Green energy includes natural energetic processes that can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar power, biomass power, tidal power and wave power fall under such a category. Some versions may also include power derived from the incineration of waste.
More controversial is nuclear energy's claim to be green. It is not sustainable, nor renewable[1]. However nuclear waste is a pollutant if released into the biosphere, and there are carbon dioxide and other greenhouse gases generated by the large amount of energy required by transport, mining and pre- and post-production. Hence, nuclear power is rarely included in official green energy schemes[citation needed]. Proponents of Nuclear Power tend to argue that the Nuclear waste is not released into the biosphere during normal operation and that the carbon dioxide emissions per kilowatt hour of generated electricity is comparable to those of other green energy sources, such as wind power[citation needed].
Likewise, medium or large-scale hydroelectric power or sources of air pollution such as burning biomatter or petroleum, consume water and are often excluded from the label 'green energy'[citation needed].
Renewable energy certificates (Green certificates, or green tags) are currently the most convenient way for consumers and businesses to support "green power". Over 35 million homes in Europe, and 1 million in the United States, are purchasing such certificates.
No power source is entirely impact-free. All energy sources require energy and gives rise to some degree of pollution from manufacture of the technology.

World energy resources and consumption
The remaining world energy resources are large, compared to world energy consumption. To make it easier to compare the numbers, this article uses SI units and prefixes and measures energy rate (or power) in watts (W) and amounts of energy in joules (J).
In 2004, the worldwide energy consumption of the human race was 15 TW (= 1.5 x 1013 W) with 86.5% from burning fossil fuels.[1] This is equivalent to 0.5 ZJ (= 5 x 1020 J) per year, although there is at least 10% uncertainty in the world's energy consumption. Not all of the world's economies track their energy consumption with the same rigor, and the exact energy content of a barrel of oil or a ton of coal will vary with quality.
Most of the world energy resources are from the sun's rays hitting earth - some of that energy has been preserved as fossil energy, some is directly or indirectly usable e.g. via wind, hydro or wave power. The term solar constant is the amount of incoming solar electromagnetic radiation per unit area, measured on the outer surface of Earth's atmosphere, in a plane perpendicular to the rays. The solar constant includes all types of solar radiation, not just the visible light. It is measured by satellite to be roughly 1366 watts per square meter, though it fluctuates by about 6.9% during a year - from 1412 W/m2 in early January to 1321 W/m2 in early July, due to the earth's varying distance from the sun, and by a few parts per thousand from day to day. For the whole Earth, with a cross section of 127,400,000 km², the power is 1.740×1017 W, plus or minus 3.5%.
By comparing this contribution by the sun to that contributed by human energy consumption, it can be readily understood that the direct human contribution to earth's heating is a very small fraction: the ratio of 1.5×1013 watts / 1.740×1017 watts is less than 1/10,000th (0.01%). Direct heating of the earth by humans is thus negligible. The earth has been warming recently, however, and mankind's contribution is understandably under close review. Global warming theories that do focus on mankind's contribution point towards the important side-effects of human energy consumption, such as greenhouse gases added to the earth's atmosphere.
The remaining worldwide energy resources are large, with the remaining fossil fuels totaling an estimated 0.4 YJ (1 YJ = 1024J) and the available nuclear fuel such as uranium exceeding 2.5 YJ. Fossil fuel range from 0.6-3 YJ if estimates of reserves of methane clathrates are accurate and become technically extractable. Mostly thanks to the Sun, the world also has a renewable usable energy flux that exceeds 120 PW (8,000 times 2004 total usage), or 3.8 YJ/yr, dwarfing all non-renewable resources. Even that amount is also only a minute amount of the sun's total energy output, due to the small solid angle the earth's outline makes with the sun.

home wind generators Offshore
Offshore wind development zones are generally considered to be ten kilometers or more from land. Offshore wind turbines are less obtrusive than turbines on land, as their apparent size and noise can be mitigated by distance. Because water has less surface roughness than land (especially deeper water), the average wind speed is usually considerably higher over open water. Capacity factors (utilisation rates) are considerably higher than for onshore and near-shore locations which allows offshore turbines to use shorter towers, making them less visible.
In stormy areas with extended shallow continental shelves (such as Denmark), turbines are practical to install — Denmark's wind generation provides about 18% of total electricity production in the country, with many offshore windfarms. Denmark plans to increase wind energy's contribution to as much as half of its electrical supply.
Locations have begun to be developed in the Great Lakes - with one project by Trillium Power approximately 20 km from shore and over 700 MW in size. Ontario, Canada is aggressively pursuing wind power development and has many onshore wind farms and several proposed near-shore locations but presently only one offshore development.
In most cases offshore environment is more expensive than onshore. Offshore towers are generally taller than onshore towers once the submerged height is included, and offshore foundations are more difficult to build and more expensive. Power transmission from offshore turbines is generally through undersea cable, which is more expensive to install than cables on land, and may use high voltage direct current operation if significant distance is to be covered — which then requires yet more equipment. Offshore saltwater environments can also raise maintenance costs by corroding the towers, but fresh-water locations such as the Great Lakes do not. Repairs and maintenance are usually much more difficult, and generally more costly, than on onshore turbines. Offshore saltwater wind turbines are outfitted with extensive corrosion protection measures like coatings and cathodic protection, which may not be required in fresh water locations.
While there is a significant market for small land-based windmills, offshore wind turbines have recently been and will probably continue to be the largest wind turbines in operation, because larger turbines allow for the spread of the high fixed costs involved in offshore operation over a greater quantity of generation, reducing the average cost. For similar reasons, offshore wind farms tend to be quite large—often involving over 100 turbines—as opposed to onshore wind farms which can operate competitively even with much smaller installations.

wind generator
The AIR-X builds upon what made AIR the world's #1 selling small wind turbine with new technology previously found only in mega-watt-class wind turbines.
The turbines smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with the AIR 403 and 303 in high winds. Furthermore, a new series of carbon-reinforced blades with a modified pitch angle further increases power production.
Previous AIR designs required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be adequately absorbed. The AIR-X’s charge controller periodically stops charging, reads the battery voltage, compares it to the voltage setting and if the battery is charged, it completely shuts off all current going to the battery. This function is performed within a few milliseconds. The closer the battery is to reaching its full state of charge, the more often the AIR-X’s circuit repeats this action. When the battery has reached its charged state, the AIR-X will slow to an almost complete stop. Only when the battery has dropped below its voltage set point will it startup and resume charging.
- Simple rooftop installation; no tower necessary
- Carbon Fiber Composite Blades
- Aircraft quality aluminum alloy castings
- Sophisticated internal battery charge regulator
- Maintenance-free - Only two moving parts
- Exclusive Auto-brake-feature that slows the AIR to a silent spin
- High Wind Safe Mode - Automatically slows turbine in potentially damaging winds and reduces noise
- Neighbor Friendly
Rotor Diameter: 46" (1.14 meters)
Weight: 13 lbs (6 kg)
Start up wind speed: 7 mph (3 m/s)
Output: 400 watts at 28 mph (12.5 m/s) Voltage: 12 & 24 VDC (36/48 VDC available soon)
