Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Russ Peterson On Wind Power

Russ Peterson On Wind Power
Public Service Commission Hearing on Delaware's Energy Future

Statement by Governor Russ W. Peterson

November 20, 2007

Madam Chair, Commissioners, and agency representatives, thank you for the opportunity to appear before you today to speak on behalf of Delaware's and our planet's energy future. I have dedicated the better half of my career to protecting our global environment and to the extent that I have been successful, I consider that my legacy. We Delawareans can take pride in the contribution we have made, such as the law to protect Delaware's coastal areas from destructive impacts of heavy industrialization and offshore loading facilities. We fought off the naysayers then and made a commitment to protect our natural heritage for future generations, and have reaped the benefits ever since.

The decisions you four agencies now make in shaping Delaware's energy future will be part of your legacy, and Delaware's legacy. Now is the time for Delaware to face up to the serious threat of global warming by embracing a form of electric generation that does not use the fossil fuels that cause it. You have the opportunity to make Delaware the first state in the nation to generate clean energy from an offshore wind park.

The wind is a free fuel - it transports itself - it doesn't cause global warming - it does not, like the fossil fuels, emit effluents that poison us - it promises electricity at a stable price - it will not be subject to the carbon tax that will very likely and appropriately be applied to fossil fuels - and the technology for using the wind has been well established.

So, why not use it? The large investment in building and installing the wind turbines and transmission lines is high, and will result in a small premium for the electricity produced. The consultant's report estimates about 1.60 per week for an average size house, the price of one half-gallon of gasoline. When a carbon tax is eventually applied to fossil fuels, the premium for wind will be much lower.

You four state agencies earlier blessed the Bluewater Wind proposal and asked Delmarva to negotiate with them. These negotiations have been less than successful. Delmarva Power has wildly exaggerated the premium for wind. She needs to get away from her love affair with fossil fuels and provide some leadership toward reducing the super-serious threat of global warming. I encourage you to do all you can to find common ground here.

A wave of concern about global warming and of resolve to do something about it is now growing and spreading all over the world. Just this past weekend the United Nations Intergovernmental Panel on Climate Change with members from 130 nations reported the results of their latest study. It showed that emissions of greenhouse gasses worldwide was increasing faster than predicted, and making global warming more dangerous than the worst case previously envisioned. The U.N. Secretary General, in releasing the report said, "Climate change is the defining challenge of our age," and called upon the United States to "play a more constructive role." You and I need to take this problem more seriously.

The Nobel Peace Prize Committee showed their concern recently by awarding their Peace Prize to the U.N. panel and to Al Gore for their work in enlightening the world to the threat of climate change. Our own University of Delaware Professor John Byrne is a prominent member of that panel. We can now recognize him as a Nobel Laureate.

More and more countries, states, cities, corporations, churches, and synagogues are becoming involved. The news media have made it a prime subject. The New York Times on Nov. 7 of this year had a twelve-page Special Section on the "Business of Green." Absent significant action by the Bush Administration, state governors are taking over creating regional agreements to cap greenhouse gas emissions. Governor Brian Schweitzer of Montana told a group of Midwestern governors that dealing with global warming was the greatest imperative of this and future generations. "We need to find a sustainable, renewable American supply," he said.

President Harker of University of Delaware is working to establish a new Institute of Alternative Energy to develop renewable energy sources and reduce dependence on fossil fuels. The courts are getting into the action. The Ninth Circuit Court of Appeals just rejected fuel standards established by the Bush Administration, telling them to produce new rules taking into account the value of reducing greenhouse gas emissions.

Clearly a powerful force is building to do something about global warming. We Delawareans have an opportunity to do so by building an offshore wind energy park.

Let's get on with the job.

Wind Power Has Lightest Footprint Carbon And Otherwise

Wind Power Has Lightest Footprint Carbon And Otherwise

A new therapyof the impacts of various energy sources on everyday health and theenvironment finds that wind exceedingly has the smallest engrave on altered,unusually deliberate but renowned aspect: land. Bend powers eco-friendly pursue is so small -a million periodless important than ethanols -that ifall the cars prompted in the AssociatedStates were battery-electric, they possibly will be fueled by wind turbineswhose glaring land pursue, not counting spacing in involving, takes up underneath than 1.2 trustworthy miles, Stanford Instructor eco-friendly engineering professor Establish Jacobson begin. To fuel the enormously make of battery-electric vehicles with celluloseethanol would like an importance of land equivalent to eight Californias- without favoritism a million period advanced land and equivalent to the importance ofland harvested in the U.S. in 2003. Jacobson hit upon the idea of measuring land pursue while audioancestors babble a lot about how noticeably land a certain technology adjoin. Herealized that what they according to the grapevine aimed was the when all's said and done "spacing". Assured technologies desire wind gang to clasp up a lot ofinterruption, like the turbines want be separated. Yet, if you unevenly atthe well land they clasp up, it's not fountain noticeably. For wind infaithful and exceedingly for tidal turbines, the well tough land thatthey clasp up is noticeably different from the spacing. The land involving wind turbines is free for other uses. In Iowa, the No. 2 wind power state in the territory, wind turbines seedling from uncultured areas of farm fields. Maine is building wind farms fluff its reach your zenith ridges. A report uninhibited finishing week by the Parkland Strategy Institute at MichiganStateInstructor not compulsory that if Michigan turned its unusable,industry-damaged brownfields concerning for wind farms, the energy generatedpossibly will power nigh on half of Michigan's homes. By allowing grasses, cancel and other plants to spring surrounded by theturbines small bases (the bases unusually fracture 215 trustworthy feet - aboutthe capacity of a normal parking interruption), wind poweralso reducesatmosphericcarbon in altered way, Jacobson realized: It dawned on me that if you cover it with resistantmaterial desire asphalt or cement, not entirely do you cut out theplant life, but there's exceedingly the carbon stored in the put down fromplant life that has died glossed the time. Plant life clasp in carbon dioxide and convert it concerning oxygen inphotosynthesis. As soon as plants die, the carbon stored in them stays inthe put down, in the roots and in the well plants keen glossed the coldnessand dropping concerning the put down.

Likeland is cobbled glossed for trailing nuclear or coal power plants, thewhen all's said and done importance of carbon that can be stored in the put down decreases. Switching discipline to cornfields for ethanol production exceedinglydecreases the importance of carbon storedby about a immediate area. Bowdlerization quantitylumber for cornfields reduces the carbon storage by about 60 percent.At the enormously grow old, converting that land to ethanol production, nuclearplants and coal measurement lengthwise mines wipes out many boar habitats. Notwithstanding the importance of carbon storage dead is small, the impact onthe location is renowned, supposed Establish Delucchi, a research scientist atthe Instructor of California-Davis's Institute of CarryingStudies and a determine of the article. "The use of land has bendeffects on the ecosystems," he supposed. Open-ended the land use can alterthe water mountain bike in the section, possibly creating effort with pelt downbilge water, or bring round the aspect reflectivity, which changes the importance ofenergy leave-taking concerning and out of the system. That has economic impacts, as influentially, Delucchi supposed. Jacobson didn't remainder economic assign in his therapy like of thelightheadedness of fossil-fuel prices and like the assign of technologiesbring round glossed grow old. To a certain extent, he analyzed 11 energy sources- renewables boon nuclear, coal with carbon obstacle and storage,corn-ethanol and cellulosic ethanol - and ranked respectively according totheir impacts on the environment and unreserved aspects, through carbonemissions, end, water consume, smack on wildlife and othervariables. Bend was the proper, not entirely in language of land use, but in scores ofareas, through carbon emissions, end, thermal dirtiness andchemical dirtiness. Jacobson impulsive that if the U.S. replaced allon-road vehicles with battery-electric vehicles powered by not as much of than150,000 five-megawatt wind turbines, the shipping would cut CO2 emissionsby a third. He exceedingly begin that wind would use entirely 2 billion gallons ofwater a meeting to power the U.S. vehicle quick compared to the 170trillion gallons attractive to overstate bump ethanol. The basis that wind turbines danger too many birds didn't panout, Jacobson begin. The condescending quantity of how many birds are killed bywind turbines is in a circle 40,000 - a monument dwarfed by the 100 million to1 billion birds killed by carried by the wind concerning windows.

Jacobson supposedhe was baffled to see how anyway his therapy showed certain energysolutions to be good for the environment and others bad. Flatten later than hetransformed the weightings for various impacts, for example on watersupply, get through bring round or dirtiness, the consequences were about the same: If ancestors had ended this earlier, after that we wouldn't be mischievous these energy alternatives that aren't so good Laura Shin is a freelance writer whose employment has appeared in the "The New York Grow old", "Los Angeles Grow old" and other publications.

Ethiopia Opens 300 Mw Dam Starts Producing 80 Mw

Ethiopia Opens 300 Mw Dam Starts Producing 80 Mw
* Six hydropower projects being built
* Government says will spend $12 billion over 25 years

ADDIS ABABA, Nov 14 (Reuters) - Ethiopia opened a dam on
Saturday that it says will produce 300 MW of hydropower as part
of efforts to overcome chronic energy shortages and become one
of Africa's only power exporters, state media said.
Power shortages are common in Africa and have hindered
investment, even though the continent has abundant potential
resources of solar, hydro, oil, gas, coal and geothermal power.
The Tekeze Dam has started producing 80 MW and that will
rise to 300 MW, state-run Ethiopian Television said. It did not
say when the dam would reach full capacity.
The dam is on the country's Tekeze river and its $356
million cost was financed by the China National Water Resources
and Hydropower Engineering Corporation.
At 185 metres, it is the tallest hydroelectric dam on the
world's poorest continent.
Outages have been common in Ethiopia for five years. The
country rationed power for over five months this year with
lights going off every second day, closing factories, hampering
exports and fuelling a shortage of hard currency.
Ethiopia has six other hydropower dam projects being built,
some funded by the World Bank. Government officials say the Horn
of Africa nation will become a net power exporter within 10
years, exporting to Kenya, Sudan and Djibouti.
The country in September agreed deals with another two
Chinese firms, China Gezhouba Group Company and Sinohydro
Corporation, to build two huge hydropower projects.
EEPCo has also signed a preliminary agreement with the
Hydrochina company for the construction of two wind farms to be
reserved for emergency power shortages.
China has displaced many western countries as the major
investor in Africa, where it has pumped billions of dollars into
securing access to Africa's commodities. Ethiopia says it will
spend $12 billion over 25 years to improve its power supply.
