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.

Harris Mcdowell Report A Foregone Conclusion

Harris Mcdowell Report A Foregone Conclusion
Harris McDowell is having trouble getting his colleagues on the Senate Energy ">But because McDowell is only one member of the committee, we don't yet know what the report will say. It may take another couple of weeks for it to be toned down enough to gain approval from the committee's membership. But that hasn't stopped some insiders from leaking the report to media, such as WDEL, which ran this story on Friday:

More details are coming to light as to why the Senate Energy and Transit Committee may suggest killing the proposed deal for an off-shore wind farm.

In a draft report obtained by WDEL News, the committee concluded the process of selecting the proposed Power Purchase Agreement between Delmarva Power and Bluewater Wind didn't allow for its comparison to other more beneficial and less costly options. Of course the process didn't compare these options, because the competitive process was based on a law, HB 6, that set the criteria for selecting a new, in-state energy source.

It also states the agreement would create a net economic loss for the state in terms of jobs and disposable income. As I have said many times over, the calculation that the wind farm would cost ratepayers more is based on the unlikely premise that fossil fuel prices will go down in the next several years and stay down for years to come. By the way, I and others have said this to the committee, in person, on paper and in electronic form, so I don't think they may have overlooked the point.

The report says committee recommendations include instructing the Controller General to vote against the agreement, and the General Assembly monitor a new process that includes competitively bid, long-term contracts, for renewable energy, including on-shore wind. Strictly speaking, the draft report cannot refer to committee recommendations until such time the committee actually votes on the report.

There are further reasons for discounting what the report may eventually say, if and when it gains approval of the committee.

We know that committee chair Harris McDowell has been an unrelenting opponent of the offshore wind proposal.

We know he has stacked his hearings with opponents on the wind farm. His invited guests were invariably opposed the project, and given the first speaking slots while proponents were told to sign up to testify. In my case, even signing up by e-mail didn't guarantee a speaking slot.

We know McDowell spent public funds to hire a pricey lawyer to interrogate the leadership of the Public Service Commission, whose transgression was implementing HB 6, which the General Assembly had passed two years ago.

We know he brought in an outside expert, Michael T. Hogan, to point out the errors of our ways for even considering building an offshore wind farm in Delaware. (Some readers of this blog may remember Mr. Hogan for his emphatic attempts to dissuade us from the folly of offshore wind.) By the way, I don't think that paying Mr. Hogan's expense likely affected his testimony; I think he was asked to testify because McDowell knew what he would say in advance.

All this is academic because there is, as yet, no committee report. But while McDowell and his allies can't gain approval for a one-sided draft report, they can leak their version to the media without the bother of a committee vote.

I would expect that these leaks will continue. In the meanwhile, I also expect that our local media will consider the source of the leaks, and be mindful of the fact that the report reflects nothing more than the concerted efforts of wind power's most determined opponents to kill the Bluewater project.
