Wind Power: The Truth
Wind Power Facts video is packed with interesting and current facts about wind power, and is a great learning resource about wind energy.

             List of facts included in the Wind Power Facts video 


In order to protect the animals, we must protect the environment as well. If the environment were to crumble then nature will fall as well. The Polar Ice caps are melting rapidly, causing the weather to become corrupt. The main reason is our release of Carbon Dioxide. Burning coal, gasoline, oil are the cause behind these excess gas. If we were not to burn these fossil fuels, the world environment will improve immensely. 

In Kyuushu University, they invented and introduced a new, effective wind power addition called, "Kaze Lens", which means "Wind Lens". It is now internationally tested. I interviewed the president of the project, Yuji Ohya, who is a professor and environmentalist.

Q : Are you able to attach these new Wind Lens to current wind power fans? 

Ohya : We can. But, foreign wind power blades are slightly different. If we were to attach the Wind Lens, it will slightly loose power from the rate it creates energy. but still improves 1.6-2 times higher energy production. In Japan, the Lens will created three times more energy verses non-lensed wind power plants.  

Q : Is it safe for flying birds and surrounding nature?

Ohya : The Lens is quiet large, birds are most likely to avoid it. We have many wind power plants with Wind Lenses attached, but there hasn't been a case of bird strike for 6 years.

Already it was installed, Dozens in Japan,  UK, Canada WEICAN (National Canada wind Institute), China. 
Next year install in Thailand.

Global energy issues and demands for CO2 reduction have further attracted interests in development of new energies. As drastic reviews are on-going on the safety understanding and the next scenarios of the nuclear power generation, safe natural energies such as solar, geothermal, hydro, tidal as well as wind energies should be seriously challenged for each effective and practical utilization.Japan is sometimes mentioned with its small land and lack of natural resources, but the total area of territorial waters and exclusive economic zone (EEZ) is the 6th largest in the world. Kyushu University is currently challenging for development of new energies including one with novel high power efficiency Wind-lens turbines. The challenge is on-going with an outlook on realising High Density Off-Shore Electric Power Generation Farm utilizing very wide Japanese EEZ. 


Here, Integrated Off-Shore Electric Power Generation Farm“ means an off-shore energy farm on floating bodies with combined power generation systems such as wind, solar, tidal, wave, tension power applied to the anchoring wire, etc.

Stage I

The first step has started towards Hybrid Off-Shore Electric Power Generation Farm with system development for off-shore wind power generation using 3kW Wind-lens turbines that have been developed by Wind-lens Research Team of Kyushu University. The plan in 2011 includes launching the floating body of ~18m diagonal in the east part of Hakata bay with two 3kW Wind-lens turbines. 

For preparation, in March 2011, a large wave tank in Research Institute for Applied Mechanics, Kyushu University, was used for the theoretically- scaled model experiments for investigating motions of the float responding against high waves and strong winds. 

During the test experiments in the wave tank, a harsh conditions was generated corresponding to a wave height of 6m and a wind speed of 30m in the natural condition, and the stable behaviour of the floating body against the condition was confirmed.


StageII (plan)

In the next stage for constructing the floating body in Hakata Bay, an Integrated Off-shore Floating Energy Farm (1-2MW) is being planned with connecting 100m size large floating bodies in the off-shore area in Japan. This farm will accommodate medium size (300kW at a wind speed of 12m/s) Wind-lens turbines according to the current plan.A prototype of the medium 100kW Wind-lens turbine can be seen in Kyushu University Ito Campas.


Stage III (plan)

Challenges for further scaling-up in future of Wind-lens turbine (1MW class) and Off-shore Energy Farm are on-going through researches on improving structural materials, supporting structure of the wind-lens, etc.

NY Leaders Can Reduce Cost of Harnessing State’s World-Class Offshore Wind. Direct State Actions Combined with Industry Advances Could Cut Project Costs in Half 

03-11-2015 // Miles Grant



The climate changes the planet is currently undergoing, and the threats posed by greenhouse gases, all interlink with the entire planet's ecosystems which have been carefully balanced for millennia. Since the industrial age, this has changed, and the way we now exploit the Earth's resources affect everything in the chain. Forests, wetlands and oceans have absorbed carbon forever - now with mining, eradicating forests for agriculture etc., these gasses are building in the atmosphere and can endure there for a century permitting ever-increasing rises in temperature, which in turn leads to ice-melt and rising sea-levels. While world governments and individuals confront how to reduce energy levels which result in CO2 emissions, the ecosystems also need to be considered. Deforestation alone can add more of a threat to global warming than all the cars on the planet's roads. It's unfortunately a very complex subject, difficult to summarize in a few short paragraphs. It has been necessary for us, then, to give more attention to each of the major ecosystem issues where we can learn what went wrong, and what must be done to mitigate a looming crisis.   Read more



          ◆CARBON DIOXIDE   CO2◆

With CO2 now being declared a danger to human health by the US EPA , its significant threat as a greenhouse gas is given added importance as the leading cause of climate change and rising temperatures on the planet. The concentration of carbon dioxide in the atmosphere caused by the combustion of fossil fuels (coal, gas, & oil) has increased by around 40% since the beginning of the Industrial Revolution. As the level increases in the atmosphere and the oceans, we're getting further away from the solution. How much we can safely emit is in conflict with how very much more we produce - especially in North America. It's a problem that will be with us, and we need to understand why it's planet Earth's greatest threat. The planet will survive somehow, but will humanity? 


 ●●●●●●●●●Coal ●●●●●●○○○

According to EPA, American coal plants produce 386,000 tons of hazardous air pollutants per year. Coal-fired electric power generation emits around 2,000 pounds of CO2 for every megawatt-hour generated. The toxins they release, hazardous chemicals that can lead to disease, brain damage and premature death, affect every part of the human body. Arsenic, chromium and nickel cause cancer; lead damages the nervous system; acid gases irritate the nose and throat; dioxins affect the reproductive endocrine and immune systems; and volatile organic compounds weaken lungs and eyes. link The global dominance of industrial interests dependant on cheap energy sourced from coal means that climate change is inevitable. Unfortunately, there is enough cheap coal around to power ever-higher emissions for at least another century. The world will inevitably become much warmer. 

Can We Replace U.S. Coal Power with Clean Energy?

Coal electric power generation is under enormous regulatory pressure to substantially reduce stack emissions.  The EPA requires huge reductions in most coal plant emissions including carbon dioxide (CO2).  As a result, most new coal power plant projects are being cancelled and many existing coal plants are expected to shutdown prematurely. 

Coal accounts for 42% of total U.S. net power generation today.  A very feasible strategy to quickly and substantially reducing U.S. CO2 emissions is replacing most or all of the coal consumed within the Electric Power Sector.  The Power Sector consumes the vast majority of U.S. coal in about 600 power plants across the U.S.  Replacing coal power with clean energy or clean power also provides an excellent synergy for reducing future Transportation Sector CO2 emissions.   For future EV’s to eventually become ‘zero emission vehicles’ (ZEV’s) requires substantial reductions in fossil fuels used to generate U.S. electric power.  Replacing all coal with clean power facilitates the actual development of future ZEV fleets.

Officials: Unsafe levels of arsenic from Duke Energy coal ash dump pouring into rive


In this Wednesday, Feb. 5, 2014, photo, Jenny Edwards, program manager for Rockingham County with the Dan River Basin Association, scoops coal ash from the banks of the river as state and federal environmental officials continued their investigations of a spill in Eden, N.C. Duke Energy estimated that up to 82,000 tons of ash was released from a break in a 48-inch storm water pipe at the Dan River Power Plant.  GERRY BROOME, AP

●●●●●●●●●O I L Off Shore Drilling●●●●●●●●●●
Much of the world runs on oil, most from land, but some from ocean drilling.  Given the locations of the remaining oil, the costs have been far higher, though technology has made it more accessible. Canada's tar sands are becoming a serious issue, and with the Arctic ice melting, oil companies are racing to drill there with serious environmental issues involved. 
The Earth has been accumulating oil and natural gas for about a billion years or so. Humans have been drilling and burning crude and gas in significant amounts for only the last 156 years, since the 1859 birth of the oil industry in Pennsylvania. Since 1980, the world has burned nearly 40 trillion gallons. Since 1980, the amount found, but not yet produced, has more than doubled. The world's proven reserves are now 71 trillion gallons, up from 683 billion barrels in 1980. That's part of what worries climate scientists so much. Burning the oil and gas that we've already found, never mind what we haven't yet, will lead to dangerous and possibly catastrophic changes in the earth's climate, they say. 

       Shell's profit comes at our expense



There are currently about 437 commercial nuclear power reactors operating in 31 countries around the world, producing 13.5% of the world’s energy - 372,000MW. Sixteen countries depend on nuclear power for at least a quarter of their electricity.  France gets around three quarters of its power from nuclear energy - the USA  almost one fifth.  link  Safety, massive cost overruns and building delays are major problems for any future projects which would require huge government subsidies. No nuclear reactor has ever been built anywhere in the world without substantial government subsidy, and no reactor ever will be built without substantial government funding in future. Also private investors are not enamoured by nuclear power because construction risks are too high (with cost overruns and substantial delays all but guaranteed), and the political risks (with governments constantly changing their mind about levels of support) even higher. [The 104 nuclear reactors currently operating in the United States use between 25,000 and 27,500 tons of uranium oxide per year.] Thorium is considered a safer and cheaper alternative.

○○○○○○○○○Natural Gas○○○○○○○○○○     
Natural gas is a combustible gaseous fossil fuel. While contributing less CO2 to the atmosphere than other fuels, it is still a serious greenhouse gas. (The average U.S. natural gas plant emits 800 to 850 lbs of CO2 per megawattt.whereas coal plants emit an average 1,768 llbs of CO2 per megawatt.)
Transporting natural gas by tanker can involve similar risks to transporting oil by sea. With its cost receding in recent years, more attention is being paid to its commercial uses. The main products of the combustion of natural gas are CO2 and water vapor. But the problem of "fracking" has serious.


Methane (CH4) is by far the most important non-CO2 greenhouse gas - a relatively potent greenhouse gas responsible for nearly as much global warming as all other non-CO2 greenhouse gases put together. Methane is created naturally near the Earth's surface by microorganisms by the process of methanogenesis and carried into the stratosphere by rising air in the tropics. It is important because of the potential harm it has for global warming, but it also has value as an energy source. There is much less methane in the atmosphere than CO2: about 1800 parts per billion (ppb), compared with an estimated 390 parts per million of CO2. However its potential for global warming has been estimated at 25 times greater than CO2 . While CO2 emissions are estimated to contribute 75% to global warming effects, methane is a distant second at 15%. And as with other greenhouse gases, methane levels have been rising; they are now more than twice what they were in the early 1800s when methane levels were closer to 715ppb. Half of current emissions is human-related which includes landfills, agriculture and coal mining.


△▽△▽△▽ETHANOL and BIOFUELS△▽△▽△▽△▽△▽

Since the early 2000's, ethanol and other biofuels have been seen as a solution to our dependence on oil. This has proven not simply a misguided course, but brought with it unintended consequences to the world's food supply. It has been a distraction from focusing on clean energy sources as a means of powering our transport needs in the future. While corn ethanol was originally believed to be a promising alternative to petroleum, it has been largely discredited on several counts. Now we need to determine if, and which, biofuels could be part of the solution, and to what degree, if any, they would reduce greenhouse gases.
