Jerome a Paris has an excellent (and long) article at TOD about the economics of wind power - The cost of wind, the price of wind, the value of wind. I'd like to try to clear some of the confusion that surrounds the economics of wind power, as it is often fed and used by the opponents of wind to dismiss it. As I noted recently, even the basic economics of energy markets are often wilfully misunderstood by commentators, so it's worth going in more detail through concepts like levelised cost and marginal cost, and identify how different electricity producers have different impacts on electricity (market) prices (which may or may not be reflected in retail prices) and have different externalities. Value for society of a generation source may also include other items that are harder to acount in purely monetary terms (and/or whose very value may be disputed), such as the long term risk of depletion of the fuel, or energy security issues, such as dependency on unstable and/or unfriendly foreign countries or vulnerable infrastructure.

1. What kinds of sorbitan esters are there? They are distinguished according to different fatty acids. A lot of people do not know what sorbitan esters are. Sorbitan ester are emulsifiers that can be used in many industries, especially in food. Chemical components of sorbitan esters are dehydrated sorbitol fatty acid esters, which are mixtures of esters compounds, formed by the reaction of sorbitols and its mono-anhydride and dianhydride with fatty acids. Sorbitan esters have different forms, for example, amber viscous liquid, yellowish waxy solid, amber viscous oily liquid and yellow oily liquid. Sorbitan esters are common W/O emulsifiers with an HLB values between 1.8 and 8.6, a hydroxyl values between 60 and 360 and a saponification values between 140 and 188. They are not insoluble in water, but soluble in ethanol and easily hydrolyzed by acids, bases and enzymes. Depending on different fatty acids, sorbitan esters can be divided into several varieties, such as sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan tristearate, sorbitan monooleate, sorbitan trioleate. Now let's focus on discussing sorbitan monooleate. 2. Sorbitan monooleate and polysorbate 80 emulsifiers are used differently in the food industry. (1) Polysorbate 80 is a kind of polyoxyethylene sorbitan fatty acid esters, which is an amber viscous oily liquid.

Next100 has a post on "demand response" - managing customer demand in peak periods to reduce the need for costly, rarely used generation capacity and to allow greater penetration of renewable energy sources - The Invisible Energy Resource. The media rush to highlight every major new renewable power project, but another clean energy resource gets far less attention, even though it's flexible, abundant, relatively inexpensive and valued overall at billions of dollars. According to a recent report by the North American Electric Reliability Council (NERC), this unheralded resource is equal to 29,000 megawatts of capacity during periods of peak summer demand--as much as all U.S. wind, solar, geothermal, and biomass power combined.

The value consumers place on goods and services often is a matter of simple economics. When demand is high and supply low, relative worth heads north. This fundamental truth from our friend Adam Smith couldn't be more relevant to the car business these days. Visit any dealership and ask how many thousands of dollars in incentives are available on trucks and SUVs collecting dust on the lot. On the flip side, the Prius hybrid's massive worldwide appeal is not only a sign of our energy-afflicted times but proof of what happens when there are more shoppers than cars.
