Long term, safe returns do not lie in oil exploration and development.  Or in nuclear power investment. Or in "clean" coal.

The new energy economy is a better, safer investment.  As renewable/conservation smart grid technology lowers oil demand and electricity demand itself, and plentiful renewable supply takes over energy markets, money is safe in the leading suppliers of these new energy devices.

Money in the old energy economy companies will evaporate and condense in the hands of investors in the new paradigm.  And so it goes.

ECD company press release:

"Energy Conversion Devices, Inc. (ECD) (Nasdaq: ENER) is the leader in building integrated and commercial rooftop photovoltaics, one of the fastest growing segments of the solar power industry. The company manufactures and sells thin-film solar laminates that convert sunlight to energy using proprietary technology. ECD's UNI-SOLAR(R) brand products are unique because of their flexibility, light weight, ease of installation, durability, and real-world efficiency. ECD also pioneers other alternative technologies, including a new type of nonvolatile digital memory technology that is significantly faster, less expensive, and ideal for use in a variety of applications including cell phones, digital cameras and personal computers."

This is just one example of why investment in oil is a dead end.  Roofs can power the world.  With a little help from wind and ground heat exchange and battery powered transportation.  

And help from smart grids that form the circulatory and nervous system of the new renewable energy/information techonology economy.

A gradual transition over 10 to 20 years will produce a sustained healthy growth, not just a bubble that can burst without warning.  ECD or companies like it can cover the rooftops all over the planet by then, incrementally year after year.
