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.

An Open Letter to the Legislative Leaders of Delaware:


For a number of months, representatives of the organizations listed above have worked to raise the level of public awareness about the health and environmental impacts associated with fossil fuel power production. Over this same period, we have witnessed the release of the Fourth Assessment of the International Panel on Climate Change (IPCC), which offers a dire picture of our future if we fail to undertake immediate and

aggressive measures to reduce carbon emissions, the major cause of global warming. Coal-fired power plants, which now produce more than half of the nation's electrical power, are the largest source of carbon and toxic air emissions in Delaware and throughout the country.

We support the aggressive adoption of energy efficiency and conservation measures. However, we recognize that new power production from renewable energy sources also will be required. We have been evaluating the benefits of offshore wind energy as a clean, non-carbon emitting alternative energy source. Our members have spent countless hours reviewing documents and getting educated on the complexities of utility regulations and economics.

Most of our organizations are comprised of volunteers who have no other interest than ensuring the best possible outcome for the citizens of Delaware. We believe the Public Service Commission and other decision-making agencies should direct Delmarva Power to enter into a long-term Power Purchase Agreement to construct the proposed offshore wind energy project.

We are convinced that, while this project may initially cost a little more than fossil fuel-based energy, in the long run there will be an overall cost savings, not only in terms of reduced rates and stable prices, but in healthcare and environmental costs as well.

While both land-based and offshore wind energy are far superior to fossil-fuel energy sources, land-based wind energy alone will not be able to satisfy increasing requirements for renewable energy by states and the federal government. Delaware's land-based wind energy resource is extremely limited. However, nearly 80% of the nation's high-quality, near-shore (less than 30m depth) wind energy resource is located in the Mid-Atlantic coastal region. This geographic advantage represents a huge economic development potential for Delaware that would help diversify our economy, provide a new source of high-skilled, well-paid jobs, and offer a new revenue stream to the state from power exports.

This issue will go before the Public Service Commission on December 18th. It is critical that Commission members and the other decision-making agency representatives support the offshore wind energy project. We urge you to instruct Controller General Larson, as your representative to these proceedings, to vote in favor of the Power Purchase Agreement currently before them.

Difficult decisions require strong leadership. We must take control of our energy future.

Nicholas A. DiPasquale Nick is conservation chair of Delaware Audubon. He previously served as Delaware's secretary of Natural Resources and Environmental Control.
