There is little doubt that global CO2 emissions have to be greatly reduced if we are to halt global warming. Wind energy produces more watts per euro invested than any other type of renewable energy. Admittedly if there is no wind you will not be generating...BUT...when there is wind (above 3.2 m per second) you will be generating 24/7, day or night. Emissions are virtually nil.

The Chicago lakefront provides the highest annual wind speeds of any region in the Chicago area. Overall the wind resource in Chicago is moderate: it is better than the resource found in many states, but not as good as states such as California, Texas, and the Dakotas.

The sun's radiation heats different parts of the earth at different rates-most notably during the day and night, but also when different surfaces (for example, water and land) absorb or reflect at different rates. Hot air rises, reducing the atmospheric pressure at the earth's surface, and cooler air is drawn in to replace it. Air has mass, and when it is in motion, it contains the energy of that motion - "kinetic energy.

Wind energy comes from turbines mounted on tall towers. Wind is now the fastest-growing renewable energy source in the world—and it's 100 percent pollution free.

Yes. If biomass is cultivated and harvested in a way that allows regrowth without depleting nutrient and water resources, it is a renewable resource that can be used to generate energy on demand, with little net additional contributions to global "greenhouse gas" emissions. Burning biomass efficiently results in little or no net emission of carbon dioxide to the atmosphere, since the bioenergy crop plants actually took up an equal amount of carbon dioxide from the air when they grew.

Creatine kinase can convert phosphocreatine into creatine, meanwhile phosphorylating ADP to make ATP. However, this process provides energy for only about four seconds of physical exertion.

Yes. It is possible to meet all of your energy needs through a renewable energy source. You will need to determine your usage profile, load profile and site conditions which will dictate how much solar photovoltaic cell and/or wind will be necessary to supply your alternative energy source power.

Here are answers to frequently asked questions about wind. Scroll through the list, or use the search functions to find the answer you're looking for.

A. Ultimately all of our energy comes from the sun. Periodic exposure to the full spectrum of natural light is necessary for optimal gene expression. Think of the varied pigments found in plant foods to be frozen energy, even information of the highest order. Think of filling up your stomach three and four times per day with green vegetables as a starter. Find balance in your life. Respond positively to stress. Drink water, boost fiber, and engage in moderate exercise.

The source of the energy for all convective vortices including: dust devils, waterspouts, tornadoes and hurricanes is the buoyancy of the air rising in the eyewall of the vortex. In the case of dust devils, where there is no condensation, the air near the ground can be 10 to 20?C warmer than the ambient air at the 10 m level and the rising air can be approximately 5?C warmer than the air through which it rises.

The economics of generating electricity from the wind have improved greatly over the last ten years. The price of electricity generated by wind turbines is comparable to that of any new build gas power station and by and large cheaper than any new coal station fitted with clean-coal technology.

One of the most helpful things you can do is to help us win the debate on wind energy. Respond to letters in local and national papers, write to the local planning authority at the council, write to councilors themselves, participate in radio phone-in programmes and wherever else the opportunity arises. There are innumerable independent national polls that show well over three-quarters of the population support wind energy ??" please don't be one of the silent majority and support wind.

Opinion surveys regularly show that just over eight out of 10 people (80%) are in favor of wind energy, and less than one in ten (around 5%) is against it. The rest are undecided. Public opinion in support of wind power tends to become even more strongly in favor once the wind turbines are installed and operating, a finding from several surveys carried out in the UK and in Spain.

Local opposition to proposed wind farms usually arises because some people perceive that the development will spoil the view that they are used to. It is true that a large wind farm can be a significant change, but while some people express concern about the effect wind turbines have on the beauty of our landscape, others see them as elegant and beautiful, or symbols of a better, less polluted future.

A modern wind turbine produces electricity 80-85% of the time, but it generates different outputs dependent on wind speed. Over the course of the year, it will generate about 30% of the theoretical maximum output. This is known as its load factor. The load factor of conventional coal and gas fired power stations is around 40%. A modern wind turbine will generate enough to meet the electricity demands of more than a thousand homes over the course of a year.

A wind energy system can provide a cushion against electric power price increases. Wind energy systems help reduce U.S. dependence on fossil fuels; and they are nonpolluting. If you live in a remote location, a small wind energy system could help you avoid the high costs of having utility power lines extended to your site.

a renewable source, wind energy has the following generic advantages: it never runs out and does not contaminate the atmosphere.

From an environmental perspective, wind energy is one of the best new generation options immediately available in New Zealand. Fossil fuel alternatives emit greenhouse gases, and other renewable options have smaller capacities, longer lead times, or are more expensive. Wind farms are a sustainable and environmentally responsible alternative to using fossil fuels for electricity generation.

Wind power generation is unlikely to ever totally replace other forms of generation such as fossil fuel or hydro power stations. This is because the wind does not always blow strongly enough and because many wind turbines would be needed to generate enough electricity. New Zealand has consistently strong wind conditions compared with most other countries, which makes wind power generation much more reliable here.

In Delaware, and along the densely populated east coast, there is scarce suitable land for onshore wind parks. Located more than six miles from land as proposed by Bluewater Wind, the Delaware wind park, when visible at all, will appear very small on the horizon. Connecting offshore turbines to the power grid avoids construction of expensive high voltage overland transmission lines.

A turbine and switchgear are mounted at the top of each tower in a casing called a nacelle, and blades are attached to the turbine. The turbines use moving air to produce power by transferring the wind’s momentum to the rotor blades and localizing that energy in a single rotating shaft. The larger turbines rotate at about 15 revolutions per minute.

Utilities must maintain enough power plant capacity to meet expected customer electricity demand at all times, plus an additional reserve margin. All other things being equal, utilities generally prefer plants that can generate as needed (that is, conventional plants) to plants that cannot (such as wind plants).

Wind energy could supply about 20% of the nation's electricity, according to Battelle Pacific Northwest Laboratory, a federal research lab. Wind energy resources useful for generating electricity can be found in nearly every state. U.S. wind resources are even greater, however. North Dakota alone is theoretically capable (if there were enough transmission capacity) of producing enough wind-generated power to meet more than fourth of U.S. electricity demand.

Fossil fuels such as coal and natural gas are the source of most energy in homes. Natural gas can be used to heat water and warm living space. Sometimes electricity is used in place of natural gas for heating. Electricity is used by air conditioners to cool homes. Coal (and increasingly natural gas) is burned in power plants run by utilities to produce electricity used in homes.

Yes, hydrogen is the most abundant element in the universe. We can get it from water, which covers over 75% of the earth. If and when water runs out, we will have much larger problems to deal with.
