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.

I've got another guest post from Neil Howes up at TOD, this one proposing a rough plan for North AMerica to obtain 50% of its power from wind by 2030 - A North American Wind Energy Scenario. Would a "50% of electricity generated by wind scenario" work in North America by 2030? In this post, I make a rough cut estimate of what might be required to make such a transition in about 20 years time. Most proposals that are being made rely on a very big increase in carbon free energy, both to charge electric vehicles (EV's) and to replace oil and natural gas (NG) presently used for hot water and space heating. In this post, I lay out a path by which 50% of North American energy might come from wind by 2030, including replacement of a large share of oil and natural gas use by electricity. ... High quality wind resources (wind speeds greater than 6.9m/sec) in the US are estimated to be >5,500GWa, about x10 all of N America's present electricity production of 550GWa. Canada's potential appears to be similar or greater than the US, while Mexico's wind resources are more limited (these figures do not include deep offshore resources that could be harnessed by floating wind turbines or higher altitude wind resources that could potentially be harnessed by airborne wind turbines).

T. Boone Pickens has called off his massive wind farm project. As he put it, he didn't realize how many problems he would have with transmission.

Ezra Drissman of GreenCareersGuide gives suggestions on how to get a good green job by becoming an energy consultant.

The green industry is one of the hottest industries to work in these days. But contrary to the antiquated perception of green, working in the industry doesn't really mean working in the fields.

The number of wind turbines is set to quadruple over the next decade under government plans to force through wind farm planning applications. Ministers have put wind power at the heart of a Renewable Energy Strategy, which is due to be released on Wednesday. It will outline how Britain is to meet its target of a 34 per cent cut in CO2 emissions by 2020.

For some people, eco-tourism means going to the areas where the environment is still fairly untouched and pristine. To others it has a much broader scope than that, and means that you do everything you can, to make the trip you are taking eco-conscious, including how you get there and what you do once you arrive.

They say people in glass homes shouldn't throw stones. Well, this is one glass home you're not likely to find a squabbling pair in. In 1984, Buddhist monks in Thailand began gathering bottles to decorate their shelters.

One of the biggest advantages of a universal smart grid would be its ability to create smart energy consumers. Because the smart grid would actually be able to define and identify individual energy wasters and then charge them accordingly, there would be a huge economic incentive for more careful consumption.

A solar water heater can save around $450 in a year and can keep tons of CO2 emissions out of the air. If that is multiplied by 80 millions houses in the U.S., just imagine how clean we can keep our environment.

Some general knowledge of plants, how they grow and breeding techniques is obviously necessary. Other skills that could be useful would be some basic genetics and hybrid techniques.

Smart grid technology can affect energy pricing in two ways: raising the rates for high-demand peak periods and lowering it during off-peak times.

So, you have decided to begin using an alternate energy source. That is great. But, which one is the right one for you?

Green collar jobs are truly in the beginning stages. Many times we read articles on how there is no real definition to a green career. In many ways, they are right but completely miss the point.
