"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."

A collaboration in Germany is about to explore whether a sizable distributed generation project can supplant centralized power plants. For this project - called SchwarmStrom - 100,000 mini gas-fired generators will provide heat and power in German homes and businesses, with a combined output of 2000 MW!

The International Copper Association (ICA) is the leading authority on the fundamentals of future copper demand and substitution. ICA’s portfolio of material demand and substitution work covers global studies, surveys and detailed data sets. Full studies and data sets are used by ICA and its members for market development purposes, and select information is available to market commentators.

Appearing on PRI’s The Takeaway with John Hockenberry, Golden was asked how he would advise Congress and the upcoming Obama administration on the proposed U.S. multi-billion dollar auto industry bailout. He responded by unequivocally advocating the avoidance of “any further investments into the old combustion engine model” arguing that the country needs to quickly move past hybrids by leap-frogging “to an all-electric platform.”

It turns out that with peak oil here already, we are soon not going to have the cheap energy to maintain global trade or food production on today's scale. And renewable energy is not ready to step in as enough of a substitute, when the oil market will soon be handing us an unmanageable, exacerbated shortage

For this special report, PM crunched the numbers on the actual costs and performance of each major alternative fuel. Before we can debate national energy policy--or even decide which petroleum substitutes might make sense for our personal vehicles--we need to know how these things stack up in the real world.

shared by Colin Bennett on 09 Nov 09 - Cached

Graphene is an extremely low density material, almost an atomic-scale chicken wire made of carbon atoms and their bonds. It has been the focus of much research because of its exceptional electrical, mechanical and optical properties. It holds great promise in renewable energies. Among the so far underutilized advantages Graphene offers are that it is fifty times stronger than steel, and it has five times the conductivity of copper, with only one quarter of the density.

Scottish Researchers Revolutionize Wind Turbine Engineering With Minor Tweak - 1 views

The researchers there have developed a system that is simpler to assemble and manufacture, and laid out their suggestion in a paper (pdf) presented at the 2008 European Wind Energy Conference. Till now; the blades of wind turbines have been connected to a generator via a gearbox. Their technology substituted a “C” shaped core generator (initially in a 20 kW prototype) to test to see if by changing the mechanical structure of the generator they could still maintain rigidity and structural integrity while cutting the weight by more than half. The design is simply a novel arrangement of the electromagnetically active components: the magnets, steel and copper inside the generator and the copper coils.
