Green, Solar & Wind Power

Green Generators Power plants of the future, meant to produce cleaner energy, likely will combine two or more alternative energy technologies to make electricity more efficiently, a Rutgers University engineer believes.

Scotland is building Europe’s largest wind farm which will power 200 000 homes The world’s biggest wind farm will be located 12 miles off the coast between Margate in East Kent and Clacton in Essex. It will consist of 341 turbines spread over 90 square miles. The UK’ fifth of pwer from renewable sources, mainly wind, by 2020. In the future we may see buildings with integrated turbines which may generate 20% of their own power, power used for shipping and floating wind farms.

Solar Panel Such combinations should reduce energy production costs because hybrid systems would share infrastructure such as grid interconnection and maintenance expenses. At the same time, energy such as heat wasted by one system could be used by the other, said Dr. Mike Muller, a professor of mechanical and aerospace engineering at Rutgers.

Despite Britain enjoying 40% of Europe's wind energy; it is way behind Denmark, which generates 18% of its total electricity from wind. It is essential that we use renewable energy sources now and in the future to ward off the catastrophic effects of global warming. there is no doubt that wind power will increase its share of the fuel mix in the years to come.

Epa Greenpower Muller told about 20 policymakers, government workers and reporters at a briefing on fuel technology on Tuesday that a variety of energy systems, mostly small in scale compared with today's typical power plant, will be used for different energy needs. Smaller-scale systems will enable facilities such as a campus or even a large building to replace part of its energy supply with a hybrid system.

Solar roofing shingles are shingles that look very much like ordinary shingles but they allow your roof to generate solar electric power. Solar roofing shingles install just like traditional asphalt singles. Once you hook them to your home's electrical system, you're generating solar power that can drastically reduce your electricity bill.

Wind Energy Many technologies are being researched at the Rutgers Center for Advanced Energy Systems, a collaboration of university research programs.

The gentle curves of the Spiral Solar Wind Chime will come alive with the power of the sun, chiming softly to help your day along.

Solar "We are interested in buying green power. The state is interested in buying green power, so there's a market for it," Muller said.

Drive watches use the simplest, yet most technically advanced power generating and storage system in the Watch Manufacturing Industry. A Solar conversion panel and energy cell are the power provider for these Quartz Watches. Drive's ability to use light from any source to generate electrical power means that the supply is limitless and free. The absence of any added complex power generating machinery that would require additional upkeep is another big advantage.

Nuclear Power Still, cost remains a key factor, and some new energy technologies have significant startup expenses.

Greenpower Inc Muller noted that photovoltaic solar systems will remain relatively expensive until they are mass-produced. One such system at Johnson & Johnson's Cordis Corp. facility in Warren, which makes devices used in heart surgery, is not economical, despite government incentives such as tax credits and accelerated depreciation, he said.

Solar Electricity Another longstanding problem is that electricity production remains inefficient, with much of the fuel used to produce electricity wasted.

Power Greene The efficiency level for power distributed over an electric grid rose from 5 percent in 1900 to 32 percent in the 1960s, with no improvement since. Some hybrid systems might eventually reach 70 percent efficiency, Mueller said.

Green Electric Along with solar and wind power systems, technologies being studied include fuel cells, power derived from waves and undersea currents, burning of wood waste and waste gases from landfills, and even "clean coal" systems that remove the worst pollutants before the coal is burned.

Am Greenpower Among the hybrid systems already in use are one combining solar cells, propane and a battery system to run an Arizona marina, and one in tiny Wales, Alaska, that uses wind turbines backed up by a diesel engine.

Renewable Electricity "If everyone ... starts covering 5 percent of their building with aggregate systems like this, we will make a dent" in future needs for cleaner energy, Muller said.

Green Company Muller focused on energy systems for stationary uses, such as supplying businesses and homes. But he noted that President Bush's call last month for $1.2 billion in new research spending on hydrogen-powered fuel cells for cars should accelerate development. Fuel cells combine hydrogen and oxygen to make electricity.

Led Greenpower One roadblock is finding a way to store large amounts of hydrogen in a lightweight form at normal temperatures and pressures, something not possible yet. Researchers at Rutgers and elsewhere are working on one possibility, carbon "nanotubes," or microscopic, whisker-shaped carbon structures that keep hydrogen molecules attached.

Alternative Energy "Many of us will be riding in a hydrogen-fueled car before long," Muller predicted.
