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.

More Attempts To Kill Wind Power In Delaware

More Attempts To Kill Wind Power In Delaware
Delmarva Power and Harris McDowell have showed up this week with buckets full of fresh coffin nails intended to kill the Bluewater Wind project. McDowell yesterday circulated a draft of his report purporting to show that we can't afford offshore wind. According to the News Journal, the draft criticizes the reliance on a long term power purchase agreement (PPA) and suggests that the project instead be configured to make use of a state government incentive: Copeland added that the draft report by McDowell's committee recommended Delmarva Power purchase onshore wind power and Delaware offer Bluewater a one-time incentive to build the project without other state-imposed guarantees.

The aid, Copeland said, would be similar to New Jersey's recent offer of up to 19 million to support private offshore wind ventures. New Jersey's approach obliges developers to find their own buyers for electricity generated by Garden State turbines.There is no word on whether Copeland plans to introduce legislation to offer state money to Bluewater. The assertion that New Jersey project won't rely on a PPA is of course a fantasy, but one that McDowell and Copeland hope will appeal to those who want to oppose the project while maintaining that they really do like wind power, really.

On Tuesday, Delmarva Power distributed the following prices sheet to members of the General Assembly:

That's it. No explanations. No disclaimers. No basis for comparing the numbers. Delmarva's one pager comes without the fine print--the kind of disclaimers you hear at the end of TV or radio ads in which words are compressed to the point of incomprehension: "These virtual wind prices do not include transmission costs, reliability calculations or any actual environmental benefits for Delaware..."

As they are, the numbers are at best useless, and can be better described as misleading. We are given nothing to help us to understand whether and how the numbers are comparable, because no basis for comparison is offered.

One example: We know onshore wind is less reliable, so an equal capacity should not result in equal output. You may recall that reliability is an issue of great concern with Delmarva when it comes opposing the Bluewater project. Apparently it's less of a concern when it comes to these bids.

For Gary Stockbridge and his colleagues at Delmarva Power it's a great solution: They wouldn't have to swallow the Bluewater project, they spend less of the company's money, and they get to claim they like wind power even though it's not clear whether the onshore wind turbines have actually been built.

It's not as though the McDowell report and Delmarva Power's onshore wind bids haven't been expected. But opponents will seize on these long planned developments as reasons to kill or at least delay the project.

We will see whether these developments are enough to hold up consideration of HCR 38 in the House, which could come today. The common thread of these ham-fisted attempts to kill offshore wind is the assertion that the project is too expensive. But, as I have pointed out, the project would cost us extra if and only if fossil fuel prices take a nosedive and stay depressed for years to come.

It has been two years since HB 6 was signed into law, and nearly eleven months after the Public Service Commission directed the company to open negotiations with Bluewater Wind, and those who would uphold Delmarva Power's status quo are doing all they can to keep Bluewater Wind from making Delaware the first state to build offshore wind.
