The Potomac Energy Project is an effort to develop and distribute the most advanced energy technologies currently available through unclassified research projects. These technologies will streamline private and government efforts to reduce dependency on hydrocarbon resources, while also reducing the negative impact of energy consumption on the environment.

Green investments are traditional investment vehicles (such as stocks, exchange-traded funds and mutual funds) in which the underlying businesses are involved in operations aimed at improving the environment. This can range from companies that are developing alternative energy technology to companies that have the best environmental practices.

A French company has developed a pollution-free car which runs on compressed air and India's Tata Motors has the car under production and it may be on sale in Europe and India by the end of the year. The "air car", also known as the Mini-CAT (Compressed Air Technology ) or City Cat, can be refueled in minutes from an air compressor at specially equipped gas stations and can go 200 km on a fill-up and the top speed will be almost 70 mph.

Many sources of energy are being wasted. This can be in the form of building air conditioners or refrigeration units that vent heat to the atmosphere, or even the heat given off automobile engines. The U.S. Department of Energy reports that the available seven quadrillion Btu of waste heat sources exceeds the current production of all other U.S. renewable power sources combined. This includes hydroelectric, wood, biofuels, geothermal, wind and solar photovoltaic.

Thanks to Al Gore, we all know by now about the increasing concentration of carbon dioxide in the atmosphere and the resulting impact on global climate.
Now, 2 researchers from UCSD have developed a prototype device that can capture energy from the sun, convert it to electrical energy and “split” carbon dioxide into carbon monoxide (CO) and oxygen.

We've used wind as an energy source for a long time. The Babylonians and Chinese were using it to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages to grind corn, which is where the term "windmill" comes from.
Although wind currently produces just over 1% of world-wide electricity use, it accounts for approximately 5-20% of electricity production in some European countries.

The quest for alternative energy is the gold rush of the twenty-first century. And as with any gold rush, the companies that sell miners their picks and shovels are the ones with the best chance of success. FirstLook is that kind of company. Instead of digging tools, it sells detailed reports to new-energy entrepreneurs. Those reports show just how much wind or sunshine an area is likely to receive, based on years’ worth of meteorological data.

Turning plants such as corn, soybeans and sunflowers into fuel uses much more energy than the resulting ethanol or biodiesel generated, according to a Cornell University and University of California-Berkeley study. The World desperately needs a liquid fuel replacement for oil in the near future, but producing ethanol or biodiesel from plant biomass is the wrong way to do it, because you use more energy to produce them than you get out from the combustion of these product.

Ethanol is a rather controversial technology. While many automotive companies are heavily investing in developing ethanol production, releasing ethanol vehicles, and building up the ethanol infrastructure, the process has been much maligned by the United Nations and academia. The UN and various professors have released regular statements blasting the technology for threatening to raise food prices on basic food stocks such as corn. They say that this is already happening, and is causing an increase in famine worldwide.

Algae is the cheapest, highest yielding feedstock for biofuels and biomass for energy. It accumulates waste toxins, grows from polluting waste, does not require conversion of food crops to energy, does not lead to deforestation, and voraciously consumes carbon dioxide. Algae can produce lipid oils for biodiesel, carbohydrates necessary for ethanol, generate hydrogen, generate methane for electrical generation, be used as fertilizer, animal feed, and co-firing in coal electrical plants. Best of all, the energy produced by algae products is carbon neutral as the algae biomass is produced from CO2 in the atmosphere present today.
