Filed under Wind and Solar

Switching from conventional sources of electricity like coal and natural gas to renewables like wind and solar, our elected leaders tell us, will reduce pollution, advance renewable technology and spark a green jobs revolution. Is renewable energy really a green pathway to a brighter economic future? Or is it nothing more than a heavily subsidized impossible dream? To learn more, we spoke with Cal State Fullerton economist Robert Michaels and Mark Tholke, an executive at enXco. Approximately 6.5 minutes. Produced by Paul Feine and Alex Manning.

We are currently seeking investors, and manufacturing companies to license, purchase patent rights, or enter into a royalty agreement for this, and our other inventions from “DW”- the inventors of this innovative new product. When you think about it, almost every great advance in medicine, art, engineering, politics, religion, design, and RULES FOR THINKING, in general, has occured when people challenged the previous rules of thought and tried a new approach. Here’s a unique inexpensive use for bamboo to make a vertical windmill. This is a new “spin” for bamboo! Let’s get this inexpensive vertical wind turbine product producing power in India, Africa, Asia, and other tropical bamboo growth areas globally. (pp) The power output can be adjusted to suit the given resource of wind currents from any direction. We have a solar photovoltaic componet add-on at high speed rotation as a hybrid energy additive for storage or kick laucnhing the “first motions”! (rotational inertia) It is said that fully 70% of the economy in areas of India come from bamboo products. Here’s one that produces energy & money long after it’s built. In addition, solar cells have been shown to last 25 years or more, so the additional high rpm solar umbrella on top, is a must! With this VAWT, ALL WINDS ARE ACCEPTED FROM ALL DIRECTIONS! (no tail fin needed) Also, this VAWT has easy, low to the ground maintenance, –and cheap materials & as always, it’s “cost per watt” to the bottem $$$$$$- line. To capture a

Solar Power in the US Southwest

Many power plants burn coal or natural gas to make steam and generate electricity. But power also can come from a cleaner, more renewable source — concentrated solar power. From sunny Las Vegas, Nevada, Shelley Schlender reports

Wind turbines and health problems

Windmills may be an environmentally friendly alternative energy source but they also cause debilitating health problems, say people who live near them. Wind turbines are popping up in rural communities around the world, including Canada, in the hope that they will reduce reliance on coal and other sources for power. Currently, there are about 1500 turbines across Canada and there are plans to build another 1000 to 1500 in the next year. But some residents who live near wind farms complain the turbines cause a number of adverse health effects, such as crippling headaches, nose bleeds and a constant ringing in the ears. Helen and Bill Fraser initially supported the nearby wind farm in Melancthon, Ont. One turbine sat close to the Fraser’s kitchen window. “We thought, more green energy, this is great,” Helen told CTV News.However, Helen says she developed headaches, body aches and she had trouble sleeping. The dog began wetting the floor at night. www.windaction.org

Solar Power – Cutting Your Energy Bills and Saving The Environment

The concept of solar generated energy has the kind of truths behind it that would make the vast majority of advertising executives salivate.

Firstly, the environmental considerations of using solar energy are huge. With fossil fuels, such as coal and oil, set to run out at some point; there has been a renewed focus in finding sustainable and renewable energy. Solar power has come to the forefront of such discussions as a viable alternative to the old ‘digging stuff out of the ground and burning it’ way of generating energy.

The effect this ability for renewable energy which takes nothing from the earth itself is huge. While solar power will never be able to meet all of the Earth’s energy demands, it should certainly be able to sate a large portion of the populace. By switching to such renewable energy that capitalizes on a natural resource, the environmental impact would be significant.

Secondly – and this is where the aforementioned advertising executive would really become excited – solar power could save the average member of the population money. By having solar panels installed, people could save as much as 30% on their usual electricity and heating bills.

With every year that passes, the general populace becomes more concerned about their own impact on the environment and their own dependence on fossil fuels. As time passes, these people with particular concerns are looking at utilizing other forms of energy. Once upon a time, seeing solar panels on the roof of a normal home would have been alarmingly unusual, but it is now fast approaching the norm. The average household is now capable of saving the environment and saving money – what are you waiting for?

How Reliable Is Solar Power?

With solar power being flaunted as one of the realistic alternatives to the burning of fossil fuels, it is only natural that enlightened thoughts are turning to the reliability of the energy it can create. After all, the sun is an intermittent energy source. It does not always shine, with most countries experiencing cloud cover for large portions of the year. There is also the issue that the sun is only available for, at most, 12 hours out of every 24. Could the world’s energy demands really be sustained from what seems like such an unreliable heat source?

The answer is probably no, which is why solar energy is only being spoken of as one of the options for continued energy production. However, solar energy is one of the most viable of the options mentioned, even if it could not meet the entire world’s demands for energy by itself.

The reason for this is simple; the sun is a constant. The sun will continue to shine for as long as there is life on earth; by the time the sun begins to dim, the earth as we know it will begin to die. Unlike the expendable resources of coal and oil, this makes the sun very dependable – it will be here for as long as the world will.

The sun is also relatively easy to ‘tap’ into, as it shines directly onto earth and needs no human interaction for it to work to its full potential. While manufacturing solar panels can be expensive, they are relatively hassle free once created, and the only engineering they require to function is to be pointed as directly as possible toward the sun. This is certainly more viable than having to dig into the earth for coal, or send rigs out to sea to collect oil.

Solar power is, therefore, a reliable energy source. How effective it is is a matter of debate, but one should largely assume that much – if not all – of the world’s demand for energy can be satisfied by our most powerful celestial friend.
