Capital-energy substitution: Evidence from a panel of Irish manufacturing firms - 2 views

  •  
    "We use a translog cost function to model production in the Irish manufacturing sector over the period from 1991 to 2009. We estimate both own- and cross-price elasticities and Morishima elasticities of substitution between capital, labour, materials and energy. We find that capital and energy are substitutes in the production process. Across all firms we find that a 1% rise in the price of energy is associated with an increase of 0.04% in the demand for capital. The Morishima elasticities, which reflect the technological substitution potential, indicate that a 1% increase in the price of energy causes the capital/energy input ratio to increase by 1.5%. The demand for capital in energy-intensive firms is more responsive to increases in energy prices, while it is less responsive in foreign-owned firms. We also observe a sharp decline in firms' responsiveness in the first half of the sample period."

» Demand Response and Renewables Integration Will Drive the Growth of Short-T... - 0 views

  • Due to the prohibitive cost of storing electricity on a major scale, short-term power markets are relied on to balance generation and load on a 24/7 basis.  These markets typically take the form of a day-ahead market that provides a preliminary forecast of the next day’s power generation and consumption, and a real-time market, which is used to balance the actual generation to load.

Engineering a Smart Grid For Energy's Future - washingtonpost.com - 0 views

    The process, Current says, lets a utility more efficiently manage the distribution of electricity by allowing two-way communication between consumers and energy suppliers via the broadband network on the power lines. Based on data they receive from hundreds of homes, utilities can monitor usage and adjust output and pricing in response to demand. Consumers can be rewarded with reduced rates by cutting back on consumption during peak periods. And computerized substations can talk to each other so overloaded circuits hand off electricity to underused ones, helping to prevent blackouts.

UK's huge push for wind power gets cool response - 0 views

    The target was greeted with wide skepticism, including from the Renewable Energy Foundation, which accused the government of "green exhibitionism".

    But note that Nick Jenkins supported the idea on TV News without reservation! Note also that around 40% - 13GW - of this generation would be off the coast of Scotland. The interconnectors to England (where the demand is) are about 2.5 GW and already fully loaded. Nobody talks about the need for connection.

3E Intelligence : 23% of Chinese CO2 emissions are our responsibility - 0 views

  • 23% of China’s CO2 emissions in 2004 were due to demand from the West for manufacturing products made in the new economic giant. This 23% is as much as the combined emissions from Germany and Australia and more than twice the national emissions of the UK.

  • “It’s not surprising there’s been little improvement in demand responsiveness given that a series of special rebates, the availability of fixed-term contracts, and the rules governing the behaviour of the Independent Market Operator combined to shield market participants from electricity price increases,”

Electric grid meets Web 2.0, savings results - 0 views

  • The Department of Energy has just wrapped up a fascinating experiment in Washington State in which it provided both homeowners and their appliances with tools that can sense stress on the power grid. Homeowners who made use of the tools saved money—approximately 10 percent on their electric bills—and the grid was more stable, too.

This Changes Everything: Capitalism vs the Climate review - Naomi Klein's powerful and ... - 0 views

  • Much of this book is concerned with showing that powerful and well-financed rightwing thinktanks and lobby groups lie behind the denial of climate change in recent years.
  • Klein interprets the marginalisation of climate change in the political process as the result of the machinations of corporate elites. These elites “understand the real significance of climate change better than most of the ‘warmists’ in the political centre, the ones who are still insisting that the response can be gradual and painless and that we don’t need to go to war with anybody… The deniers get plenty of the details wrong… But when it comes to the scope and depth of change required to avert catastrophe, they are right on the money.”
  • Klein is a brave and passionate writer who always deserves to be heard, and this is a powerful and urgent book that anyone who cares about climate change will want to read. Yet it is hard to resist the conclusion that she shrinks from facing the true scale of the problem. When I read The Shock Doctrine (Guardian review headline: “The end of the world as we know it”), I was unconvinced that corporate and political elites understood what they were doing in promoting the wildly leveraged capitalism of that time, which was already beginning to implode. The idea that corporate elites are in charge of the world is even less convincing today. The neoliberal order has recovered, and in some countries even achieved a spurious kind of stability, but only at the cost of worsening global conflicts.

  • Another problem with pinning all the blame for climate crisis on corporate elites is that humanly caused environmental destruction long predates the rise of capitalism.
  • Though she identifies the prevailing type of capitalism as the culprit in the climate crisis, Klein doesn’t outline anything like an alternative economic system, preferring instead to focus on particular local struggles against environmental damage and exploitation. In many ways this makes sense, but in a global environment of intensifying scarcities, giving priority to local needs is unlikely to be a recipe for harmony. Whether in the Congo in the 1960s or Iraq at the present time, internecine conflicts – exploited and aggravated by the geopolitical stratagems of great powers – have led to a condition of endemic war.
  • Throughout This Changes Everything, Klein describes the climate crisis as a confrontation between capitalism and the planet. It would be more accurate to describe the crisis as a clash between the expanding demands of humankind and a finite world, but however the conflict is framed there can be no doubt who the winner will be. The Earth is vastly older and stronger than the human animal.

Smart Grid: Top Ten Trends - 1 views

  • A few of Pike Research’s smart grid industry predictions include the following:- Security will become the top smart grid concern- Distribution Automation will rival AMI as the most visible smart grid application- The “Bakersfield Effect” will continue, but some consumers will actually LIKE the smart grid- Smart meter and AMI focus will shift toward Europe and China- The “Year of the HAN” will not arrive… yet- The Demand Response business transformation will accelerate- The ARRA smart grid “stimulus” will finally have a positive impact- The standards “horse” will begin to catch the deployment “cart”- Data management will be the next bottleneck to smart grid benefits- Existing data and telecom vendors will get serious about the smart grid
