resources.

Super-grid gets super-serious, but does it rely too much on Norw The plan for a European ‘super-grid’ being proposed today by 10 companies, including Siemens of Germany and France’s Areva , might sound ridiculously over-ambitious. Cynics are already noting that most of the members of the group would be direct beneficiaries of the vast amounts that would have to spent building the super-grid. But this is a project that has already won serious political backing from nine EU member states and Norway, and, at least in its most modest version, looks like a realistic prospect. The 10 companies comprising the ‘Friends of the Super-grid’ group would like the connections eventually to encompass most of the countries of north-west and south-west Europe, like this:

Wind resistance: Analysis suggests generating electricit Wind power has emerged as a viable renewable energy source in recent years -- one that proponents say could lessen the threat of global warming. Although the American Wind Energy Association estimates that only about 2 percent of U.S. electricity is currently generated from wind turbines, the U.S. Department of Energy has said that wind power could account for a fifth of the nation's electricity supply by 2030. But a new MIT analysis may serve to temper enthusiasm about wind power, at least at very large scales. Ron Prinn, TEPCO Professor of Atmospheric Science, and principal research scientist Chien Wang of the Department of Earth, Atmospheric and Planetary Sciences, used a climate model to analyze the effects of millions of wind turbines that would need to be installed across vast stretches of land and ocean to generate wind power on a global scale. Such a massive deployment could indeed impact the climate, they found, though not necessarily with the desired outcome.

That in turn "has an effect on investors" and profit On some nights in northern Germany, utilities pay customers to keep their lights on. In a country with deep green roots, it's an odd fix for an odd problem: Local distributors have no place to store wind energy and no way to dispatch it to areas that need it. That's led to so-called negative pricing, where grid operators pay utilities to take the unneeded power. Then utilities like RWE and EnBW of Germany give rebates to customers who use power during periods of excess. Sometimes wind farm operators are even asked to take their turbines offline to trim supply, lowering green operators' profitability. Where Wind Power Is Blowing Away Profits
Mixed messages on offshore wind’s future | FT Energy Source | FT Mixed reports have been published recently about the current state and future potential of the UK offshore wind industry. While one paper last week suggested offshore wind could provide all our electricity needs by 2050, another recently commissioned report is looking into the threat posed by escalating costs of the technology. First, the bullish view. This comes from the Offshore Valuation Group, a coalition of government and industry organisations including The Department for Energy and Climate Change, the Welsh and Scottish governments and companies active in offshore wind such as E.on and DONG Energy.
Wind Costs: Connecting Some Dots — MasterResource There has not been much published on wind costs, except, generally speaking to give the impression that they are reasonable and manageable. Unfortunately, at the level of wind implementation being contemplated, particularly in the Western world, the costs are an unsupportable amount of national wealth.
