The intermittent nature of many renewable forms of energy are already giving some problems to utility grids.  New energy storage systems will need to be developed to go with the surge in the use or renewables such as wind.  Sodium-sulfur batteries and flywheels are commercially available and...

There are two rules (left from the Jimmy Carter era) for picking biofuel plants: 1. Never use food 2. Never use land that could grow food      I would add a third: 3. Make sure the amount of fossil fuels used to grow and process the fuel is significantly less than...

Distributed energy as well as energy conservation will be very important in any future planning of electrical generation and distribution. Hydrogen will not plan any part significant in distributed energy systems in the foreseeable future since there are still many problems ...

Carbon sequestration will be a costly and complex technology to implement. It is unclear that one of these system added to a coal fired power plant will ever make the plant competitive with wind and other renewable energy sources without major and continuous government subsidies.

The Chinese government is very aware of the need to cut their carbon footprint while at the same time improving the lifestyle of their citizens.  They have already created a large “cottage” industry producing millions of solar water heaters and now are building large new factories to produce...

Nuclear power plants need fuel, just like fossil fuel power plants. Uranium, the fuel of choice for nuclear power plants is a finite resource that is becoming in short supply, and the proposed construction of large numbers of new nuclear power plants will make the problem much worse. The sources of...

      One problem with renewable is the variability of the available power from wind and solar sources.  Major penetration of greater than 25% by solar or wind energy of a utility grid’s entire power output will require some sort storage incorporated in the system. ...

     The evidence for global warming is now so overwhelming that business and financial managers can no longer ignore it.  Carbon trading is probably the fairest way to reduce the carbon footprint of the developed nations and encourage the developing countries to use renewables...

Konarka Corp. in MA has the expertise to finally create a viable commercial product using semiconducting polymers doped with organic dyes.  While the system promises to be very inexpensive, relatively efficient and flexible, there are some concerns about the longevity of these thin, flexible photovoltaic...

Cadmium Telluride is an excellent material to use in photovoltaic (PV) cells, with very little of the material needed in the thin film (~1 to 2 micron) PV cells.  However, although the material has been known as a PV material for many years, it has suffered from low efficiency and has been relegated...
